wu-ftpd now _always_ does a RFC931 ident lookup on the incoming connection - there is no option to disable it. For users behind firewalls that drop the ident connection attempt, this means they take 10 seconds just to connect (before even giving a username). This needs to default to off and be a configurable option.
dkl - can you check the wu-ftpd-2.5.0-3.src.rpm in my SRPMS directory on devserv.devel.redhat.com. That has a new "-I0" option to turn off ident checking, as well as man page update Alan
Fixed (by building for 6.1) in wu-ftpd-2.5.0-3.
