Stupid question from John Seago
by John Seago 25 Jun '01

25 Jun '01

I have made a start on 'Running Linux', and have got to the passage which entreats beginners NOT to ask simple questions. The problem is whilst I can work the word processor etc., in windows, I don't know how to do much else, so I'm ignoring the sound advice and asking stupid questions, I have no doubt that there will be others. Having, by a combination of a faulty CD, a CD drive which didn't like the first disk of Mandrake 8 had to reinstall Mandrake 8 I have in the long list of script which scrolls down at the beginning 1 item marked [FAILED] in red. The item refers to the Kernel libraries, my question is: Is this Failed notice appearing because I didn't use the second disk, if so how do I put the contents of the second disk in please?

(www.sharesniffer.com) It's looking for Windoze (but will of course find any SMB public shares) I have a load of virus algorithms in zip form I could let you have if you wish to set up a SMB 'honeypot' - sorry about the misappropriation. I was actually thinking of doing something like this, put a load of XL/Word files on a drive which are actually just these things. Some are disk crunchers, others boot sector infectors (TSR as well), others just lock your cpu into infinite loops etc. The 'nice' approach would be to just call them MyVeryImportantCreditCardsDetails.doc or something, and the lame script kiddie who has just scanned your machine for things will download it and probably try to open it in Word straight away, excited at the perceived goodies. ..... one would hope that such a donkey is not running a good virus checker. Many are in Assembler for easy inclusion into any proggie..... Been looking for an excuse to use them (only have them for research purposes .... honest..!)

This is still a plan if it is still required. Sorry I've forgotten but I know there are a few others who are into this sort of thing (to the point of test-hacking their own machines, playing with nmap/nessus and others. It would be a good idea to collaborate for this, and do a proper job of it as a team... Mail me off list guys and let's start planning, we could have a nice little demo together for the next meet.

I thought I had been hacked, turns out the uptime couter >wraps ;).. I remember that one, and saved the mail for future reference! In fact, it'll have to come down soon, to be replaced with a P200 running 2.4.x and iptables. Shame, cos it'd be nice to see it hit a year. In fact, the last power down was the result of a server-room refit, and I've forgotten how long it was up before that. It has never fallen over, and for sure has run for more than a year with no problem of its own making. Let's just say it's been reliable! Here's the ifconfig on the internet-facing NIC (3C-509): laurie@firewall:/home/laurie > ifconfig -i eth0 eth0 Link encap:Ethernet HWaddr 00:C0:F0:4D:2F:E4 inet addr:213.155.158.242 Bcast:213.155.158.243 Mask:255.255.255.252 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:28597916 errors:2 dropped:0 overruns:0 frame:2 TX packets:28085146 errors:0 dropped:0 overruns:0 carrier:0 collisions:35357 txqueuelen:100 Interrupt:10 Base address:0x6000 It's fairly active for an old girl!

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.
