    <description> &lt;p&gt;Have you found a solution?&lt;/p&gt;
&lt;p&gt;What do you get on the host machine when you &#039;nslookup &#039;?&lt;/p&gt;
&lt;p&gt;Cheers,&lt;br /&gt;

    <title>Yes, I set up a DNS server</title>

    <description> &lt;p&gt;Yes, I set up a DNS server last year and it really did my mind in. &lt;img src=&quot;https://www.webmaster-forums.net/misc/smileys/wink.png&quot; title=&quot;Wink&quot; alt=&quot;Wink&quot; class=&quot;smiley-content&quot; /&gt;&lt;/p&gt;
&lt;p&gt;I suppose I should have thought to that.&lt;/p&gt;
&lt;p&gt;I guess that will probably solve the problem. I really don&#039;t want to got the static IP route and the UseDNS no actually made the problem worse. Not sure why.&lt;/p&gt;

    <description> &lt;p&gt;Interesting. I took it to mean that the problem is with the client having trouble finding the IP address of the Web server from the DNS server.&lt;/p&gt;
&lt;p&gt;Unless you don&#039;t have a DNS server? To lookup host names with any speed you&#039;re going to need a DNS server connected to your DHCP server. This &lt;a href=&quot;http://www.debianadmin.com/howto-setup-dhcp-server-and-dynamic-dns-with-bind-in-debian.html&quot;&gt;DNS/DHCP tutorial&lt;/a&gt; looks quite promising, if you&#039;re using Ubuntu, some other distro, FreeBSD or whatever, do a Google search for &#039;dns dynamic update dhcp &#039;.&lt;/p&gt;

    <description> &lt;p&gt;Yes, it is likely sshd is attempting a &#039;reverse DNS lookup&#039; on your IP address, and that lookup is timing out because there usually is no answer...&lt;/p&gt;
&lt;p&gt;You could:&lt;br /&gt;
1) Set up an internal DNS server that reverse maps all your internal IP addresses to a &#039;name&#039;&lt;/p&gt;
&lt;p&gt;2) Set UseDNS = no in /etc/ssh/sshd_config&lt;br /&gt;
-- You may need the latest and greatest OpenSSH / sshd for this to work...&lt;br /&gt;
-- This is an all or nothing config that you may not want to apply to all incoming connections...&lt;/p&gt;
&lt;p&gt;3) Not a fix, but a workaround: Assign your XP machine a static IP address, either through configuration your DHCP server to always hand it the same IP address, or TCP config on the machine itself... that way your /etc/hosts entry fix lasts a little longer...&lt;/p&gt;
&lt;p&gt;Cheers,&lt;br /&gt;
Shaggy.&lt;/p&gt;
