I Receive Email But Cannot Send it Out – Why?
Ask any network administrator what is the most frequent customer question, and the likely answer is email.
The most popular email method uses two different services that work together, called POP and SMTP. POP (Post Office Protocol) receives email, and SMTP (Simple Mail Transport Protocol) sends email. Most people don’t have trouble receiving email, and when they do it’s usually because someone sent them a huge file, but problems with sending email are far more common.
This is because the majority of large Internet service providers have set up safeguards in an effort to limit the amount of unsolicited email on their networks. Unfortunately, these safeguards often cause problems for legitimate users. For example, Cablevision’s Optimum Online service, will only allow outgoing email using its own SMTP server, mail.optonline.com, which works on the default SMTP server setting,TCP port 25.
So if you tried to send out email from your company laptop on an Optimum Online without using the Optonline SMTP server, your email would be stuck in the outgoing mailbox and you will probably get error messages referring to the SMTP server.
Changing the SMTP address in your email program is a straightforward process. If you are using Microsoft Outlook or Outlook Express, locate “Tools” from the top menu and then select “E-Mail Accounts” or “Accounts” depending on the version you are using. Then select the email account you want to access. Next hit the “Change” button and you will see the text area where you can change the SMTP address. (Note that all versions of Outlook and Outlook Express have different layouts, but the SMTP settings is always found in the “Tools > Accounts” menu.)
In the case of Optimum Online, we will need to the change the SMTP address to “mail.optonline.net”. We also had to click on the “More Settings” button, which opened up a tabbed menu, from which we selected the “Outgoing Server”. We then selected thecheck box next to “My outgoing server (SMTP) requires authentication” and below it choose the radio button for “Use the same settings as my incoming mail server.”
Almost every major ISP, including Verizon, Time Warner, Earthlink, requires a similar configuration. You can usually find out how to configure Outlook by looking in the support section of the ISP’s website. (To no surprise, the sections covering email are usually very extensive and include screenshots.) or by calling the ISP’s support department.
A problem with using the ISP’s email settings is they will only work when you are on that network. If you decide to bring your laptop to Starbucks or the office, you will need to change the SMTP configuration again.
But there is a way to work around the SMTP issue. Google allows Outlook users to send and receive email using POP and SMTP with its Gmail service. Gmail avoids the default SMTP port 25 used by all the bigISPs and instead uses TCP port 465 for SMTP. For incoming email using POP, Gmail uses TCP port 995 rather than the standard TCP port 110.
Gmail accounts are free and also have excellent spam filtering. If you need a second personal email account of if you want to switch your primary email to another provider and not have worry about whether you can send and receive email on a certain network, Gmail is an excellent choice.
So the next time, you plug your laptop into a new network and start getting email errors, the first place to look is the SMTP settings.
This is a list of SMTP settings for a few of the larger ISPs.
Time Warner (Roadrunner) smtp-server.nyc.rr.com
AT&T imailhost.worldnet.att.net (DSL) mailhost.att.net (Dial-up)
Comcast smtp.comcast.net
EarthLink smtpauth.earthlink.net
MSN secure.smtp.email.msn.com
Mindspring mail.mindspring.com
Netzero smtp.netzero.net
Optimum Online (CableVision) mail.optonline.net
Verizon outgoing.verizon.net or smtpout.verizon.net
Yahoo Hotmail – Configure Hotmail For Yahoo Mail
Let’s talk about making a Yahoo Hotmail connection. As a Hotmail user, you know all the great benefits of this service, things like Spam Bodyguard and Hotmail for Mobile. But did you know you can bring all your different email accounts together into your Hotmail Inbox?
It’s true. For virtually all major email services, there is a way to get your messages to come into your Hotmail Inbox. Think about how easy things will be when you only have one place to check your email! You can configure Hotmail for Yahoo email access in minutes to complete a Yahoo Hotmail connection.
Setting this up is simple. But there’s one minor issue to deal with first. Yahoo will only allow you to make a Yahoo Hotmail connection with a premium Yahoo email account. Unless you are trying to set up some kind of major corporation, that means you will need to upgrade your free Yahoo Mail account into a Mail Plus account.
