Disabling SSH protocol version 1

by Nish Vamadevan · Jan 26, 2014 · 1 min read

When Changing on Version 1 on Debian, have thrown the following error and generating the key did not fix the issue.

sshd: no hostkeys available -- exiting.

Make sure you have the Version 1 & 2 Hostkeys are commented out like the following.

HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key

Remove And Install openssh-server via apt-get seem to have fixed the issue.

I have checked the permission issues, it seems to be some kind of issue caused this error which I did not find the root cause of this problem.
