I was hoping someone could help me understand what happened with my Ubuntu server.
I had an issue with it acting odd, I won't go into detail but I restarted the server with this command:
shutdown -r now
When it came back up, I attempted to use screen and was given this error:
No more PTYs. Sorry, could not find a PTY. [screen is terminating]
I found this website which told me this:
You have to change /dev/ptmx file permissions:
# ls -l /dev/ptmx crw-r--r-- 1 root root 5, 2 nov 18 23:28 /dev/ptmx # chmod a+w /dev/ptmx # ls -l /dev/ptmx crw-rw-rw- 1 root root 5, 2 nov 18 23:34 /dev/ptmx
This didn't resolve my issue since I was already at:
crw-rw-rw- 1 root root 5, 2 nov 18 23:34 /dev/ptmx
So I found this post:
So, I did what the answer suggested, which was:
# mount devpts /dev/pts -t devpts -o mode=620
And it worked fine.
Anyone know what happened, why, and what the devpts did to fix it? I'm completely lost on this one.
