PPP Dialin Problems

PPP Dialin Problems

Post by Kevin Micalle » Mon, 20 Oct 1997 04:00:00



I am having some serious problems with my PPP dialin under Red Hat 4.2. I
have included my ppp-on and ppp-on-dial scripts as well as some sample
output to my system log.

Note that the first entry in the system log is for my one and only
successful dial-in. What follows is a sample of the failed dial-ins (I've
made dozens and dozens of failed dial-ins). Note that in the failed
dial-ins, the prompter for username is identified and when the text for my
username (micallef) is downloaded, only the last few letters, or most
commonly, only 'f' is sent to the server.

Could this problem have something to do with that 8-bits thingy or could it
be the result of a noisy connection? Please note that I am able to dial-in
with Windows95 with no difficulty. Oh, I'm a bit of a newby.

Regards,
Kevin Micallef

PPP Dialin Problems

Post by Michael Waldro » Mon, 20 Oct 1997 04:00:00


If you are having "garbled" text returned over your isp link running ppp
have you checked the modem under another operating system such as windows?
If all work well under windows then I would suspect your Linux OS setup.  If
you can backup your files either to tape or disk I would do so.  Another way
is if your windows95/3.1 disk is part of your system then mount that
partition and move files to it then reinstall Linux.
On the other hand if you are having the same problems with Windows95 and
Linux then I would suspect your modem or serial card as being at fault.  I
had a modem go bad which exhibited slow connections, stalls, bad data, and
forever to download files both in Windows95 and Linux.  I got the modem
fix/replaced and it works fine now.

1. User-PPP Dialin Problem.

I configured dial-in PPP on a FreeBSD 3.3 box using "First Method" in the
PPP man page and have found an occasional problem.  What happens is a user
tries to connect and they are unable to negotiate a connection so they hang
up. In this situation the PPP process on FreeBSD sometimes does not
terminate and the modem device is not released. This problem seems to
happen when the remote PPP configuration is not compatible with the FreeBSD
setup in some way so the protocol negotiation is not successfully completed.
It is easy for a user to disable all 4 modems on the server if they keep
trying to connect.

Is there some way to ensure that the FreeBSD PPP processes always
exit and release the modem devices when carrier is dropped?
