 |
|
Hi there.
Because I have only a very limited amount of international trafic from my ISP, I would like to conect via VPN to my University.
But although that's fairly easy in Windows, in linux is not the case.
I've read an setup procedure for Red-Hat, but I didn't understand lot's of the terms used and in the end ... I couldn't get the connection to start.
I don't understant why do I have to give so much info to pptd-command, in windows I just give the ip of the VPN server (ex: 111.111.111.11) and that's it.
Can anybody give me, or point me to more easy to follow configuration of VPN ? |

Hello,
I just did this myself but using a LAN an not a PPP, but I guess it will be similar for dialup.
I learned this using a document for our university, if you are already on the lan, so perhaps it is not very useful to you. And I don't find the digital version anymore on the net, lost the link... 
I hope everything is clear.
0. Get an internet connection to your local ISP (call this ppp0, from now on)
1. Get pptp
Execute this
| Code: | lynx http://sourceforge.net/projects/pptpclient
tar zxvpf pptp-linux-<version>.tar.gz
cd pptp-linux-<version>
tar zxvpf pptp-linux-<version>.tar.gz
cd pptp-linux-<version>
make
cp pptp ../pptp-command /usr/sbin |
Now change pptp-command to disable taint-checking (== remove T in first line)
2. Get mppe-ppp (for encryption, depends on VPN router I guess)
| Code: | lynx http://sourceforge.net/projects/pptpclient
tar zxvpf ppp-mppe-<version>.tar.gz
cd ppp-mppe-<version>
sh unpack.sh
cd ppp-<version>
./configure
make
make install |
3. Config
Add "<username> rtrvpn <password>" using
| Code: | | nano -w /etc/ppp/chap-secrets |
Add VPNconnection configuration using
| Code: | | nano -w /etc/ppp/peers/VPNconnection |
# is NOT a comment!!!
| Quote: | # PPTP Tunnel configuration for tunnel VPNconnetion
# Server IP: <IP address of VPN Server>
# Route: add default gw <IP address of VPN Server>
noauth
lock
debug
ktune
name <username>
remotename rtrvpn
mppe-40
mppe-stateless
mtu 1000
|
Copy net.ppp0 (used to dial in to your ISP) to net.ppp1 and make it do something like (this won't work, but you'll manage to make it do what you want, won't you?):
| Code: | | /etc/init.d/net.ppp1 |
| Quote: | start () {
$SUBNET = `/sbin/ifconfig ppp0 | /bin/sed -n '2p' | /usr/bin/cut -d: -f2 | /usr/bin/cut -d. -f1-3`
/sbin/route add <IP address of VPN server> gw $SUBNET.254
/usr/sbin/pptp-command start VPNconnection
}
stop () {
route del default
pptp-command stop
pptp-command start VPNconnection
}

Greets,
Wouter
PS: I would have put my config files on the net, but I'm in windows for the moment, so no config files |

I believe I must use pptp to connect to my VPN server.
Acording to the How-to you pointed me (thanks for that) a windows VPN uses pptp.

Thanks for the links but neither helped me, who is in a situation kinda like the thread owners.
In order to use my campus's wireless connection I have to make a VPN connection. In windows its simple, you just open the provided Cisco VPN client and connect to 10.10.1.10 then it asks for your logon name/password for the network.
Aiiee, i just want wireless! |

Hi there.
Tanks for the help, I haven't been able to test what wdconinc described because I've bought a new motherboard with onboard lan, and I haven't reinstalled gentoo in my (almost) new computer because I think the distro does not have a driver for the lan onboard ... I'll look better.
Anyway thanks for the support, has I said i think wdconinc has the easiest setup, although I don't understant that first step about the isp and the ppp connection ... I configure my conection with dhcp, so I'll just jump the 1st step wdconinc described (I hope it's not a critical step).
Thank you again. |
