When I try to start 'screen' or 'byobu', I get the following error message:
$ screen No more PTYs. Sorry, could not find a PTY. [screen is terminating]
I seem to have enough though:
$ ls /dev/pts $ cat /proc/sys/kernel/pty/nr 0 $ cat /proc/sys/kernel/pty/max 4096
Some more info:
$ uname -a Linux cube.mydedi.net 2.6.18-194.8.1.el5.028stab070.5 #1 SMP Fri Sep 17 19:10:36 MSD 2010 x86_64 x86_64 x86_64 GNU/Linux
If you need any more info please comment. This is on a low-end VPS, but it used to work just fine, until it stopped working. Everything else seems to be fine though.
