Gazette Matters

A couple of small suggestions

Neil Youngman [ny at youngman.org.uk]

First off, TWDT is no longer TWDT. If you click on TWDT you find that the mailbag has "Thread continues here" links. Could we make TWDT be TWDT?

Secondly, we have the answers to last month's geekword. It would be nice to have the questions with it, so anyone that wants to admire the subtlety of the clues, or pick nits, don't have to flick between windows.

Schema for nmap XML Output

Amit Kumar Saha [amitsaha.in at gmail.com]
Tue, 20 Feb 2007 09:31:10 -0800

hi list Attached is the XML output for a Nmap scan

[[[ I have actually included it below. - Kat ]]]

The goal is to move Nmap XML files into a database, with a well-thought out DB schema. Ideally, this should work with PostgreSQL, MySQL, and other popular databases.

Please suggest a possible database schema for the same

Please point out any similar works

Well, there's all kinds of stuff you could do with 'apt-cache' to tell you where the files are, but in short, they're all under '/usr/share/doc/lg*'. In fact, '/usr/share/doc' should be the first place you look for anything on your system that doesn't have built-in help or a manpage.

For future reference, the editor@ address at LG is used for article submissions and publication-related issues. If you have more general questions like the one above, please send them to The Answer Gang (tag at lists.linuxgazette.net) - that way, the answers get shared with the rest of our readers and benefit the entire community. I've CCd TAG on this exchange.

Purpose of some spam messages?

Kapil Hari Paranjape [kapil at imsc.res.in]
Thu, 1 Feb 2007 17:58:37 -0800


I was just wondering if someone has thought about what is the purpose of SPAM messages which only contain some mish-mash text. The qualifying criteria are:

	1. Only text without attachments.
	2. Text that contains incoherent sentences or disconnected sentences. [*]
	3. Definitely messages from addresses not known to the recipient.
(The last is to exclude e-mail messages written by friends who are not quite sober at the time of writing :-)).

Here are some possiblities that occured to me.

A. These are messages that are designed to test/mar the efficiency of the spam detection systems currently employed by servers.

B. These messages contain coded messages that are flooded across the internet in an attempt to disguise their true origin/destination. The real message could be short one such as "the machine from which this has been sent has serious security holes".

C. This is generated for someone's research project.

D. This is the result of some spam generating software/virus which has bugs.

I don't know if this is worth wondering about ... except ... why is someone going to some trouble to make (a program which is making) life difficult for everyone?

Pointers to prior discussion welcome.

Thanks and regards,

Kapil. [*] Clearly (2) is subjective which makes such spam hard to detect automatically. --

how did it(the webzine) all start?

MNZ [mnzaki at gmail.com]
Wed, 21 Feb 2007 23:49:52 +0400

Dear TAG, I am a regular reader and wanted to first thank you for the great zine. I'll probably be starting my own site/zine (long story short: 'tis all to keep in touch with my friends, who I have known for all my life but will have to leave them soon). The zine part won't be linux related(except maybe for one column every now and then).

I know I talk too much but, my question(s): When LG first started out, how did you get the readers? How was it publicized? How did you get your very first reader? Also any tips (Kat? Ben? team?) ?

One more thing: Write more POLOTMs or else I'll have to resort to violent methods!

Love that URL in part 2. Freakin' "0xc8.0x2b.0x50.0x74"? You'd think that anyone dumb enough to just click on URLs in these "bank" emails has already been stripped to the bone by sharks, but a) it doesn't kill them off, and 2) There's One Born Every Minute. I guess the spammers and the scammers will never run out of "soft targets".

Just for fun:

Ah, a default install of RHEL that got cracked. I'm feeling a bit too lazy to ping the admin myself... it would be like sweeping back the tide.

Followup: please recommend books about Linux

JOHN INGRESS [ingress at sbcglobal.net]

[[[ This is a followup to http://linuxgazette.net/134/misc/lg/please_recommend_books_about_linux.html - Kat ]]]

Thanks. I have to admit I have not yet taken your advice, though they sound like good suggestions. I did, however, find Marcel Gagne's book Moving to Linux at the library. He mentioned Mandrake. I went to their site, now Mandriva, and downloaded Mandriva One, a free release (I'm willing to pay, but my needs are light...no gaming, just music, video, word processing.) However, when I try to open it, Microsoft says it can't find the file to open it, and I get lost after that. I've had MS Windows for 5 years, which I installed, and I have downloaded a dozen or two programs, but I'm still a newbie, I need specific instructions in some cases. Like this one. Any help would be most appreciated. The "Blue screen of Death" is killing me! Thanks. John

My wireless - unsupported - card is inprocomm 2020 in an Acer Aspire Laptop.

I managed to get it working (with ndiswrapper - wifi radar and so in) in UBUNTU 5.04 en 5.10 but not in UBUNTU 6.04 and 6.10.

It simply is not recognised.

Cab you help, please?

Mandriva 2007 - WiFi cards cannot find network

Savill, Owen [Owen.Savill at analog.com]
Mon, 5 Feb 2007 13:03:31 -0000

Hello Answer Gang,

This is my first time posting to you so I hope I get it right.

I am having big issues with my WiFi connectivity. Basically everything seems to be okay but attempting to ping an address results in a network unreachable message. I've used drakconnect to setup the wireless setup. The router itself is reporting the card as attached ! And ifconfig shows a continuous stream of traffic to the card but nothing from it.

The contents of /var/messages looks fine, apart from perhaps the last line:
