I just published 0.9.0 version of logmerger, compatible with Python 3.13. Here is an example merge of a client and server log, plus PCAP packet capture file showing TCP send/receive traffic. Uses textual TUI framework for cursor and mouse interaction in a terminal session. https://pypi.org/project/logmerger#python#tcp#networking#textual
Is there any text-based, ideally distributed monitoring software out there? I want a TUI that shows me (e.g. with green/red highlights) the reachability of hosts (simple ping checks) while I'm doing network maintenance. Like a really simple, curses based nagios? It would probably look like a bloomberg terminal.. (I know this wouldn't be too hard to implement.. but I can't really believe it's not already out there...) #linux#TUI#monitoring#network#networking#sysadmin#software#curses
Wrapping up an incredible time at Casino Beats in Malta! We've had amazing conversations, built great connections, and are leaving energized for the future. Thank you to everyone who made this event unforgettable. Until next time!
Wednesday 5th June, 9 am CEST, is the new deadline to apply for the role of GÉANT Chief Executive Officer (#CEO).
The CEO will be based in Amsterdam and will be entrusted with the dual responsibilities of overseeing GÉANT’s day-to-day operations and guiding the long-term strategic direction of the organisation.
I just wasted about 2 hours of my time trying to figure out why a server would only connect at 100Mbit instead of the expected 1Gbit.
I had all sorts of ideas, NIC, driver, driver settings, switch related ... and in the end, I almost don't dare to say it, it turned out to be a cabling problem ... you know, there's a tiny little difference between a Cat5 and a Cat5e cable ...
Who the heck still has Cat5 patch cables lying around?!! ... me, for example 😱 but one less now!!
Whenever I have an internet problem I always dread contracting my ISP because I have to explain what I’ve done to the repair tech and I can tell I’m annoying them.
Like my fiber box is getting no signal, so I reach out and they’re like “we’re going to reset your router”. Except they can’t, because I don’t use their router I use my own router and trick their system into accepting it because I’ve tagged the port with the cable from the fiber box with the right VLAN. So then after I explain that part they’re like “ok well can you hook up our router for testing?”
I can but I also have an old fluke fiber tester that I’ve already tested the line with so like…..I know it’s not that. But then I have to explain “well I actually already tested the actual fiber and there is no signal so the problem isn’t with the router. Here’s the output of the test.”
I feel like it must be like an ISP techs worst nightmare to get a fluke test output in a service ticket.
Okay, I didn’t expect #5G to actually make a difference sub-6GHz. But here we are, with the fastest Speedtest I ever had on a cellphone.
Btw, this was inside a mall and I don’t even know where the tower is. #networking#internet

Spread the word and let's make network troubleshooting easier for everyone!
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.
