hi all,
who can tell me where can i download Linux VPN Client?

test it out

http://pptpclient.sourceforge.net/


or say for what *nix system

and now google is your friend

Usual it doesn't work as VPN client from windows!

try this one
http://www.unix-ag.uni-kl.de/~massar/vpnc/

But In my oppinion, its good. Works fine for me. Almost just like a Windows VPN Client, except :

1.I did not add MPPC so my Client does not had Compression support.
2.My Client Just supports, MS-CHAP, CHAP, MS-CHAPv2 and SRP-SHA1 for authentication.
3.My Client had problem with EAP-TLS, I mean it does not support it. I guess, The problem Specially occures when the PPTP Server(Microsoft's) uses a RADIUS Server for authentication.

After all, It's fine
