PPTP VPN connection issue

aihaike · 10-08-2014, 12:30 PM

Dear all,

Im running Slacware64 14.1 and I can't figure how to make my VPN connection working.
I get the error:

Code:

anon fatal[get_ip_address:pptp.c:449]: gethostbyname 'call': HOST NOT FOUND

I've set up 4 files in /etc/ppp:

Code:

#options.pptp
lock noauth nodeflate nobsdcomp

Code:

#chap-secrets
myname myvpn mypassword *

Code:

#peers/myvpn
pty "pptp xxx.zz.w.yyy --nolaunchpppd"
name myname
remotename myvpn
ipparam myvpn
mtu 1490
mru 1490
require-mschap
require-mschap-v2
require-mppe-128
file /etc/ppp/options.pptp
persist

Code:

#ip-up
#!/bin/sh
/sbin/route add -host xxx.zz.w.yyy

I start the connection doing

Code:

pptp call myvpn

Can someone tell me what I do wrong?
Thank you,

Eric.

Actually,

when I do

Code:

pptpsetup --create myvpn --server xxx.zz.w.yyy  --username myname --password mypassword  --start

it does something:

Code:

Using interface ppp0
Connect: ppp0 <--> /dev/pts/4
LCP: timeout sending Config-Requests
Connection terminated.
Modem hangup

I'm really can't figure, hopefully someone already have this experience.
Thank you.

ok so, if I use pppd without --start like this:

Code:

pptpsetup --create myvpn --server xxx.zz.w.yyy  --username myname --password mypassword

Here is what happen when I then call pppd:

Code:

bash-4.2# pppd -d  call myvpn dump debug logfd 2 nodetach require-mppe
pppd options in effect:

Script pptp  xxx.zz.w.yyy --nolaunchpppd finished (pid 22046), status = 0x0
bash-4.2#

I noticed that ppp0 is not up, but during the few seconds pppd is running I can make it up (via ifconfig) by hand and do

Code:

route -n
/sbin/ip route add default dev ppp0

But that change doesn't change anything, pppd still stops.
I've also created a file /etc/modules.conf and containing:

Code:

alias char-major-108 ppp_generic
alias tty-ldisc-3 ppp_async
alias tty-ldics-14 ppp_synctty
alias ppp-compress-18 ppp_mppe
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
alias tty-ldisc-14 ppp_synctty

That doesn't help as well.
