Allright, I think this is going to be basically the last step of my
journey. I've got a pulse now but the problem is that my connection
seems to be dropping rcvd packets.
I've altered my options file heavily and here is a current copy:
/dev/modem
noipdefault
crtscts
defaultroute
lock
debug
kdebug 7
#noaccomp
#nopcomp
#passive
lcp-max-configure 25
#lcp-max-failure 15
#lcp-max-terminate 15
#lcp-restart 6
#lcp-echo-interval 1
maxconnect 200
mtu 552
mru 552
I've been constantly altering the values and commenting in an attempt
to get a working connection.
I've removed the pppd/chat command and added in an automated dialer
that brings me directly to the ppp session. Here is a log from the
most successful pppd connection I have gotten yet:
May 28 16:05:52 Zeos pppd[871]: pppd 2.3.7 started by root, uid 0

I've been constantly tweaking lcp-max-configure in an attempt to get
further into the ConfReq. Judging from the time stamps of most
sessions, it would seem that I'm losing a ton of rcvd LCP packets
(modem init strings?). If anyone could help me somehow clear up the
link I think I'll be in business.

hmm... not sure this is such a good idea... a compiled kernel image is
custom built to the particular system -- meaning it should include all
regularly used hardware, and as little else as practical. In theory,
you could get a kernel that would work, but it wouldn't be what you want
to do.
However, setting up IP masquerading is very straightforward, and will
work with a stock RedHat 6.0 install very easily.
You need to read the IP Masquerade Mini HOWTO:
http://metalab.unc.edu/linux/HOWTO/mini/IP-Masquerade.html
Basically, use "make menuconfig" from /usr/src/linux/ and be sure to
compile the dozen or so things they say you should have:
http://metalab.unc.edu/linux/HOWTO/mini/IP-Masquerade-3.html#ss3.1
do make bzImage ; make modules ; make modules_install
Reboot w/ new kernel in place, then execute some ipchains commands
(covered in the HOWTO).
That's all there is to it.

I am running Redhat 6.0 and am having some problems connecting to my ISP
thru Minicom.
I'm new to this so I'm not sure what it all means, but /dev/modem is a
symlink to /dev/ttyS1 and shows owner root group root and permissions
rwx rwx rwx. /dev/ttyS1 shows owner root group tty and permissions
rw- rw- and ---.
For what it's worth, I am able to establish a ppp connection to my ISP
using either the Usernet utility or from the command line. If anyone
could point me in the right direction on how to establish one using
Minicom, I'd appreciate it.
Thanks

Yup. Win95 and SuSE Linux.

This is exactly what is happening in my case. I am able to network with
the other Win95 box, so I know the hardware is working.

This is one major reason why I don't want to do windows anymore. Even if
Linux is a pain in the a** to learn, at least I am master of my machine. I
want to know what my interrupts are, and don't want any "Wizard" playing
with my hardware or installing stuff without my knowledge or permission.

The card came installed with the machine. Does 3com have this
configuration program on their website? BTW, from all the stuff I have been
hearing about 3 com and (especially) the 3c509 in this NG, 3com should start
supporting their stuff under Linux or risk loosing a lot of business.

Well, given that you cannot access MS software patches from their website
using netscape, (you must use MS-IE for this) I would put absolutely nothing
past them. I am not a firm beliver in conspiracy theories, but given the
stuff that has come out of the DOJ trial in the U.S. there is very little
that I now belive M$ will not do.

Well, thanks anyway for responding to my posting. I very much appreciate
the insight, and will be a major eye opener if this is in fact happening.
It certainly seems to be plausable. I haven't got my eth0 working again
yet, since I have had bigger fish to fry for the last few days. Now that my
KDE upgrade and diald seems to be up and running properly, I will look at
eth0 again. I wish there was a way to stop windows from screwing with my
hardware settings.

mgetty (the recommended getty to use for such purposes) has a really
neat feature (which the writer of mgetty does not like-- get another
phone line he says) in which you can ask mgetty to not answer the phone
on thefirst set of rings. You dial in, hang up, and then dial in again
in a window between 20-45 sec after the first hangup, and now the mgetty
will answer the phone. The first time you can let it just ring once so
your answering machine does not answer and the second time you can have
mgetty answer on the firstor second ring, so again your answering
machine stays off the line. It works really well The only time you would
be in trouble if the same person phoned you twice in a row withing that
time window.
Note that if you have CallerID on your phone line ( and your modem
suports it) then that second call must also come from the same phone
number as te first for mgetty to answer the phone. (again stops problems
with two diffeent people phoning you within 40 seconds of each other.)
(It is called
ringback on
)
I have it set up so that during the day the ringback is on and at night
it is off, so that mgetty answers on teh first set of rings.

What are you really trying to do?
I use tar and bzip2.
cpio might come in handy for the device files.
Linux-Linux likes NFS and Linux-Windoze likes SAMBA.
Of course just about anything is possible if you know what you want to
do.
I don't think that windoze is going to know anything about e2fs unless
your thinking to run linux on vfat. So guess that means you will need
linux up to restore the linux partition. There are a couple of
attachments at the bottom of this message showing dual boot
configurations I like to use here. You Don't even need a linux partion
if you don't want it.

I am not an expert but you need more ipchains commands.
I don't really know what are the default settings for all the things
you did not set (policies for the chains as an example). Your rules
should follow a logical plan. You will be inspired by the following:
=========== cut here ==============
/sbin/modprobe ip_masq_ftp
# Supports the masquerading of RealAudio over UDP. Without this
module,
# RealAudio WILL function but in TCP mode. This can cause a
reduction
# in sound quality
#
/sbin/modprobe ip_masq_raudio
# Supports the masquerading of IRC DCC file transfers
#
/sbin/modprobe ip_masq_irc
#
# setup IP packet Accounting and Forwarding
#
# Flush all commands
ipchains -F
# this enables the packet conversion/routing
ipchains -A forward -j MASQ -s 192.42.172.0/24 -d 0.0.0.0/0
#Aggrandit les timeouts
ipchains -M -S 7200 10 60
#this will block netbios
ipchains -A input -j DENY -p tcp -s 0.0.0.0/0 137:139 -d 0.0.0.0/0
ipchains -A input -j DENY -p udp -s 0.0.0.0/0 137:139 -d 0.0.0.0/0
#MINIMISE LE DELAI POUR HTTP ET TELNET
ipchains -A output -p TCP -d 0.0.0.0 80 -t 0x01 0x10
ipchains -A output -p TCP -d 0.0.0.0 telnet -t 0x01 0x10
#Redirige tout les trafic de X pour platon (display 0)
/usr/sbin/ipmasqadm portfw -a -P tcp -L 207.61.102.239 80 -R
192.42.172.2 80
==========
where 192.42.172.0 is the local subnet
and 207.61.102.239 was my ip address.
