My PPP connection in Linux seems to work fine for maybe 5 minutes, but
then seams to die slowly. This is, at first I can do ping and telnet
to many sites, while at last even ping to the PPP server I connected
to is failing. If anybody know what my problem is, I would very much
appreciate some help!

(I'm not too good friends with my news reader, so I may miss your
posting.)

My system consists of:

Linux localhost.localdomain 2.0.27 #1 ... i486
pppd version 2.2 patch level 0
U.S. Robotics Sportster 33600 Fax V4.3.174

There is plenty of memory (48M) and disc space.

I use the following to setup the serial port:

setserial /dev/cua2 irq 5
stty crtscts < /dev/cua2

The modem seems to be working fine (and stably) when I do a normal
terminal login. Besides, PPP is running fine to the same ISP from
Windows 95 (which has polluted parts of my harddrive ;-).

Because of W95, my hardware is setup in "Plug and Play" mode. Could
that be the cause of my troubles.

At last I will include a few lines from my /var/log/messages, which
seems to say everything is fine: (I stripped the lines I didn't think
were important.)

Aug 5 14:04:58 localhost kernel: PPP: version 2.2.0 (dynamic channel
allocation)

Aug 5 14:14:27 localhost pppd[1438]: Exit.

Thanks in advance for any help or hints to this problem! Again,

Sincerely,

Anders Buch

Is your phone line dirty ( noisy )?

I strongly believe that my phone line is fine. After all, PPP has been
running problem free from W95 for about a year.

Thanks for your response!

Just one thing, was the local ip address defined by you?

I think that this number should be is assigned by de ppp server. Take a
look at your scripts.

Hi,

It would seem that a noisy line could indeed be the problem. A possible good
fix would be to upgrade the version of Linux to a more current one,
preferably one that runs on the 2.0.3x kernels. The version of PPP that
comes with those kernels seems to be more robust that earlier versions. I
saw that in action where I am, because we also suffer from severe noise on
our lines.

Good bye,

You may also wish to change your modem init string.
On a USR Sportster you can compensate for
a dirty line by changing the init string to include a higher setting
for the S10 register. (Check your modem guide to see if the same
register is used). S10=7 is the default. This sets the duration to
7/10ths of a second that the modem waits after loss of carrier before
* up. You might try S10=21 to see if that corrects the problem.
If it does, you can reduce it to S10=14 to see if it still controls
the problem. The S10 setting allows themodem more time to distinguish
between a line hit from a true hangup by the other modem.

you might have to keep pinging to keep the connection up
