I am totally stumped on this one.
Probably because I have so little info.
All I know is that if I leave SIMS "unstimulated" for a period of time, it
stops responding. Mail bounces. Off-site users cannot connect to POP or
SMTP.
Setup:
SIMS 1.8b8 on a PowerMac 7100/80 running OS 8.6 (and nothing else) with its
own IP address.
Was on another machine running IPNetRouter when the problem first showed
up. I moved it to its own machine with its own IP in attempt to fix the
problem.
weird part: I never noticed the problem, only an off-site user (of which
there is one) and only if I had not checked email myself. In other words, as
long as Outlook Express on my G4 logged in now and again to check mail,
there was no problem. The G4 is on a the second of my three IP addresses. So
it looks like there is no problem when accessing the SIMS machine from the
same subnet (the packets from my G4 only have to make one hop to my ISP--or
maybe even just my DSL modem--then one hop back to my SIMS box).
Not my ISP (I think)
My one off-site user never gave me timely or complete feedback for
debugging, but I finally got a 2nd DSL connection (30 day trial ;-) and
could test myself. Sure enough, after a night of inactivity, there was no
response from SMTP, POP, or the HTTP server port on the SIMS box in the
morning. Yet Apache on my G4 (on a different IP address from SIMS) was happy
to serve up web pages when asked--so I am pretty sure my ISP is not blocking
anything (they have no problem with me running servers anyway).
It would not be SIMS, would it?
Is there anything in OS 8.6 that causes Open Transport to shut down (TCP/IP
is set to be On All The Time)?
Thanks for any and all advice.
(and if a reply email bounces you can try: kevinkohrt [EMAIL PROTECTED]
sans the " NOSPAM" part)

Update:
I upgraded the Mac OS on which SIMS is run to 9.1 last night
Still mostly the same problem in the morning.
NO SMTP or POP sockets working.
The SIMS HTTP server was found to be working, but I forgot to check until
after I had messed with a machine behind my firewall (logging in and
changing the NAT IP number and configuring it as a web server)--raising the
question of whether I causes the "internal stimulus" that traditionally
seems to wake up SIMS for some reason. Once I had accessed SIMS via HTTP,
all other systems (POP & SMTP) were go again.
SIMS did continue to receive mail over night, though. But with several hours
gap between batches of mail (which may be normal on a Sunday night).
But why does SIMS log the date whenever it has been asleep for a few hours?
Was it asleep? Or is it just being extra informative for some reason?
