Not a serious virus, but it shows that viruses can be written for Linux and can infect Linux systems.

I think even the preteens who run Linux because they heard it allows them to hax0r like an 31337 movie character are bright enough not to run in root and open dodgy email attachments.

Oh well, people are idiots - just look at the sales of Windows.

yer right, i don't think anybody uses root for anything besides modifying user access properties or configuring stuff in the files that you can't access as normal user.

I've logged in as root on my present Linux system exactly once.  I use the su root command to gain command line root permisions to edit config files, and Mandrake asks for root password when you try to do most things you need root for.

i use 'su' when i can but i don't know all the commands. i only started with Linux about 5 days ago lol. i only know 'chown' then the user name......when i had a problem getting my webpage to show, i asked my buddy at maverick.mahan.net and he said a command called 'chmod 755 index.html' and now i can see it....thing that sucks is that i don't know where that 755 comes from or the 777 he said as a backup..

Those numbers set the file permissions. There are three permissions: read, write, and execute. There are also three levels: user, group, and world.

Code: [Select]

To form the complete permissions number, just add the above together. Thus, read, write, and execute for the user, read and execute for the group, and execute for the world would be: 400 + 200 + 100 + 40 + 10 + 1= 751. Actually, what you're doing here is a bit-wise OR. Addition comes out to be the same so long as the sums don't carry over.
