tmux immediately crashes, but not sudo tmux

I have a problem where tmux crashes immediately upon start. But when I run with sudo it works fine.

Output of "strace tmux" here: http://sprunge.us/LXVI

What permissions am I missing?

EDIT: These problems are over an SSH connection.

Re: tmux immediately crashes, but not sudo tmux

I have a feeling that you don't have the ability to write to your own home directory. 

What are the outputs of:
echo $HOME
whoami
ls -l /home
ls -la ~

Re: tmux immediately crashes, but not sudo tmux

I was bored so I looked over your strace pretty closely, and compared it to an strace of my own. Aside from the fact that I have a .tmux.conf, the two were practically identical right up until the end. The only thing I can come up with is maybe your user environment is causing problems. Create a new user (I'd recommend using bash shell if that's what root is using), switch to that user with su, and try running tmux.

Edit: also, code tags pls.

Re: tmux immediately crashes, but not sudo tmux

I took the liberty of adding code tags for you.   That output all looks reasonable.  Let me ponder.

edit: I missed seeing alphaniner's post.  That looks like a reasonable suggestion.

Also, let us know which shell you are using and maybe let us see the files that that shell sources (bashrc, etc...)

Re: tmux immediately crashes, but not sudo tmux

Are you running tmux in a console, or in a terminal emulator in X?

Re: tmux immediately crashes, but not sudo tmux

Creating a new user didn't help. Made sure it had full access to its home directory.

Not sure if it helps but the strace is here: http://sprunge.us/UJdT

Re: tmux immediately crashes, but not sudo tmux

My main user uses zshell and has .zshrc and .zshenv both symlinked to a git repository for syncing between servers.
zshrc: http://sprunge.us/dPXj (note that the tmux alias is only used on OS X)
zshenv: http://sprunge.us/LACh

My new user created by alphaniner's suggestion uses bash, and has shell sources from /etc/skel:

#
# ~/.bash_logout
#

#
# ~/.bash_profile
#

[[ -f ~/.bashrc ]] && . ~/.bashrc

#
# ~/.bashrc
#

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

This is all on a server which I'm accessing over SSH from iTerm on OS X.

Re: tmux immediately crashes, but not sudo tmux

I noticed the SSH vars in the strace, but it didn't dawn on me. That probably factors in to the equation as well.

Re: tmux immediately crashes, but not sudo tmux

I can imagine tmux crashing because of some problem related to SSH. But I can't really see how those problems would not lead to a crash when running as root. That said I don't have physical access to this server so I can't check if these problems are still present when running from the console.

Re: tmux immediately crashes, but not sudo tmux

I should have said "that may factor in to the equation". I don't know SSH well enough to say one way or the other.

IMO though, it should have been mentioned in the OP.

I've now edited the OP to add this.

Re: tmux immediately crashes, but not sudo tmux

Is your problem at all similar to this?

[user@localhost ~]$ tmux
^[[?1;2c
-bash: 1: command not found
                           -bash: 2c: command not found
                                                       [user@localhost ~]$ [user@localhost ~]$

If so then you should follow the thread here and remove the /dev/pts line in /etc/fstab. /dev/pts is now handled by systemd and this line causes problems with everything.

Fixed my problems. Thank you very much. Should have tried searching before posting a new thread.

Re: tmux immediately crashes, but not sudo tmux

Oh I guess I was a bit unclear. What I meant to say was that removing the /dev/pts line in /etc/fstab as per quantumphaze's suggestion worked brilliantly, and that I should have seen the thread from a few days back with exactly the same problem.
