SUSE Multi Linux Manager Salt API java exception - ipv6
This document (000021740) is provided subject to the disclaimer at the end of this document.
Environment
SUSE Multi Linux Manager 5.0.2
Situation
Symptoms include SUSE Multi Linux Manager 5.0.2 deployment complications, such as not being able to generate a self-signed certificate for a SUSE MLM proxy resulting in the error:
ERROR: redstone.xmlrpc.XmlRpcFault: unhandled internal exception: com.suse.salt.netapi.exception.SaltException: java.net.ConnectException: Connection refused
Also possible are complications with bootstrapping a minion, such as in the MLM webUI you may not see a minion that has been bootstrapped. You can confirm a salt key has been accepted and that a minion can be targeted with salt commands via CLI, but the minion system and the salt key do not display in the MLM user interface.
Resolution
To resolve this issue, edit the container host (NOT the MLM container) /etc/hosts file, removing the IPv6 entry for localhost:
Before:
::1 localhost ipv6-localhost ipv6-loopback
After:
::1 ipv6-localhost ipv6-loopback
Cause
This is a known bug with this version of SUSE Multi Linux Manager and localhost for IPv6 not resolving properly.
Additional Information
Similar to bug bsc#1230865
A fix for this was released in SUSE MLM 5.0.3.
