==== launch automatically over SSH ====

if [ -z "$TMUX" ] && [ -n "$SSH_TTY" ]; then
    tmux attach-session -t ssh || tmux new-session -s ssh
    exit

===== troubleshooting =====
==== open terminal failed: missing or unsuitable terminal: xterm-256color ====
Your system doesn't have xterm-256color. You could:
<code bash>export TERM=xterm</code>

Maybe the file ''/usr/share/terminfo/x/xterm-256color'' is corrupted. It may be fixed upon (system/package) upgrade / reinstall.

Meanwhile you can use other terminfo entry. You can get the available options by ''ls /usr/share/terminfo/x''.

<code bash>ln -sf /usr/share/terminfo/x/xterm-color /usr/share/terminfo/x/xterm-256color</code>
