Anyone have recommendations for good in-rack screen & keyboard units? I'm looking at the Dell A7546778 as an example.

I just realized that we locked our WiFi router inside a completely closed server rack.And then been complaining about poor WiFi signal.

We literally locked up our router in a Faraday cage.

I finished transferring allinonlife.com from a shared web host to a VPS just now. Sorry for the site being down yesterday. Now the site should be faster and overall much better since it is on a good VPS. It took many hours of work. #vps #webmaster #sysadmin

Ich habe hier noch so einen #RaspberryPi rumliegen und bin am überlegen, ob ich diesen nicht als #BackUp Server für meine #Proxmox #VMs verwende und zusätzlich noch die VMs mit #Munin und #Monit verwende.
Was meint ihr? Ist mal so ne spontane Idee ohne Konzept.

Vous connaissez celle du #sysadmin qui fait une boulette ? #facepalm

Jusqu'à il y a deux jours, mon serveur hébergeait une instance #Roundup (un bug tracker), que j'ai décidé de supprimer après l'avoir remplacée par une instance #Gitea.

Ce que j'avais oublié, c'est que Roundup permet de soumettre ou d'éditer des rapports de bug par e-mail, ce qui nécessite une petite intégration entre Roundup et le serveur mail, sous la forme de la ligne suivante dans le fichier /etc/postfix/main.cf:alias_maps = hash:/etc/aliases, hash:/etc/roundup/aliasesAprès la purge de Roundup, /etc/roundup/aliases n'existe évidemment plus, ce que Postfix n'aime pas du tout: dans l'incapacité de consulter l'intégralité des tables d'alias (puisque l'une d'elle est manquante), il rejette tous les mails entrant avec une erreur Temporary lookup failure...

Das »Rätsel« war so einfach, ich hab einfach mal den Rest auch »entschlüsselt«. Wenn solche Challenges zu einfach sind, dann wirkt das übrigens auch abschreckend. 🙄

Got to LOVE working upgrades. I have 52 servers to upgrade, but we can only get 4-8 done a night in the window we are provided. Goal: 0 Downtime
This is gonna be a long drawn out process I think. To make matters worse, I was just informed of a death in the family, so I will have to bow out at some point to attend a funeral. Hope the upgrade wont suffer much in my absence.

Uhhh wth #postgres.. it's not success if you didn't accept it. These are being spammed to my not-so-well performing server :/

Server is spiking on IO wait a lot and things get slow. Any postgres experts for some tuning advice? Currently I'm mostly running on defaults, the only thing I've bumped up is effective_cache_size. I tried some other combos like tweaking shared_buffers and such but things generally only get worse. I have 16GB RAM on the server and it is hardly used. The server has 4 cores. I have quite a few apps using this server so lots of connections. Thinking maybe that is the problem?

Yesterday an update to Samba 3.8 totally fucked the chips. I had to spend all day sodding about with it to isolate the wanky components, then I tossed it off on winbindd so it wouldn't be shagged for a week. I'm running out of motherboards to bodge this with.

Welcome to the club @Ben

Diaspora is a great platform with lots of activity. Stick around, give it some time and it will grow on you. The interactions here are far better then anywhere else I have got to.

Here is some more information about this social network.

Welcome to the Federation!


The Federation is a global social network that works by having different computers talk to each other, instead of having one computer having full control over the network and people's data.

So.... I just installed #hubzilla but I cant seem to get it to sync with the federation.
I installed hubzilla using the instructions here: Tutorial
I can get logged into the site, make posts, etc...
If I try to run any of the following commands:
util/config system.diaspora_allowed 1
util/config system.gnusoc_allowed 1
/opt/bin/php Zotlabs/Daemon/Master.php

I am met with the following:

<head><title>System Unavailable</title></head>
<body>
Apologies but this site is unavailable at the moment. Please try again later.

Any advise would be greatly appreciated. I would really like to test out hubzilla due to its interoperability with other services.
You can access the site and create an account if you need to: https://tftsr.com
Otherwise tell me what you might need and I will get it for you. For what its worth, I have installed this on my Synology DS918 NAS.

I am setting up a server which will be a secondary #MX for my domain; it is running #sendmail. I want it to be able to check ahead to the primary MX to see if the recipient is valid, before accepting the mail to relay. This is to reduce the amount of blowback to postmaster@.

On my existing secondary MX (which I'm replacing with this new server), I am using smf-sav, which can do this. However, it is no longer maintained (although I found a fork with updates), and seems a little bit of a kludge to use it only for this feature (I don't want to do sender address verification, which is it's main purpose). Can any #sysadmin out there suggest any alternatives or current best practice?

#Linux <- pretty sure this will help me reach a knowledgeable audience!

Wow, #SystemD journal seems very hungry on #Ubuntu 18.04. Investigating what uses most disk space on one of my 20G disk VM's which is continuously near the limit and SystemD journal is currently taking 1.9G of space.

Is this normal?

#sysadmin

ps. No need to reply with "systemd sucks etc", you risk instant ignore button activation by raising that war again. I don't care if SystemD is good for the world or not, just this specific issue :P

pps. I'm not reinstalling with your favourite linux distro which doesn't have systemd.

Happy SysAdmin Day!

Wait… what exactly is SysAdmin Day? Oh, it’s only the single greatest 24 hours on the planet… and pretty much the most important holiday of the year. It’s also the perfect opportunity to pay tribute to the heroic men and women who, come rain or shine, prevent disasters, keep IT secure and put out tech fires left and right.

At this point, you may be thinking, “Great. I get it. My sysadmin is a rock star. But now what?” Glad you asked! Proper observation of SysAdmin Day includes (but is not limited to):
  • Cake & Ice cream
  • Pizza
  • Cards
  • Gifts
  • Words of gratitude
  • Custom t-shirts celebrating the epic greatness of your SysAdmin
  • Balloons
  • Confetti
  • Did I say gifts

So I went with DNSimple after looking at a few different companies. Initial experience is good, I like their ethos, and their support is friendly. Here’s a referral link if anyone is interested (we both get $5 credit if you sign up).

My DNS is all now managed with #Terraform (this provider), stored in Git, with the Terraform state file in Nextcloud so I can safely edit on multiple machines. They have good APIs so all sorts of automation is possible if that’s your thing (hey, it's 2018 - it should be your thing!).
