Ubuntu 10.04

[straps]

I'm using Ubuntu Linux 10.04 at work and I'm trying to connect to a customer network via VPN.

I've created a .pcf file that works very well on another machine with Ubuntu 7.10, but with my version it connects, works for a minute or two and then it stops receiving packets anymore.

I've seen in the Cisco client log many rows like theese when it stops communicating

Code: Select all

1719   16:11:12.864  05/11/2010  Sev=Info/6   IKE/0x4300003D
Sending DPD request to 000.000.000.0, our seq# = 3805041683

1720   16:11:17.870  05/11/2010  Sev=Info/4   IKE/0x43000013
SENDING >>> ISAKMP OAK INFO *(HASH, NOTIFY:DPD_REQUEST) to 000.000.000.0

1721   16:11:17.870  05/11/2010  Sev=Info/6   IKE/0x4300003D
Sending DPD request to 000.000.000.0, our seq# = 3805041684

1722   16:11:22.876  05/11/2010  Sev=Info/4   IKE/0x43000013
SENDING >>> ISAKMP OAK INFO *(HASH, NOTIFY:DPD_REQUEST) to 000.000.000.0


Seems that the client does not receive nothing anymore from server...

I've tried anything, from deactivating all type of firewall, to using VPNC without success...

An extract of the pcf

Any suggestion please?

I'm having the same issue, but I don't have the log like you do. Not sure what you used to get it. Here's the link I followed for installation

hi,

Did you ever manage to resolve this? I am experiencing a similar issue.
Running Ubuntu 10.10, kernel 2.6.32-21-generic with patches from:
http://www.shuvoovuhs.com/linux/install ... k-meerkat/

The vpn running perfectly fine for a while. Then when/if it times out it causes all my network processes to hang. I can't ssh, run subversion or anything. The only thing that seems to continue to work is ping.
The only way to resolve the issue is to do a vpnclient disconnect.

best regards