While this might be annoying, it’s fast and simple to upgrade your existing Yahoo Mail account. And in case you were worried: you don’t have to change your email address.
Once you have your Yahoo account upgraded, this is like a 10-minute job. If you’ve ever installed any software on your computer yourself, you will be able to get this done in no time. All you need is quality directions for getting the job done.
Because things change all the time in the world of computers, you’ll need to go online for the most current instructions. In particular, you want instructions that take you through the entire process, from beginning to end, including upgrading your Yahoo account.
And those instructions should be specifically for getting your Yahoo Mail in your Hotmail Inbox, not the generic stuff you find at many websites. Eliminate all the hassles and guesswork by getting exactly the right instructions for the task at hand.
Yahoo Outlook 2010 – Configure Outlook 2010 For Yahoo Mail
Outlook 2010 is the newest email powerhouse from Microsoft. One of its many talents is the ability to manage multiple email accounts at once. That means it allows you to work with all your email without ever leaving Outlook. It takes only minutes to configure Outlook 2010 for Yahoo email and establish the Yahoo Outlook connection.
Unfortunately, there is an issue to deal with when you try to get Yahoo and Outlook 2010 working together. A Yahoo Outlook connection requires you to have a premium Yahoo email account. That is, you must have a Yahoo Mail Plus account or a Yahoo Business Email account.
For whatever reason, Yahoo decided years ago not to allow any third party email programs (such as Outlook) connect to the Yahoo Mail servers with a free account. In a more positive light, converting your current Yahoo Mail account into a Yahoo Mail Plus account is fast and simple. And no one you correspond with will even notice the difference.
If you are using your Yahoo email account for business, you might want to consider a Yahoo Business Mail account. These are more expensive than the Mail Plus accounts, but have some potential advantages for business users. Actually configuring Outlook for Yahoo Mail follows almost the same process as for Mail Plus.
Do you sometimes install software on your computer or otherwise make changes to the way it works or what is running on it? If so, you are capable of setting up either a Mail Plus or Business Mail account for yourself.
The instructions for doing this aren’t tough, but they are a fair number of steps involved. In addition, the exact steps you need to follow vary depending on which version of Outlook you are working with. The smart move is to get a current set of instructions to be sure all goes smoothly. The ideal instructions will take you through every step of the process, from converting your free Yahoo email account into a Mail Plus account, to the exact steps needed to configure Outlook 2010 for Yahoo Mail.
DNS Tutorial – A Guide to Understanding DNS and Zone Records
DNS in a nutshell
As I said above, DNS is a translation service from computer readable names, to human readable names. The theory is similar to a phone book, or directory assistance, which translate phone numbers to names. The DNS system is distributed across the whole Internet, virtually every Internet provider has two or more DNS servers, most hosting companies do as well, and a lot of large businesses, ie Microsoft, Dell, HP all have their own servers. (of course, having 30,000+ employees, they probably have their own directory assistance too).
Every single person on the Internet uses DNS, 99% of them without even knowing. Every time you go to a website, you do a search of the DNS system to find the location of the site. Every time you send an email, your ISP’s mail server does a DNS search to find the mail server for that domain. As I said, DNS works on a distributed basis, no one server holds the records for every single domain. There are a lucky 13 master servers, that contain a list of which DNS servers handle which domains, when you look for a domain that your ISP’s DNS server does not know, it asks the master servers, which DNS server does know about this domain, then it asks that DNS server for the information it needs, before passing it back to you.
Changing DNS Servers
When you change hosting providers, the normal procedure is to also change your domain’s delegation to the new hosting providers DNS servers. This procedure, known as redelegation, is best, as it means one company handles everything for you, and if they make a change to the location of your website, for instance moving it onto a faster server, they can also update the DNS records straight away, so no one notices. To find out who your domain is delegated to, you need to do a ”whois search”. A whois search will not show you where your website is, but it will show you which DNS servers know where it is. Customers of Anchor should always see ”’ns1.anchor.net.au”’ and ”’ns2.anchor.net.au”’ in their whois information. If your domain is currently with another company, and you need to bring it to Anchor, you need to change that information. Generally, this is done through a web page of the company that you registered the domain with, it is a simple change.
