Ranked in these QuestionsQuestion Ranking
Pro De facto standard client for SSH, Telnet and Rlogin
Pro Source code available
Full source available. Compile and modify it yourself.
Pro Transforms cmd.exe into something bearable
Cmd.exe is still irreplaceable for many tasks on Windows. This makes the experience less painful.
Pro Can easily search in history
The user can search in history by simply pressing Ctrl+R.
Con Tedious logging/tracing
Its tedious to set up logging and tracing (e.g. for serial connections).
Con Lacks features
It is JUST an SSH client. There are many other options with built in X-servers, Multitabbing etc.
Con Can not save passwords
Anyway, you can use "PuTTYgen" to generate a key pair, then use "Pageant" to do a password-less SSH remote login.
Con No global settings
If you want to change a setting for all your connections, you'd have to do it individually.
Con No login scripting
Con Supports cmd.exe not the successor platform
It's for cmd.exe which was abandoned by Microsoft in the favor of PowerShell. Using PowerShell is more effective than cmd.exe even with CLink, unfortunatelly.
