switching to dnsmasq when using grml-terminalserver
Dear All,
Is it possible to replace isc dhcp server with dnsmasq for use with grml-terminalserver? There is an existing dhcp server in my environment that I cannot touch and therefore I need to set up a proxy dhcp server for distributing only pxe-related files but not ip addresses like this: https://www.theurbanpenguin.com/pxelinux-using-proxy-dhcp/ Dnsmasq can do it but isc-dhcp-server does not seem to have this option. Thanks!

Well, you can of course use dnsmasq instead of isc-dhcp-server in your environment. But if you're asking for out-of-the-box support within the grml-terminalserver user interface, then that's something someone would need to implement yet. :)
I'm not *yet* sure we'd want to use dnsmasq instead of isc-dhcp-server by default, this would need some further research regarding possible drawbacks, package dependency changes,.... One of the major drawbacks of dnsmasq IMO is, that you need to pretty much always *restart* it - instead of reload without real downtime - for most of any config changes, like adding a new host. This shouldn't be much of a problem for grml-terminalserver itself though, while the proxydhcp feature sounds like a good argument in favor of dnsmasq for grml-terminalserver. Any further opinions?

if we could see a use case explained with details, it will be more easy for opinions. regards.
