I made all the changes necessary as you could see in my previous message.

I'll try that but it should work with multiple hosts, too.

Nope, access is granted when hosts.deny contains "all: all: deny" AND
hosts.allow contains "all: 127.0.0.1: allow". That's the way it works with
other daemons. I tried also with and empty hosts.deny file, no success.

Booting was unnecessary. hosts.{allow, deny} are read every time tcpd is
executed ie. when a daemon is started by inetd. So the changes take place
right away.
Anyway, back to my problem.
Has anyone succesfully configured selective relay with tcp_wrappers ??
Or do I have to install tcpserver ??
