[lug] Newbie tries to make laptop modem work

[Glenn Murray]

Ken,

This works well to pick out the assigned address!  I can figure out
the sed part to replace a host IP address in an ipchains script, but I
don't know how to handle the waiting-for-the-connection part in a
shell script.  If you or other readers can help me put one together
I'll put it up on my website, but wouldn't it be easier to use
http://www.tummy.com/isinglass/ than reinventing the wheel here?


I imagine a skeleton for a dial-isp.sh script which used a
ip-firewall.sh script as a base would be:

#
wvdial &
# wait for connection...
?
#
# Get assigned IP addr
IP_ADDR=/sbin/ifconfig|fgrep -C eth0|fgrep .... (as below)
#
# Insert IP_ADDR into ipchains script ip-firewall.sh
? sed or tr here >/tmp/tmp-firewall.sh
# 
# Remove old firewall
/etc/init.d/ip-firewall.sh stop
#
# Start new firewall
/tmp/tmp-firewall.sh

Thanks.
