I’m running Ubuntu 12.04.1 wheezy/sid and I needed a way to connect to the office Nortel VPN server. On a Windows machine you normally use Nortel Contivity Client. But this is not available for Linux. There is a nortel branch available of vpnc which you can find here.
The first step is to install svn-buildpackage, use the command below for this. There some extra packages coming with this install, but this is OK.
apt-get install svn-buildpackage
Now you can do a check-out on the SVN repository:
svn co -r517 http://svn.unix-ag.uni-kl.de/vpnc/branches/vpnc-nortel
This downloads the files in a new directory (vpnc-nortel) in the location you are at this moment.
Now it is time to install the vpnc client. go to the vpnc-nortel directory you just downloaded and perform the command:
This should make the compile the files for your OS, but the first time this failed form me with the error message:
Package gnutls was not found in the pkg-config search path.
Perhaps you should add the directory containing `gnutls.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gnutls' found
To solve this issue you should first install libgnutls-dev:
apt-get install libgnutls-dev
Then you can try again:
The make install should give an output like this:
root@ubuntu:~/vpnc-nortel# make install
install -d /etc/vpnc /usr/local/bin /usr/local/sbin /usr/local/share/man/man1 /usr/local/share/man/man8 /usr/local/share/doc/vpnc
if [ "`uname -s | cut -c-6`" = "CYGWIN" ]; then \
install vpnc-script-win /etc/vpnc/vpnc-script; \
install vpnc-script-win.js /etc/vpnc; \
install vpnc-script /etc/vpnc; \
install -m600 vpnc.conf /etc/vpnc/default.conf
install -m755 vpnc-disconnect /usr/local/sbin
install -m755 pcf2vpnc /usr/local/bin
install -m644 vpnc.8 /usr/local/share/man/man8
install -m644 pcf2vpnc.1 /usr/local/share/man/man1
install -m644 cisco-decrypt.1 /usr/local/share/man/man1
install -m644 COPYING /usr/local/share/doc/vpnc
install -m755 vpnc /usr/local/sbin
install -m755 cisco-decrypt /usr/local/bin
The last thing to do is to edit the configuration file to the settings of your company. In my case this configuration file (/etc/vpnc/default.conf) looks like:
IKE Authmode gpassword
Enable Single DES
IKE DH Group dh1
Now your ready!
