I've run the ppp groups for the last year and have not seen a post
regarding a problem exactly like yours, it does seem to be unique.
I've refrained from answering your newsgroup posts in hopes someone
else had a definitive answer. I don't have such an answer. One answer
you got was reasonable for most posts with similar symptoms but did not
quite fit what you described. It did suggest tcpdump to help solve the
problem which might be of real value - I've not used it, but understand
it's a powerful networking debug tool.
One thing missing from your posts are the appropriate lines from
/var/log/messages and /var/log/debug that show in considerable detail
what occurs when a pppd/chat connection is attempted. The connection
can fail in a lot of ways and it is not clear from your posts whether
the modem even succeeds in dialing the ISP number. You need to add the
pppd "debug" option to get messages in /var/log/debug that show what
happens during ppp negotiations. Sometimes the /etc/syslog..conf file
needs to be configured for the messages to go to this file. RedHat may
have other ideas about where these messages go, and I don't use RH.
(BTW RedHat has a tendency to muck with the ppp code as well as the
kernel code, if you bought support from them then you might see what
they have to say about your problem.)
Also missing are samples of the outputs from the ifconfig and route
commands, although since the configuration files in your email seem
correct they may not be significant for this problem. The version
of ppp can also be useful for some problems.
You mention that you compiled the kernel to use a CD burner. It might be
worthwhile to try using a stock kernel as a check on whether that kernel
or the CD burner is a factor. I also would try disconnecting the linux
box from the HUB to see whether things change.
As a last comment, in one post you said
The only way to establish _any_ ppp connectivity seems to be to use
the above-mentioned network configurator to trivialize ("remove")
the eth0 interface.
Even with this accomplished, the ppp0 interface remains unusably
unstable. Symptom and evidence: "pppload" shows _very_ high _outbound_
ppp traffic, saturating the interface. FixRoutes.sh _mitigates_
the problem _briefly_ .. until it resurfaces, at times and under
circumstances unpredictable to me. The connection will _remain_
unstable until the _entry_ _in_ _the_ _hosts_ _table_ containing
192.168.0.2 mjollnir
is removed with the RedHat tool.
This, together with the fact that a reboot restores some functionality,
suggests to me that there could be a hardware problem.
