Modem Always On

Modem Always On
« on: December 11, 1999, 03:03:51 AM »
When my e-smith server boots it immediately dials my ISP and stays connected.
It doesn't ever hang up.  At least, it stayed up for at least 2 hours with no traffic.

How can I change this to be a dial-on-demand server?

Thanks.

The e-smith server currently has dial-on-demand as the only configuration for dialup Internet access. Either there is some traffic that you are not aware of, or something is not functioning as it should.

Are you sure that there is no traffic?

My mistake.  I didn't wait long enough.

Thanks!

My e-smith server has been connected for almost 24 hours now.  I suppose
one of my Win95 machines is keeping
it up.  How can I find out which machine?  Is there any way to monitor the traffic?

It's easy to see if there are active TCP connections. Log into the server.
"netstat -t" will show any TCP sessions into or out of the server.
"netstat -M" will show any IP masquerade sessions.  Non-session
oriented traffic, e.g. DNS lookups will be harder to detect, you'll have to do some more reading if your mystery is not solved by the above routes.

Found it!   One of the Win95 machines had Real Player set to check for content and updates.  I changed it to not do that.

Yes, I found it with netstat -M.

Thanks for your help.
