Causes:
This could be caused by a corrupted /dev/null file.
Or
Other SSHD daemons handles the SSH and routed the default sshd process to /dev/null
Ex: dropbear
To fix the error remove /dev/null
# rm -rf /dev/null
Then create that node using the following command
# mknod /dev/null c 1 3
Then restart the sshd service
#/etc/init.d/sshd restart
