Description Tim Waugh 2000-10-09 16:37:05 UTC 
/etc/xinetd.d/swat currently has:

	only_from = localhost

This causes xinetd to do a reverse name lookup for each connection on that
service to see if it's canonical name is 'localhost'.  For better security
it should read:

	only_from = 127.0.0.1

Comment 2 Tim Waugh 2000-10-16 17:09:10 UTC 
No, this is something different: it's a security problem (DNS spoofing) rather
than a confused application.
Comment 3 Bill Nottingham 2000-10-16 17:25:20 UTC 
It's the same fix, however. :)
Comment 4 Bill Nottingham 2000-10-16 17:33:25 UTC 
... and it's fixed in -22.