Once the change is made, depending on the type of domain, it can take up to 3 days for the rest of the Internet to notice you have moved. (The same as when you move house, it can take quite a while for other people to realize). The reason for this is explained in the next paragraph. Suffice to say, for a period of 3 days, some people will see the new site, some people will still see the old one. Some email will go to the new server, some will go to the old server. This is avoidable through careful planning, and a week long changeover.
Buzzwords & Geek words, translated!
Often when talking about DNS, the words (and abbreviations), ”’TTL”’, ”’Cache”’ and ”’Propagation”’ come up, but what do they mean? In plain English, the DNS server responsible for your domain has a file with all the information about your domain in it, and when another DNS needs information about your domain it is pulled from this file, along with a TTL value. TTL stands for ”’Time To Live”’, and it is the maximum time a foreign DNS server can store this information locally, without asking if it has changed (the process known as caching). When you redelegate your domain from one DNS server to another, the amount of time it takes depends on the TTL value in the old server. If this value is high, which it generally is (around the 1 day mark) then any DNS server that has requested information on your domain in the past 24hrs will still see the old records; once the TTL period expires the servers will then see the new details.
Additionally for ”’.com, .net, .org”’ domains, no server will see the change until the DNS system reloads at midnight, USA time, whilst the ”’.au”’ domains are updated instantly. This process of waiting for all the Internet to see your move is called propagation. As I said above, there is a way to speed up the process, and that is to redelegate a week early with your new hosting company copying the old records, with a very low TTL, (ten minutes or so), and then when you are ready for the website and email to go to the new server, changing them on the new DNS server. This means the whole Internet will see the change in 10 minutes, regardless of the domain name (note, some ISP’s do not confirm to the standard for DNS caching, and may not update instantly).
So what does a domain record look like
@ IN SOA ns1.anchor.net.au. hostmaster.anchor.net.au. (
2004030401 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
@ IN NS ns1.anchor.net.au.
IN NS ns2.anchor.net.au.
IN MX 50 smtp1.anchor.net.au.
IN MX 100 smtp2.anchor.net.au.
IN A 202.4.234.122
smtp IN A 203.98.94.10
www IN CNAME @
ftp IN CNAME @
mail IN CNAME smtp
pop IN CNAME smtp
pop3 IN CNAME smtp
That looks scary! What does it all mean?
Lets breakdown the file one line at a time
@ IN SOA ns1.anchor.net.au. hostmaster.anchor.net.au. (
This line, the Start of Authority, states that ns1.anchor.net.au is the domain server responsible for your domain, and that
hostmaster@anchor.net.au is the contact for this server
Skip the next 4 lines: ”’Expire, Retry, Maximum and Serial”’, as these are not important in this situation
86400 ) ; Minimum
The value of minimum is the TTL, ie the length of time, other servers can cache the information for your domain
@ IN NS ns1.anchor.net.au.
The third column on this line, NS, means nameserver, this line means that your server is listed in ns1.anchor.net.au (and below that in ns2.anchor.net.au). NS lines give a list of all the nameservers responsible for your domain.
IN MX 50 smtp1.anchor.net.au.
Again, the column after IN is important, (all your records should say IN), MX stands for Mail eXchange, and MX lines are a list of servers that handle your email, the number after MX is the priority, the lower the number, the higher the priority
IN A 202.4.234.122
On this line, A means Address. All A records are direct translations of names to numbers. If the line starts with a word, that is a host name, ie ”’http://www.yourdomain.com.au”’. If it doesn’t have a word, it means just ”’yourdomainname.com.au”’. If it has a * it means every subdomain of ”’yourdomainname.com.au”’ that’s
available.
mail IN CNAME smtp
The final record type is CNAME, whilst this stands for Canonical Name, it is often easier to think of it phonetically, ie; See-Name. As thats what it means, in this case, the record tells computers looking for mail.yourdomain.com.au to go look for smtp.yourdomain.com.au instead.
