====== DHCP Server via DNSMasq ====== To set up a DHCP server you can use the dhcp package (included with Slackware) \\ **or** \\ you can do it the easier way and use DNSMasq (also included with Slackware). **Assuming that you do not have DNSMasq installed:** - Install the official dnsmasq Slackware package either by [[slackware:pkgtool|pkgtool]] or [[slackware:slackpkg|slackpkg]]. - Make DNSMasq start on boot:


# chmod  755 /etc/rc.d/rc.dnsmasq

(At this point you will have a really cool little DNS on your box but, that's not what we're going after here...)\\ **If you already had DNSMasq running on your box, start here:** - Edit the /etc/dnsmasq.conf file:


CHANGE:
    #dhcp-range=192.168.0.50,192.168.0.150,255.255.255.0,12h
TO:
    dhcp-range=1ST_POOL_IP,LAST_POOL_IP,12h  (using your correct IP range)

- If your DNSMasq box isn't also your gateway router, tell your DHCP clients who is the default gateway:


CHANGE:
    #dhcp-option=3,1.2.3.4
TO:
    dhcp-option=3,YOUR_GATEWAY_IP

- Start/restart DNSMasq:


# /etc/rc.d/rc.dnsmasq restart

You should now have a working DHCP server. ===== Persistent IP addresses ===== To assign IP addresses based on a device's MAC address, edit the file ''/etc/dnsmasq.conf'' and add the following line for every device (using the correct MAC and IP address of course):


#EXAMPLE:
dhcp-host=11:22:33:44:55:66,192.168.1.61

NOTE: The IP address should be **outside** the DHCP address pool. ====== Sources ====== * Originally written by [[wiki:user:arfon | arfon]] {{tag>howtos software dhcp dhcpd dnsmasq author_arfon}}
