System maintenance

The Elflord
Silly stupid scenario where I'm peeling one webserver/mail server offline to be upgraded (reinstalled really). However peeling the front end reverse proxy ended up causing a lot of random "000" nginx errors. I've rebooted firewalls, VMs, triple checked configs, nothing would show up. Eventually I took a punt at the…

ESXi 6.7U3 Update issues

The Elflord
ESXi 6.7U1->6.7U2 update introduced a "Not enough space" error when running the CLI level update. This appeared to have been carried across to the ESXi 6.7U2 to 6.7U3 updates. This is because one vib is just too large for it to install. The solution is to update one VIB then…

Personal Control Panel

The Elflord
I have been working on my own personal control panel for a while, integrating all sorts of random API, stats, and stuff - like a proper NOC except for home. One of the latest additions is the financial module, with Crypto Currency in it. Just got the status up and…

puppet fun

The Elflord
Starting to get into more puppetizing the 'production' servers - but then this means some things break more often. Currently gotten a nice nginx setup which creates configurations based on a heira file. Also, thrown in is mod_security, and a customized PHP 7.2/7.3 script - per site in PHP-FPM mode.…

Reinventing DevOps/SysAdmin (Intro)

Initially just a fad (and still sort of is, as a "terminology"), it is pretty much summarized to me as System Administrator, with a lot of provisioning automation specialist stuff. The System Administrator (now "Systems Engineer") is mainly a maintainer role…

Changing servers again

The Elflord
It's sad to keep switching server due to hardware failures - even on the cloud. I've moved it back to a private server (slow bandwidth) for a short while - back to the cloud again now. Expecting more migrations to happen in the next few days. Mail was up, now…

Migrating to Cloud

The Elflord
Yes, a lot of disruptions. After lamenting over the state of the Australian NBN (Fraudband) - and realizing it would take 4 days to just copy my mailserver up, I've decided to drag it all to a hard disk and bring it to somewhere where I can upload 10x the…

Faerie.CX goes back to the Cloud

The Elflord
Yes, I broke down on costs and stuff - and decided to get a hosted server :) Cost me a mint, but still a good deal from my old folks I used to work for (Web24). Too bad for our backwater Australian Internet (read:ADSL2+) for the really slow uploads. Having…

Quick roundup for Mar-Apr

The Elflord
Packages of note in the Internet worlds: pfSense (2.3 release) Runs off Bootstrap front end now, FreeBSD to 10.3 base. Looks very 'slick'. I did break the upgrade, cos the 'RX-offload' bug with Xen still exists in this release. Has to be turned off from the host. Code snippet given…
