Re: [opensuse] ssh problem in opensuse 11.1 ADDON
Not sure if you got my reply, I didn't see it show on the list, so here it is again:
Is the machine that you are trying to reach (ssh to) on you local LAN or on the remote network that you VPN to?
- James
Thank you, James. I am not sure since I don't know the definitions of local LAN and remote network in this context. I am trying to reach (ssh to) a computer that belongs to the network I am connected to through the VPN channel. So I guess the answer is remote network. Anyway the same vpnclient in openSUSE 10.3 works perfectly on the same computer. And If I remember correctly it works on another openSUSE 11.1 box as well, though I have to check it again. Could it be a configuration or maybe a hardware/kernel-version (network card) issue?

Yes, the VPN is a remote network.
Could it be a configuration
Most likely.
or maybe a hardware/kernel-version (network card) issue?
No, that's unlikely. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

After connecting by cisco vpn client, try to change MTU size of your VPN interface: sudo ifconfig cipsec0 mtu 1200 or sudo ifconfig cipsec0 mtu 1000 if possible, try to using kvpnc with vpnc -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Finally I could acces the computer I have this problem with. I can open the vpn channel starting vpnclient (cisco's) ifconfig gives: cipsec0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx inet addr:xx.x.x.x Mask:255.0.0.0 inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/64 Scope:Link UP RUNNING NOARP MTU:1356 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:222 (222.0 b) ssh hangs/does not respond. I have changed MTU - as you suggested - to 1000 and 1200. This change was reflected in the cipsec0 part of ifconfig info. Still no ssh response. I can use vpnc - command like - but I would prefer vpnclient. It works in previous opensuse versions perfectly -so it can not be a not supported hardware issue. When I set the network I did it the same way is in openSUSE 10.3. I guess this is an openSUSE 11.1 issue. Any other idea how to fix this?

Hello Istvan, How about sharing the output of ssh -vvv <DESTINATION>, where destination will be the IP or host name of the computer you are trying to reach. The -vvv will provide very verbose output. I have used the Cisco VPN product on OpenSuse since 10.3 and have no issues running it on 11.0 and 11.1.

Thanks James. I will send the requested information as soon as I can access the affected computer again. Istvan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hello: Now I could acces the problematic computer. ssh -vvv gives this: ~> ssh -vvv -l lxuser 10.10.3.66 OpenSSH_5.1p1, OpenSSL 0.9.8h 28 May 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.10.3.86 [10.10.3.86] port 22. Here it hangs. Does this help? Thanks, Istvan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