Now don’t you feel enlightened?
Do I have to have this? It all seems so complicated
If you want people to see your website, and email you, you must have DNS records. It is unavoidable. However as I said at the start of this article, you only need to have an understanding of the top level of the system, ie, when I redelegate, it takes 3 days, my email will be scattered. You do not need to understand how the entire system works, that is the job of your DNS administrator (often called hostmaster), who is typically your web hosting company.
Can I do this myself?
If you have a static IP address and a permanent Internet connection you can host your own DNS, and if that doesn’t make any sense to you, you are probably better off letting someone else handle it. You may notice in a whois search that most domains have 2 DNS servers listed, and some have up to 10. This is for redundancy: if one server dies, but the others are still working, then your website and email are unaffected; but if you only have one server, and it goes down for whatever reason, then your email and website are offline too.
Seven Layers of ISO OSI Model
The ISO OSI model are explained below. The seven layers of the OSI model are:
Application
Presentation
Session
Transport
Network
Antiqua”>Data Link
Physical
1 Application layer:
This layer provides a means for the user to access information on the network through an application. Many user applications that need to communicate over the network interact with the Application layer protocol directly. The user applications are not part of OSI Application layer, use the networking services offered by the networking protocol suite. Application layer functions typically include identifying communication partners, and determining availability of required resources. Some examples of application layer implementations include Telnet, File Transfer Protocol (FTP), and Simple Mail Transfer Protocol (SMTP).
2 Presentation layer:
Presentation layer converts local host computer data representations into a standard network format for transmission on the network. On the receiving side, it changes the network format into the appropriate host computer’s format so that data can be utilized independent of the host computer. ASCII and EBCDIC conversions, cryptography, and the like are handled here.
Examples of Presentation layer coding and conversion schemes include common data representation formats, conversion of character representation formats, common data compression schemes, and common data encryption schemes.
Presentation layer implementations are not typically associated with a particular protocol stack. Some well-known standards for video include QuickTime and Motion Picture Experts Group (MPEG). QuickTime is an Apple Computer specification for video and audio, and MPEG is a standard for video compression and coding.
3. Session layer:
The session layer establishes, manages, and terminates communication sessions. Communication sessions consist of service requests and service responses that occur between applications located in different network devices. These requests and responses are coordinated by protocols implemented at the session layer. Some examples of session-layer implementations include AppleTalk’s Zone Information Protocol (ZIP), and Decent Phase Session Control Protocol (SCP).
4.Transport layer:
Transport layer is responsible for providing reliable service between the hosts. Upper layer datagrams are broken down into manageable datagrams and then appropriate header information (such as sequence number, port number, etc.) is added to the datagram before passing it on to the Network layer. Two frequently used transport protocols are the TCP (Transmission Control Protocol) and the UDP (User Datagram Protocol).
Important features of Transport layer:
Transport layer ensures reliable service.
Breaks the message (from sessions layer) into smaller datagrams, and appends appropriate unit header information.
Responsible for communicating with the Session layer
Important features of TCP/UDP:
TCP/IP widely used protocol for Transport/Network layers
TCP: (Transport Control Protocol) TCP ensures that a packet has reached its intended destination by using an acknowledgement. If not, it retransmits the lost messages. Hence, TCP is called a connection oriented protocol.
UDP (Universal Data gram Protocol): UDP simply transmits packets over the internet. It does not wait for an acknowledgement. It is the responsibility of upper layer protocols to ensure that the information had reached the intended partner(s). Hence, UDP is often called connectionless protocol.
Application programs that do not need connection-oriented protocol generally use UDP.
5. Network layer:
Network layer is responsible for the routing of packets through the entire network. The layer uses logical addressing for this purpose. Note that the physical address (like MAC address) keeps changing from hop to hop when a packet travels from source to destination. As a result, an address that doesn’t change is required to ensure continuity between hops. This is nothing but logical address. For IP networks, IP address is the logical address; and for Novell network, IPX address is the logical address, and so on. This layer also provides for congestion control, and accounting information for the network. IP (Internet Protocol) is an example of a network layer protocol.
