# SSH agent forwarding
#
# Ensure that SSH-Agent forwarding will work when re-attaching to the tmux
#   session from a different SSH connection (after a dropped connection).
#   This code will run upon tmux create, tmux attach, or config reload.
#
# If there is an SSH_AUTH_SOCK originally defined:
#   1) Remove all SSH related env var names from update-enviroment.
#      Without this, setenv cannot override variables such as SSH_AUTH_SOCK.
#      Verify update-environment with: tmux show-option -g update-environment
#   2) Force-set SSH_AUTH_SOCK to be a known location
#      /tmp/ssh_auth_sock_tmux
#   3) Force-create a link of the first found ssh-agent socket at the known location
