VPN...help me

[ervalerio]

hi there
i'm somewhere in trouble trying to get my vpn client up&working.
I'm a mandrake (2.4.8-26mdk)-no-recompiled-kernel user.
This is how the situation is now:
[root@localhost pppmodulo]# pptp uib-vpn-gw debug name ******* noauth
(unknown)[2461]: log[pptp_dispatch_ctrl_packetptp_ctrl.c:531]: Client connection established.
(unknown)[2461]: log[pptp_dispatch_ctrl_packetptp_ctrl.c:637]: Outgoing call established.

so the client seems to work..but having a look with ifconfig, there's no any ppp0 interface..
how can I turn up a ppp0 interface?
ppp_generic,ppp_deflate and ppp_async are all loaded as modules. My connection doesn't need mppe (even if I tried using it aswell).
thanks
Valerio

Sounds like your not getting authenticated, what do you need to use chap or pap? Then check your option.pptp file for +chap or +pap as required. Make sure the user password combo is in either /ppp/chap-secrets or /ppp/pap-secrets. you may have to "user <name> on the command line when starting pptp. <name> should be the username that is in the chap-secrets or pap-secrets files. Without seeing some config files, I can't pinpoint the problem. Also use "debug" on the command line after the "noauth" to get the chat sequence logged to /var/log/messages.

Hope this points you in the right direction....
man pppd is you friend.....

thanks for answer!.
Here it is:
this is the log (as you can sees)

Aug 31 01:28:41 localhost pppd[2202]: Using interface ppp0
Aug 31 01:28:41 localhost pppd[2202]: Connect: ppp0 <--> /dev/ttya0

Maybe the problem is in here, but i don't know how to solve it..maybe there's some symbolic link between ppp0 and /dev/ttya0 , but i searched for that dev in /dev/ and it didn't exist!.
This my routing table at the moment:

Kernel IP routing table

0.0.0.0 10.10.64.1 0.0.0.0 UG 40 0 0 eth0

and my ifconfig:
[root@localhost pppmodulo]# ifconfig

[root@localhost pppmodulo]#

i cheched about pap-secrets and chat-secrets (i have to use the first one), and everything was all right with passwords and username. I also tried to use the option user <name> without any good results.
thanks again

Don't think that was with debug or you cut the logging short...

http://pptpclient.sourceforge.net/howto-diagnosis.phtml#debug

has good deal of info.

What's in /ppp/options.pptp? /ppp/options? /etc/modules.conf?

My RH 7.3 shows ppp0 <--> /dev/pts/2
My RH 6.2 shows ppp0 <--> /dev/ttyp0

You might be on to something... which version did you install and how? rpm? tarball?

Might just need to upgrade pppd, that is just a guess at this point.

hey your at the same place as 'puccio' from this thread:

http://linuxnewbie.org/forum/showthread.php?s=&threadid=60328

[ervalerio]

I installed pppd as rpm.
Maybe this can be useful:
cat /etc/sysconfig/network-scripts/ifcfg-ppp0
DEVICE="ppp0"
ONBOOT="no"
USERCTL="no"
MODEMPORT="/dev/modem"
LINESPEED="115200"
PERSIST="yes"
DEFABORT="yes"
DEBUG="yes"
INITSTRING="ATZ"
DEFROUTE="yes"
HARDFLOWCTL="yes"
ESCAPECHARS="no"
PPPOPTIONS=""
PAPNAME="ervalerio"
REMIP=""
NETMASK=""
IPADDR=""
MRU=""
MTU=""
DISCONNECTTIMEOUT="5"
RETRYTIMEOUT="60"
BOOTPROTO="none"
PEERDNS="yes"
I copied options.pptp from Puccio's configuration.


I've upgraded to pppd 2.4.1 (it was 2.4.0),but still not working.
/var/log/messages:
Aug 31 10:08:58 localhost (unknown)[2092]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:531]: Client connection established.
Aug 31 10:08:59 localhost (unknown)[2092]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]: Outgoing call established.

Aug 31 10:09:29 localhost pppd[2095]: Connection terminated.
Aug 31 10:09:30 localhost pppd[2095]: Exit.

I know, I'm on the same network as Puccio,and I will not have any problem about routing...but I just can't fix my routing table without a ppp0 interface.
how can I help you more to pinpoint the problem?

[ervalerio]

everything works fine now!
I used this script:
#########
# PPTP-ON
#########
#!/bin/bash
/bin/rm -f /var/run/pptp/* 1>/dev/null 2>/dev/null
/usr/sbin/pptp uib-vpn-gw debug name xxxxxx noauth debug
sleep 10

and everything magically was fine!:-))
Thanks for your help!