6. Data link layer:
Data link layer provides delivery of information frames between communicating partners. This layer is responsible for flow regulation, error detection and correction, and framing of bits for transmission. The network data frame is made up of checksum, source address, destination address, and the data itself. The largest frame size that can be sent is known as the maximum transmission Unit (MTU).
Important features of Data link layer:
Assembles bits into frames, making them ready for transmission over the network.
Provides error detection, and correction to transmitted frames. If the checksum is not correct, it asks for retransmission. (Send a control message).
Consists of two sub layers:
Logical Link Control (LLC): Defines how data is transferred over the cable and provides data link service to the higher layers.
Medium Access Control (MAC): Controls media access by regulating the communicating nodes using pre-defined set of rules. (i.e. Token passing, Ethernet [CSMA/CD] all have MAC sub-layer protocol).
Different Data link layer protocols define different network and protocol characteristics, including physical addressing, network topology, error notification, sequencing of frames, and flow control. Physical addressing (as opposed to logical addressing) defines how devices are addressed at the data link layer. The protocols used in Data link layer are SLIP, PPP, and CSLP.
7. Physical layer:
This is the bottom-most layer of the OSI model. The Physical layer handles the bit-level communications across the physical medium. The physical medium could be made up of wired electrical signals, or light, or radio (wireless) signals. Physical layer specifications define characteristics such as media, data rates, maximum transmission distances, and physical connectors.
Some of the important standards that deal with physical layer specifications are:
RS-232(for serial communication lines), X.21, EIA 232, and G730.
Physical layer and Data link layer implementations can be categorized as either LAN or WAN specifications.
Cell Phones For the Deaf – Data Only Cellular Plans
For deaf individuals or for those with significant hearing loss, cell phones can still be a great way of staying in touch. By selecting hearing aid compatible cell phones, those with a mild to moderate hearing loss can often make use of these handy communication devices especially when a neckloop, amplifier, or an induction coupler known as Hatis is added. For deaf individuals or those with a more severe hearing loss, the ability to use text messaging features is critical and the use of voice calling frustrating or useless. In such instances, paying for costly voice plans makes no sense when the individual can only make use of the data features.
Fortunately, some of the major US cellular providers now offer data only plans that can be purchased without any voice plan required. T-Mobile offers the Sidekick Data Plan which offers unlimited e-mails, messaging, web surfing, and instant messaging for only $29.99/month. AIM comes installed on the phone and users can download Yahoo!Messenger. Users can also sync up to three of their POP3 e-mail accounts to their cell phone and they receive a free tmail.com account with 6MB of storage. Voice calls, if needed, would be charged at 20 cents/minute.
AT&T offers the Text Accessibility Plan (TAP) for iPhone. This plan includes unlimited SMS messages, unlimited data usage (e-mail and web) as well as visual voice mail for $40/month. Any voice calls would be charged at 40 cents/minute. The AT&T site indicates that potential users need to complete a Disability Certification form, sign up for regular iPhone activation via iTunes, and then contact AT&Ts National Center for Customers with Disabilities to change their service to the TAP plan for iPhone. Availability is sparse in Alaska as well as parts of the western US.
Sprint provides the Sprint Relay Data Plan. This $29.99/month plan provides unlimited e-mail, internet access, instant messaging, domestic text messaging (SMS), and unlimited Phone as Modem. Incoming and outgoing calls are blocked to avoid any unwanted expenses. This block can be removed by the user and voice calls would then be charged 20 cents/minute for local calls and 40 cents/minute for long distance. Users can get this plan only via the Sprintrelaystore.com site.
US Cellular offers a number of data only plans. They have a “Standard Wireless” plan for $24.95/month which provides unlimited text messaging and, if needed, voice calls for 25 cents/minute within area and 69 cents/minute when roaming. For those interested in a plan without a contract or any credit checks, they also offer a Prepaid Plan. This $24.95/month plan also gives users unlimited text messaging but any voice calls are charged at 50 cents/minute in area and 69 cents when roaming.
