Subject: Detecting duplicate IP addresses in Linux
Date: Wed, 18 Aug 1999 16:09:36 GMT
A while ago I posted a message regarding duplicate IP address
detecting. I was kinda miffed at the fact that win boxen could do this
(at boot up) but there seemed to be no facility in Linux. I finally
found a (rather obvious) solution and thought I would post it to the
group so that others can find a ready answer.
All you gotta do is run a tcpdump command that is set to capture 1
packet where the IP address is mine but the MAC address is not.
note: the ifconfig command gives the MAC address
This should work even if you are on an ethernet switched environment
because eventually the dup ip host will send an ARP broadcast that
tcpdump should pick up.
of course, this will not work across a router but who the hell cares if
there's a dup ip across a router? This also will not work if you have a
NIC card that does not support horny mode.
I think that the way windowz does it is to do an ARP request and see if
anybody answers. I prefer that method because it's active. This method
is passive but it will work at any time, not just at bootup.
sample script:
while true
do
PACKET=$(tcpdump -e -c1 -i (Interface) src (interfaceIP) and not ether
src (interfaceMAC))
{
echo "Holy Crap! Somebody has my IP address!!!... Here's the packet:"
echo ${PACKET}
) | tee /dev/console | mail [EMAIL PROTECTED]

The only way, I found to solve this, was using unencrypted passwords under
win98.
This you can do, if you add an entry to you win98-registry:
\HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\VxD\VNETSUP
a DWORD-entry: "EnablePlainTextPassword"
and set the value to "1"
This should be enough, to get on your linux-box !
Hope it Helps

Linksys also makes a 10/100 autosense hub suitable for mixing
10bT and 100bTX on the same lan for less than $130 retail.

After the header text, you need two new-lines; your "echo" provides the
2nd one.

Subject: Securing Linux NFS
Date: 18 Aug 1999 16:48:48 GMT
I am looking for input on securing NFS from users with laptops that can
connect to the network ( disconnect a valid computer, set IP to a valid
one, and be able to mount any disk from the server ).
As things stand now, anybody with a physical access to a network can
grab any file they want from the server, and I suspect many people don't
even realize how easy it is to do - since most of the attacks on networks
are in fact internal, firewalls and such are not much of help.
I have tried to pe-load arp table on a Linux server to force MAC to be
fixed ( ie. an attacker would have to assign both IP and MAC ), but Linux
allows connection even if the host MACs don't match - I suspect there
has to be a way ( short of patching the kernel to force this ). Mind you,
you don't get much of a security but it is better than noting :)
I have seen some talk about CFS and Linux, but that does not look like it
is solid as yet and ready for a production system with few thousand users -
has anyone used CFS on a production system ?
Kerberos is suppose to allow for increased NFS security - is anyone out there
running Linux+Kerberos+NFS - any comments ?
Thanks,
Peter

Date: Tue, 17 Aug 1999 20:54:39 +0200
Hello Omega (a Alias is unfriendly to use in NGs!!!),
vise versa?? What's that.
Well to network with a Win95 machine you have to have 2 Netcards (one in
the Win95 machine and one in the Linux box. And don't forget the cable
between the boxes!!!!
Now to the software:
I hope you know how to set up a network in Win95!!! If not, tell me.
Run Netconfig to configure the settings (hostname, IP,..)
Most of the Network cards are NE2000 compatible. So go to
lib/modules/2.x.xx/net
and do a
insmod ne.o io=0xnnn
nnn stands for the I/O Base Address of your card. Normally 300!!
If you havn't got a NE2000 (+) or NE1000 compatible card, search the
matching .o file out of /lib/modules/2.x.xx/net and do a insmod on this one.
(Without the io parameter) if it tells you that the ethernet device has been
found, it's defined as eth0 if it is the first card.
Voil�. The first step is done. Now add the insmod line to you bootup
file.
After that, you should be able to ping to your Windows box and back.
(Make sure that TCP/IP is installed on the Windows PC, too.)
You can do a Telnet from your Windows PC to your Linux PC, now, too.
To connect a network drive via the Windows explorer to the Linux PC
you need samba running on your Linux box (www.samba.org).
Now you can connect from your Windows box to the linux box via the
explorer and from Linux to the Windows box via smbmount (For more info's
about smbmount, type man smbmount).
Hope this helps,
Freddy

The IP stuff is already on the win box, configured to point at the ISP.
That's my problem. i know how to setup a linux firewall, provider there
is a network on either side. perhaps, in the case, 'firewall' is a poor
choice of words. here's what i want to do:
plug the cable modem into a NIC on the linux box.
plug the win box into a 2nd NIC on the linux box without subnetting the
win box.
pass packets from the linux box to the win box.
hopefully, the linux box can filter the packets. if not, maybe i can at
least close the route to the win box when it is not in use.
thanks.

