The following reply was made to PR bin/97499; it has been noted by GNATS. From: Bruce Cran <bruce@cran.org.uk> To: bug-followup@FreeBSD.org, arnoldlee_chn@yahoo.com Cc: Subject: Re: bin/97499: one of sshd_config(5) options does not work Date: Mon, 03 Mar 2008 21:58:10 +0000 The UseDNS option doesn't enable/disable DNS lookups, but enables/disables validation of connections based on host information. As discussed at http://lists.freebsd.org/pipermail/freebsd-stable/2006-November/030886.html there are more reasons a DNS lookup may be done. I'm not sure why the behaviour would have changed between 6.0 and 6.1 though. I've checked that setting UseDNS to "no" on 6.3 results in DNS lookups being done even with the sshd flag "-u0". I'll try 6.0 and see if I can track down what's changed. -- Bruce