For those wanting additional data services, US Cellular offers the Blackberry Plan which provides unlimited texting messaging for $14.95 and e-mail and web service for an additional $44.95/month. Any voice calls are charged at 99 cents/minute. Users get not only text messaging but Yahoo!Messenger, GoogleTalk Messenger, and Blackberry Messenger as well as the ability to link up to 10 personal POP3 e-mail accounts. The final offering is their Windows Mobile plan which provides unlimited text messaging for $14.95/month and Windows Mobile e-mail and web for an additional $29.95. Users get the Microsoft OS with Internet Explorer web browsing, MSN Instant Messenger and the ability to link up to 8 messaging and e-mail accounts.
Data only plans make sense and certainly there are at least a handful of options available; making cellular based communication a more affordable option for the deaf and hearing impaired.
Choosing the Best Email Hosting for Your Business
Email hosting may not seem like a big deal to you, considering
all of things to think about when launching a new internet
business, but trust me when I tell you that problems with email
is one of the most frustrating things you’ll ever deal with in an
internet-based business.
In an internet-based business, the majority (if not all) of your
communications with customers are conducted via email.
Sure, some internet-based businesses have phone service and offer
their phone numbers to customers and potential customers for the
purpose of asking questions, calling in orders or obtaining
support.
But, the online customer is more apt to contact an internet-based
business via email or through the use of contact forms provided
on the business’s website.
Notification of communications submitted through online contact
forms or order forms are also generally presented to the business
in the form of email.
As you can see, the very nature of an internet-based business
makes it highly dependent on email, not only as a medium for
communications, but also for operations.
Email difficulties or downtime can literally shut an internet-
based business down causing lost sales and poor customer service.
Lost revenues and customer dissatisfaction are the results, not
to mention the aggravation and resulting frustration.
Looking at things from that realistic angle, you can see that
email hosting is a business function that not only deserves, but
demands your attention.
So, you’re probably asking, “What are the aspects of email
hosting that need my attention?”
In most cases, you won’t choose an email host independent of your
web host because most businesses do (and should) use email
addresses that contain their domain name.
You can have an email host that is separate from your web host,
but there is really no reason for it since the hosting of email
is generally a feature of web hosting packages.
I definitely do not recommend using free email services for your
business communications. YourCompanyName@hotmail.com – seriously,
how professional is that?
When you use the email options that are part of your web hosting
plan, your domain name will be part of your email address which
will present a much more professional image.
Other advantages of using professional versus free email hosting
services are enhanced options and fewer limitations.
When choosing a web host, you should be concerned with the
hosting company’s secure server capabilities, the speed of their
servers, the space you are allowed on the server, and the access
alternatives they provide.
Access to server logs and reports is important as is the
availability of certain scripts and software. You also want to
make sure that your web host has been in business for awhile, is
well established and is reliable.
A good web host or email host should be able to guaranty at least
99% uptime since downtime can be a serious hindrance to your
internet-based business.
The web host’s backup procedures are also of importance as is
their technical support services.
In regard to email features that accompany your website hosting
package, full email services should be provided.
Email services should include unlimited email aliases, the
ability to set up auto-responders, and web-based access and
administration features.
If you exchange files via email, it is important that there are
no restrictions on the size or type of files that you can
exchange. And of course, reliability is crucial as is immediate
access to technical support when you need it.
Email hosting that uses IMAP technology is a fairly new and
highly desirable solution for your business’s email needs.
Historically, POP (Post Office Protocol) has been common for
receiving email with SMTP (Simple Mail Transfer Protocol) being
used for sending email.
IMAP (Internet Message Access Protocol) is a nice alternative to
POP for receiving email.
With POP mailboxes, when you retrieve your email from your server
through an email program such as Outlook or Outlook Express, the
messages are generally removed from the server when they are
transferred to your personal computer.
