DHCPD is slow

barn63 · 04-29-2006, 01:54 AM

I configured my DHCP server using DHCPD and it assings IPs and all the good stuff right but it takes 10 times longer then my windows dhcp server did. Has anyone else had this problem and is there anyway you can speed up how fast it assigns ip addresses?

try using dnsmasq instead. It combines dns/dhcp server functions in one easy to use dameon and it is meant for speed with a small network (around 100 or less clients). To use it, install the dnsmasq slackware package, then make /etc/rc.d/rc.dnsmasq exacutable. The conf file is /etc/dnsmasq.conf. It is very well commented with many examples. Just set up your rules as you see fit.

Thanks for the suggestion. I will give it a try.

Does anyone have and example dnsmasq.conf that I can look at that is configured for dns and dhcp.

it works out of the box, all I changed on mine was:

Code:

...

# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
interface=eth1
# Or you can specify which interface _not_ to listen on
#except-interface=

...

# Uncomment this to enable the integrated DHCP server, you need
# to supply the range of addresses available for lease and optionally
# a lease time. If you have more than one network, you will need to
# repeat this for each network on which you want to supply DHCP
# service.
dhcp-range=192.168.0.102,192.168.0.199,12h

...

All of the other default settings worked fine for me. You only need to change things if you want extra configuration on your network.

So basically you just tell it to use the correct interface and tell it the range and lease time? What about the DNS stuff?

Awesome. That worked PERFECT. Thanks a millions....I woule be lost without this forum.

Read the comments in the dnsmasq.conf, it tells you everything it does by default and what to do to change the default.
