Re: allow ssh on particular port....

Hello,

Please mention the OS which you are working. Inn HP-UX this is
possible. SSH 4.2
version is supporting this. Auth selection patch is used to support
this. The following server config directives are used to support this..

# Auth selection
#
#HostbasedAuthAllowUsers
#HostbasedAuthDenyUsers
#PubkeyAuthAllowUsers
#PubkeyAuthDenyUsers
#KerberosAuthAllowUsers
#KerberosAuthDenyUsers
#KerberosOrLocalPasswdAllowUsers
#KerberosOrLocalPasswdDenyUsers
#PasswordAuthAllowUsers
#PasswordAuthDenyUsers
#ChallRespAuthAllowUsers [pam] user1 user2 ...
#ChallRespAuthDenyUsers [pam] user1 user2 ...
#ChallRespAuthAllowUsers [bsdauth] user1 user2 ...
#ChallRespAuthDenyUsers [bsdauth] user1 user2 ...
#ChallRespAuthAllowUsers [skey] user1 user2 ...
#ChallRespAuthDenyUsers [skey] user1 user2 ...
#ChallRespAuthAllowUsers [securid] user1 user2 ...
#ChallRespAuthDenyUsers [securid] user1 user2 ...
#GSSAPIAuthAllowUsers
#GSSAPIAuthDenyUsers

So using this directives u can deny or allow specific users in specific
ports and specific authenitcation.

Thanks,
Santhi.

Hi team ,
I am running ssh on two ports.
port 22
port 75 in sshd_config
now i want to allow root user in port no 25 and deny in 22.
guys if anybody knows let me know.

I assume you meant port no 75 not 25.
I know of no way. But the common opinion is that it is a bad idea anyway.
Log in as a user and then su to root when logged on, instead of trying to
log on directly.
