Subject: prevent PC92 A/C changing our $my(alias|call)
X-Git-Url: http://scm.dxcluster.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=a24cc09d8262093df92c767d3010c0a5fd6e42d7;p=spider.git

prevent PC92 A/C changing our $my(alias|call)

It appears that some nodes are getting knickers in a twist in their
routing tables and causing routes and thus $my(alias|call) file types to
change. Prevent this from happening.

    $clusterport. This is really only of use for people trying to run more than
    one instance of DXSpider on the same machine.
 2. Fix who command to make RBN connections as RBN and not USER.
+3. Prevent other nodes claiming that $myalias or $mycall is a different type
+   (user or node) from changing our route table and thence the user type.
