fatal daemon() failed: no such device

Exact error message:  nov 12 14:34:09   <hostname>  sshd2[15154]: fatal daemon() failed: no such device 



Steps to fix the error:

1.Remove /dev/null directory

   #rm -f /dev/null

3.Then start the sshd service


 # /etc/init.d/sshd start


 # /etc/init.d/sshd status



It will resolves the issue.
