From: Aleksander Mistewicz Date: Tue, 29 May 2018 09:20:44 +0000 (+0200) Subject: Add dryadAddress and sshAddress to Register X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1a9e53461bbde08e3c2235d07c2c89d8731d16a7;p=tools%2Fboruta.git Add dryadAddress and sshAddress to Register When running multiple dryads on a single host or behind NAT, they must listen on different ports and inform boruta about this fact.
