How to make Linux more secure?

there are some nice scripts on this page, i think i mentioned one of them before.
http://rob.pectol.com/myscripts/

atm i use vscan.sh.txt and encryption.sh.txt .if you use Ubuntu and want to use one all you have to do is copy the text to a new document and save it as 'virus scan', 'encrypt' etc, then make it executable and put it in ~/.gnome2/nautilus-scripts you can then right-click files and scan or de/encrypt them

there are threads about the two scripts i have at http://www.ubuntuforums.org/

 

iceni,

Libsafe performs dynamic run-time checks in the C language for the following functions:

strcpy(char *dest, const char *src)
May overflow the dest buffer.
strcat(char *dest, const char *src)
May overflow the dest buffer.
getwd(char *buf)
May overflow the buf buffer.
gets(char *s)
May overflow the s buffer.
[vf]scanf(const char *format, ...)
May overflow its arguments.
realpath(char *path, char resolved_path[])
May overflow the path buffer.
[v]sprintf(char *str, const char *format, ...)
May overflow the str buffer.

It runs tranparently; I tried once awhile back to enable logging to syslog and could not get it to work. The example using "ls" in my previous thread was just to let you see that it was indeed working.

Here is a link:

Libsafe does not protect against ALL buffer overflows.

 

i'll definately try it out in the next day or so (i've just disabled alot of stuff and want to see how that works out first) i can see it's doing it's job. thanks.

 

I have another nasty problem, at least for me it is, where can i find my e-mail folders in evolution mail?, and i don't mean in the program itself but on the HD.
In order to train spamassassin i have to ram some spam down it's throat and in order to do that, from the commandline, i need to know where those folders are located.
I've been looking till i was almost blue in the face, result; nada,ziltch, zero.

Any help in this matter will be greatly appreciated.

hi, i've uninstalled evolution, but your folders should be in your home directory. probably here -
~/.evolution
the . means it's a hidden directory, you should be able to see it if you do this
open terminal
ls -a | grep .evolution
the -a bit shows all folders including hidden directories, if you just do ls -a it will show all the hidden stuff. if you are using Ubuntu you can make hidden directories visable all the time by doing this
Places>Home Folder, then in Nautilus Edit>Preferences, then tick the box to show hidden and backup files.

i hope that's what you ment

 

hi, you might be able to see what's happening with strace e.g.
strace ls

Well, i found the hidden folder but no dice, your suggestion uninstalling evolution might not be so bad, i am going to install thunderbird, at least there i can find the mail folders without any hassle.

Thanks inceni for your assistance.

Edit: I've found it!!, i was about to hang myself when suddenly it was there.
