This means you seem to access /home/gary/kvirc_home, but in fact you will access /home/gary/.kde/share/apps/kvirc. To see where a symbolic link points to, do an "ls -l ".

I am not all that up to speed with the security levels, but I do know that these levels determine how far you can go with things. Low security lets you do anything with the system, and others too, which makes it not very stable as a crucial server etc. For that you install high security. This makes a lot of things impossible, thus warranting that the machine will be as safe as anywhere possible. E.g., you can't shut down the system remotely that way, incidentally downing a webserver or so. Hope this helps! Paul -- If you lose money, you lose nothing. If you lose (the) honour, you lose a lot.

Just a way at quick glance to organize your files. Imagine you just downloaded a few 'rpm' packages, you open a terminal window and do 'ls' to see what you've got; if they're all the same, it would be a little more of a strain to find the files you're looking for. I don't think there's any tricky formula behind it; in my directory, text files are green, executable files are bright green, rpm's and tar.gz files (both are archives - just different types) are red, and graphics files are purple. The '@' symbol designates a symlink (shortcut) and the '*' is another way to indicate an executable. 2. I don't really know the 'exact' differences between the security levels; maybe experiment? You've basically answered that one already though. I would generally say though, that not all distros use the same terms for the same environment; i.e.; what would seem to be 'medium' security in Mandrake may very well be 'high' security in SuSE. I believe that's just a matter of personal preference, and you've already seen the results. I've loaded both SuSE and Mandrake / Red Hat distros and have seen that when trying to use the minicom program (similar to hyperterm in windows), I have to change permissions on the Mandrake / Red Hat version but on the SuSE version, the $user is able to use it right out of the box.

What do all these, besides the ones I > have mentioned mean? It is due to the fact that mandrake sets up several aliases during install. type "alias" and you will see that ls stands for "ls --color=auto -F" (--color=auto for colors and -F to add @ to symlinks, * to executable files, / to directories, ...) man ls for more details > > 2.

This is handled by the msec package. Look at /usr/doc/msec/security.txt and msec.ps for details about different security levels. You can use the msec command to switch from one security level to another (man msec) > TIA, > Gary Morgan HTH Flupke -- << There's no place like ~ ! >>
[newbie] simple question
ok, I'm new to Linux, the only knowledge I have is from the books I have read. But all of them have seem to skip over, what seems to me as, simple questions. 1. I notice when I do an "# ls" I get a directory listing but some objects (files, directorys etc.) are listed in different color text, or have distinctive markings next to them (ie. directories are blue, symbolic links have the "@" symbol next to them). What do all these, besides the ones I have mentioned mean? 2. What are the exact differences between the install security levels? I noticed that if I install with "High" security I cannot, by default, login via ftp or telnet, even from the local machine, and I cannot restart (via ctrl-alt-del) without being logged in first, however I can do both if I install with "Medium" security.

Javier, Como en englias? por favor? I understand what you said ;) ps -a shows all services, yes, I am looking for running deamons though. And alot of services I know are running do not show up under ps -a.

Re: [newbie] simple question I think?
Have another problem, if I try and "surf" from the IP Masq, netscape for whatever reason locks up. It did not do this yesterday and nothing has changed as far as I know on the Linux box? Any Ideas?
