Linux – ssh can’t connect using hostname

bindhostnamelinuxsshubuntu-10.04

I'm setting up some server but I stubbled into an issue with one server.

I setup a local dns server, and when I try to connect to this server with ssh alpha@alpha.stvns.com I will get : Permission denied (publickey,keyboard-interactive).

But when I access it like alpha@192.168.1.2 it works fine with Pubkey Auth.
Strange part is when I connect to a server git.stvns.com => a hostname managed by the dns server, it will connect fine when using the hostname.

I'm using a ubuntu 10.04 amd64 as base for all the server, they are actually identical images I took a snapshot from the bare minimum setup, so can't blame the OS.

I compared my sshd_config files but they are almost Identical, only the place of the authorized_keys is different, can't blame that full for giving problems.

Locally I removed my known_hosts related to the dns server and tried again without any luck.

This is a copy of my sshd_config file maybe someone spots a error:

run

ping git.stvns.com

Are you see 192.168.1.2 ip?

I think you havenot problem with ssh, you have problem with dns.

What dns server are you use? (cat /etc/resolv.conf )
