[pptp-server] Poptop Problems (again...)

[George Vieira]

I think your main problem is that the IP assigned is wrong.. I think your
pptp client is not setup right or it's not getting it's IP from the server
correctly..

I didn't notice anything about the client below. If it's a Windows machine
make sure it's DHCP set and if it's *nix or linux then make sure you've got
noipdefault in your options file for pptp.



thanks,
George Vieira

Couple questions...

Background: I'm using pptp 1.0.1 (tried the newer release as well), red
hat 6.2, kernel 2.2.14, ppp 2.3.11. 

i've installed poptop using the directions at
http://poptop.lineo.com/releases/PoPToP-RedHat-HOWTO.txt. basically, i've
followed up to step 4.0 (install poptop, not using encryption, so i don't
need to patch ppp/kernel, do i?).

when people attempt to log on (i've tried win98 and winME so far), they
get authenticated, but the connection immediately drops and windoze
prompts them to reconnect. 

my questions are: what modules need to be loaded when poptop is running?
could someone list theirs? (esp. if they aren't using encryption). also,
are their any steps i'm missing? whenever i test, i always ACCEPT all
packets via IPCHAINS (do i need to exclusively accept port 1723 and
protocol 47).

i'm stuck...have been working on this for a while (as my senior project),
but don't know what to do/where to go next. the thing that puzzles me is
that i can connect (i.e. the tunnel is established), but then i
immediately get disconnected (usually the error reads:

...pptpd[1165]: Peer not authorized to use the remote address 192.168.1.70
...
...pptpd[1165]: Error reading from ppd: Input/output error
...pptpd[1165]: CTRL: GRE read or PTY write failed (gre, pty)=(5,4)
...

so far, i haven't seen anyone else come across the list with a (gre,
pty)=(5,4) error. can anyone tell me what that is or give me any pointers?

your help is much appreciated...
