Does anyone know why I can call

As a guess: try typing the full path of the command in your crontab?
Or could it be a problem with group permissions?

I use the full paths for all commands. I ran in debug mode having the script start and stop a VPN tunnel but, the ppp log revealed little:

Hello there,
I'm trying to have pptp client running a VPN connection to my college but... I can't !
I have followed this HOWTO and the PPTP gentoo tutorial, googled, and I'm getting crazy about it.
The only thing I know for sure is that my VPN server requires MPPE and MPOA activated in the kernel.
Here is my config for /etc/ppp/peers/mypeer

Your options.pptp file should look like this

Thanks! I actually have made some progress and found out that it is better when this line is not there. But why is that so? My VPN server says that it requires MPPE encryption. :?:

Now, I get the modem hangup message that someone else also had:

Can you show me your options.pptp file, and your peers/my_peer file?

Also, can you run pptp like this

options.pptp

KsE · Posted: Fri Mar 25, 2005 4:48 pm Post subject:

Ok, if not, there is a few things in your peers/my_peer file you should change.

First, do you need a domain when logging in? Like "domain\\user"?

I'll check with the VPN people. I don't think so, but I'll ask them again. I'd like to carry on trying though because it's bank holiday today and on Monday for Easter and I would like to be able to connect before Tuesday! :cry:

EDIT: They are back to work next Wednesday! aaaaarrrggggg...

Hello,
this time I'm at home with my ADSL connection. I get the same kind of modem hangup error message.

If I leave my config files as given before on my previous post, the output of the pppd command is:

@ KsE:

That's a great howto, worked without problems the first time I tried.
Thanks!

That's good to hear. That's why I posted it.

I struggled with this for quite some time. I got help from James Cameron (one of the developers) debugging it for quite some time before I got it to work.

Hi there,
I got some new hints from the VPN server administrator: I do not need a domain name; I should remove the noauth line in my config files. So now I have:
options.pptp

Thanks for all the comments / tips etc in the above posts. After being stuck for quite a while I've managed to get my link working. In this process I've spotted the following which hopefully will be useful to somebody:

minor typo

I actually noticed that typo a few weeks back. I thought I fixed it, guess not. Changed it now.

It's good to see you were able to work through your problem.

The /etc/modules.d/ppp portion was from the official doc. It didn't make a difference if I had it in there, but it might for some since it's in the original doc so I kept it. No harm in having the modules load.

Will this work nearly the same with a 2.4.x kernel instead of 2.6? (the 2.6 wasn't liking my raid devices =(

Hello,

I am still trying to sort out my VPN connection with Linux. I have made some other changes which seem to make things a bit better (THANK YOU Maddog Battie for your post!), but I'm still not able to connect . I would be happy to have some more help! :cry:

Here is the output of the command "pppd call mypeer logfd 2 nodetach debug dump":

Right... I am happy to say that my VPN connection was running well yesterday evening. In fact my previous post here shows that it was probably running quite well last time, but I was too exhausted to notice it! :wink:

However I must add that I have upgraded to gentoo-sources-2.6.11-r5 and reconfigured my kernel from scratch and it probably helped a bit...

hi

I'm having some problems connecting to a vpn... This is the command and the error:

patrickbores · Posted: Mon Apr 25, 2005 9:45 pm Post subject:

I was getting LCP timeout errors, until I examined the traffic with tcpdump. It turned out that I was sending GRE packets, but not receiving any acknowledgements from the server.

Enabling GRE in the kernel solved the problem immediately. Now I just have to figure out how to get it to use the peer DNS server.

Nevermind. Spoke too soon. It just stopped working for no reason.

Hi,

I'm just trying to set up my PPTP VPN connection in Gentoo but when I bring the connection up, my computer seems to try to send infinite amounts of data to it and never receives a response.

Here's the output from pon:
