Thread:Extension talk:Lucene-search/Help - port 8123 refusing all connections after Linux update & reboot/reply (11)

I just had the same problem after moving some wikis and lucene to a new server.

The solution: lsearch-global.conf contains the hostname. After changing it to the content of $HOSTNAME, it works again. Interestingly, on the old server I had to use the full hostname (hostname -f output) while the new server needs the short hostname (hostname -s output).

This is "just for the records" in case someone hits the same problem ;-)
