Hi

Firstly, thanks for the code.

I'm using it on CentOS5.5 with AMD Opteron 2212HE (4 core, 2x2)

I'd read that there were problems with the client on multprocessor architectures. And I did see the box hang after random intervals after the client had started and connected.

I therefore used affinity to keep the processes locked to a single core, but that has not had the desired effect either.

Idon't get any debug messages either, the box just hangs. Any ideas ?

I am using vpnclient-linux-x86_64-4.8.02.0030-k9-AMD64_ONLY_by_t3x.tar.gz

Hi flare,

generally speaking, Opteron should work fine. We use a 2xquadcore opteron on our ESX and we have no problem with our virtual VPN boxes which runs Slackware linux & vanilla kernel to keep VPN up and we never had an hangup. I cannot state if it depends on the fact that they run on a VMWARE virtual machine or because we used a vanilla source tree for the kernel, but again, we had no problem up to now.

If the box hangs in the way you describe, it's something kernel-related IMHO.

cheers,

Hi,

It took a while, but we built a vanilla version of the kernel 2.6.35 and applied the patch from http://www.lamnk.com/blog/vpn/how-to-in ... la-64-bit/

It sill crashes, this is using centos5 as the original OS.

Thanks

Hi flare,
it's difficult to try to understand where's the problem without analysing your system and the execution of the code.

I have few time at the moment, write me at my email with more details and' i'll try to have a look at it.

cheers,

Here's the report from another user (Mario):

Hi,
Thank you for making your binaries available. The straight forward
installation failed for my system. I had a modified installation of
vpnclient-linux-x86_64-4.8.02.0030-k9, patched to work with my kernel,
which compiles and runs well on Intel but fails on AMD. As a workaround,
I dropped the binaries and lib file as indicated in the readme file, and
that worked.
