Hi,
I cannot connect to a vpn gateway. I know the username, groupname and
the passwords. I start the vpnc without config file and enter the
informations at the prompt.
I started vpnc with debug 3. And also logged the traffic on the
interface with tcpdump.
vpnc:
root [at] xbo:~/vpn/vpnc-0.2-rm+zomb.1# ./vpnc --debug 3
Enter IPSec gateway address: xxx.xxx.xxx.xxx
Enter IPSec ID for xxx.xxx.xxx.xxx: xxxxxxxxxxxxxxx
Enter IPSec secret for xxxxxxxx [at] xxx:
Enter username for xxx.xxx.xxx.xxx: xxxxxxxxxxxxx
Enter password for xxxxxxxx [at] xxx:
