Pty allocation request failed on channel 0

[ravirajukrishna]

The image attached shows two scenarios one in which ssh access to hypervisor is granted another which says

PTY allocation request failed on channel 0

shell request failed on channel 0

When i reboot the hypervisor server,things work fine.But some point of time i again face the same issue.How to go about it

I tried using ssh -T option to login ,which allowed me to login but it did not give me # prompt .

Any replies please do send me to ravirajuk.raju@gmail.com

Hi, I had exactly the same problem. Have you found a solution ? Reboot fix the problem but some times after reboot I get again the error.

Thanks in advance.

This happen when the directory for pty is not created under /dev/pty

It was fixed like this.

mkdir /dev/pts
mount /dev/pts

Also refer the below link for more info and idea on it.
