After a quiet couple of weeks we’re back with some noteworthy changes, here are all the details…

LCFG om Utility

The LCFG om component has long had the ability to call an LCFG component method on a remote machine using ssh (e.g. om host.component configure). There is now optional support to allow calling remote methods on a whole list of machines in one go. This will retrieve the list of target machines from a host netgroup with the name of the group being prefixed with an ‘@’ character (e.g. om @mycluster.component configure). The feature is only available for Ubuntu and requires a couple of extra packages, it may be enabled by defining the LCFG_OM_NETGROUP macro for a profile. Note that the functionality of this feature is currently quite basic, it will run up to 5 connections in parallel and there is no support for connection timeouts. It is possible to configure a connection timeout for your ssh client using the ConnectTimeout option in your .ssh/config file.

DNS

The LCFG dns component and schema have been updated to version 18 on Ubuntu. This is just a minor change to a resource name to avoid a clash (srvgen is now srvgenbin).

PostgreSQL

There are new security updates for PostgreSQL versions 16.3, 15.7, 14.12, 13.15 and 12.19. It is important to not that, unusually, there is a manual step recommended. For full details, see the release notes (in particular, the “Updating” section).
