ssh fatal: Timeout before authentication

ssh fatal: Timeout before authentication

Server A works: Can accept connections from 10.x.x.x clients and 172.x.x.xclients


Server "B" Can accept connections from 10.x.x.x clients and FAILS on 172.x.x.x clients

Both have been checked for the same software;
openssl A.00.09.07i.005 Secure Network Communications Protocol
HPUXBastille B.3.0.31
sshd_config is the same. (I copied it from working server to non working)
I have compared the services files---same
I have done a stat on the lan cards---same
I have checked the sshd config file---same
I have done a directed traceroute ----same
I have checked the pam.conf (authetication)---same

I have done a DEBUG connection
attached there is a ssh faild and a ssh success log file.

If I add the incoming address to server B ssh is successful.
All the hosts file, resolv file, nswitch file are the same.
These systems are trusted and have bastille on them.


It seems like a DNS issue. I cannot add all the clients to the hosts file, too many.

I am at a loss!

Thanks

Hi,
can you ping 10.x.x.x and 172.x.x.x from both Server A & B?


Thanks & Regards

It was a DNS server issue. No entry for the server. Thanks
