SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

well as you said, it's very likely to be a DNS issue. on the destination server run "host ip.of.cli.ent" and that's what sshd is also doing when you connect. you can turn off dns resolution in your /etc/ssh/sshd_config or make it resolve to a valid host name however you see fit.
If you're going between proper Linux systems, why bother? What would this give you other than preshared keys and a while [ 1 ] loop??
It would give you a perpetual ssh session that does not require user intervention. autossh monitors the connection and automatically reconnect if the remote sshd or local ssh client die for any reason.
I thought this was exactly what you asked for originally.
When I ssh into my new Debian box there is a wait of some 15 seconds before the password prompt comes up.
This is a minor irritation, but is a bit annoying, because quite often I go to some other task and when I come back the ssh session has reset and I have to start over.
Original question (above) has to do with having to enter a password to reconnect via ssh, no? OP does not explain why the ssh is "reset" and that would require a different approach to correct, but, regardless, whatever the reason ssh dies, autossh will reestablish the connection automatically w/o the need to login again.
It "fixes" the original issue.
No, the issue is the delay. that's the point. nothing about passwords, nothing about losing connection even really. whether the delay is followed by a password or a direct login, the delay is still going to be there. autossh doesn't fix the issue it hacks around it.
I guess we beat this password vs reconnect thing to death, acid_kewpie?
Two problems, I suppose -- (1) annoying delay for password prompt and (2) having to login again after ssh connection dies (irritating in itself but specially so because of the long password delay).
cov seems to be happy with a solution for problem (1) -- see post #4.
My suggestion deals with problem (2).
So in the end, no delays to login, no need to reconnect and everybody is happy.
