hi, im having a problem with nessus ,, I get the installer nessus-installer.sh , so I try ...
sh nessus.sh and it returns "The script needs uudecode(1) to run properly ,after that i try this on my console sh --help and the return was
----------------------------------------------------------
sh [GNU long option] [option] ...
sh [GNU long option] [option] script-file ...
GNU long options:
--debug
--dump-po-strings
--dump-strings
--help
--init-file
--login
--noediting
--noprofile
--norc
--posix
--rcfile
--restricted
--verbose
--version
--wordexp
Shell options:
-irsD or -c command or -O shopt_option (invocation only)
-abefhkmnptuvxBCHP or -o option

-------------------------------------------------------------

So what uudecode(1) ..means?
Any Ideas? Thanks... and im a newbie so be easy with me LOL..

Either you need to be root to install OR uudecode is not installed.

# locate uudecode
/usr/share/man/man1/uudecode.1.gz
/usr/share/emacs/21.2/lisp/gnus/uudecode.elc
/usr/bin/uudecode
/usr/arch/linux.i386/bin/uudecode

# rpm -qf /usr/bin/uudecode
sharutils-4.2c-436

So uudecode is included in the sharutils package, BUT first try

su -
<root password>

and then try installing nessus.
