[Dxspider-support] Ubuntu 9.04 - console.pl

[Gordon Stewart]

Hi Dirk,

DXVars.pm was:-
$clusteraddr = "localhost";

and I have changed it to :-
$clusteraddr = "127.0.0.1";

I have removed the # in my /etc/hosts file and restored it to its 
original condition.

And yes both the console and client are still working nicely.
Re-booted PC and both still starting up ok.

Yes I did have 127.0.0.1 localhost in my /etc/hosts file.
Yes "libio-socket-inet6-perl" was installed by default.

So just changing the DXVars.pm entry from "localhost" to "127.0.0.1" 
appears to have resolved my Console startup problem.
