agent forwarding

[micsuka]

first of all, tergent just works well for me, I use it with automatic key locking, thanks for it.

However, when I try to use agent forwarding with ssh -A ... from termux, it does not work. I couldn't find any pointer about this.
Sometimes it's needed to do an ssh from the server where I sshed. :)

thanks

This seems to work, if use ssh-add:

• Make sure that ssh-agent is running.

  ssh-agent > agent.env
  . agent_env
  

• Add the key

  ssh-add -s $PREFIX/lib/libtergent.so
  

  It asked me for a PIN, but just the empty prompt was sufficient. Not sure if there is a way to avoid this.

• Now

  ssh-add -l
  

  should list this key.

• You can now use ssh -A, and continue on the other server, and it will require your fingerprint!

  You do not have to pass -I $PREFIX/lib/libtergent.so to ssh at this point.

These steps have to be repeated in a new session, but can probably be put in some startup script, maybe based on https://www.reddit.com/r/termux/comments/10bqclm/comment/j4kk377/?utm_source=reddit&utm_medium=web2x&context=3.
