Description Michal Karm Babacek 2014-08-14 10:22:38 UTC
Title: Configure a Tomcat Worker Node

Describe the issue:
One can take advantage of Apache HTTP Server advertising via UDP multicast. On most systems, this is not allowed by default. One has to tweak the firewall to allow multicast UDP on certain ports.

Suggestions for improvement:

Copy procedures 11.34 and 11.35 to relevant locations in the EWS docs:

Waiting to hear from Michal on other bug where the proposal is to exclude this content for this release since this issue was discovered fairly close to GA. If that proposal is not acceptable, we can implement the additional procedures on Monday.

Comment 2 Michal Karm Babacek 2014-08-15 06:24:59 UTC
Dear Misha,
I don't think this BZ is related to the BZ 1130113.
IMHO, you can safely copy-paste these firewall config snippets from the EAP documentation.

Comment 3 Misha H. Ali 2014-08-15 06:27:07 UTC
Ok, thanks for the clarification, Michal.

Comment 5 Michal Karm Babacek 2014-08-18 09:45:07 UTC
> Procedure 7.3. Configure the Firewall on Red Hat Enterprise Linux 7 to Allow mod_cluster Advertising

Looks O.K. to me.

Comment 6 Michal Karm Babacek 2014-08-18 09:45:49 UTC
> Procedure 7.2. Configuring Firewall on Microsoft Windows using PowerShell

is fine as well.

Thank you very much for this last minute effort.
