Re: tlug: PPP&RH5.0 (was: Infoworld Review)

["A.Tomita,Jr." <alberto@example.com>]

After two days and a sleepless night wrestling with RedHat 5.0
I finally got a working PPP setup.

As the kernel debug messages revealed, the problem was indeed
related to bad PPP packets, and had nothing to do with routing.

When installing RH5.0, I had also upgraded the pppd to version
2.3.3 (ftp'ed from redhat-5.0/updates/i386/ppp-2.3.3-2.i386.rpm).
According to some articles I found at comp.protocols.ppp, it happens
that this version apparently has problems negotiating with CISCO
routers (my ISP is probably using these).

The error message was:
> Feb  4 02:28:29 neutron kernel: ppp: frame with bad fcs, excess = b819

These frames were corrupted due to the wrong settings that were
negotiated between ppp-2.3.3 and the router, causing frame checksum
(fcs) errors. Including the directive "asyncmap 0" in /etc/ppp/options
solved everything.

As for the traceroute complaining about multiple interfaces and
defaulting to eth0, I learned that I should use "traceroute -i ppp0".
