PPP connection dropping after a few minutes

[marshal@h9.dion.ne.jp]

Hi all,

This may be slightly off-topic, but I think this may be two of the
better forums to help me solve this problem.

I'm connecting through FLETS ISDN under KDDI DION here in Japan.  If
this makes no sense, don't worry about it too much.  I don't think it
may make a difference, but for the Japanese user, they may be able to
help.

Recently (today), my connection has been dropping ever few minutes.
My connection drops regularly every 10 hours, as I think they put a 10
hour time cap to connections.  Every so often, it randomly drops,
usually due to my USB hub dying or something.

But today, it's been dropping every few minutes or so.  Nothing
regular, except this in the /var/log/syslog:

It's that "No response to 4 echo-requests" that gets me.

There was something similar to this that happened under MacOS 9 (I'm
running on a PowerBook.)  The Remote Access under MacOS 9 won't hold a
connection.  It drops after a few minutes.  So I had to use FreePPP.
Anyone knows what's the difference.

I'm going to check FreePPP under MacOS 9 and see if the problem still
exists there, but I though I'd get this off for any ideas on what may
be the cause.

Thanks for the help.

Marshal
