Hello, tmux experts. I'm having an odd problem.
Could you help me determine if it is a known issue or a new issue? If a new
issue, how would I go about raising a bug report ?
I am running tmux on a line card in a multi-chassis router.
The following sequence works as expected:
1. Attach to the node via a terminal server to the node's serial port
2. rlogin to the line card
3. Start the tmux server and attach the session:
tmux new-session -d -s ha-wbt
tmux new-window -t ha-wbt:1
tmux attach-session -t ha-wbt
4. Disconnect via <Ctrl><B> d
5. Log off the line card
6. At a later time, rlogin to the line card
7. Reattach to the session
tmux attach-session -t ha-wbt
However, whenever I connect to the node via telnet instead of via the terminal
server and serial port, any attempt to run the "attach-session" command causes
the server to crash.
I'm using the following packages:
tmux-1.7
libevent-2.0.21-stable
ncurses-5.6
Line card is running Montavista Linux:

Linux lc3 2.6.99.99 #1 SMP Tue Mar 5 15:26:06 PST 2013 ppc unknown
