[pptp-server] pptp client and poptop *SUCCESS*

[Cowles, Steve]

Terrelle,

Your post worked!!! Thank you. I can sleep now. But I must admit that the
man pages on pppd are a little confusing... to say the least. From the man
pages on the "name" parameter

       name name
              Set the name of the local system for authentication
              purposes to name.  This  is  a  privileged  option.
              With  this  option,  pppd  will  use  lines  in the
              secrets files which have name as the  second  field
              when  looking for a secret to use in authenticating
              the peer.  In addition, unless overridden with  the
              user  option, name will be used as the name to send
              to the peer when authenticating the local system to
              the  peer.   (Note  that  pppd  does not append the
              domain name to name.)

I guess what threw me, was the "local system" part of the first sentence.
But yet in the options file we (you) are specifying the remote system which
is then matched in the chap-secrets file. This corresponds to the second
sentence. Kind of confusing. I was using the "remotename" parameter. <groan>

Anyway, after a little testing, I came up with the following options file
which is a little more universal.

Thanks again (to everyone) who replied to this post.

================================
/etc/ppp/options on client side
lock
auth
+chap
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless

/etc/ppp/chap-secrets
scowles  * password *
COWLES\\scowles  * password *

And then invoke pptp as follows
pptp enterprise name enterpise user COWLES\\scowles
  or
pptp enterprise name enterpise user scowles

Basically, I'm specifying the name/user paramerters on the pptp command
line. The server side options file I left alone. It is setup per the PopTop
WEB Howto. Before attempting the pptp client nightmare, I was using my
Laptop with NT workstation (SP6) so I needed the MS Domain name in my
chap-secrets file. Either one of the above examples worked.

Hello all!
    After searching through archives and playing around with my settings. I
have FINALLY gotten pptp client ( 1.0.2) working. My setup.

PPTP Client:
linux 2.2.14
PPPD(2.3.10) #module
ppp-driver in kernel ( 2.3.7) <--- this is default with Slackware 7.0
pptp-client 1.0.2
Other modules: slhc,ppp_deflate,bsd_comp
    This client sits behind a linux masq/firewall which is running kernel
2.2.13 ( with ipv4 tunneling and gre compiled in)

PPTP Server:
This server doubles as the VPN server and router/firewall(linux)
Kernel 2.3.13
Modules(ppp,slhc,ppp_deflate,ppp_mppe,bsd_comp)
pptp-server(pptpd-1.0.0)
pppd(2.3.10)

Resources:
Here is my options file on the client side.. not much there:

name name_of_vpnserver
user myusername
password mypassword
noauth
lock
defaultroute
( i have to setup a gateway route for the ppp0 interface when it gets
established, i think its because of the last line of my options.. i'll work
it out later)

Options file on the server:
name name_of_vpnserver
debug
ms-dns 10.0.0.1
ms-wins 10.0.0.106
netmask 255.255.255.0
proxyarp
nodeflate
bsdcomp 15,15
auth
+chap
lock
mppe-40
#mpp-stateless
+chapms
+chapms-v2
defaultroute

Here is my chap-secrets for the client:
# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
hshaw           *       mysecret               *

My chap-secrets on the server:
# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
hshaw           *       mysecret              *

The problem i was having about a week ago was that i hadn't started the
modules first before trying to establish a connection.
*duh!*

So right now i'm connected to my office Lan and my home lan via the pptp
connection thru my ADSL modem.

I hope this helps someone in the future. I would gladly help anyone who
wants to get there linux box setup with a similar setup.
