I have been having one heck of a time getting vpnc to work. I initially got it to connect to the conc. 3000 server at my work and I even got an IP address, set up the P2P tun interface and set the default routes, but I could never get anywhere.
The solution was way to easy, I can't believe I did not see it right off the bat. My problem was there where no DNS servers in the resolv.conf that could be found/used, so what I did was tack on the following lines of code to the end of the default vpnc-connect and disconnect scripts and voala, I am golden....
vpnc-connect (Add to the end of the file)
# Set up resolv.conf file
cp /etc/resolv.conf /etc/resolv.vpnc.sv
cat /dev/null > /etc/resolv.conf
echo "domain $CISCO_DEF_DOMAIN" > /etc/resolv.conf
echo 'search (insert search string here)' >> /etc/resolv.conf
for netmask in `echo $INTERNAL_IP4_DNS`
do
echo "nameserver $netmask" >> /etc/resolv.conf
done
echo "$CISCO_BANNER"
exit 0
vpnc-disconnect (Add to the end of the file)
# Remove resolv.conf customizations
if [ -s /etc/resolv.vpnc.sv ]; then
mv /etc/resolv.sera.sv /etc/resolv.conf
fi
exit 0
Note the final exit string was already in the script. I just put my lines before it. Your milage may very. There are many other things you could set up if needs be, just take a look at some of the variables used in vpnc-connect..
enjoy..
