The trick to using screen and an ssh agent is to reset the environment
variables that point to your ssh connection. Here is a script I use to
store the connection information in a file that is sourced by my shell if
it can't find my agent, and the "ss" alias I use to rejoin my session from
another location. I found this somewhere on the web and modified it.
~ % grep ssh-env .zaliases
alias -- ss='~/bin/ssh-env && screen -d -R'
~ % cat bin/ssh-env
#!/bin/sh
SSHVARS="SSH_CLIENT SSH_TTY SSH_AUTH_SOCK SSH_CONNECTION DISPLAY"
for x in ${SSHVARS} ; do
echo "export $x=\"$(eval echo \$$x)\""
done 1>$HOME/.ssh/env
~ % grep .ssh/env .zshenv
ssh-add -l >/dev/null 2>&1 || { [[ -r ~/.ssh/env ]] && source ~/.ssh/env }
