I originally bunged most of this onto the "DTR Dropping" thread, then thought
better of it. Sorry if it's redundant to some of you.
Let me preface this by saying that all ports idletime are set to 10 mins, except
my backdoor port which is set to zero (no time out). We're an ISP, using
PM's for remote POP's. We've got 10 PM's scattered all over.
The problems are not site specific, but network wide.
Got an ongoing beef from some users that they get kicked off the system
after a minute or two with a "NO CARRIER" msg. Other users say the duration
of the session prior to kick off varies. Got other users who either aren't
getting kicked
off, or are to lazy/whatever to gripe.
I personally get kicked off the system after between one and two minutes _every
time_ I call in from home -- and trust me, it's not an inactivity problem in
my case.
Then when I call right back, I can be on indefinitely.
(This is making me crazy, can you tell???)
And this situation happens no matter whether I dial into the backdoor port or
the common modem bank. I live smack between two of our sites, so both are
local calls from the house. It happens on either/both PM's. I can also dial
long distance to verify this from our other PM's.
The user's software and hardware (modems) vary across the spectrum.
Text users have Procomm (and +), Telix, Windows Terminal (shudder), Hayes
Smartcomm, etc. SLIP and PPP users use Trumpet Winsock, MacPPP, OS/2
whatever, Win 95, you name it. Modems -- I've been kicked off using Microcom,
Hayes, USR, Zoom, PPP -- everything from an old Hayes Personal 2400 thru
USR and PPP 28.8's.
On the POP end, we're using Zoom's, Hayes, and Supras -- all sites are
homogenous,
no mixes at any site, except my backdoor modem's a 28.8 USR.
We're using 3.1.2 PM software, SunOS 4.1.3 on the server and using Radius
for authentication.
Maybe I can't see the forest, but I can't figure out what's causing this.
Any further suggestions/comments/opinions welcome. And knowing this
group, there'll be opinions, at least :-)
