This is yet again only an attempt to bypass the problem, not fix the cause.
As it turns out, it looks like this would not work anyway, at least for "who". It looks like the delay is not caused by the DNS lookups for the "ALL:PARANIOD" validation by tcpd, but by who attempting to do a DNS lookup of an invalid hostname. However, in the case of the problems with telnet, it looks like something different is going on. The fact that adding the host to your /etc/hosts file seemed to fix it tends to suggest that there is some other problem with your bind configuration.
