Java RMI service finderprint?

[Gabriel Lawrence <gabriel.lawrence () gmail com>]

Folks,

I'm looking at finding different Java RMI servers on my network.

With some help from Brandon we put together this fingerprint:

##############################NEXT PROBE##############################
Probe TCP java-rmi q|\x4a\x52\x4d\x49\x00\x02\x4b|
rarity 7
ports 1024-65535

match java-rmi m|^\x4e\0[\x00-\x0f]([0-9.]+)\0| p/Java Remote Method
Invocation/ i/Client IP: $1/

But, I noticed that these already existed:

##############################NEXT PROBE##############################
Probe TCP JavaRMI q|\x4a\x52\x4d\x49\0\x02\x4b|
rarity 8
ports 706,1098,1099,1981

match jrmi m|^\x4e..[0-9.]+\0\0..$|s p/Java RMI/
match jrmi m|^\x4e..([\w._-]+)\0\0..$|s p/GNU Classpath grmiregistry/ h/$1/

There really isnt a well known port for Java RMI. So... I'm wondering what
history there is for the choice of ports and if its possible to open up the
idea of expanding these to look at all the non-priv ports.

Thanks,
gabe
