[Dnsmasq-discuss] serving EFI and traditional BIOS at the same time

2014-02-18 Thread Olaf Hering
In my network a Fritzbox is serving DHCP to clients, and my workstation runs dnsmasq as a proxy. This is working for the traditional PC BIOS: dhcp-range=,proxy dhcp-boot=pxelinux.0 pxe-service=x86PC,x86PC: Automatic Network boot from ProBook,pxelinux enable-tftp tftp-root=/tftpboot

[Dnsmasq-discuss] how to track changes for a given hostname

2014-05-30 Thread Olaf Hering
My dnsmasq sometimes forgets the hostname of one of my boxes. I wonder how to track that without tweaking the source? My reconnect script reports: ... ssh: connect to host optiplex port 22: Connection refused rc '255'. root@optiplex @ Fr 30. Mai 11:27:43 CEST 2014 ssh: connect to host optiplex

[Dnsmasq-discuss] question about the host-record= example

2015-11-18 Thread Olaf Hering
I have several host-record=$name,$name.$domain,$ip4,$ip6 lines in my dnsmasq 2.62 conf file. Today I realized that "host $ip4" resolves to just "${name}.", but I was expecting "${name}.${domain}.". So I removed the "$name," part and get now the full name. I wonder why the example in the

[Dnsmasq-discuss] DHCP option 121, handling of interface address

2018-04-27 Thread Olaf Hering
I had to add DHCP option 121 to server an extra network to the clients in case one of the clients has to use USB tethering via the mobile phone. Therefore I added this line, and all is (almost) fine: dhcp-option=option:classless-static-route,$other_local_net/24,$interface_IP But it is not

[Dnsmasq-discuss] lease time affects ipv6 prefix life time

2020-05-04 Thread Olaf Hering
I have this in dnsmas.conf to advertise the current ipv6 prefix: dhcp-range=::,constructor:${interface},slaac,ra-names,64,${lease_time} enable-ra If the prefix gets changed, dnsmasq starts to announce the new prefix, but it keeps announcing the old one (as deprecated) as well for a while. I
