I am reopening this old topic. We added a probe for detecting quake3-master servers. We decided we should not add another probe for detecting Dpmaster as it is just a specific implementation. I am thinking of writing a dpmaster-version script that would run against quake3-master servers, and check whether that server is Dpmaster or not. Does this make sense? With the script we do not need to add probes that get sent against all targets. Instead we can only run version detection against ports that have already been identified as quake3-master.

I put the v/2.0/ as I could not figure out a convention for stating "or later". Feel free to change that as you see fit. You can use nmap -sV -p 27950 -sU -Pn master.urbanterror.net master.quake3arena.com to test the probe. master.quake3arena.com does not support the feature, but master.urbanterror.net does. Also master.urbanterror.net did not know about the game I am using in the probe while I was testing it, so it is a good test candidate.Hmm, I'm not sure that this is an important enough protocol to have two different version probes. Especially as the second probe is only to distinguish one particular implementation that is already matched (generically) by the first probe. One one hand, this only affects a couple of ports by default, but on the other, it will slow down everybody's --version-all. I know I'm the one who suggested dpmaster detection, but I'm inclined not to include this probe unless someone thinks differently. David Fifield
