You can get RedHat every bit as cheap as Debian; RedHat makes their
distributions available via FTP for free, just like Debian, and you can
buy them for $2 or whatever from CheapBytes, etc., just like Debian.
The $50 RedHat comes with some commercial software that obviously
doesn't come with the CheapBytes or ftp-based dists, but I've never used
it anyway. And it has a printed manual, which you probably won't need
if you've installed Linux before. And it has support for some amount of
time, but if you have USENET access you'll probably not use that either.
I used to use RedHat and it's a nice dist, but I've recently switched to
Debian and don't see myself going back, mainly because while RPM is
nice, the RedHat site is a mess. I could never figure out where to find
the updates to packages I wanted: the RedHat FTP site is split by
release and I'd start with my 5.0 directory, then try the 5.1, then the
5.2, then there were the "contrib" directories, etc. etc. The site was
slow and I could just never find anything.
I much prefer Debian, where everything is in one place, simple to find,
relatively up-to-date, etc. RH does have some handy admin tools
(printer setup, etc.) but for me, Debian is the better system.
Obviously YMMV.
My $0.02.

Tom,
This is really a FAQ. This is asked at least 5 times a week. Any reasonable
search on deja-news
would have turned up a bunch of answers. Some might even be right :^)
from memory (since I do not allow root telnet) is to look at /etc/sercuretty
and add the pty's that root can use.

I've done that with several network functions on Red Hat and

The problem is Red Hat has added a complex, undocumented layer
of cruft between you and the software you are trying to set up.
If you bought official Red Hat with the blue paperback, you're
entitled to phone support. Call them and get them to walk
you through it. They owe you that; it's why you paid $30-$50
instead of $3.

Ignore the Red Hat GUI setup stuff. Recent Red Hat comes with BIND-8
which works fine. Just set it up according to the BIND Operations
Guide available from http://www.isc.org/bind.html and the Real
Documentation at http://www.isc.org/bind8/index.html
instead of trying to play MS-Control Panel.

What matters is whether you have the CardBus version of the card or the
old pcmcia 16-bit version. The CardBus version isn't supported yet, but the
other one does work. I'm not certain of the model numbers, but I think the
CardBus version is a RBEM... and the other is an REM... Even on the REM
version, there are problems with 10M Ethernet which seem to vary from
card to card.
There are people working on the driver for the CardBus version. I'm on the
wrong computer right now or I'd point you at the web site where this is
discussed - but that wouldn't do you much good since there is no driver yet.

Hello,
has anyone an idea how to mirror an nt4.0 server on a linux-box? i need it
to prepare the replacement of this nt-server. this mirroring is just for two
weeks (in a huge multi-user area) to have two redundant servers, because of
several reboots on each machine. both should detect the reboot of the other
machine and take over the fileserver-tasks with the latest version of data
.. i know, it s not an easy job .. but if anyone can give me some hints i d

Here's what's happening:
First let's define some things. Let's call the .55 interface eth0 and the .56
eth1.
Your routing is setup to access your network through only one of your nics, in
this case eth0.
When you put your machine out on "the world" you will have your subnet (possibly
192.168.1.x) on eth0 and a default (0.0.0.0) on eth1.

You were on the right track to test it before you put it into production.
Here's a way to test:
Put your nics on separate subnets:
make eth0 192.168.0.1
make eth1 192.168.1.1
It doesn't have to be these addresses exactly, just put em on different
subnets. If you want to test it from another machine, make sure it's routing is
setup to access 192.168.x.x instead of 192.168.0.x otherwise it won't see
anything but what's in the 192.168.0.x subnet. If you're using 192.168.0.x on
your normal lan, use something like 192.168.3.x you get the idea.
Hope this helps.

SInce you are a newbie, I can advice you to download wvdial. This is a
pretty good and pretty easy PPP dialler. First you need to install pppd
and chat from your MANDRAKE distribution, and you should enter the DNS
ip numbers from your ISP in /etc/resolv.conf
When you have wvdial compile it (pretty easy) example
cd [wvdial directory]
./configure
make
make install
And then read the man page or redme from wvdial.

I found out that the ipforwarding in the 2.2.x kernels is still very

unstable and sometimes rules don't even work
I suggest you download rinetd it is really easy to configure and install
and it is also very stable. The only disadvantage is, that you always
for ward both udp and tcp packets but he that's where the ipchains

It is slight differnet.
You go ro interNic and claim the gus33.org name.
Then you go to a ISP and ask them to run the DNS for gus33.org. You have
to fill out a simple domain movind form with your name domainname etc.
Then your ISP will run the DNS service for gus33.org and you get f.i.
a hostname www with ip address 195.195.195.195.
What you also could do is, tell your ISP that you wanna claim gus33.org
and that they run the DNS for it. This makes takes less time, since your
ISP has better connections with InterNIC and there are less
communications errors.
If you have a leased Line and you wish to run your own DNS primary, tell
Internic, that the DNS server of gus33.org can be found at the steady IP
address that your ISP gave you. But I don't think you wanna do that
right now.

Look at the chipset on your board and note which one it uses. Then try
looking at the ethernet howto. There is usually a link to an alpha drivers
page. Hopefully you will find your chipset there. I was thinking about
buying that board but I was unable to find any linux drivers, so I opted for

You probably have the smbd set into the inetd configuration.
This will start smbd on demand when a call arrives on the netbios port
138 I believe. Then it will load smbd on demand.
If you wanna get rid of this behaviour the mark the line in the
inetd.conf where smbd is started with a #
Then restart the inetd and start smbd and it will keep running in the

I'm having the same trouble with a setup similar to yours.
If I set the ypclient to 192.168.0.3 (my machines ip address)
NIS works fine but if I set it to 127.0.0.1 I get the
following message from NIS
refused connect from 127.0.0.1
-> ignored (not a valid source host)
-> not served by us
other machines on the network can use the server but if
I try to use ypwhich it says
can't yp_bind: Reason: RPC failure on NIS operation
I've noticed that when running the yp makefile that
it tries to connect to 127.0.0.1 on a different port to
when trying to connect to 192.168.0.3. Any ideas as to why?

Most likely you have made typing mistake or your DNS access is
misconfigured.
In the second case use IP address of the smtp host instead of
its name (and fix DNS).

1) change MX record to show "backup" as secondary mail destination
2) make sure that "backup" is willing to relay email for domains
serviced by primary (It is very important in newer sendmail)
"backup" will try to deliver email to primary at every queue run.
It is up you how often it will happen (e.g. 30m).
So when "primary" is up after long outage, "backup" is able to
send stockpiled email short after that.

Hi,
I've got a strange problem. My internal network is several windows
machines which are connected through my RH Linux 5.1 machine (kernel
2.0.36) to the internet. The gateway is running IP Masquerading and it
seems to work fine for http and most ftp connections. For instance I can
connect as anonymous and download from both ftp.microsoft.com and
ftp.sun.com. But when I try to connect to one of my client's sites
through the gateway the ftp session hangs as soon as I try to download a
file or list a directory. What makes it pretty strange is that if I ftp
from the Linux gateway box to my client's ftp site I can list
directories and download files with no problem.
My client's ftp site is running NT, but I would assume so is microsoft.
What could possibly be wrong. I am assuming that there is some sort of
problem with the masquerading firewall. I've been struggling with this
firewall and port forwarding for almost a week now. This is getting to
be really frustrating.
Any help would be greatly appreciated.
Thanks, Derek
