[JBoss JIRA] (MODCLUSTER-3) Mod-Cluster event listener for JBossWeb lifecycle and deployment events

by Michal Babacek (JIRA)

That is, server start/stop, connector start/stop, deployment/undeployment of contexts. > Current plan is to use the existing ClusterListener the JBossWeb team has created for standalone JBossWeb.

[JBoss JIRA] (MODCLUSTER-417) Obfuscating jvmRoute as to hide topology

by Michal Babacek (JIRA)

[ https://issues.jboss.org/browse/MODCLUSTER-417?page=com.atlassian.jira.pl... ] Michal Babacek closed MODCLUSTER-417. ------------------------------------- Closing. Clean-up. > Obfuscating jvmRoute as to hide topology > ---------------------------------------- > > Key: MODCLUSTER-417 > URL: https://issues.jboss.org/browse/MODCLUSTER-417 > Project: mod_cluster > Issue Type: Feature Request > Security Level: Public(Everyone can see) > Components: Native (httpd modules) > Affects Versions: 1.3.0.Final, 1.2.9.Final > Reporter: Radoslav Husar > Assignee: Jean-Frederic Clere > Priority: Minor > > Feature request from https://github.com/jmcabrera > Hello guys. > First of all, this is a feature request and not a bug. > I would like to "obfuscate" the jvmRoute so that an external attacker cannot "guess" the topology of my internal infrastructure. > The "strong" way would be to have a symmetrical cipher with a configurable key. > mod_cluster could then cipher the jsessionid before exposing it to the external world, and decipher it to recover the jvmRoute and properly redirect the request. > But I guess that this would have very undesirable consequences on performance. > The "weak" way would be just obfuscate, i.e. let's say that the jsessionid is alea + '.' + jvmRoute. We could take a part of the alea to alter the jvmroute in a reversible way (XORing for instance). > Anyhow, the expected effect would be that the jvmroute would be externally different for each and every request. > Unfortunately, I have close to no C skills, hence I cannot make this myself. > (as a side note, coming from mod_jk, I'm quite impressed by the features mod_cluster offers! Thanks for the good work :) ) -- This message was sent by Atlassian JIRA (v6.2.6#6264)

[JBoss JIRA] (MODCLUSTER-404) ModClusterService stop commands are always draining sessions
