Geez, you have a sniffer, and you're asking US for help? Sounds like
you have everything you need in order to figure this out. :)
The machine is sending ARP requests, but it's not getting any ARP
replies from the other machine. There's only one reason I can think of
that that would happen: The other machine can't hear the request! Does
this happen in the other direction, too? Does the other machine send
ARP requests, and the first machine doesn't respond? Does the sniffer
hear both machines? Why would the sniffer be able to hear what the two
machines can't hear?
On the surface it really sounds like a cabling problem.

As a last-ditch effort, you could try hard-coding the other machine's
address into the arp table with "arp -s", but there shouldn't be any
need to do that. I'd be surprised if it works.

If the interface was configured with "-arp", that would cause it to not
negotiate ARP, but I can't belive you would set it up that way. :)
The default should be to ask and answer ARP requests.

I have samba up and running, and everything worked fine before I
upgraded from RH5.0 to 5.2 . It did change the smb.conf file, but I
modified it to match my old one. I have a feeling I missed some
config file somewhere though. I'll check out that site, thanks. maybe
it is the sharing part. might be what I missed.
thank you.

Can linux be setup as that gateway that picks the connection based on bandwidth
available? This would be very useful to me. If you can please give some urls
so I can read up on this subject. Thanks.

Hi,
I'm trying to understand the Linux sources (too much free time on my
hands see...) and in AF_INET.C, I found a function called autobind(), from
what I know, no program in the Linux source tree calls it, so who/what calls
autobind() and why?
If this is the wrong NG, sorry, please point me to the right one.
Thanks in advance,

Ok, so I decided to go play around with it just now. (it usually required
rebooting to make sure I was testing from scratch) Here is the order of what
I've set my startup scripts to do to get dhcpcd working in 2.2 on my Slackware
3.4 system:
#Begin /etc/rc.d/rc.inet1
HOSTNAME=`cat /etc/HOSTNAME`
#Just my local loopback device stuff
/sbin/ifconfig lo 127.0.0.1
/sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo
#I don't know if I need both of these, but it's what I did
#when testing, so I did this anyways.
/sbin/ifconfig eth0 0.0.0.0
/sbin/ifconfig eth0 up
#end /etc/rc.d/rc.inet1
Then, at the end of /etc/rc.d/rc.inet2, I run /etc/rc.d/rc.dhcp in the
background:
/etc/rc.d/rc.dhcp &
#Begin /etc/rc.d/rc.dhcp
NET=/usr/sbin
rm /etc/dhcp/dhcpcd-eth0.cache #otherwise it requests the old IP address
#The dhcp server doesn't seem to like that ???
while ! /usr/sbin/dhcpcd #loop until dhcpcd is successful
do
echo nothing > /dev/null
done
#put the rest of your internet related stuff here, including
#stuff to put your IP address into /etc/hosts, if you want, or whatever.
#end /etc/rc.d/rc.dhcp
Well, I wouldn't say it's been extensively tested, but I rebooted three
times, just to try it, and it worked every time. I believe dhcpcd failed the
first time every reboot, but then worked on the second time through the while
loop, so it was being consistant.

Madge has a driver for their PCI cards. The only ISA cards that work
are the Madge blue cards that exactly emulate the IBM ISA cards. You
need to contact Madge directly to get the drivers.

Add a keepup line to your diald.conf - see the man page for the syntax but
it should look something like:
keepup any any 120
where 120 is the idle timeout.

Moreover there is a security reason not to put the current directory "." in
the path of the system administrator, and is to avoid that some hacker,
disseminating in the public writable directories replacements of normal
commands, modified to grant him access to the system (like replacing the
command "ls" with one that issues the original command and also sends by
e-mail the password file or even worst reconfigures it adding an extra
superuser) might get its command executed by mistake by the root user.
In fact the /bin directory should be writable only by root. Avoiding to put
"." in the root path grants the superuser that all the system commands that he
executes are the original/controlled commands stored in such directory and in
other equally secure and not hacked replacements.

I haven't used leafnode since about v1.5 but I think fetch

Your newsreader will talk to leafnode through the loopback

or the loopback address 127.0.0.1

I believe the 2.2 kernel will support using a serial port as the console,
allowing you to cable it to another machine and use a terminal emulator
for booting etc.
There are also patches for 2.0 kernels to use a serial console, but I
could never get them to work quite as well as I wanted.

Subject: Big Networking Situation giving me headaches...
Date: Fri, 5 Feb 1999 05:41:05 -0500
I've managed to bumble my way through (mostly) setting up Linux and my
Win98 box to talk to each other, and I can get the Linux box on the net,
so I'm not totally clueless, but I'm not a MCSE/CNE either, so I'm really
out of my element on this one...
I've got a total of 6 computers to set up...
2 Linux boxes, 4 Win 95/98 boxes. Not such a big deal. But, there's
also the T-1 to consider...
The ISP is assigning us 2 Static IP's. Each Linux box will run a set of
servers, (web, pop, etc.) for two separate domain names. Call them
Server A and B. These are InterNic registered and should be available to
the world. Each Linux box will also have 2 Windoze clients, call them
Clients A1, A2, B1 and B2, which don't need to be visible to the outside
world, but need to get out. And I'd like all 6 boxes to talk to each
other, so that for example, one person on Client A1, can play Quake with
a person on B1, without going over the Internet... Oh yeah, adding to
the confusion, there's only one connection to the T-1. One physical
plug. Two computers... Hmm...
How the heck do I set all this up? Here is my best guess...
Put 2 NICs in each of the Linux boxes. Set them up so that one has the
IP address the ISP gives us, and one in the internal 192.168.* network...
If I just plug all of these wires, 8 from the computer, and one from the
wall with the T-1 into a hub will everything sort itself out, as long as
the routes, gateways, etc are set up right? Basically give the Windows
boxes addresses in the 192.168 domain, tell them that their gateways are
their respective servers, and that should be it, right? I just want to
make sure that the Windows boxes don't try to resolve any Internet stuff
directly, because the ISP charges by the IP of the computer accessing the
Internet. So as long as the Windows boxes go through the servers, I'll
only be charged for two computers worth of access, as opposed to 6
computers worth of charges.
AAK! This is driving me batty, just thinking about it. Somebody please
give me some guidance...
