• Creating a Virtual Network Interface in Debian

    There are times when you might want to assign more than one IP to a system, even if it only has a single physical NIC. This documentation details how to create a virtual network interface (known as aliasing) under Debian (see here for how to alias in Centos 6).

  • Installing and Configuring KDump on Debian Jessie

    Having kdump enabled on a server provides a number of benefits, not least that in the event of a kernel panic you can collect a core-dump to help investigations into the root cause. It may simply be bad luck, but my experience with Debian Jessie has been that JournalD is absolutely hopeless in the event of a kernel panic.

    Pre SystemD we used to (sometimes) get a backtrace written out to a log, even a partial backtrace could help point investigations into a rough direction, but even with JournalD configured to pass through to rsyslogd those traces just don't seem to be appearing (which to be fair, might be because of the nature of the panic rather than the fault of journald).

    This documentation details the steps required to install and configure KDump on Debian Jessie

  • Installing iRedMail on Debian (Jessie) 8

    I've run my own mail server for quite some time, but it's started to reach the point where a refresh is probably in order.

    Normally, I'd prefer to build from scratch, but I thought, this time, I'd have a look at some of the "off-the-shelf" solutions that now exist. Mailinabox was quickly discounted because there's no real configurability, which doesn't sit well with me (it does simplify installation, but makes long-term management that much harder).

    iRedMail seems to have a reasonable following, and a scan of it's website and documentation suggested that it is, at least, reasonably sane.

    This documentation details the process I followed to install iRedMail on Debian 8 (Jessie). I used Jessie rather than Stretch (9) because that's what the VM I was repurposing was imaged with.

  • OpenVPN on Debian

    Setting up OpenVPN on Debian is as straight forward as on CentOS, though some of the file locations differ slightly.

    This documentation details how to install and configure OpenVPN on a Debian server.
