when dnsmasq is started, it does not provide ip addresses, but it was configured properly - i think (config is attached). dnsmasq is listening to requests, sheissi ~ # netstat --program --numeric --all --inet | grep dnsmasq tcp 0 0 192.168.0.1:53 0.0.0.0:* LISTEN 8853/dnsmasq tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 8853/dnsmasq udp 0 0 0.0.0.0:32771 0.0.0.0:* 8853/dnsmasq udp 0 0 192.168.0.1:53 0.0.0.0:* 8853/dnsmasq udp 0 0 127.0.0.1:53 0.0.0.0:* 8853/dnsmasq udp 0 0 0.0.0.0:67 0.0.0.0:* 8853/dnsmasq but both dhclient and dhcpcd get a timeout when trying to get an ip address. in the daemon.log there is no sign that a dhcp-client tries to get an address (but dhcpd does provide addresses, so the clients just work fine).

Do you have a firewall on the box? You need to allow DHCP packets through your firewall.
you're right! in fact my firewall was blocking the DHCPDISCOVER packets. i didn't realize that because dhcpd just worked fine! does dhcpd modify the iptables?
dhcpd bypasses the firewall, while dnsmasq does not
