2015-09-18 Emacs and TTY

I’m connecting to Kallobombus via SSH. It runs Debian 7.9 aka Wheezy. Recently a new problem appeared. I can no longer use Emacs unless I’m root.

alex@kallobombus:~$ emacs
emacs: Could not open file: /dev/tty
alex@kallobombus:~$ sudo emacs
alex@kallobombus:~$ ls -l /dev/tty
crw------- 1 root root 5, 0 Sep 18 08:28 /dev/tty
alex@kallobombus:~$ cat /etc/debian_version 
7.9
alex@kallobombus:~$ which emacs
/usr/bin/emacs

What’s the problem?

On a different server, running Ubuntu 14.04.1 LTS:

kensanata@po6:~$ cat /etc/debian_version 
jessie/sid
kensanata@po6:~$ ls -l /dev/tty
crw-rw-rw- 1 root tty 5, 0 Sep 15 11:42 /dev/tty
kensanata@po6:~$ emacs

So, is the solution to chmod o+rw /dev/tty?

Oh well, I ran sudo chmod go+rw /dev/tty and that seemed to fix the problem. I just hope it didn’t create any security issues.
