VPN client for linux without compiling kernel Rocco 03-22-2005

Hi,

I'm looking for a VPN client for linux which doesn't need compiling a
new kernel.

We have to equip a large number of notebooks with it and the
installation should be done by the users, cause it would be too hard
getting all notebooks here.
So it has to be quite simple, maybe by runnning a shell script
provided by us to the users.

We use IPSec, L2TP and X509 Certificates.

All I found is a client from Cisco, but it requires Cisco-Apliances
that we don't have...

Any ideas?

Greetings,
Rocco

OpenVPN is a nice user-space implementation and at a first glance
exactly what I need, but it uses SSL and is not compatible with IPSec
and L2TP.

Maybe this is the price to pay to get a pure user-space implementation...

Is that really important? Are particular buzzwords important of is
security the issue?

With OpenVPN It's only necessary for one end to have a highport
through the firewall... and you can decide which one.

Static (private) keys mean that somebody has to break into one of
the machines to gain entry. If the machines are behind a firewall
that forwards only the relevant highport, unauthorised penetration
is much more difficult than it would be otherwise. Authentication
traffic with static keys is almost indiscernable from "junk" binary
data traffic if somebody's snooping on the outside.

No. Source code is available for you to write user-space IPSec and
L2TP implementations.

SuSE may already support Openswan out of the box. I don't have a
chance to check ATM if it's already in the kernel.
