Problems connecting to pptp vpn

Hey all,

I've been debugging this all day, but I've run out of debugging messages. I'm trying to follow the instructions at https://wiki.archlinux.org/index.php/Mi … pptpclient

I've gotten as far as the debugging command at "making your connection", but the command is terminating with output that doesn't seem to tell me much:

It's possible my options are a little off, but I'm not getting any feedback from that telling me what I might want to tweak. Can anyone suggest anything I can test to get connected here?

I've also had many arguments with network-manager, trying to use the gui, but I'd rather use a netcfg2-compatible setup if I can. Network-manager also did not connect, so I came back to this.

Thanks for any hints,

Dusty

Re: Problems connecting to pptp vpn

Turned out that your user didn't have dail-in permissions, right?

Seems like the server is requesting the client stop the connection.

Re: Problems connecting to pptp vpn

A friend using PPTP-VPN under Knoppix 6.7 challenged me to do the same on my Archlinux system.
So I followed the wiki's instructions, and when I tried to start the VPN I always got the message:

/usr/bin/pppd: pty  option precludes specifying device name

I also tried pptpsetup with the following command-line:

pptpsetup --create tunnel --server connect.xxvpn.net --username xxvpntest --password xxvpntest --encrypt --start

No luck. What am I doing wrong?

Tom.

Re: Problems connecting to pptp vpn

@archthomas.butz:  Pyther is correct.  Your problem seems unrelated to the original issue.  This can only lead to confusion for others doing research in the future.  I am going to go ahead and close this thread.  Please feel free to create to new thread detailing your problem.  If you like, go ahead and link back to this thread from that new thread.

Thanks.
