I just started to work on Git. I use windows 7 and has installed msysgit(1.7.8) and Tortoisegit(1.7.6). The repository is created on Linux server which is accessible thru LA
One way to do this is
plink works natively with peagent to retrieve the loaded key.
you can find plink.exe along with peagent and other goodies in standard putty distribution
to use it go to:
TortoiseGit Settings -> Network -> SSH client .
by default this contains path to TortoisePlink.exe, instead of that give path to plink.exe
Alternatively you can use ssh(.exe) in msys(git) distribution but then you cannot use private key in .ppk format/Peagent combination. You either need to export your key to OpenSSH format via PuttyGen or create a keypair using ssh-keygen instead.
