PostPosted: Mon 22 Aug 2011, 10:48    Post_subject:  How to setup VPN?  

I've done a search for this problem but have not yet found a solution.

I'm trying to setup a vpn in Puppy(tried in Lupu and Slacko so far) by adding the 'VPN server,login and password to 'Gppt PPTP VPN Client' but when I hit the connect button I get this.

'Connecting to VPN server...
PPTP client (30430) exited with 0'

Any help appreciated.

It's an obvious question - but are you sure your VPN server is MPPT-MPPE?

Might it be OpenVPN or CiscoVPN instead?

Hi tempestuous/disciple

Thank you both for trying to help with the VPN issue.
There really was no outcome and the reason for not following up on it to date.
I'm merely using the information from the link below,opening up 'GPPTP PPTP VPN Client' from menu> network,adding the info to the fields but it wont work.
I know the VPN works itself as I can easily use it in both Windows XP/7.

OK, that's why we ask users to reveal the results of advice we provide. Now we know the full details of what you're trying to achieve, not just one or two technical components thereof. Now we know:
i) the details of the VPN server you're trying to connect to - http://uk.gofreevpn.com/
ii) and that this server is, indeed, PPTP and is thus truly compatible with gpptp.

Now there's an additional advantage of providing feedback: we can troubleshoot the problem!
I went ahead and tried the uk.gofreevpn.com connection details in gpptp myself (after making the minor configuration adjustments explained by jafadmin) ... and it works !
Sure, the "PPTP client exited with 0" message doesn't look positive, but when I opened /var/log/messages I saw these lines -
Code:
pppd[5047]: CHAP authentication succeeded
...
pppd[5047]: local  IP address 10.38.1.7
pppd[5047]: remote IP address 10.38.0.1
pppd[5047]: primary   DNS address 8.8.8.8
pppd[5047]: secondary DNS address 8.8.4.4

Then I just needed to change the route so my network traffic goes via this tunnel, as such -
Code:
ip route add default dev ppp0

Now when I go to http://whatismyipaddress.com/
I see that I have a UK IP address !!

All looks good to me.

That's great,I'm pleased it does work.
Only problem is,I don't understand jafadmin's post..Could you explain further where to place your line of code?
Thanks

1. in /etc/ppp, copy "ip-up-EXAMPLE" to just "ip-up"
2. in the /etc/options.pptp file, uncomment the: "require-mppe-128" line, and save the file.

... but I see that jafadmin made a typo with 2. - it should be /etc/ppp/options.pptp

and sorry, I now see there's one more tweak necessary:
3. in /etc/ppp/options.pptp comment out the "refuse-chap" line (add # to the start of the line).

Now you're ready to run gpptp. When it exits, wait a few seconds and you should see a second connection icon appear in the tray.
Now would be a good time to open /var/log/messages just to see what's going on.

Then the "line of code" you refer to is a command you must run (in a console) -
Code:
ip route add default dev ppp0

Might not be a typo - I have a feeling it might have moved over the years Wink

Success!It works now after following your instructions.
The only thing I don't see is a second connection icon appear in the tray?Also,the disconnect button is greyed out in gpptp so I have to reboot to lose the connection. I'm using Lucid 528.
Thanks for your patience.

IIRC you'll find something in the thread about a route command to restore your normal networking without rebooting.

You were right.It seems I found the same problems as you, i.e. unable to disconnect.

What I did was,download 'gpptp-mod.zip' extracted it and then ran the newly created'gpptp'file.(I had previously assumed that 'gpptp' would be up to date in the newer versions of Puppy.This isn't the case).
The 'disconnect button now works and without the need to kill or reboot.

Thanks for your help guys Very Happy

Oh ya - That thread really helps the average user -
(/sarcasm)

"Since I'm connecting from a routable IP address, I create a script to route all non-routable (RFC-1918) networks using my "ppp? - inet addr" address as the gateway. What this does is make available to me all RFC-1918 networks that route back to the vpn server I connected to. "

I routinely use both MS VPN and Cisco VPN (both in Windows and in Ubuntu) and trying to get gpptp set up and running is a total mess. These forums are littered with posts of those that never did get a connection. It's a shame that something that works so easy in other distros and OSs has to be such a mess in Puppy.

Are you having trouble connecting to a VPN yourself?

1. I didn't have a clue what the state of gpptp was in their version of Puppy (Now that we know, feel free to try to get people to include improved/more up to date gpptp packages when they make Puppy).
2. I couldn't remember it all because it was so long ago.
3. I didn't have access to a VPN to test myself.
It therefore made sense to point that thread out because I knew it contained the needed information. If someone didn't understand it they could always ask for more help.
In the future I can point to this thread instead, and people can even test with a free VPN first!

Its a shame that Puppy doesn't have decent infrastructure for people to help with package management, improvements and documentation...
But feel free to write a wiki page or something.
