Just a query, do you run any sort of cacheing DNS at your end?

I run a copy of BIND on my Home LAN as both a cacheing DNS and also as a local
DNS. This seems to smooth out a lot of the variables for outbound calls, and
removes the reliance on exteral DNS to some extent. Of course if the issue you
are seeing is not specific to DNS lookups then it may not help at all, but it
may be worth investigating...

Ahaaaa, so I take it you are using a Dial-up connection? yes, that can be
fun.......;-)

A long time ago when I used dialup-IP I had a master script (using OS/2 REXX
but I am sure it can be replicated under any *nx system) that monitored the
Dial-up activity. A CRON job fired off the regular Dial-up events (such as an
IP POLL) and it signalled the REXX script to initiate a Dial-out. Dial-up was
set to NOT automaticaly re-establish a lost link, and REXX would test for my
ISP's DNS for reachability every 60 seconds, then fire off a list of IP related
"Tasks", including one-shot BinkD sessions (1 for each desired connection). It
serialised these tasks so that only 2 sessions could run at a time (limited
bandwidth was the driver here). When all "Tasks" had ended, the REXX script
would bring down the Dial-up link. There was a lot more in it than that but
that was the general idea. 

About 6 months before ADSL arrived here I swapped to using a "Freesco" (a VERY
customised single floppy boot Linux build) box to control the dial-on-demand
function, and it also provided routing, FW, DNS, IP Masquerade (an early form
of NAT) for multiple machine access, but it was not quite as well controlled as
my REXX script was. Dial-up worked great for about 3 years until ADSL became
available, then... bye bye dial-up. I still have that Freesco box here (its an
old 486DX2-66 with 16MB RAM and 80MB HD!) as back up to ADSL but in 4+ years
its never been used. Freesco can run off an old 386 with 4MB RAM and 1.44MB
floppy only if desired, but I figured an HD boot was a bit faster.......;-) It
actually uses a 30MB FAT partition as its boot.

Cheers..................pk.
