[pptp-server] After clicking the VPN-Icon in Win2K I get the "Verifying username and password" - and that's it.

[Torben Frey]

Hi together,

After configuring around the entire day I am down with my nerves. All I
wanted to do is connecting my Win2K machine to my Linux server using
pptpd. I started a fresh installation this morning, using the new kernel
2.4.5, the mppe-patches (they patched fine without any errors) and pppd
2.4.1., tried the stable and current version of pptpd!

After trying many many different option-files I finally got to the
<http://home.swbell.net/berzerke/2.4_Kernel_PPTPD-HOWTO.txt> , but
nothing helped so far. But here I can show you what happens:

I start pptpd with the following options in /etc/pptpd.conf:
debug
option /etc/ppp/options.pptpd
localip 192.168.111.134-138
remoteip 192.168.111.234-238

In /etc/ppp/options.pptpd I have:
unit 11
debug
name yakul
lock
mtu 1450
mru 1450
proxyarp
auth
+chap
+chapms
+chapms-v2
ipcp-accept-local
ipcp-accept-remote
lcp-echo-failure 3
lcp-echo-interval 5
deflate 0
mppe-128
mppe-40
mppe-stateless

I am using the unit command for preventing pppd using ppp0 or ppp1 which
are usually reserved for my internet connection, but even without,
nothing works (I tried without that, same result). MTU/MRU are smaller
since I am behind a PPPoE connection. But right now I am testing
directly from my home LAN, doesn't work either.

In /etc/ppp/chap-secrets I have the following:
username             yakul           "password"      *

Now, when I click on my VPN-Icon in Win2K, it starts connecting, gets to
the "Verifying username and password" - and that's it. Nothing more.
After a few seconds I get Error 721, the computer is not responding
(sorry, my Win2K is in German).

The logfile (using debug in pptpd and pppd, daemon.debug in syslog)
results only in this:

This happens, no matter if I use the correct user/password combination.
Only deleting all users from chap-secrets gives an earlier error. I
tried almost all thinkable combination of options, there is no firewall
between me and the server at the moment, I THINK it might be a missing
kernel option, but which ones are needed for pptpd? is there a minimal
combination?

Please help me getting this to run!
Thanks a lot,
Torben
