Hallo, Liste,
i got some problems with mac-os 10 clients on my poptop-server.
windows 2000 und XP are working well: fast and stable connection,
while the mac doesnt get to the ppp-connection properly.
mac-client (with the internal pptp-client, btw) gets an IP from the
server, then connects via pptp, than comes an LCP ConfReq-Message
(gre-pakete...!?), die kommen auch beim client an; der sagt dann
Jun 23 13:08:49 access pppd[5233]: sent [LCP ConfReq id=0x1 <pcomp>
<accomp>]
at this point theres a break for 30 seconds... than follows:
Jun 23 13:09:16 access last message repeated 9 times
Jun 23 13:09:19 access pppd[5233]: LCP: timeout sending Config-Requests
Jun 23 13:09:19 access pppd[5233]: Connection terminated.
Jun 23 13:09:19 access pppd[5233]: Exit.
Jun 23 13:09:19 access pptpd[5232]: Error reading from pppd:
Input/output error
Jun 23 13:09:19 access pptpd[5232]: CTRL: GRE read or PTY write failed
(gre,pty)=(6,5)
Jun 23 13:09:19 access pptpd[5232]: CTRL: Client 10.28.52.198 control
connection finished
Jun 23 13:09:19 access pptpd[5232]: CTRL: Exiting now
with tcpdump I can see, that the client receives packets:
07:42:54.513953 IP 10.28.52.1 > 10.28.52.197: call 1361 seq 7
gre-ppp-payload
07:42:54.513953 IP 10.28.52.1 > 10.28.52.197: call 1361 seq 8
gre-ppp-payload
after the 10th or so payload the connection shuts down from the servers
side:
Jun 23 13:09:16 access last message repeated 9 times
Jun 23 13:09:19 access pppd[5233]: LCP: timeout sending Config-Requests
Jun 23 13:09:19 access pppd[5233]: Connection terminated.
Jun 23 13:09:19 access pppd[5233]: Exit.

tcpdump on the server says:
14:56:15.954532 access.hfk-bremen.de > 10.28.52.198: gre [KSv1] ID:0995
S:8 ppp: Conf-Req(1), MRU=1450, ACCM=00000000, Auth-Prot CHAP/MSCHAPv2,

and then nothing more....
system server: suse 9, poptop 1.1.2, pppd2.4.2, kernel 2.4.21,
ppp-module loaded.
system client: mac powerbook w/ internal airport extreme, pptp-client
