Re: Newbie - wants to close ports



Hi
Disable services. Edited /etc/inetd.conf and add # to unwanted service or
use update-inetd program to complete task. Restart inetd super daemon
/etc/init.d/inetd restart

stop service ex /etc/init.d/named stop
/etc/init.d/program_name add beginning of script 'exit 0'  examble of named
(listen 53)

Anyway if you not need service REMOVE IT examble
apt-get remove program_name These is suitable for most services under init.d

Use man/info service_name You will found most of cases more information...
/usr/share/doc/package_name You will found  package documentation...

/usr/share/doc/HOWTO/en-txt should be installed your system (Debian3.0) read
firewall and security HOWTOs and check Debians own document
http://www.debian.org/doc/manuals/securing-debian-howto/index.en.html

Remember You need some services for system... so I recommed You read the
first.
