Hi,
We got a error message when trying to logon to a virtual Centos with ssh (putty). Every thing runs in Proxmox (OpenVZ).

The error message is: "No value for $TERM and no -T specified"

I have tried to set $TERM in /etc/bashrc and ~/.bashrc but with no succes. I have also tried to export the evironment från putty.

In the begining the virtual machine worked as it should but for some reason not any more. The machine runs but not the root session.

So you can't login as root remotely is this right? Can you use "sudo" when logged in as a user which can remotely login?

What did happen that the server refuses remote login as root? Means did you install or did you configure something?

Are there any further error messages? (e.g. in "/var/log/messages" or "/var/log/syslog" or "/var/log/auth.log")

What do you see in "/dev" directory?
What does the command "mount" output?
Is udev running? ("ps aux | grep udev")

This what I found (doesn't look good):
/var/log/secure:

Thanks very much!

The link you sent me was easy to follow and fixed all my problems!

I did this:
1. Edit the file /etc/rc.sysinit of the VPS server

2. Comment the line
#/sbin/start_udev

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

/sbin/MAKEDEV tty
/sbin/MAKEDEV pty

Then a reboot of the VPS.
