Description charles finlay 2000-12-04 18:56:41 UTC 
xinetd can use /etc/hosts.deny. The following syntax has been acceptable
to the wrappers for years.

in.ftpd:ALL:twist /bin/echo "421 host (%h) does not have access to %s";
/usr/local/etc/tcpd_report %d %u %h


where tcpd_report is just a mail announcement script.

/var/log/messages reports:

Dec  4 13:19:38 bryce xinetd[22167]: error: /etc/hosts.deny, line 21: twist
option in resident process
Dec  4 13:19:38 bryce xinetd[22167]: refused connect from 139.88.189.233

replacing twist with spawn works.

using ftp for test.

Confirmed... it works once, then xinetd exits. Looking into it.
Comment 2 Trond Eivind Glomsrxd 2001-01-21 22:36:41 UTC 
This is fixed in xinetd-2.1.8.9pre14-1, coming soon to a Rawhide near you.
