All,
Has anyone had issues with 13.2 having poor SSH Tunnel reliability?
=== details === I have used AutoSSH to connect to my cloud server from various computers behind firewalls to provide a VPN like connection to various computers behind firewalls. I'm using SSH tunnels.
The concept is to use SSH to make an outbound connection to the gateway server and establish the tunnel there.
The VPN destinations include Linux and Windows boxes at various points in time.
(I blogged the setup details for a Windows destination here: https://lizards.opensuse.org/author/gregfreemyer/)
The gateway server has been an openSUSE server the whole time.
I've had very good reliability, until 9 days ago when I upgraded the server from openSUSE 13.1 to openSUSE 13.2
Now I am getting failure to connect issues repeatedly. Luckily all 4 of my current "targets" are behind the same firewall, so if I can get to one I can move around internally. That works, but its annoying, and further the "working" connection isn't consistent so one of these days I assume none will work (And I will have to actually go to my office!)
Thanks Greg -- Greg Freemyer www.IntelligentAvatar.net
Not seeing any problem with 13.2 as an ssh target. If I understand correctly your machines (behind a firewall) are using autossh to create a connection to a 13.2 machine so that you can connect back to them without having to leave any ports open on the firewall. All of these connections will appear on the 13.2 machine as having come from a single IP, the address of their firewall. Presumably each will open a tunnel to 13.2 on a different port. Presumably each will refresh the connection as necessary. I assume Each has its public key in 13.2's authorized keys as before. Possible Gotchas: Is there a firewall on 13.2 acting to rate limit these connections, which might all arrive vary close together in time? Is 13.2 going into sleep mode at any time and powering down the nic? -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
