1. PLEASE HELP -- modem & ppp problems
Hi all
I got a weird problem. I can connect to my ISP ok, but whenever I try to
redial (if I disconnect) it just doesn't work properly. pppd just sits
in memory for about a minute and then dies.I figured out a way to get it
working. To redial I have to start it, then stop it and start it again.
However, if I do that too many times (sometimes as little as 1) it just
totally hangs and doesn't dial at all no matter what I do. The only way
around that that I know is reboot. Needless to say it's extremely
inconvenient. It appears as if pppd does not reset the modem properly
when it dies. After that neither ppp nor minicom nor anything else can
access the modem. Does anybody have any idea what might be wrong?
To add to that I also got another problem. I think I got a weird ISP.
Sometimes I can connect no problem but sometimes pppd just sits there,
times out and dies. I believe it's related to the way they authenticate.
Couple of times I connected using minicom and got a login prompt (like
terminal authentication) but other couple of times I got garbage on the
screen (pap). It looks like sometimes they use pap and sometimes they
don't. Although this does not affect windows. Could there be another cause
for that? How can I solve the problem?
Finally, my ip masquarading doesn't work properly. I can receive
everything, but I can't send anything out. (mail, news, -- nothing). How
can I fix that? This is the file that gets executed automatically every
time I connect:
#!/bin/sh
ipfwadm -F -p deny
ipfwadm -F -a m -S 10.0.0.0/0 -D 0.0.0.0/0
There's also another file that loads all the ip_masq modules. I'm also
running a name server on my gateway. Could that cause a problem?
My gateway's running Debian 2.0 and has an internal 33.6 modem. It's
connected to the other box via coax ethernet.
I'll appreciate any help. Please reply by email also.
thanks in advance,
Eugene
