Public bug reported:
Binary package hint: vpnc
Upgrading from Feisty to Gutsy has broken my Cisco VPN, but I'm not sure
how to diagnose it.
Under Feisty, I could use either the command line "sudo vpnc" or use
NetworkManager to connect to my company's network, and it worked fine.
Apparently there's also an "official" Cisco client, but you need a
kernel compiled before the fall of the Berlin Wall to make it work (ie
RedHat).
When I say "the VPN worked fine", I mean:
-Requests to the corporate network were routed OK. I could:
VNC to a desktop at work
SMB onto a drive at work etc
-Requests to my local network were unaffected, I could still:
see my router's webface
SMB to my housemate's Windows box
-Requests for internet traffic were unaffected, I could
receive web-pages via my home internet connection
use messenger programs etc
Under Gutsy, the VPN appears to connect fine (it does not disconnect
immediately, this is *not* a duplicate of 124238). However, nothing at
all is accessible, neither the corporate network, nor the internet.
Without the VPN, NetworkManager (which I'm using for wireless roaming) creates
a file that simply says:
search myHomeDomain
nameserver 192.168.2.1 (myHomeRouter)
That works fine, because the default route just goes straight to the router
which gets name resolution etc from my ISP.
With the VPN connected however, I get a resolv.conf like this:
search myHomeDomain myCorporateDomain
nameserver corporateDNS1
nameserver corporateDNS2
This is useless, as I no longer can see the internet! So, I manually add
"nameserver 192.168.2.1", and that works as a quick fix, but I didn't need to
do that under Feisty - regression.
More importantly, the VPN doesn't work - despite the routing table being
populated with a load of corporate internal IP addresses, I can't
actually see any of them. They don't reply to pings, I can't SMB
anything, yet the connection is alive, I see tun0 under ifconfig.
What information do I need to diagnose the problem?
Why did this work before, and not now?
BTW, before you ask,
"Why did he upgrade to an unstable release on a box needed for work?"
Because Evolution in Feisty is fundamentally broken - useless for accessing
Exchange server. The latest Evolution is a *little* better (though still
essentially useless for doing real work), but is not backported to Feisty.
Doing a partial upgrade to Gutsy to get newer Evolution broke everything
(Nautilus etc.) so I did a full dist-upgrade. Also it seemed an easier way to
move from Beryl to CompizFusion.
Help!!
