My home dial-up machine gets scanned pretty much every evening for samba shares. I intend to develop a small samba share of poisoned files padded out with 0s (so they compress well and go up the modem fast). Yes, don't let anything listen to the external interface unless absolutely necessary. netstat -a will show what's listening. inetd always seems to want to listen to everything, but you can use "ALL: ALL EXCEPT 127." in hosts.deny (man hosts_access) to pin that down to only the local machine (change to taste) for most services it starts. Commenting out some lines in /etc/X11/*/Xaccess is also good, as in running X with -nolisten tcp if you don't use that. And use ipchains/iptables just to be sure. -- MJR

Sadly it seems to mean the nux admins are losing permanent jobs again, though. Maybe that's just what I'm seeing, or maybe we're about to have a resurgence where they *stop* employing busloads of NT/2k admins to patch that service together and employ nux admins to roll out a stable service. > 4)Lack of availble software, on this one they are right, there is > limited stuff for an epos system to use.

This is useful: http://www.linuxgazette.com/issue65/lg_toc65.html "A Private Home Network" By Jan Stumpel Here, Jan goes though the steps needed to isolate a linbox from the outside world & still be able to use internet. Some other good articles in that issue too. Steve >on Fri, Jun 22, 2001 at 09:18:51AM +0100, Vanisa Surapipith scribbled: >> >> Can virus attact a linux system?

Insurance Co. charges more if a company uses NT than Open Source
by George Waring 22 Jun '01

22 Jun '01

See: http://www.zdnet.com/intweek/stories/news/0,4164,2766275,00.html Offered in counter-point to the M$ claim that was made in "That Word Document." The greater security that M$ claims with their OS is not making much of an impression in the insurance industry. Insurance against the damages caused by hacking bears a 5 to 15% higher premium for Windows NT. George.

Virus on Linux?
by Vanisa Surapipith 22 Jun '01

22 Jun '01

Hello, I just join ALUG and have a newly installed Red Hat 7.1 on my PC. I hope to explore it fully but there comes a concern on virus. Can virus attact a linux system? People with MSWindows are constantly affected and need to update their Norton or McAfee virus scanner. Is there a similar thing in linux world? Cheers, Vanisa. &------------------------------------------------------------------------& Ms Vanisa Surapipith (Research Postgraduate) School of Environmental Sciences University of East Anglia, Norwich, Norfolk /_____T NR4 7TJ, United Kingdom.

Is there > a similar thing in linux world? Viruses could exist on Linux, but they would have trouble infecting other users on the same system, assuming most of your programs are installed as root and you log in as another user. That's why people say you should be very cautious about doing anything other than the bare minimum as root. Worms and intrusions are more common. That's why everyone says to keep up to date with patches and security updates. As your machine was professionally installed, I assume they installed all known security updates? With RedHat, I don't know if there's an automated tool with it, but you can keep safe by reading either the "Security" page of LWN, http://lwn.net/ (out every Thursday), or the regular Security newsletter (out most Saturdays) from http://www.linuxsecurity.com/ -- MJR

Is it a 509? have you tried either using the debian 3c5x9utils or the 3c5x9config dos batch file where you can change the card settings? Or more simply, isn't there a config file hanging round somewhere where you specify whether the card will use 10Mbps or 100 or whatever? Jenny

RE: Microsoft FUD

Hi all, Had to download that article .... fantastic! (Literally.... pure fantasy). Just a comment, the output from running strings on it is actually visible via the document properties if you have MS WORD -file->properties->custom (I'm writing this at work.) Just for clarity , the line "our latest anti-linux paper" is actually the _EmailSubject property. Huh? Well, that means it was the working title used whenever the document was emailed internally. Thus (presumably) it wasn't meant to remain with the article, ... M$ are quite adept at this 'small oversite' completely destroying their arguments thing, ie. No need to read the article, you can see where its coming from. But it will be intersting to check back in a week or so and see if this line has been removed.... cheers Earl
