Security Risk -- Services enabled on Unix Server

Hi,

After a security audit, following security risk items came up. Could somebody pls tell me what are these services for and how can I disable them if they not required?

TIA.

Re: Security Risk -- Services enabled on Unix Server

Well some of them you have what they are. You can safely disable these.

chargen: echos complete character sets back to the connection
echo: echos characters back to the connection

Here's how:
# vi /etc/inetd.conf
Place a '#' at the front of each line.
Save the file, and get the inetd daemon to re-read it's config file.

# inetd -c

Here's a document that might explain a bit more.
