In some cases certain online protocols like IRC chat or FTP servers may require a proper ident response from the connecting client.

Edit /etc/inetd.conf with your editor of choice and change the relevant section to your actual user name:
#:INFO: Info services
ident stream tcp nowait yourusername /usr/sbin/ident2 ident2 -i -n
