While brushing up my resume, I am seriously considering #freelancing full time again. I haven't done that for the better part of 15 years. What does that landscape look like now in the realm of #devops, #sre #programming, #linux, #sysadmin, #netadmin, and #infosec?

Back in the day I was using several freelancing sites but I suspect those have turned into a race for the bottom. Mastodon is also my only social media presence. I don't know what's popular these days.

I need to do some research

Si ça continue, nous bloquerons Azure, AWS et consort 😡

Je ne comprends pas ces gens qui ont une boîte remplie de vieux câbles et adaptateurs. Moi perso, j’en ai trois. #netadmin

C’est un peu des bourrins les robots des voleurs de l’intelligence artificielle, ça tape plusieurs fois par seconde.

J’ai bien tenté d’ajouter des entêtes X-Robots-Tag

…mais ils n’en ont rien à faire, qui aurait pu prédire.

Je suis donc passé à l’étape suivante « block-user-agent » :

Ha ben je comprends pourquoi je n’arrive pas à suivre correctement @laelia_ve, mon admin du boulot me dit que la résolution DNS se fait avec un serveur chinois qui est bloqué par décision du RSSI

The second edition of Networking for Systems Administrators is in progress. Just as the NIC is where the server meets the network, TCP/IP is where the sysadmins meets the netadmins. I'm writing this book to end the feud between these two teams.

If you'd like this book to happen, you could sponsor it. https://www.tiltedwindmillpress.com/product-category/sponsor/ -- 13 more print sponsors and I have to do another challenge coin!

What are people using these days for Netflow/IPFIX collection and analysis? #sysadmin #netadmin

(Yes, yes, I wrote "Network Flow Analysis," but it's IPv4-only and flow-tools is not extensible to IPv6, plus that was fifteen years ago and life moves on.)

Anyone know how to get Comcast Business to assign a reverse DNS (PTR) entry to one of your organization's static IP addresses? I've now spent an hour or more on the phone with support and they still haven't done it (despite escalating it up to "advanced support" - then summarily closing the ticket). In the distant past, I remember making this request via email, but I can't find any way to do that now (since I'm again forced to deal with #Comcast).

Addendum: after opening a new ticket and pleading with the phone support rep, they escalated it and it got done. Still wish I could just email (I couldn't even see a way to open a new support request online).

How long do you let DHCP leases remain unrenewed (dynamic or static allocation)? Since my entire network is static DHCP, but a reboot of that server wipes its known DNS (I'm working on it), and it's a small home network, I'm in the < 15 minutes camp, and will ratchet down if I know I'm making a major change. Work is usually around 60 when I control it. #sysadmin #netadmin

hello people, planned network maintenance this Wednesday from 0000-0300 AEST as i do firmware upgrades on our core arista routers in the datacentre, hopefully its not too long, being an ISP im leaving a number of people without internet for a little bit lol

Any idea why SCTP protocol never really took of ? It looks like it could easily take over TCP (and potentially UDP) with lot of benefits.

Hot season tips: Lowering the TX power on your Wifi access points will decrease a lot the power consumption, generated heat, and increase the lifetime of it, with most of the time no performance impacts. (I run mines at 1/8 power with no performance loss)

Par contre, pour faire de la supervision de service à la nagios c’est plus limité :blobwhistle:
