Normally you can enter a Terminal session and use pico with sudo to edit the /etc/inetd.conf to change the line
#ident stream tcp wait root /usr/libexec/tcpd identd -w -t120to
auth stream tcp wait root /usr/libexec/tcpd identd -w -t120However, when you are using an AirPort base station, the process your are responding to won't like the IP address it is getting back. An easy solution is to install Brian Young's nullidentd. Read the rest of the article for the how-to...
I did the following:
- Download the file from the site above and drop it on StuffitExpander
- Open a Terminal window and change directies to the nullidentd-1.0 directory
- Type sudo mkdir /usr/local/sbin (if it doesn't exist).
- sudo make install
- sudo pico /etc/inetd.conf
- Replace:
auth stream tcp wait root /usr/libexec/tcpd identd -w -t120
withauth stream tcp nowait nobody /usr/local/sbin/nullidentd nullidentd
- Reboot or sudo -HUP `cat /var/run/inetd.pid`
- Open up an application that requires identd and it should work with no problem
