Rspamd, bayes expiry and Redis – ERR Number of keys can’t be greater than number of args

I recently enabled the bayes expiry module (https://rspamd.com/doc/modules/bayes_expiry.html) in Rspamd and found myself staring at the following error in the Rspamd logs with no idea what it meant: lua; bayes_expiry.lua:332: cannot perform expiry step: ERR Number of keys can’t be greater than number of args The only reference that I could find to this online was a single post on...

SQL Server 2008 R2 upgrade and INSTALLSHAREDDIR/INSTALLSHAREDWOWDIR

I recently found myself trying to upgrade an old SQL Server 2008 R2 instance to SP3 so that it could in turn be upgraded to SQL Server 2014, but quickly ran into problems with the following error message: The INSTALLSHAREDWOWDIR command line value is not valid. Please ensure the specified path is valid and different than the INSTALLSHAREDDIR path. At...

Decrypting an APFS volume from the Terminal

I’ve been playing about with a Hackintosh desktop running High Sierra, but run into an interesting problem – the FileVault Preboot loader which asks you for the password to decrypt the APFS volume doesn’t recognise the USB keyboard by default. Apparently there are ways to fix this by building the necessary drivers and inserting them into the Preboot volume, but as...

Building Bareos RPMs on Ubuntu 16.04

Following on from my previous post on how to build Bareos (Backup Archiving Recovery Open Sourced) RPM packages on CentOS 6 & 7 (https://www.spheron1.uk/2018/03/14/building-bareos-rpms-on-centos-6-7/), the following instructions will show you how to build .deb versions of the packages on Ubuntu 16.04. Again, these instructions are based on Bareos version 17.2.5, so would need to be adjusted appropriately for other versions...

Building Bareos RPMs on CentOS 6 & 7

Bareos (Backup Archiving Recovery Open Sourced) is a popular open source backup system originally forked from the Bacula project, but they only publicly publish packages for the first release of each major version; updates are reserved for paying customers. The source code is available on GitHub however, so you can pretty easily build your own packages, even if exactly how...

WHMCS and Nominet EPP farce (again!)

On the 14th of January 2016 Nominet notified EPP users that they would be upgrading their EPP system to require TLS version 1.1 or higher connections on the 8th of June 2016 in order to keep the EPP system secure. From the 2nd of February 2016 the Nominet EPP testbed was updated to reflect these new requirements so that registrars...

CSF bugs and updates

ConfigServer Security and Firewall (CSF) is a great program for managing iptables/netfilter firewall rules on Linux servers and performing automated blocks based on various things such as brute force login attempts (check it out at http://www.configserver.com/cp/csf.html) and I really shouldn’t complain given that it’s free, but sometimes I really do wonder if ConfigServer/Way to the Web actually do any testing...

ValueError in Django migration

I’ve recently started developing in Python+Django again for a personal site that I’m working on and for far too long today I’ve been pulling my hair out when trying to write what should be a fairly simple migration using migrations.RunPython() to generate a default value to assign to a new OneToOneField column. The rather confusing error message that I was...

Cumulus attacks on Juniper (again)

I have a lot of time for Cumulus Networks – I think they’re doing some very cool and unique things with their Cumulus Linux operating system for switches and they genuinely have something different to offer, but when they publish blog posts like their one today (https://cumulusnetworks.com/blog/junipers-second-run-up-the-open-networking-mountain/) I lose a lot of respect for them. This seems to be nothing...
