How to change listening port of echo server on RH9? I would like to start it on port 80 (for example).

Edit /etc/xinetd.d/echo-udp
port = 80
restart xinetd

Thanks for reply.

I also have to edit /etc/services file.

I'm doing the same for vsftpd (for portscan reasons) and was wondering: why do you need to change the /etc/services file? and how do you change it (i.e. what do you have to change)
thx.

I can't explain exactly why... but, if I had changed default port of echo service to 80 in /etc/services it started to work. Maybe echo in xinetd is taking port assignment from this file.

Code:

#echo            7/tcp
echo            80/tcp
#echo            7/udp
echo            80/udp

#http           80/tcp
#http           80/udp
