After setting up IP Masquerading with ipchains on RedHat 6.0 (Hedwig), I
am no longer able to visit the web page on the linux machine. I plan on
using the linux box as a webserver. Is it possible to set up ip
masquerading and still use it as a webserver?
By the way, ftp and telnet are still fully operational.

Did you edit the 'C:\WINDOWS\hosts' file on your Win computer?
And Samba does not use encrypted passwords.
It could be changed, but it is easier to setup the Win computer.
Look for a file named 'Win95_PlainPassword.reg' on the Linux computer.
Add it to the win-registry (after a backup).

This destination address is the internal address of machine 2, is it not? If so,
why is the gateway set to use eith1, which is that to the external link?
Similar applies to the remaining routes.... these seem to be messed up.

Presumably this establishes node 100 on net2's internal net as a tunneling

Not sure about the tunneling side, but that above seems incorrect, even before
getting the tunelling happening. I'm relatively new to this also, so bear with
me.....

Subject: DHCP + 3C509B NIC ??
Date: Fri, 6 Aug 1999 02:32:54 -0500
Hello- I have installed two 3C509B cards in my RedHat 6.0 system. I have
configured them with the DOS utility to both have PnP Disabled and they have
separate IRQ's. Using the control-panel applet in Gnome I configured eth0
to use DHCP and activate at boot. I configured eth1 with a 192.168.x.x IP
address.
My problem is then when I connect eth0 to my cable modem it says on boot
that:
bringing up device eth0
FAILED: unable to determine IP information. FAILED.
After this if I run ifconfig I get only information for lo and eth1.
I KNOW my ISP uses DHCP, and I have heard of some who use it successfully
with this ISP. What is my problem. I have read the DHCP mini-HOWTO without
much luck. Am I being to vague, missing something obvious, or just stupid.
Why am I not getting a public IP address? Any help or suggestions would be
greatly appreciated. Thanks.

Hi Aaron,
I have a Teles ISDN card at home (Teles So 16.3 ISA) and I use SuSE
Linux 6.1. The quickest way I found to get ISDN working is to use KISDN:
It is a very convenient tool and install without any problems. Moreover
you do not have to worry at all about fiddling with some odd
configurations - it just works fine.
I even wrote a small section about KISDN on my homepage:
http://www.eco.rug.nl/medewerk/maier/Recreation/html/kisdn.htm
Good luck!

Seems like all I needed was a good site on explaining the workings of DNS.
But all I could find was the setup of DNS.

Have you tackled the 'encryption' issue? Section 4.4 on my web-page
In order to browse, you need a valid user-account on the Samba box.

Date: Fri, 6 Aug 1999 09:36:09 +0100
Have a look at www.dynip.com - thats what i use for a similar sort of
problem. I need to beable to access my ftp server and I too am on a
dynamic ip. using this all i have to do know is ftp
www.xxxxxxxx.dynip.com and it works great.
Alternativly I know of some people that have various scripts that ping a
host periodically so tha tit keeps traffic going down the line which
keeps the line up and thus keeping the same IP. I have also heard of
people setting up scripts to check for mail every minute or which is
supposed to have the same effect. There are loads of resources on the
web about this just do a search. I think theres a cable modem how-to
aswell.

Conversation: Cable modem dynamic IP
Subject: Cable modem dynamic IP
Hello,
Here in Sherbrooke, Quebec (small town) the local cable company is going
to be rolling out it's Internet-via-Cable-modem service.
I wanted to have the service installed at my home office. My home
office
would then ALWAYS be connected to the net.
I am a physician and have built a database on my server at my home
office.
I would like to connect to that server from my other office at a clinic.
My idea was as follows. Use clinic computer to connect to the internet,
and then enter my server at the home office and use it's database.
My problem is that the cable company says that they use dynamic IPs for
the cable modems' connection to the internet. This SEEMS to me to
prevent
me from entering my server via another connection to the internet.
Is there a way around this, without purchasing THEIR solution (a
COMMERCIAL access plan with FIXED IP address at much HIGHER rates)
Thanks very much

If you can't ping A from B then you may have an Ethernet problem. Try to
do a "tcpdump -i eth0". If you do not see packets going in&out then you
are not connected to the ISP LAN.
If you see packets then maybe the ISP router has some filtering on your
IP address and won't respond.
Hope this helps,

ping will tell you the response speed, which is similar for 10 and 100baseT.
setup samba (or nfs..) and tranfer a few megs over the network, then use
something like IpTraf to monitor speed...

Unplug the power to your cable modem.
Plug it back in.

Date: Thu, 5 Aug 1999 09:27:42 -0700
Two days ago, GTE installed a 384/384 SDSL modem. They then sent someone
from GTI (VOLT) to set up the net. He only knew how to do pump on RedHat,
and Windoze. My system is latest Slakware (linux-2.2.6). He said I was on my
own.
The first NIC (3c509) has a small LAN with Mac(s), W98(s),and NT(s). Local
networking and Samba working fine.
The second NIC (ether express 10/100) is module loaded to go to the net.
Configured and rebuilt kernel for packets/firewall/filter, as specified.
None of the dhclient.conf or dhcp.conf examples seem to show dynamic IP
address access. They seem to think the linux (as a router) has a fixed
address, which makes no sense. Everytime I run dhclient I get a "Protocol
failure:..." as shown in documentation. Looking at .config in /usr/src/linux
shows packets/firewall/filter all set=y. Yes, I did make modules, make
modules_install, and "lilo" after copying zImage to vmlinuz.
Downloaded ADSL HowTo. It also seems to assume fixed IP address for NIC.
Continuing to experiment/try/read, but anyone got a recipe??

Good to know, but I was not able to replicate the behaviour on my side.
I am using MSIE4.X and all my chrooted users remains chrooted. It's only
the non-chrooted users that are allowed to the root directory of the
server. Perhaps you would like to set up ftp only accounts, if that is
so, u might like to look into the FAQ of the particular FTP server that
you are using.
Anyway, the normal users are **allowed** to access the root and /etc
directory anyway, so if by using MSIE5, it's just a click or two away. I
do not see how this can be overcome except by using shadowed passwords.`
Just my 2 cents.

Subject: route command hangs
Date: Fri, 06 Aug 1999 01:50:15 -0700
Just trying to get a NE2000 compatible ethernet card to work. I've
checked all the settings with ifconfig and route, and everything is
set. There are no problems with the irqs or i/o addresses but when I
use route the command hangs for quite some time before it responds.
Plus I can't telnet or ping or anything, even though the card is
recognized at boot time and up and running with the correct ip address
and routing tables? Any guesses? I really think that the hangup in the
route command points to a problem, if I remove all the routes but the
loopback interface the command runs quickly.
