Here is the trace when I try to Install :

Solved insmod CiscoVPN module problem

Hi, I understand the problem on my FC4
I installed the kernel package arch i686 and the kernel-devel arch i586.

Solution:

I yum remove the i586 kernel-devel and I download from download.fedora.redhat.com/pub/fedora/linux/core/updates/4/i386/
the i686 one.
I installed it and I can setup and insmod the CiscoVPN module successfully.

I hope this information can help.

bye bye Arm74

Freeze under different Conditions

Hello friends,

I too am using the Cisco VPN Client 4.8.00 (0490). My kernel is 2.6.15.1. I was able to compile the client without any issues. The client connects without any issue. The problem that I am facing is of a different kind.


My internet access is through a CDMA phone. The machine connects to the phone using COM1 port. Now if the phone is powered off or if I yank out the cable when the VPN is connected the machine freezes. The last messages recored by syslog are

Mar 20 09:03:01 pppd[3920]: Hangup (SIGHUP)
Mar 20 09:03:01 pppd[3920]: Modem hangup
Mar 20 09:03:01 pppd[3920]: Connection terminated.
Mar 20 09:03:01 pppd[3920]: Connect time 1.0 minutes.
Mar 20 09:03:01 pppd[3920]: Sent 3413 bytes, received 1508 bytes.
Mar 20 09:03:02 pppd[3920]: Connect time 1.0 minutes.
Mar 20 09:03:02 pppd[3920]: Sent 3413 bytes, received 1508 bytes.
Mar 20 09:03:02 pppd[3920]: Exit.


After this the system hangs. If I try the same with the ethernet port and say yank out the ethernet cable. My system does not freeze.

Any pointers towards solving this issue would be really appreciated.

Warm Regards
Kaushik

Hi Kaushik / kmamania:

Unfortunately, I don't know a solution for your problem with the Cisco VPN Client. However, you could try to use vpnc for your VPN connection and look if this solves the problem.

Hey thanks for the advice. I managed to solve the issue in a different manner. There is a script called ip-down in /etc/ppp. This script gets called each time the ppp interface goes down. Since there was a 400ms gap before the machine froze. Explicitly disconnecting the VPN worked for me.

But now the problem is that if i try reconnecting my vpnclient it fails for a few attempts.

There is another issue where i would appreciate some help...
the Cisco Client installs itself in /etc/CiscoSystemsVPNClient. Now my root partition is a read-only partition and I plan to keep it that way. Those files which need to be written too (eg. the profile files) can be placed in a diff partition with a sym link. But this does not work..

Has anyone tried a different location for the Profile and ini files other than the standard locations.

Warm Regards,
kmamania

Unfortunately, the vpn client gets confused like that. It also happens 99% of the time when resuming from a suspend. My workaround for it is to restart vpn:

# /etc/rc2.d/S85vpnclient_init reload


Doubly unfortunately, Cisco does not like setting the suid bit on vpnclient, which vpnclient_init calls. I wrote a small .c that I gave suid on that just calls vpnclient_init. No go. It looks like Cisco is programmatically looking for suid, and not liking it. For reasons unknown...
