SOURCE: SecureCRT - Version 6.2.2 (build

This log shows you are connecting to a Cisco router running SSH protocol version 1, but you have set your SecureCRT to require using SSH version 2.

You either need to either

Set the SecureCRT software to allow connections using SSH version 1

or

upgrade your Cisco device to support SSH version 2.

Unable to load client protocol


b> Internet Protocol, also known as IP, is a communication protocol which heavily uses the TCP/IP standards for packet switch internetworking. IP manages addressing methods for data encapsulation and delivery. IP was developed by the United States Department of Defense and is now widely used by the public. IP Version 4 is the fourth version of Internet Protocol and the first one to be deployed to the public. Updating and installing Internet Protocols are important to the integrity and reliability of your Internet connections.

Click the "Start" button at the bottom of your desktop screen. Click on "All Programs." Select "Run" from the Accessories folder. Type "CMD" in the run dialog box. The command prompt window will appear. Type "Netsh Interface ipv4 install" on the command prompt line. Press "Enter." Restart your computer.

Unknown connection protocol for default or autosession


Assuming you can get past that error message:
  • go to the Options menu, then Global Options
  • Click on the + to the left of Options to open the item
  • Click on Default Session
  • Uncheck the box "Use auto session
  • Click on OK
If you can't get past that message, uninstall SecureCRT and re-install it - it sounds as though some of it's configuration data has got corrupted. If you are comfortable doing this, use Windows Explorer, make hidden files & folders visible and then go to
C:\Documents and settings\your-user-name.

For all the following, ensure SecureCT is not running - even in the System Tray.

Look for the SecuerCRT folder in Application Data and Local Settings\Application Data (I can't remember which one it's in offhand). In that folder, there's a folder called Config. Assuming that you don't have a load of connections set up that you don't want to lose, delete the whole folder. SecureCRT will ask you where to re-create it next time it starts.
It's also possible to delete do it this way:
  • in the Config folder, edit global.ini with notepad.
  • Find the line that starts "S:"Auto Session Name"="
  • Delete the whole line
  • Save and close the file
  • Restart SecureCRT

A website that explins www3. protocol


Hello,

The protocol is actually the portion of the URL before the www - in your case the http:// which indicates that the page you are trying to access can be accessed using the hypertext transfer protocol. Other protocols include FTP (file transfer protocol), or https:// which is Hypertext Transfer Protocol over Secure Socket Layers.

The www portion of the website can be controled by the site operator - in your case the operator may have used ww2 or ww3 to load balance traffic or to divide up different sections or versions of the website.

Hope that helps!
