Now that my fight with bgp is over, I have a #linux#networking question for you. A bridge interface is pretty much a sowtware representation of a switch, with one of its ports connected to the linux host. Now, that one port will be DOWN if no other interface is enslaved to that bridge, meaning you can't e.g. run a dhcp sever on that bridge (kea stubbornly refuses to operate on a downed interface; I don't blame it).
I had a few discussions with @oleksandr and he suggested to plug a veth into my bridge. Well, now it's always up (because there's always something plugged into it), but it feels like I use up two ports of the switch by the same machine. It's slightly confusing as to wether I should use the bridge interface or the veth interface. In practice it seems that removing all ip addresses and routes from the bridge and only using the veth would work, but it also seems excessive. Should I just enslave a dummy0 into the bridge so it goes up and use the bridge interface instead?
How do you people solve the problem of needing to have the bridge up before anything is enslaved to it (i.e. running dhcp, dns and such on the bridge interface while no VMs are up, yet)?
So if you are looking for a #Python network diagnostic utility (command line), something you can run on a laptop when doing common troubleshooting for misbehaving networks, what are some features you'd like to have?
Thus far I'm thinking
IP
link speed
neighbor data via LLDP (to know what port a given outlet is plugged into)
I want to build / get a travel router / hardware VPN which connects to a network wirelessly or via RJ-45 and creates a new Wi-Fi (& maybe a wired connection to the new network) to which I can connect my devices and everything gets tunneled either through Mullvad or through my home network. Maybe it can even throw the traffic into Pi-hole before tunneling.
What hardware would I need? (As compact, as cheap-ish and as efficient as possible)
Dear fedi, today I'm looking at self-hosting (webserver, family nextcloud,...) from our home.
Situation: I got a big fat fiber entering the house and my isp provides both fixed ipv4 and ipv6coming in through a fritzbox. Behind that is an asus router for the home lan/wifi that has all boxen connected (nas, osmctv, laptops, phones) connected.
I'd like to properly secure this setup (modify if needed), exposing some services transparantly (!) for family members on the internet (notably nextcloud, maybe others), i.e. not changing configs on phones or laptops when outside the home.
How do I go about this? Can you share good (pref non corpo, no commercial solutions) blogs & guides to get me on the right track? Good pointers as well (I'm comfortable on the linux cli, scavenging manpages and sandboxing/testing stuff in containers/vm's). I'm mainly looking for good pointers on networking, routing, firewalling I guess..
How to Make a Business Card, According to Claire ✨
Had the energy to bust out this little tutorial this morning. I often get comments on my business cards, and I have a lot to share about how I got to a place where I make really great ones.
"In the mid-1960s, Robert Kahn began thinking about how computers with different operating systems could talk to each other across a network.
[...]
It is for this work on packet communication technologies—as part of the project that became the ARPANET and in the foundations of the Internet—that Kahn is being awarded the 2024 IEEE Medal of Honor."
I need a new 2.5gbps router to stick between my ISP's modem-router and my own network. Something with proper device management, port forwarding, IP bindings, being able to name devices myself instead of seeing "unknown device" and a MAC address etc
OK #LInux my home internet has been down for 30 hours and my ISP #GigabitNow seems incompetent to fix it.
#Networking seems barely alive so I'm hoping if I give you all some details, you can give some ideas of more tests to run or settings to try, so I can help pinpoint the issue to the best of my ability from my side.
Introducing renet2, a fork of the networking library renet that implements the game-oriented netcode standard.
Highlights:
Allow netcode servers to manage multiple data sources at once (e.g. UDP sockets and a WebTransport server).
Add built-in in-memory sockets and WebTransport sockets. You can now run a netcode server with native AND browser clients, with the same exact authentication workflow for all clients (using ConnectTokens).
"IPAM error: failed to find free IP in range: 10.89.0.1 - 10.89.0.254"
/run/user/1000/netns contains 257 netns-* files.
The thing is: ip netns list shows nothing, and podman network rm does not fix the issue. Rebooting probably will, but that's the Windows way of solving things …
What? A network utilities management tool (for YAML config files) developed for 7 years.
◉Way back mainly for enterprise cases where network configurations required to be copied across hundreds of workstations in a whiff
◉Ifconfig can be used as always via nettools - this is extra for specific needs - not a replacement for network-manager
◉Simultaneous WPA2 & WPA3 support
another on-premise bare-metal cluster build for 2024!
greater than five but fewer than ten Ampere Altra Q80-30 servers will be combined with Xeon based hosts of mostly-equivalent specs (dual-socket 8280 and E5-2697v4 hosts), 768GB - 1TB of RAM per each, and NICs w/ multiple 10, 25, and 100GbE ports depending on system role. switches are all Arista.
I need to set up Wi-Fi in a small business, but not allow any streaming services. Ideally, with the ability to turn off guest Wi-Fi after hours so the residential units don't use it all evening.
The router that comes with the Internet service sucks, as they all do.
First part of a new long term home project coming in. An #Ubiquiti PoE+ switch to power a small #Kubernetes cluster built using #raspberrypi nodes. Going to blog about every step once it has been completed. But it is going to be a few quarters long project doing bit by bit
