Hello,
I have 4 machines on my lan they are all networked thru my
hub Linux box hs the ppp connection to the Internet along with being
connected to my hub on the Lan i am presently reading the NET-3 how to

file and where is that file located or do i just type it in on the
command line.
root# route add -net 192.168.1.0 netmask 255.255.255.0 eth0

That's only a web page redirector! Bleagh. Try www.ddns.org for a free
dynamic dns service. There's also www.dynip.com who charge you something
like $40 American a year but they have a free 30-day trial. Also some of
the guys from Monolith are attempting to get a similair system off the
ground but it's still in development stage and they need funds.

This is a hradware problem with Compaqs. The new generation Deskpros does
the same. Th eproblem comes from the fact that it has a strange BIOS system.
NT and Novell even provide special drivers for Compaqs.

It depends on what you use in Exchange, if you want Linux to run as a SMTP
server with POP3 and IMAP4 client protocolls, than it can be done.
But a X400 connector isn't there yet (well probably is on another unix
platform so you might port it). SMTP/ESMTP is a standard that came out of
the unix world just like POP3 and IMAP

I'm looking for *C* sourcecode (for Linux) that RE-calculates
the IP and ICMP packet checksums after modification.

Anyone?

Subject: How do I reinstall Linux to a new file system from a running Linux system?
Date: Thu, 14 Jan 1999 16:21:48 GMT
I already have Linux up and running on /dev/hda4. My swap is /dev/hda3 and
previously I had Windows NT server on /dev/hda2. /dev/hda1 is my OS2 boot
loader. So I love Linux, it does everything (and better) then NT server did
(nanny nanny poo poo Billy boy) so I nuked the NT server partition and made
another ext2 Linux partition on /hda2. I would like to be able to make /hda2
my new Linux system and use /hda4 for user files, games, etc. (non Linux
system stuff). Right now, /hda2 is empty. So, how do I get Linux over to
/hda2??
I looked into cp, but the problem is that it doesn't seem to copy files that
have hard/symbolic links to them properly. At least it didn't seem to work
when I tried to. Also, it barfs when trying to copy /dev over and I assume it
probably will have a heart attack with /proc. Anyway, I thought I could
simply copy all the Linux system directories over to /hda2, reconfigure lilo
to point to it, and then boot. Doesn't look like I can easily do this.
Another option I was thinking about, is doing a network install if this is
possible? I currently have Linux setup with an ISDN high speed Internet
connection (using pppd). My flavour of Linus is Red Hat 5.2 using kernel
2.1.130 (needed some support in this kernel not available 2.0.36). Is there a
way I can run the same Red Hat install program that I originally did and ftp
all the files from sunsite over to /hda2 from my running system? I can't
reboot from the floppy install disks to do this, because the ISDN support
isn't there unless my current Linux system is running (I originally did this
by installing the ISDN in a Windoze machine and using ftp through a proxy, but
I don't want to disconnect the device and do this again).
There has to be an easier way?
Also, I use partition magic (installed in /dev/hdb1 - second IDE drive) to set
this stuff up originally. It works great and allows me to boot any OS. It
also allows me to resize partitions - safely. Is there any advantage to
having my swap partition as /hda3, or should I try to move it physically to
some other part of the disk? ie: move /hda4 to where /hda3 is and
visa-versa putting the swap partition at the end of the disk
partition space. Probably, I should just leave it as it is...

I'm pretty sure NT SP4's DHCP server is broken.
It don't talk to dhcpcd clients, though SP3 did.
Check the SP # of your server.

Userland, with packet sockets.
With packet sockets the MAC layer *IS* accessible. I wrote a program
that puts raw ethernet packets on the wire, with random MAC addresses
and it works perfect. Now, I want to do this with "real" mac addresses...
I "found" a solution though, but it's far from perfect. Look in
/proc/net/arp, there
you will find the ARP cache for the kernel. Combined with a cache in the C
program this will have to do.

There's a lot missing here. If it's the same as below, then it's OK
to omit it. But it would have been more comforting if you had started
from the beginning and then chopped it off when it was clear that pppd
was doing a monologue.

Pppd is talking to itself again at this point regardless of what happened
previously. It does this sometimes when the connection scripts fail
and it can't talk to the ISP.

Simpler is better:
exec /usr/sbin/pppd debug lock modem crtscts /dev/ttyS2 115200 \
asyncmap 00000000 noipdefault defaultroute connect $DIALER_SCRIPT
I would drop the <escape FF> regardless, it actually causes trouble
with some ISP ppp implementations. The asyncmap 0 provides the best
throughput but sometimes, again depending on the ISP implementation,
you have to use something else, a0000 or 20a0000 being the most common.

OK ATDT$TELEPHONE \
CONNECT '\c' \

ogin:--ogin: $ACCOUNT \
assword: $PASSWORD
In order for this script to work the expect send login sequence must
be correct and the ISP cannot be expecting PAP or CHAP authentication.
Since each ISP has it's own peculiarities this script may fail also,
but I believe it has a good chance of succeeding.
If you really don't want to try this then at least try replacing
<CONNECT ''> with <CONNECT '\c'> .
