Subject: IPChains and IPMasquerading
Date: Sat, 17 Jul 1999 08:49:59 -0700
I have read many differant instructions on IPChains and Masquerading,
and am still confused. Some talk about adding a line to the rc.local
file, others don't. The rc.local file is a script, so where in there
would I insert the line to run ipchains? Another talks about writing a
ipchains script, but leaves out what folder to put it in and what name
to call it. I have the how-to printed but shoot, that is so huge, isn't
there an easy way, some simple instructions that don't leave out parts?
I just have 4 pc's connected via a hub (peer to peer) and a isdn
terminal adapter (not router) on one of the pc's. Also, if this works
for the linux machines to access the net through the one, can win98
machines also access the net through the linux box? And can each machine
tell the TA to dial and disconnect? or does that have to be done on the
one pc?

I recently installed RH Linux 6.0 on a 486-100mhz 1.2G PC. That's all it
has on it. I installed it with RH's workstation class install. I
temporarily hooked up a CDrom from another PC I have on my home LAN network.
After installation I took the CDrom off of the newly built Linux box and put
it back into my Win95 box. My logic was that I could use the Win95 CDrom
unit to simply ftp the files to the Linux box. My problem lies in the fact
that I cannot get my Win95 to successfully ftp to my Linux PC. What is the
best way to gain access to my CDrom unit on the Win95 machine. Remember, I
don't have the ability to copy any files directly to the Linux box.
Thanks for your help,
Wayne Larimore

Just got it running myself. A couple of things:
The Cisco doesn't make my DLink 530TX autoswitch to 10Mb, I have to do that by
hand with the media switch on ifconfig.
dhcpcd is not set to run automagically, even when you enable DHCP in the
install. I had to add it to my rc.local file.
The 3Com they sent me worked fine, and then I converted over to the DLink.
I'll probably go back to the 3Com for the modem and the Dlink for my intranet
at home.
So, basically, you install the NIC, set it to use DHCP for configure, and make
sure it is set to run at 10Mb with ifconfig. If dhcpcd isn't autorunning, you
can just su - to root and run it yourself.

Well I've got static address from @Home and have switched many different
network cards around with no problem. I've also plugged the cable modem
directly into my hub (via crossover). When the interface that the modem
plugs into changes, it usually goes offline shortly (less than 30 secs)
for a network configuration, then works fine. (I've got a Com21 2000
cable modem.)

Subject: Delayed Telnet Connection
Date: Sun, 18 Jul 1999 04:55:46 GMT
Just installed RH 6 onto a 486/50 with a single NIC card. I can ping, ftp,
and http into the box with no problem. But, establishing a telnet session
takes over a minute. I've been reading and seem to think that this has
something to do with reverse lookups.
I have since added the IP addresses of the clients to the /etc/hosts file.
Connection time is damn near instaneous. Obviously, on an intranet, I'll
know the valid IP addresses. But, I'd rather not type them all in.
How can stop the telnet daemon from doing reverse lookups or solve the
problem I'm experiencing without my having to add all the IP addresses to
/etc/hosts?
Do I need to set up my own DNS server to solve the problem?
Thanks,
Charles

: the way i understand it the modem has to have the same nic card used

That turns out not to be the case. Until I got my second NIC
for the firewall machine, I ran the cable modem into the "daisy chain"
port of my hub, and it was perfectly happy to talk to the NIC I had.
The networking was a bitch, but a bit of tinkering with the routing,
I got the firewall to route my packets to local IP addresses and
to the cable-assigned IP both to eth0.
So, in my experience, the modem will work via a hub. "They" used to say
that in a stage whisper only, and only if you get the installers in a
corner to talk shop. But now, that's the recommended mode of operation
if they sell you additional IP addresses, as @home is now starting to do.

It sounds like what you really want is the Berkeley Packet Filter [BPF]
and a packet analysis tool like tcpdump. BPF support should already be
compiled into your kernel if you're using ipchains, and tcpdump should
be available in RPM form wherever you do your shopping.

Unless "the other end" happens to have a routable IP address [anything
in 192.168/16 is *not* routable], this isn't going to do you much good.
If any of your firewall's upstream gateways don't "believe" the forged
address, it isn't going to do you much good. I'm not sure exactly what
you're trying to accomplish here.

George-
The Interrupt 255 reported in ifconfig combined with the message "The PCI
BIOS has not enabled the device at 0/80!" means you probably have a plug n
pray problem. I'd solve these by scrounging a DOS boot disk and running the
configuration program that typically comes with the NIC on the floppy to
"hard config" the board resources to known addresses and interrupt. I'd
also run the diags...just to make sure.

Hi:
I have looked at the examples in
http://www.sfu.ca/~yzhang/linux/samba/index.html
http://home.talkcity.com/MigrationPath/maguai/samba.html
they are kinda different from one and the other , especially the smb.conf
files!!! I thought they should be much the same...
I followed the Simpsons example but Homer never shows up in Bart's network
neighbourhood. I could ping each other as well as seeing the Apache page
on Homer through Bart (only IP address if I type http://homer it says host
not found..) if I can ping Bart's IP from Homer and can telnet to Homer
from Bart I guess basically there is a connection.. just that it is not
finished. I thought my workgroup was wrong in syntax but I check it to
"Workgroup" after failed in "WORKGROUP" or "workgroup"... so I think the
matching workgroup name fact should not be there.
Also is it true that after finishing the samba set up Bart can use the
IE to browse the net too?
I heard that you can set up so that if you have a cable modem line connect
to eth0 of the linux server, the other clients can also connect to the net
without another line. Does anyone have a more detail example of how to
set it up like that? Or if anyone know any resource or doc that I can read
more about it.
Just in case I miss the reply , which I really hope not.. please send reply

Not really an ipchains problem. The people who wrote ipchains had good
intentions but I do get the impression they were somewhat braindamaged
... anyhow it sounds like you want to do port redirection. The utility I
use for that is redir, but you might be able to use ipportfw as well.
The confusion (for me anyhow) comes from the fact that you can reroute a
packet so:
-> xxx.xxx.xxx.xxx 80
-> fi.re.wa.ll 8080
but not:
-> fi.re.wa.ll 80
-> behind.fire.wall 80

Not certain, but for me it DID solve the problem. If you are telnetting
to the same addresses all the time, you might get away with adding the
info to /etc/resolv.conf (make sure your DHCP doesn't replace it tho ;)

Hi!
I have a linux RH6 firewall setup on a telus (Calgary) ADSL hookup. While
digging deep in the accounting setup I noticed that tcpdump shows tons of
incoming packets, all alike:
>tcpdump -i eth0
...
00:56:34.085028 10:1f:8d:c8:64:0 sap 80 > 0:0:0:80:0:0 sap 14 I
(s=0,r=0,C) len=42
50bd f3b8 5480 0802 0014 0002 000f 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000
...
Does anyone know what they are and what I can do to clock them out in the
firewall input rules (ipchains)?
Thx,
Rudolf

Terry,
Try putting the following in your rc.local file:
route add default gw ppp0
You can just tell it the device without needing the IP # . Good luck,

Y.C.-
Most PCs have a BIOS configuration that enables the machine to boot with
keyboard errors. Set it to allow booting with keyboard errors, yank the
keyboard off (and the monitor too while you're at it) and reboot. PCs will
not recognize the keyboard after booting so even if someone comes along and
plugs one in they will still have to reboot the machine to use it.
