Back
For some reason, this email client deletes all the received message when I reply
and then select text instead of html... When I get back home and restart the FC4
machine, I'll get back on SquirrelMail. Anyways... I'm STILL trying to ssh into
the bogged down server. No luck yet. I did change the DNS server to send stuff
away from this server in the hopes it would eventuall finish off all those
processes and start accepting my ssh login (to the IP address instead of the
domain). No luck so far. In a couple days I can go hit the reset button.
Besides the modifications to configs suggested so far, I'm also thinking of
adding a hardware watchdog timer to the machine so it'll reset itself should it
ever do this again. I've seen a couple circuits on the web, based on a 555
timer.
One of them I found looked like it could be locked up if the machine crashed
during a watchdog reset. Back when I was designing MC6802 based systems, I did a
watchdog timer like that and had to drive 100 miles in Kansas to hit the reset
switch on a system. Watchdog timers I design now reset on an edge instead of a
level so if the reset line gets stuck at either level, the watchdog will time
out
and reset the system. So, that's my next project!
thanks for the help!
