Unable to open pty: No such file or directory

Unable to access the VPS via SSH? Are you getting the following error?

# vzctl enter 1022
enter into VE 1022 failed
Unable to open pty: No such file or directory

Fix:

# vzctl exec 1022 /sbin/MAKEDEV pty
# vzctl exec 1022 /sbin/MAKEDEV tty
# vzctl enter 1022

To Fix this issue permanently,

1. Edit the file /etc/rc.sysinit of the VPS server (Here VEID of the VPS server is 1022)

2. Comment the line
#/sbin/start_udev

3. Add the following lines after /sbin/start_udev:

/sbin/MAKEDEV tty
/sbin/MAKEDEV pty

4. Reboot your VPS
vzctl restart 1022

Note: Do ensure that this is checked when you run yum/up2date on server.
