2½ Stunden debuggen (bis 4 in der früh), weil meine Docking Station Amok gelaufen ist und das Netz gekillt hat. Und da war nicht einmal ein Rechner dran.

Wer kommt bitte auf sowas, oida?!

Nueva Entrada en #H4ckseed - Administrador de redes: funciones, habilidades y responsabilidades

A la par que crece la demanda de especialistas en tecnologías de la información, también lo hace la necesidad de profesionales en el rol de un administrador de redes. Las organizaciones requerirán cada vez más expertos dedicados a gestionar sus redes y sistemas informáticos.....

Take troubleshooting further than connectivity checks. Gain skills in filtering, interpreting, and analyzing network traffic to solve performance problems, detect malicious activity, and explain findings clearly.

Covers IPv6, SMTP, wireless, malware, and more.

Forward traffic to a jailed web service:

bastille rdr TARGET tcp 443 443

Secure HTTPS passthrough made easy.

#FreeBSD #netadmin #firewall

currently fighting a very bizarre issue with #proxmox where the guests get terrible download speeds and a not as terrible upload speeds but the host has a full bore 10gb duplex. i'm talking like 7mbps down on the hosts and 600..ish mbps up.

if i had any hair left i'd be pulling it out...

Bastille 1.0 is full of great new features!

Say hello to the new `bastille network` command! View, inspect, and troubleshoot jail network interfaces and IPs from a single place.

#netadmin #BastilleBSD #FreeBSD

Want insight into your jail network? BastilleBSD supports NAT, VNET, and loopback isolation for granular control. Powerful, portable jail networking. #FreeBSD #netadmin

Network masters, rejoice: BastilleBSD supports loopback‑only, alias, NAT, VNET, VLAN & bridged modes, auto-configuring bridges and epairs. Full network flexibility! #FreeBSD #netadmin

Jails can do more than you think. BastilleBSD supports VNET jails, NAT, loopback-only configs, and more. Network your containers with precision. #FreeBSD #netadmin

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

"Every time I launder my undies, the washing machine complains that I’m thwarting its dream of joining a global botnet."

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.)
