Bei mir dreht sich der Magen um wenn ich das lese. MTU die stellen Kriegsmaschinen her, Motoren für Panzer etc.. Gefangene in Bayer müssen für diese Firma Teile fertigen, #Zwangsarbeit.

Da bekommt wird die Kombination aus Militärisch-Industrieller-Komplex und Gefängnis-Industrieller-Komplex in 2 Farben gleichzeitig angeleuchtet.

@apangona also make shure you ain't forced on some horrible #IPv4 / #IPv6 #NAT + #PAT scenarios like #4in6 or #4over6 that may provide additional issues and/or packet size increases.

Such cases do caused high CPU load on #Freifunk routers which had to constantly fragmentate and defragmentate packages due to #MTU mismatches (?between WIFI / LAN & WAN, effectively reducing their bandwith to ~ 16 MBit/s max, as they tunnel all traffic via #OpenVPN...

Manchmal komme ich mir vor, wie Anfang am Anfang 1990er Jahre, als man um jedes kB vor der magischen 640kB kämpfte.
Heute durch Zufall entdeckt, dass auch andere magische Grenzen leicht verschiebbar sind.
#MTU minus pppoe jetzt trotzdem 1500 🥳

Guess whats hard to find out if you want to link together some remote workers via vpn? Yeah #mtu of course. I had to set the cluster machine mtu down to 1400 (below the 1420 for wireguard) to get things to work. Again learned some now stuff around networking. I'm really gratefull OKD handles mtu transitions so well. #homelab #networking #wireguard

Ein toller Tipp. Ich war hier schon am verzweifeln. Scheiß #ubisoft soll pleite gehen.

City of Oakland, Irish and Israeli universities suffer ransomware attacks

#technews #ransomware #oakland #mtu #Technion

Munster Technological University #MTU, gets an injunction against the #Ransomware gang that has stolen and encrypted data on staff and students.
https://www.rte.ie/news/courts/2023/0211/1356002-mtu-it-breach/

Something similar happened after the #HSE Ransomware incident back in 2021.

These injunctions would have absolutely zero effect on the actual perpetrators, so I'm scratching my head as to what is the point of them? Is this some kind of Irish Solution to a Russian problem? :blob_confused:​

@GossiTheDog does any other jurisdiction do anything like this?

Was the Munster Technological University (#MTU) ransomware incident attributed to any group as yet?

On the routed Internet you'd run into lots of intermediates on any route not accepting large packets which would make it infeasible to ever pass such traffic. Triggering Path MTU Discovery latency hell dances.

Larger packet sizes can also increase buffering needs at every hop and increase overall latency and jitter for all traffic.

Enter wireless. Wireless tends to prefer small packets. 802.11 has a maximum MTU of around 2300. Mobile networks like 5G and LTE often use something closer to 1400.

So even if you want it and get a few parties to configure their systems for it, it'd be practically unusable for a very very long. I doubt the motivation is there. It doesn't save much outside of a well controlled wire/fiber enterprise intranet.

The SDN / VXLAN Proxmox saga continues...

After posting this I noticed some strange behavior. I was getting ping packets fine and nmap was showing the https service for my new firewall. The problem was when I would navigate to my new firewall management site it wouldn't work. I would get ssl_error_rx_record_too_long on firefox and timeouts on Chrome.

I opened up Wireshark and noticed the return traffic for SSL was severely delayed and appeared malformed.

What I missed in my instructions is that VXLAN takes up 50 bytes for encapsulation, so for the endpoints within the internal network I had to set a custom MTU of 1450 so that the VXLAN encapsulation could happen within the 1500 limit of the interface.

After configuring this on one of the internal machines and it worked to get to the site I thought maybe I had to also configure the 1450 MTU on the firewall's internal interface. I did that and was immediately getting some rapid connect and drops on my home network so I reverted that change. I really don't know why changing the MTU on the internal interface of the firewall would cause that on my main network but it did, so I reverted it. It seems any device on that internal LAN will need the MTU change other than the firewall, for all the traffic to work properly.

Now it looks like the next thing to do is to start putting various machines behind the new routers to start segmenting my lab network, and get it off of the flat network for increased security and traffic isolation and control.

The Proxmox guide I linked earlier will give more details on the 50 byte allocation for VXLAN.
