Ident is harmless, but I heard unsubstantiated rumors that ident has a
remote root exploit in it. One thing that I DID confirm was that ident is
not run through tcpd in many default configurations, so you should change
the ident line in /etc/inetd.conf to use tcpd like the rest of the
services, just to be safe. (Then the worst that could happen would be a
remote access hole, which is pretty harmless most cases).
