CENTOS 5.7 "there are no more ptys" Using screen on Non-Root User - d3spis3m3 - 01-23-2012 10:49 AM
Error using screen on Non-Root User for some reason. only by using sudo or root account can you run screen. I searched and searched and all the "fixes" said it was a permission error on /dev/ptmx Which was part of it but there was more to it.
Here is the fix
PHP Code:
chmod 666 /dev/ptmx;
chmod u=rwxs,g=rx,o=rx /usr/libexec/pt_chown;
chown root:root /usr/libexec/pt_chown;

Sorry, but you can't use sudo or root on CentOS. You use Su.
Looks like you have a Debian based OS, might be your problem.

I've installed and used sudo on CentOS:
Code:
yum -y install sudoMaybe a update and reinstall would work:
Code:
yum -y remove sudo
yum update
yum -y install sudoRE: CENTOS 5.7 "there are no more ptys" Using screen on Non-Root User - f8ll - 01-24-2012 05:49 AM

I've had this problem before. It's actually a problem on the host node mounting devpts. You should be contacting your provider and informing them of this problem. What you suggested does work and is a quick fix if you need it working right away.

CentOS is pretty much the only major disto that doesn't include sudo by default for some reason. Using sudo can be more secure than logging in as root.

hmm, you are actually right.
http://wiki.debian.org/sudo
Looks like sudo is installed with the Desktop task in squeeze.

Most graphical application specially administration utilities requires sudo to gain root access and apply configuration changes.

Ok, I was posting it if anyone else had problems with it. Why am I getting all these contradictions. If it worked for you right off the bat great. If this can't help you because you are "all almighty h4x0r king" then STFU and GTFO
