connecting through master ssh connection on intermediate host

Suppose host B does not allow public/private key authentication - only secureID authentication. I already have a master ssh connection from host A to host B. Host A does allow public/private key authentication. Is there any way to connect from host C to host B by way of the master ssh connection on host A? In other words, is there any way I can connect to host B from host C without having to enter the secureID passcode? Thanks!

If you don't have a SecurID token, it means you are not supposed to log into anything that can only be accessed using a SecurID token. No one here is going to show you how to hack.

obviously i have a secureID token. i just don't want to have to enter it every time i make a connection. my wireless sucks, so that happens quite often
