I've used the ssh-agent from oh-my-zsh to manage my SSH key. So far, so good, i only have to type the passphrase for my private key once when I start my shell and public key authentication works great.
The problem is however that key forwarding doesn't work. There are 2 servers A & B which I can use public key to login. When I ssh into A then from there ssh into B, I must provide my password, which should not be the case.
A is a CentOS 5.6 box, B is an Ubuntu 11.04 box. I have this on my local
Host * ForwardAgent yes
OpenSSH on A is standard openssh 4.3 package provided by CentOS. I also enable
ForwardAgent for ssh client on A, but forwarding still doesn't work.
