Standard TCP service; routes everything written to that port to the bit bucket. I'm not aware of any security risks here. > > 13/tcp open daytime > > 37/tcp open time > > ntp daemon, you can safely disable these in inetd.conf No, it's not the ntp daemon; that listens on 123/tcp (see /etc/services). The daytime service responds to connections simply by writing the current time, in human-readable form, to the connection and closing. I think time does the same, but in machine-readable format: [nanny-ogg:~]$ telnet localhost time Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. ÀªH¤Connection closed by foreign host. [nanny-ogg:~]$ telnet localhost daytime Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Thu Jun 6 15:46:32 2002 Connection closed by foreign host. Far as I know, you can safely disable these (I'm not running inetd at all on either of my two machines, and nobody's complained at me yet). As with discard, though, I don't know if they're a security risk. > > 113/tcp open auth > > identd. Keep if you *ever* connect to IRC; most networks will drop you > if it can't get an ident response. Does this service have any uses besides IRC? Richard -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
