Hi John
I have a similar problem with BT Openworld under Linux, but a friend of mine
about 20 miles away ( => different exchange etc.) does not. He is running
an almost indentical configuration (also RedHat 7.2) and almost never gets
disconnected. Unlike me, however, he has a brand new machine.
My personal guess is that is not BT, but is more likely your USB chipset. I
use an old PC for my Linux ADSL machine and it has an old Intel chipset in
(with 82371SB USB chip). This apparently has a lot of problems. In time I
hope to swap to a new USB card and hopefully this will solve my them but for
now I can live with it.
In the meantime, I had to solve exactly your problem. My solution works
with RedHat 7.2, hopefully it will make enough sense for you to convert it
to FreeBSD 4.5 ....
I use a CRON script to ping yahoo every 10 minutes. If I get no reply then
I kill the modem and shut down the USB system then restart everything. This
has worked perfectly for months now, sometimes restarting the USB several
times a day. I should really extend the "check_adsl" script to also try
other places such as BBC.CO.UK if Yahoo fails just in case Yahoo is down.
At the moment it relies on Yahoo being on-line, which is a little dodgy.
Hopefully the logs below will help....
Best regards,
Roger

Subject: [speedtouch] Odd modem_run behaviour with FreeBSD 4.5
Hi
Just thought I'd run this by the list to see if any one has suggestions.
I've recently installed the speedtouch modem on a FreeBSD 4.5 box with the
1.1rc2 drivers. The modem connects fine and all is well, except (and I'm
sure this is down to my ISP) I get "frequent" disconnections. By frequent I
mean about once a day, but for ADSL I guess that's frequent. I've noticed
this with BT Openworld even under Linux using Alcatel (kernel) drivers so
I'm fairly sure it a BT thing.
However, that's not the problem - the problem comes when I try to reconnect.
If I do
killall modem_run
killall ppp
followed by
usr/local/sbin/modem_run -v 2 -f /usr/local/libdata/mgmt.o
reconnection fails. It doesn't seem to matter how many times I repeat the
above command (with and without a -m option) or how long I leave it; I issue
the command and it just seems to hang.
If I now pull the USB cable from the machine and wait a couple of seconds
and reconnect the cable and then re-issue the above command all works fine
again. I could live with, except this box is my server and is in a not too
readily accessible place, so having to physically access it to
disconnect/reconnect the cable is a pain.
Does anyone have any ideas about this. Obviously the state of something is
not being re-set properly, but I'm not sure what. I'm really not sure if
this is a problem with the speedtouch drivers or something to do with USB on
FreeBSD.
Thanks
John
