I'm not sure. I simply changed #!/bin/sh to #!/bin/bash

tun is OK, I get as far as seeing the welcome message from the IPSec
gateway.

I made the following diff:
The output below came with this diff:
238c237
< LINE="domain $CISCO_DEF_DOMAIN"
---
> LINE="$LINE $CISCO_DEF_DOMAIN"
Otherwise it seems to just append $CISCO_DEF_DOMAIN to the existing
domain line in /etc/resolv.conf, hence the two domains.
The other error message seems to come from
route delete default
ifconfig -a shows, (in addition to rtls0)
tun0:
flags=10010008d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST,IPv4,FIXEDMTU>
mtu 1412 index 4
inet AAA --> AAA netmask ffffffff
netstat -rn shows
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ---------- ---------
default AAA UG 1 0
CCC 192.168.0.254 UGH 1 1
AAA AAA UH 1 0 tun0
192.168.0.0 192.168.0.1 U 1 3 rtls0
I think that CCC corresponds to the IPSec gateway that I'm connecting to.
One more little thing. If I connect with the Cisco VPN client, it seems
to set an mtu of 1356 rather than 1412. Not sure if that means anything.
Here is the -x output of vpnc-script:
