[gentoo-user] Help With pptpclient

[Drew Tomlinson]

I'm trying to connect to a Cisco 3650 VPN Concentrator at work.  On
Windows clients, I use the included dialup networking client and connect
without issue using pptp.  This is not a L2TP/IPSEC VPN.  I want to do
the same on a Gentoo client.

I've Googled and found that pptpclient should do what I want.  I've
followed this guide:

http://wiki.archlinux.org/index.php/Microsoft_VPN_client_setup_with_pptpclient

I've also come across other guides that are very similar to the one above.

After following the guide, I am still unable to connect.  I see the
following in /var/log/messages:
(Please note that I have replaced the actual IP address with "<IP Address>")

Here are the contents of my /etc/ppp/chap-secrets:

# Secrets for authentication using CHAP

#\'\'   *       \'\'
username        IP Address   password           *

And finally, my connect script from /etc/ppp/peers/vpn:

pty "pptp IP Address --nolaunchpppd --loglevel 2"
name username
remotename IP address
file /etc/ppp/options.pptp
noauth
ipparam IP Address

Any ideas on what I'm missing?  I've been at this for two days but can
not figure out my errors.  In cases where the guide indicates using a
VPN server name, I have tried with both a made up (but common) server
name and the actual IP address as this VPN server does not have a
resolvable name.

Thanks,

Drew

Never mind.  I found the problem.  The VPN concentrator still had a
connection registered for my IP address.  Once that was cleared, I was
able to connect.

Sorry for the noise.
