[pptp-server] Authenticating but not encrypting or compressing (rh server/w2k c lient)

Fri Dec 15 11:25:03 CST 2000

Hello there,

After much reading and struggling (including reading this mailing list right
back to June) I still can't figure out why this won't work.

The problem is I can't get it to encrypt or compress the tunnel.

I have attached as much info as possible just to show that everything else
seems OK. As you can see below I get authenticated but w2k says
'Compression: (none)' in the status dialog.

The message which seems to be the culprit (and I don't understand it nor
have I found any info on it) is "CTRL: Ignored a SET LINK INFO packet with
real ACCMs!".

My versions are Joey's rpms from http://www.spiretech.com/~joey/pptp/ i.e.
kernel-2.2.16-3, ppp-2.3.11-4 & pptpd-1.0.0-1.

Thank you all in advance for your suggestions,
AJ
