Re: N800 VPN Client. Cash Reward?
 

An update...

I replaced the ip-up with the following

Is this correct? is PRIMARY supposed to be wlan0 or eth0 or something else? I changed it to wlan0 and SERVER to the IP of the VPN server. Anything else I'm missing?

Re: N800 VPN Client. Cash Reward?
 

This is the script that I added to the /etc/ppp/ip-up.d/ directory.

Note: this will only work for the Indiana University VPN. It does work though, most of the time.

And for some strange reason, visiting 'http://www.metafilter.com' from the N800 over the VPN immediately starts generating VPN errors, and kicks me offline. I've not noticed it with any other website. However, I can get around that by using 'SSH -D' and proxying my web connections through another machine. The important thing, is that I now get packets.

Thank you so much.

#!/bin/sh
# pppd ip-up script for all-to-tunnel routing
# name of primary network interface (before tunnel)
GATEWAY=`route -n | grep "UG " | awk '{print $2}'`

# if we are being called as part of the tunnel shutdown
if [ "${GATEWAY}" == "192.168.1.1" ] ; then

echo "Connecting to VPN from non-IU network"

route add -host 156.56.245.6 gw $GATEWAY

Hi,

For this last bit, can you explain what the IPs listed are? I mean, where did you get these from? I know its specific to your school, but I would like to find the equivalent from my school, so it would help if you can explain those IPs. Thanks!

route add -host 156.56.245.16 gw $GATEWAY
route add -host 156.56.245.6 gw $GATEWAY
route add -host 156.56.245.7 gw $GATEWAY
route add -host 156.56.245.13 gw $GATEWAY

Sorry, I can't provide much help here.

My school has a "how to setup your VPN under linux page" which mentioned two different sets of routes that need to be setup, depending on if you're connecting from our wireless network or from home. I used their info.

Re: N800 VPN Client. Cash Reward?
 

Hi,

Can you post the link to that webpage? I want to compare information to get some clues. :)

hey guys,

here is my functional configuration:
http://www.lancode.de/public/pptp.png

and these lines make it work after building up the tunnel:
note: i had to set the mtu value to 1416 in /etc/ppp/options! it caused immense problems no to set it . so, perhaps thats your problem too...
here is a copy of my route output:

Re: N800 VPN Client. Cash Reward?
 

awesome work guys!

I'm getting back in town today, and don't have access to a linux computer right now to do the flash, but I'm gonna install it. But it looks like you guys got it to work!

I did offer a small reward for this, so if it works, do I owe someone some money? I'm a man of my word...

If not, I think I'm gonna make a quick frontend for the VPN just to make it easier to launch and we can consider that my contribution to the project :)

Yay!

Hi Loki,

Thanks for your help! I think I'm ALMOST there....

I managed to get a stable connect now, esp that tip about the MTU 1416 helped alot.

I have another problem now. I managed to get the tunnel up, the routing etc. But..when I try to ping anything with URL, it doesn't work (eg. ping www.google.com doesn't work) but if I ping 209.85.135.103 it works. That means, I have no access to the DNS.

I noticed that when I did the pon, the debug has this line

Cannot detemine ethernet address for proxy ARP


I wonder if that has contributed to the inability to access the DNS? So I'm pretty close to the end....just need to have some way to resolve the URLs!

If the DNS were
Primary DNS: 130.95.128.2
Secondary DNS: 130.95.128.1

how do I go about adding them in linux? Do I simply add them to the resolv.conf file? Or is there a temporary add only when I need to use the VPN?


Luke

Re: N800 VPN Client. Cash Reward?
 

Ok, adding the 2 DNS to my resolv.conf makes everything work!

What if I want to connect to a different network? Would having them there interfere in any way?
