On windows I mostly use Putty as my SSH client. But in some cases for example when I use unison or rsync I use the ssh client from cygwin.
Following good practice I use public key authentication and Putty's Pageant to manage my password protected keys. This works great with Putty and Plink. I thought this would be great if I could use the same agent for cygwin too. As often the solution already existed in the form of ssh-pageant.
Here is a small tutorial how to set it up:
- Download the prebuilt version of ssh-pageant from github (direct link).
- Upack it and copy the ssh-pageant.exe to your cygwin's /usr/local/bin directory
- You need to edit your .bash_profile file in order to start the ssh-pageant on opening a shell
The method I use is different form the one described in ssh-pageant's readme as it only starts one instance of ssh-pageant and reuses this in subsequent sessions. It is based on the Github Help about ssh keys.
Update: In never versions the --reuse
makes things a lot easier. (Thanks sun for pointing this out)
Add this at the end of your .bashrc
# ssh-pageant # Cygwin maps /tmp to c:\cygwin\tmp # MinGW maps /tmp to %TEMP% (%LocalAppData%\Temp) # Both consume $TEMP (user-specific) from the Windows environment though. eval $(/usr/local/bin/ssh-pageant -ra $TEMP/.ssh-pageant)
Now you should be able to login using cygwin's ssh.exe with the same comfort of putty.
