Does polbox have any mirrors? I've been trying to contact http://www.polbox.com/h/hs001/ for the last few weeks with no luck (it times out). Are other people still seeing polbox?

OK, per chance, it worked today. The new link for the MPPC stuff is http://mppe-mppc.alphacron.de/

sorry..djbanaan
i configured all for slackware server...

but wen i try to connect from windows client appear
error 800 unable to conecto to client..

eder_michael11 · 06-05-2006, 02:16 PM

i turned off the firewall the questions that i have are....

at the menu config ... in the kernel the options for PPP i selected like this

<M>PPP (point-to-point protocol) support
[ ] PPP multilink support (EXPERIMENTAL)[*] PPP filtering
<M>PPP support for async serial ports
<M>PPP support for sync tty ports
<M>PPP Deflate compression
<M>PPP BSD-Compress compression[*]Microsoft PPP compression/encryption (MPPC/MPPE)

if this is ok??

well other think i think could be the error for not connect the client windows to my server linux is that

/etc/pptpd.conf didnt exist at my slackware i have to copied from the directory /pptp-2../samples to /etc

other thing the file /etc/ppp/options.pptpd doesnt exist only existe
/etc/ppp/option .. i have to copied to this location from the samples too

my slackware version is 10.0
can you helpe to find wich is the error?? i can answer all you ask me please...

A problem!
I did everything as written in Djbanaan's article and ... found two problems:
1. libwrap.so.0 is missing and I can't find it for Slackware (???). Problem occurs when pptpd is started "properly" (/usr/sbin/pptpd). However, when I start pptpd directly from command line, it doesn't ask for libwrap.so.0 and runs.
2. when pptpd is running I can't connect using windows xp sp2 client. Returned error code is 619. Firewall is, of course, off.

What is wrong?

(slackware 10.2)

I haven't ran slackware since around 1999 i've been on ubuntoo lately or whatever it's called. But setting up a VPN on a shared hosting account isn't that fun you should just get a dedicated server if you can afford it maybe split the cost with some friends.

Although i'm not a big fan of slackware linux i know it's the toughest one of them all (along with debian if i'm not mistaking). People now are starting to use linux more and more (which is a good thing) but the similarities between linux and windows (i'm referring to the graphical user interface) are just annoying. I know they must make it pretty and all but cmon...
Anyway I'll always love linux and my web hosting plans run under linux really well.

I have just configured my PC to connect to my daughter's University using VPN.

The steps I needed were these

1. Install pptd package from slackbuilds

2. add to rc.modules
/sbin/modprobe ppp_mppe

3. mkdir /etc/ppp/peers

4. symlink bin/ip to sbin/ip

5. Create file

/etc/ppp/ip-up

Quote:

#!/bin/sh

/sbin/route add -host

and make it executable

6. pptpsetup --create imperial --server NETWORK_ADDRESS --username USERNAME --password PASSWORD

7. pppd call imperial dump debug logfd 2 nodetach require-mppe

this gets ppp0 running

8. /sbin/ip route add default dev ppp0

This adds ppp0 to the routing table

9. We can then connect to her folder using konquereor

smb://icfs.cc.ic.ac.uk/username

10. login as ic.ac.uk\username

I just used your guide arubin to connect to bristol university vpn. Thanks a lot!

Just a couple of things I noticed though:

The package you want from slackbuilds is "pptp" not "pptd"

When I ran

Code:

pppd call imperial dump debug logfd 2 nodetach require-mppe

the last line of output was

Code:

Can't execute /etc/ppp/ip-up: Invalid argument

I tried running

Code:

route add -host

as root in a separate console and it doesn't do anything. I tried connecting without the ip-up script present and it worked fine.

Either way I can access my files stored at uni now, thanks again!

I'm trying to connect from my home to my vpn service ipredator.se using slackware 13.1.

I managed to set up the client correctly and it connects to the vpn.
This is the output from /var/logs/messages:

pppd[3307]: CHAP authentication succeeded
pppd[3307]: MPPE 128-bit stateless compression enabled
pppd[3307]: local IP address 93.182.149.27
pppd[3307]: remote IP address 93.182.149.2

This is output of ifconfig:

ppp0 Link encap:Point-to-Point Protocol
inet addr:93.182.149.27 P-t-P:93.182.149.2 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1496 Metric:1
RX packets:5 errors:0 dropped:0 overruns:0 frame:0
TX packets:180 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:62 (62.0 B) TX bytes:79893 (78.0 KiB)

My problem is setting up the routing for the connection to go from the vpn server to eth0

when I type:
route add -net 93.182.149.0 netmask 255.255.255.0 dev ppp0

that doesn't work. If anyone could help it would be much appreciated
Thanks
