It appears to me that the author has explained why the result is showing 0.000 seconds: 'run' never gets called, as it says in his article. Was there something you wanted to add?

In the future, please use the Talkback: link at the bottom of each article to comment on it; that sends the mail to the correct address and allows The Answer Gang to discuss it. I've forwarded your e-mail to TAG for you, this time.

Thanks,

Hello,

I hadn't read more than a couple of lines into this article and I already knew that I would like it. Reading further only confirmed my initial reaction.

Great article!

Here's a twist from Oliver --- "Please, Sir! Can I have some more?"

Regards,

Kapil. --

Greetings from Germany.

I read the Book "IPCOP" from Packet as well. I work as network engineer / firewall engineer with Checkpoint Firewalls, Cisco PIX Firewalls, Symantec / Axxent Raptor Firewalls and even with IPCOP and Linux iptables firewalls. I never saw a pice of shit like this. This book is perhaps even illegal, it seems to be a copy of the IPCOP firewall handbook itself.

DONT READ THIS.

Hi, Ireaded your article about 6 seat Linux enviroment.

I have an idea from that, but I don't have anyclue how to do it. I Have Ubuntu 6.10, gnome, and 2 disjointed screens. Now I'd like to bind 2 keyboards, one for each screen, but still use my mouse as of now, jumping to another screen over the edge of monitor. Would that be possible in any way?

Hi folks,

A quick question about this month's Geekword --- clues 23A, 15D and 18D all seem to refer to clues that don't exist. Is this a mistake or have I misundersttod something?

I have read your article discussing swf and possible open-source readers and players. My Debian Linux machine (a Mac Quadra running Sarge) is nowhere near adequate to your suggestions. Is there a swf to jpeg converter that could run on my system?

Thanks - Larry in the Ontario deep woods.

Hello, I have a warning to add to an old article on your web it can be found at http://linuxgazette.net/120/smith.html

not every Intel 537 modem will work with this. if you could tell the users to stay away from the intel 82537EP chipset, at the moment they are incompatible with the wcfxo module.

Thank you for your time,

There are also a fair number of problems with NX.

- It is based on a rather old verson of the X server. That X server has several known security bugs. There is a reason most distributions do not ship even the open-source NX parts. - Resuming a session doesn't always work. Murphy says it fails to work when it's most likely that your session has important but unsaved data in it. :-/ - The song+dance with the separate "nx" user and the client ssh key is completely unnecessary. Using a straight ssh login would be a whole lot simpler. It would also be more secure, because the user would be able to use their ssh keychains instead of typing in a password. - Relies on a patched ssh client. An old ssh client. A patch which introduces a lot of code that belongs in a separate program.

The fact that the security people of several major distribution have basically vetoed including NX should tell you something.

Hi there, Just want to say thank you for putting this up again. LG #134 dropped this section and I was so disappointed because I look forward to it every month. It is fun playing with terms and find out lots of holes in my knowledge. Thank you again.
