Subject Re: Solr replication 1.3 issue
Date Tue, 22 Dec 2009 22:33:05 GMT
This is a Unix security question. "rsyncd' is a system daemon and
should be managed in the OS scripts. The rsyncd-* scripts include a
security setting for the 'solr' account that limits the account to the
solr data directory (and this code does not support multicore).

For security reasons, I personally would not make a sudoer out of a
user with an automated remote login; but every site is different.
