I have successfully installed PPTPd 1.1.2 on my RedHat
Linux 7.2 server with kernel 2.4.19-pre10 and PPP
The kernel has also been patched to support MPPE while
PPP has been patched to support MSCHAPv2+MPPE as well.
All appears to be working properly and I am able to
configure my Windows and Linux clients to connect to
the VPN just fine with MSCHAPv2 & MPPE 128bit enabled.
Jul 23 00:04:35 server pppd: pppd 2.4.1 started
by root, uid 0
Jul 23 00:04:35 server pppd: Using interface
Jul 23 00:04:35 server pppd: Connect: ppp0 <-->
Jul 23 00:04:35 server pppd: MSCHAP-v2 peer
authentication succeeded for test
Jul 23 00:04:36 server pppd: local IP address
Jul 23 00:04:36 server pppd: remote IP address
Jul 23 00:04:36 server pppd: MPPE 128 bit,
stateless compression enabled
Jul 23 00:04:36 server pppd: stateless MPPE
For Windows machines, I am using the MS VPN Adapter
which comes with the OS.
For Linux, I am using the PPTP-CLIENT that is
downloaded from http://pptpclient.sourceforge.net/ .
I noticed that for my Windows boxes, they are able to
reach around 400-500kbps downloading from the VPN
server which is connected to the Internet via a
512kbps leased line.
But for my Linux boxes, they are only able to reach
between 33kbps to 64kbps via the same connection as
the Windows clients. The leased line is totally
unsaturated at time of testing.
Does anyone have any idea what is the cause of this
wierd problem? Or have any performance enhancing tips
Many thanks in advance.
