[opensuse] vpnc problem - loosing local network after successful remote login
I'm having a very annoying problem with VPNC in openSUSE10.2. rpm -q vpnc returns vpnc 0.3.3-34 I can connect to the remote vpn server (giving my preshared key, user id and password) . The connection appears to be successful, but then I immediately loose all network connectivity on the local machine. I cannot ping anything external or even my local router. To recover my network connectivity, I have to kill the vpnc session and then cycle the network card down and back up again. Nothing else seems to restore my network connectivity. Any tips or ideas on how to resolve this one? C -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I still have the same behavior with vpnc. I can connect to the remote server, but as soon as the connection is authenticated and I am connected, my local NIC looses all connectivity to the internet... it's like someone hits the off switch on the network card. I can only wake it back up by cycling the card down and back up again... which then drops my vpn connection to the remote server. Does anyone have any ideas on this?

Perhaps, isn't it this? https://bugzilla.novell.com/show_bug.cgi?id=134480 Regards, eshsf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Possibly.... not 100% sure. I was tinkering with it again last night. I was able to connect, and this time I left the connection open... after a rather long time my network connection came back. I had limited connectivity... very limited, but it was working, and ALL network traffic was being routed through the VPN connection. That's the next thing I need to look into... I need/want to route only some network traffic through the VPN connection, and the rest via my own ISP. I have no idea though why after negotiating a connection that it takes several minutes for the NIC to return to an "alive" state....

I don't think that's possible, because VPN is a tunneling protocol. One of the downsides of using it to contact machines in my office, for example, is that if I do any web browsing or check personal email while I'm connected, it all runs through our network at work. So I connect, check my email or whatever, then disconnect.

No idea either.

Makes me appreciate SSH all the more :-) Can't use SSH though.. only VPN. This is my first serious adventure into VPN... I'm running a LOT of extra services on my home computer... a web server, MythTV (with web access), VoIP clients etc, and I DEFINITELY do not want to route that traffic through the VPN tunnel. Am I "safe" to assume that root level processes (or processes belonging to different sessions and users) that are using the network are not rerouted through the VPN tunnel once it's opened? If this is the case... a solution would be to just start up a second session (same or different user) and do my work related stuff (via the VPN) in that session and leave my regular session up and running in a different terminal.

That's not how networking works without custom routing statements. I think the Cisco VPN server and clients could be setup that way but it's been almost three years since I had to play with them that I don't remember. Leave your default route as it is without the VPN connection, after you connect, and see if you can still see traffic from the VPN side. One thing I can tell you is to make sure your home network address space is different from the VPN network or you will definitely have problems with routing. Correct routing rules will be the trick if it works. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
