Tom et al.
I am able to get it going now. I was confused on how to
use a blank space as a delimiter and cout not find the
reference to the '\' as a delimiter. It now works for
capturing the new IP address when I dial into my ISP.
Firewall is now working and maybe I won't get hacked for a
while.
Is the use of the '\' as a delimiter part of the bash
shell scripting? I am presuming this since it isn't
mentioned in the man page.
Thanks everyone for your help with getting my box
reinstalled,upgraded, and recompiled; diald running again
even though portions are not mentioned in the HOWTO [I
figured out that a lot of new stuff has been added for ISDN
and other POTS dial-up connections; and with the scripting
necessary to dynamically pull the new IP address each time
ip-up fires.
MERRY CHRISTMAS!!
