[opensuse] Problem with tmux: it says there are no sessions, which is false.
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi. On machine A, I run in an xterm: tmux new and I get the expected response in the terminal. On that machine, on another terminal, I run "tmux attach", and it attaches correctly to the first terminal. Green status line at the bottom. All as I expected. On a second machine, B, I first ssh to the A machine (same user name and UID).

On machine A, I run in an xterm:
tmux new
and I get the expected response in the terminal.
On that machine, on another terminal, I run "tmux attach", and it attaches correctly to the first terminal. Green status line at the bottom. All as I expected.
On a second machine, B, I first ssh to the A machine (same user name and UID). Then I try to attach to the tmux session, and it says no:

I did more testing. It is very strange. A: desktop B: laptop C: laptop 32 bits. 'A' runs tmux. 'B' ssh to it, attach fails. 'A' runs tmux. 'C' ssh to it, attach fails. Local attach in 'A' works. 'C' runs tmux. 'A' ssh to it, attach works. 'C' runs tmux. 'B' ssh to it, attach works. 'B' runs tmux. 'A' ssh to it, attach works. 'B' runs tmux. 'C' ssh to it, attach works. cer@minas-tirith:~> tmux -V tmux 1.9a But: 'A' runs tmux, as root. 'B' ssh to it, works. 'A' runs tmux, as normal user, but in console, not xterm. 'B' ssh to it, works. 'A' runs tmux, as different normal user, in xterm running on XFCE of normal user. 'B' ssh to it, works. So, it only fails running tmux in graphical mode of my normal user, on the desktop machine. It must be something injected by XFCE environment. Furthermore. On the desktop, with 'tmux new' running on the text console, local 'tmux attach' on an xterm fails. Very strange...

I would expect you know how to use grep :) /etc/X11/xdm/Xsession:: ${TMPDIR=/tmp} /etc/X11/xdm/Xsession:export OPENWINHOME TMPDIR /etc/X11/xdm/Xsession: "${TMPDIR:-/tmp}/xerr-${USER}-${DISPLAY}" But no TMPDIR should really mean /tmp by default.

Well ... arguably Xseesion has no business setting TMPDIR either. At least exporting it. TMPDIR should be set by user and then it is user responsibility to ensure it is set consistently. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Of course I do, but I wouldn't know what to grep for and where :-)

Done. There is no appearance of the word "tmp" or "tmpdir" anywhere in the trace. I see this: socket(PF_LOCAL, SOCK_STREAM, 0) = 5 connect(5, {sa_family=AF_LOCAL, sun_path="/run/tmux/1000/default"}, 24) = -1 ECONNREFUSED (Connection refused) close(5) = 0 open("/run/tmux/1000/default.lock", O_WRONLY|O_CREAT, 0600) = 5 fcntl(5, F_SETLK, {type=F_WRLCK, whence=SEEK_CUR, start=0, len=0}) = 0 unlink("/run/tmux/1000/default") = 0 socketpair(PF_LOCAL, SOCK_STREAM, 0, [6, 7]) = 0 The full trace is here: http://susepaste.org/26498787

Both laptop (client) and desktop (server) have TMPDIR set to /tmp (and not my doing). But when I ssh from laptop to desktop, the variable is unset (and not by me, either - at least to my knowledge). Running: TMPDIR=/tmp tmux attach runs just fine. So at least I have a workaround... - -- Cheers / Saludos, Carlos E. R.
