Hi linux fellows
I installed Red hat 6.1 linux connecting to a local serve and run well
when I was in utah, now I moved to NY, I got new IP address and domain
name for my computer. How to change my configure file to make it work at
the new address?
If I just boot my machine, it will stop some where after " welcome RED
HAT..". I used "I" to interrupt it, and get to the directory "/", and I
can see all the files.
So which file I need to change to make it work?

Hi!
I would like to use CD-RW (rewritable CDs) as backup media.
I'm using xcdroast to write images of my backup files.
Everything goes as expected, but when I try to write to
any re-writable media, xcdroast gives aborts.
I'm having an IDE cd-writer in my server; does anybody
know what to do? (currently I'm using kernel 2.2.17)

I'm trying to recompile syslog (using RH 6.1) but am unsure where I can get

You could just set it up under xconfigurator with however much memory it will
let you specify (or whatever it probes) and then go in and edit
/etc/X11/XF86Config yourself, changing the VideoRam value to whatever your card
really has (32768 for 32MB).
You can then go back after restarting X and check the logs for verification that
its using the 32MB, if you wish.

From: David Steuber <[EMAIL PROTECTED]>
Date: Tue, 26 Sep 2000 23:34:09 GMT
When I upgraded to SuSE 6.2 a while back, I lost the ability to print
over the network. I would like that back as it is a real pain to
print to a file, copy the file to the computer with the printer on it,
and run lpr from there. I figure the problem has to be with me not
puting in the correct entries in yast on the computer that needs to
print over the network.
I'm hoping that if I provide the /etc/printcaps file from the machine
with the printer, someone can hammer the correct answer into my head.

That depends on the type of connection (modem/DSL or LAN). But the files
are in /etc/sysconfig/network-scripts/.
However it will probably be easier to edit your configuration with
'netcfg'. Also you could use 'linuxconf' for this.

So put it in your startup scripts. If you can't figure out how,
then you've got bigger problems. Keep in mind that the idea is to
obfuscate where it's getting the config information from. Whether
you put it in a script or change the binary, it's only obscured, not
secured. If you want security, it demands a bit of intelligence (in
the form of remembering to start the deamon properly after the next
boot). In most cases, though, the slight change will be enough to
fool the script kiddie in your machine. And I consider it to be
*much* simpler to modify the startup script than to hexedit the
syslogd binary.

This is in the context of setting up a honeypot. Such a system should
be under close supervision, so you'll find out if it reboots. Certainly
on any system performing a vital function it is important that a reboot
should restore it to its proper state, but in a honeypot, it may be more
important to conceal what you've done from the attacker.

The internal LAN NIC.
e.g.
your router will have 2 IPs, 1 is the IP assigned by your ISP.
the second is for your internal network.
supposing you use 192.168.10.1 as the IP for your LAN then the
windows machines should have 192.168.10.1 as their gateway.
better yet, setup your router as a DHCP server (thats what I did) also
and leave windows alone. :)

Turning off Java is a limited option. Reason being I won't even be able

Does "up2date" perform the same function in RedHat? No man pages, and
nothing beyond a terse summary from "up2date --help". Could definitely
use some improved documentation.
