Re: [Dnsmasq-discuss] DHCP Logging
Hi Tony, I think dhcp-script can be used to log any information related to dhcp assignments in custom format. I think basic dhcp request informations is logged even without log-dhcp. Have you checked syslog or journalctl? Example from libvirt instance: DHCPOFFER(virbr0) 192.168.122.161 52:54:00:4b:aa:67 Is that enough? Is something important missing?

[Dnsmasq-discuss] DHCP Logging
Hi folks, I am hoping I have missed the option to log all dhcp assignments. The only one I have found id --log-dhcp which seems to log a lot more than time,date,ipaddress, mac address and lease time etc. -- best wishes Tony White ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
Re: [Dnsmasq-discuss] dhcp logging and dhcp-range static configuration
Hallo, Simon, Du meintest am 03.09.12: Is there a way to prevent logging the DHCPDISCOVER request for unconfigured hardware address in dhcp-range static mode ? Try dhcp-ignore=!known or possibly the old syntax dhcp-ignore=#known Additional question: When I have 2 NICs, and one of them uses dhcp-host=..., how can I tell dnsmasq that all unlisted clients (which have no dhcp-host-line) must use the other NIC?

You'll have two dhcp-range lines, one for the addresses in each subnet. Have one dhcp-range match the known tag, and one match the !known tag. Viele Gruesse!

[Dnsmasq-discuss] dhcp logging and dhcp-range static configuration
Hello everybody, I'm running the provided centos dnsmasq version 2.48, and I've got a question regarding logging of dhcp requests. I've configured a static dhcp-range to assign ip addresses to well know system using their hardware address. Something like the following : dhcp-range=192.168.0.1,static,255.255.255.0 dhcp-host=net:x86_64,00:30:99:99:99:1C,node1,192.168.0.2 ... The problem I've got is that my log file are full of unhonored dhcp requests (which is normal, since they don't have any dhcp-host entry in dnsmasq.conf) : DHCPDISCOVER(eth0) 00:30:98:87:65:f0 no address available ... ... Is there a way to prevent logging the DHCPDISCOVER request for unconfigured hardware address in dhcp-range static mode ?