optimally, I'd pay the $20 IF I could get source. ie, I don't mind at
all paying for somone's effort, but when things break (and it appears
they do, sometimes, with oss) then I want to be able to fix it.
otoh, I understand that they CANNOT release source since they had to
sign an NDA to get specs on some cards. one card that I own and NEED
drivers for is only NDA and even then, the oss guys aren't really on
the ball about delivering high quality and FULL FUNCTIONAL drivers for
it (the card is a sonorus studi/o - which has been claiming linux
support for well over a year now, but still does not have multichannel
i/o working).
so I have mixed feelings about oss. if they would do a complete job
and in a timely manner, I'd support them. but since their
implementation for the card I need is far from complete, I'll hold
onto my money. vote with your dollars, I always say.

I posted the original question, so now I'm posting the solution :)
To whoever posted that the 2.2.6 Kernel contained support for the 8139
chipset, thank you! That was what was going wrong. Trying to load a
module that's already in the kernel (as part of the source) does result
in a "device or resource is busy" message.
Knowing that, we can use the "ifconfig" command "ifconfig eth0 up
xxx.xxx.xxx.xxx", where the x's are your ip address. The catch though,
is that the device "eth0" (/dev/eth0) doesn't exist in this particular
distribution anymore. In the /dev directory by typing "man MAKEDEV",
you can find this out. You are also given the location /proc/net as
the place to find a file called "dev". This file tells you the alias
you can use for the network card. On my system, it ended up
being "lo". "ifconfig lo up xxx.xxx.xxx.xxx", using x as the ip
address, and the card is up and running.
To test the functionality of the card, I used "ping" to test my
connection with my other pcs. I can ping both of my W98 pcs, but not
the other way. That is something to look into next.
For those looking to learn SAMBA, I recommend "Teach yourself SAMBA in
24 Hours", by SAMS publishers. It's a very good book, and it uses
plain english to explain the process of setting up different parts of
SAMBA, as well as making W9x/NT boxes see Linux shares.
Again, my thanks to everyone who contributed an idea to this problem.

Hi, (pardon my lack of CAPS)
i have my linux box with 2 ethernet cards with eth0 on a cable modem with
dhcp and eth1 as my gateway device.
when i look at the logs it says that eth0 is initialized in promiscuous
mode. also when i booted up my win box without changing the settings (eg:
obtain ip address automatically) it got its OWN ip address. this should
not happen at all. This has not happened before. It is freaking me out.
a few questions:
-why is eth0 philandering about?
-what does it mean?
-how do I fix it?
-what will my cable modem people say when there are two requests for two
different ip address while one ip address is still alive (by which i mean
that it is still under lease)
thanks a lot.

Yes you will gain performance. Think about how a coax network works. When
one machine is talking on the coax, all of the other machines have to
listen before they can say anything. With a twisted pair and hub setup,
more machines can talk at once, and the talking can be in both directions.
Much nicer.

Some hubs are better at handling collisions than others. I am not sure
which ones are better than others, but in this sort of networking area, you
usually get what you pay for.

If you can afford it, go for the PCI NIC's that support 10/100 connections.
You don't have to get a 100base hub immediately, but look at the investment
of the 10/100 NICs as being an investment for later. You will very likely
be expanding in the future, and when you do you may want to go to faster
network speeds. If you already have 10/100 cards in all of the older
systems, it will be very easy to convert the entire LAN to 100base just by
changing out the hub.

Date: Wed, 18 Aug 1999 13:07:05 -0400
I'm setting up a small network and I'm having some problems with
sendmail. Turns out its because there are some DNS queries that are not
working.
Setup is as such - Gateway machine is running a caching only name
service setup as per the how-to. Works great on THAT machine.
Now, I want to have my mailservice machine query the gateway for DNS
info. This is where my headaches begin.
I believe I have a configuration problem on my mailservice machine as
when I type in 'nslookup' on mailservice I get a
[root@gabriel /root]# nslookup
*** Can't find server name for address 10.0.0.1: Non-existent
host/domain
*** Default servers are not available
[root@gabriel /root]#
FYI, my gateway machine is 10.0.0.1 and my mailservice machine is
10.0.0.10. Both are running RH 6.
On the gateway machine, the resolv.conf file is properly configured
(otherwise my DNS queries on that machine would fail).
My question is, how should the mailservice machine be configured such
that it can properly query gateway for DNS info?
I've mucked about with the resolv.conf file on mailservice, and the
/etc/sysconfig/network lists the following:
[root@gabriel sysconfig]# more network
NETWORKING=yes
FORWARD_IPV4=false
HOSTNAME=gabriel.redeem.org
DOMAINNAME=redeem.org
GATEWAY=10.0.0.1
GATEWAYDEV=eth0
[root@gabriel sysconfig]#
redeem.org is my 'internal name'.
Thanks folks,
