Be extremely concerned about security when connected via a cable modem.
do not run telnetd if you don't need it.
set up a dedicated firewal/GW and or Proxy machine and use ip_masq.
strip the machine down to as few services as posible to start ( it's called
bastion host )
no ftp, http ,telnet, tty , finger , netstat, whois or ping services.
( crond even has a hole )
some important files to pay attention too are /etc/hosts.deny, hosts.allow,
hosts
take complete control over these files and others , such as chmod , su , chgrp,
chown , login ,
passwd , etc.
if you strip the services (and know how to maintain the box manualy ) you can
take control of the /bin , /etc dir's so that no one else can see or execute
them ( the machine will still run just fine ) to do this ( chmod -R
o-rwx,g-rwx /bin /etc ) check your documentation befor you do this for the
correct syntax for your machine & MAKE A BACKUP first on these directories
somewhere else on the hard drive , if you screw it up you'll be locked
completely out of the machine ( hense the security aspect of doing this ) and
you will probably have to rebuild you system.
do some reading befor you go nuts on your machine , But I promise you , you
will be hacked through the cable modem if you don't pay attention to security

Reply-To: [EMAIL PROTECTED]
Date: 21 May 99 04:08:18 GMT
The shop I work in has been using SCO Unix and Compaq server class
hardware for several years. I would like to try and convince my boss
to switch to Linux where we can. (I have been using Debian Linux on
my workstation for the last 2.5 years, and have gotten rather
spoiled. :-)
In all my digging through FAQs, HOWTOs, source code, and web sites, I
have not been able to find any reference to using Compaq server
hardware with Linux. Specifically whether any of the Compaq SCSI
controllers or Ethernet cards (NetFlex) are supported. I am
completely puzzled that there is no mention of them, one way or the
other.
Has anyone had any success running Linux on Compaq ProLiant (2000,
2500, and 4500, I think) or ProSignia (300) hardware? If so, where
can I find info on what drivers to use?
Thanks,
Rob.

I consider buying a emachine's 400i (intel celeron 400MHz) to run linux.
It seems to be a good deal. I plan to add a NIC and some more RAM on it.
I am wondering if its integrated SVGA and sound card works under linux.
Anyone has a successful experience on emachine? Thanks!

Hmmm, VA Linux Systems sells the Intel EEpro 10/100 with their
Quad PIII-Xeon systems - so I think it's okay for an experimental
budget web server. "TRUE" DEC Tulip based cards are almost impossible
to find now. The DEC 2114x and 2104x chips are, to my understanding,
out of production and so many card manufacturers are using the Lite-On
PNIC chipset, a Macronix chipset, or one of several other possible
Tulip clones in their cards. Or they're moving to other cheap
chips like the Realtek or the Via-Rhine.
I'd stick with 3COM 3C905 or an Intel 10/100. I currently like the
Intel.

Subject: Problems using CD-RW with cdwrite
Date: Fri, 21 May 1999 20:25:59 +0200
Hi there,
while trying to write a cd using my Philips cdd 3600 on an tekram DC-390
series
SCSI adapter I' am encountering some serious troubles.
If I try to eject the cd with cdwrite: cdwrite --eject --device
/dev/sga
I get the following errors:
load_unload result 0, pack_id 9 sense F0 00 05 00 00 00 00 28 00 06 F1
37 20 00 00 00

50 53 20 43 44
These same errors are appearing when I try to burm a cd.
I am however able to mount cd's in the CD-Rw as /dev/scd0
I would really enjoy it if I could burn my cd's using linux (yet another
reason
to get rid of Winblows)

Hi,
sorry my last posting was in german.
Does anyone know how to setup a G2 RealServer with broadcast ability? I
already installed the RealServer successfully, but i don't know how to
link the video signal ( i have a bttv compatbile card) with the server.
Please help,
