In freebsd 6.0, I use the option "UseDNS no" in the /etc/ssh/sshd_config, it works ----- when I use secureCRT to login, sshd doesnot look up dns, mpd doesn't auto dial. In another computer, I installed fb 6.1-stable with the same sshd_config. But the option "UseDNS no" has no effect! Whenever I login use securecrt, mpd will automatically dial out to internet to access the dns! What is more, the sshd versions in fb 6.0 and fb 6.1 are the same! So I think maybe there are something wrong with the operating system. >How-To-Repeat: edit /etc/ssh/sshd_config, change "#UseDNS yes" to "UseDNS no", and set /etc/resolv.conf properly("nameserver Your.DNS.IP.Addr"). Now login using ssh2 protocol via sshd, you can capture packets sshd sends to dns server(s). >Fix: >Release-Note: >Audit-Trail: >Unformatted:
