how to close open ports
hi friends!
i read somewhere that i can close my open ports by putting a '#' before the lines containing that port no. in the file inetd.conf but since the latest varsions have started coming with the more secure xinetd.conf how can i customize it? thanx in advance. |
aint it in the manual? I aint running xinetd, but ports are bound to a running service, so if im caught guessing its either adding it to the
"disabled = (servicenames)" in the main part of the xinetd.conf or comment out the whole per-service part like "# service (servicename) { # args # args # args # }" btw upgrade to the latest version of xinetd, it has had some bugs. |
Hi,
I agree first patch the xinetd for security fixes. The easiest and quickest way to do this is to create a directory in the /etc/xinetd.d directory called disabled. Then you should see the start up services scripts in /etc/xinetd.d like this -rw-r--r-- 1 root root 297 Feb 27 17:17 chargen -rw-r--r-- 1 root root 321 Feb 27 17:17 chargen-udp -rw-r--r-- 1 root root 297 Feb 27 17:17 daytime -rw-r--r-- 1 root root 321 Feb 27 17:17 daytime-udp -rw-r--r-- 1 root root 289 Feb 27 17:17 echo -rw-r--r-- 1 root root 312 Feb 27 17:17 echo-udp -rw-r--r-- 1 root root 318 Feb 27 17:17 finger -rw-r--r-- 1 root root 259 Feb 27 17:13 ntalk -rw-r--r-- 1 root root 361 Feb 5 22:43 rexec -rw-r--r-- 1 root root 378 Feb 5 22:43 rlogin -rw-r--r-- 1 root root 431 Feb 5 22:43 rsh -rw-r--r-- 1 root root 317 Sep 30 2000 rsync -rw-r--r-- 1 root root 247 Feb 27 17:13 talk -rw-r--r-- 1 root root 305 Jan 22 13:52 telnet -rw-r--r-- 1 root root 321 Feb 27 17:17 time -rw-r--r-- 1 root root 317 Feb 27 17:17 time-udp Move each file service name to the new disabled directory "/etc/xinetd.d/disabled" that you don't want started. Then type: /etc/rc.d/init.d/xinetd stop /etc/rc.d/init.d/xinetd start To enable a service again simply move the file back and stop/start xinetd. Raz |
Didn't even think of the new disabled directory idea, been commenting eveything out of each folder sepratly...
