I'm on Ubuntu 12.04. When I try to connect to our server
ssh user@server -p 1234 -i ~/path/to/my/private-key
it asks me 3 times for the private key's passphrase and finally fails, though I always enter the correct one. When I try it with Putty (converted the OpenSSH key to
.ppk) it works without any problem. What could be the reason?