This can be a problem if you use more than one computer, a
desktop and a laptop for instance. With IMAP mail receiving
capabilities, your message are archived on the IMAP server and
you can access and view your messages using a client program
without removing the messages from the server.
Hide My Ass Review – What Is Hide My Ass?
Hide My Ass is a VPN provider with a funny name but that provides a very serious service. The service allows people to anonymize their Internet traffic for security.
What Services Like Hide My Ass Do
Hide My Ass is one of many VPN providers that allow users to connect to Internet sites through servers other than their own ISPs. You still use your ISP, of course, but any traffic going to the website you want to visit appears to be coming from a different server entirely. In the case of Hide My Ass, it may be coming from the server in any one of the 24 nations in which this provider has VPN servers situated.
Is this Illegal?
No. There is nothing illegal about using a VPN server. The idea behind the servers is not to accommodate people who want to conduct activities that are illegal. In fact, the point of these types of servers is to provide anonymity as a shield for people who are worried about having their legitimate security compromised online. This is an increasing concern for many Internet users and has led to many different companies entering this field.
An Example
Imagine that you wanted to visit a server but you weren’t exactly sure whether or not it was safe. For example, you may be worried that there is some sort of identity theft or simply some sort of rather intrusive advertising being conducted on the site and you want to make sure that whoever is running the site doesn’t have access to your IP address. This is one of the reasons that people use VPN servers. Using the servers, your request appears to come from a different IP than your own, which means that there is no way for the person who owns the site to figure out where the request was actually made from first.
As a layer of additional security, the services use protocols such as SSL and PPTP to make sure that nobody can listen in on the traffic with a device such as a packet sniffer. If they were to try, they would simply get a bunch of data that was completely unusable to them without the encryption key, which is not communicated over the connection.
Services such as Hide My Ass are popular with consumers. While VPN networks have been in use for many years, they have been mostly used by businesses that were worried about protecting client information or industry secrets. Today, end-users are finding that the services are excellent ways to make sure that they’re not exposed unduly on the Internet in terms of the information exchange or their identity. There are servers located in so many nations that it’s easy to make it seem as if the traffic is coming from any number of places with the services.
SSL Encryption, Certificates and HTTPS
SSL or Secure Socket Layer is a protocol which must be followed by all technologically conducted transactions to ensure that online activities involving personal information such as credit card details will be kept confidential. Every time a person will input private data in a website perhaps for membership or for paying for purchases, the browser that the person is using will run SSL Certificate verification before submitting or with SSL encryption of data to the website.
HTTPS or Hyper Text Transfer Protocol Secure is what people may only see after this security process shown on the address bar which indicates that the site is secure. To get an HTTPS certificate alone is not nearly enough as SSL Certificates, which are stand along protocols, reinforces these certificates. HTTPS certificate is needed for securing online bank transactions or perhaps any transaction which call for high security because of involvement of money. These are necessary to avoid hackers to view highly confidential data which has been entrusted on numerous websites.
There are various kinds of SSL certificates and can be offered free for some web hosting plans and companies depending on the ecommerce site owner and the site itself. On the other hand, it may also be a shared SSL where websites must only be sub domains of the chosen web host. A shared SSL may also come in the form of shopping cart programs or pages which contain directories that are secure data yet can still be accessed by customers. The third type of SSL certificate is the dedicated SSL which is the most commonly seen for dedicated hosting plans and sites are allowed their own domain names chosen by the customer. An SSL certificate will also differ in the level of SSL encryption strength from 40 bit to 256 bit.
To authenticate one’s SSL certificate, there are three ways. The first is through domain validation where contact information is listed under the website’s domain in the WHOIS database, organizational validation where data regarding the business operating the website including physical and web addresses will be examine and the extended validation that provides the most complete security validation. A sign of the extended validation is the appearance of green text on the address bar.
For the SSL Certificate to be imported and enabled with the Microsoft Exchange has evolved and is generally difficult as it requires every bit of information entered exact. First pull up the Exchange 2007 program and make a request for the Exchange 2007 certificate by using the Certificate Request Generating tool online.
