Still, I have a hunch that it is possible to do better (though it might be because of me not having thought about some use cases). For example, is there a reason to run the following command? sudo /usr/sbin/dnsmasq --port=0 "--dhcp-range=192.168.1.0, proxy" " --dhcp-boot=pxelinux.0,saucisson" --enable-tftp --log-dhcp In my understanding, the --pxe-service switch is required in such a situation (as you correctly deduced, that is a situation where another DHCP server is running), or there is some other problem in the command. If so, dnsmasq should say it. But I certainly could be wrong, being no expert in net booting. > > Cheers Thank you for your interest and time. -- Olivier > ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
[Dnsmasq-discuss] Please consider clarifying the man page about the tftp service
Dear list, I have been happy to use dnsmasq to install debian through network boot. However, it has taken a lot of trials and errors before I found the correct command line to use. I’d like to report my experience in hope that the man page be possibly improved, as the developers see fit. It was very unclear to me while reading the man page which options exactly need to be turned on to enable network boot. I tried the following commands: sudo /usr/sbin/dnsmasq --port=0 "--dhcp-range=192.168.1.0, proxy" " --dhcp-boot=pxelinux.0,saucisson" --enable-tftp --log-dhcp sudo /usr/sbin/dnsmasq --port=0 "--dhcp-range=192.168.1.0,proxy" " --dhcp-boot=pxelinux.0" --enable-tftp --log-dhcp --tftp- root=/home/olivier/netboot sudo /usr/sbin/dnsmasq --port=0 "--dhcp-range=192.168.1.0,proxy" " --dhcp-boot=/pxelinux.0" --enable-tftp --log-dhcp --tftp- root=/home/olivier/netboot --dhcp-no-override before I finally found a correct one: sudo /usr/sbin/dnsmasq --port=0 "--dhcp-range=192.168.1.0,proxy" " --dhcp-boot=pxelinux.0" --enable-tftp --log-dhcp --tftp- root=/home/olivier/netboot "--pxe-service=x86PC,Install Linux, pxelinux" (All this took a while because I did not even know the TFTP service was not activated with my first tries, so I thought the problem lied somewhere else.) The man page says: “If dnsmasq is providing a TFTP service (see -- enable-tftp ) then only the filename is required here to enable network booting.” and also reading about the pxe-service option, I thought that it was unnecessary and was there just to allow for customizing the string that would display at start (which I thought I do not need). Please consider clarifying the man page concerning the relevant options to state which option is required exactly; and especially, please consider making dnsmasq tell something in the log file, or (better IMHO) refuse to start when the options it receives are incoherent. With the current behavior, it is very hard, when it’s the first time you do it, to even know that dnsmasq is not configured properly. -- Olivier ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
