I have a Windows server that runs both the DNS server and DHCP server for my network. When I added a Slackware box, I needed the Windows server to update DNS when the slack box obtained a DHCP lease. Windows was already setup to do this, but the default slack install didn't send the correct information for the Windows DHCP server to setup the DNS A record. Here is what I did to get slack to work:<br />
<br />
First, slack uses ''dhcpcd'' for a dhcp client. Looking through the options and testing revealed that all I needed to do was send a:<br />
<br />
<pre>-h [hostname]</pre><br />
<br />
with the dhcpcd command. In order to get slack to do this, I had to edit:<br />
<br />
<pre>/etc/rc.d/rc.inet1.conf</pre><br />
<br />
and set:<br />
<br />
<pre>DHCP_HOSTNAME[0]=[hostname]</pre><br />
<br />
then:<br />
<br />
<pre>/etc/rc.d/rc.inet1 restart</pre><br />
<br />
and everything worked!</div>Erik
