CIRCLE WITH A DOT

Yesterday I led a half-day workshop for a group of high school students. The content was purely practical: a lot of labs and hands-on exercises and challenges about computer networks, #networktrafficanalysis and #cybersecurity.Girls made their own Ethernet cables to connect to our lab network. Then they analyzed common network protocols and their privacy issues and how the browser settings can affect the amount of sensitive information in the network traffic.Pro tip: together with HTTPS-Only Mode in all windows, also enable DNS over HTTPS using Increased Protection or Max Protection.Pro tip 2: even with those hardened settings, it is often possible to see which websites the user visits, because of TLS SNI or TLS CertificatesAfter that, the girls had the opportunity to try CTF-like activity in the lab network full of old #MikroTik and #Ubiquiti devices and virtual machines with various services exposed.A little bit off-topic: This was the first workshop I completely led using my old #ThinkPad with #FreeBSD #MayTheSourceBeWithYou#PCAPorItDidntHappen #education #womeninstem #womenintech #SecurityGirl #AjTyvIT #wireshark #CTF #handsonlearning #learningbydoing

The #MikroTik TikApp is now also available on #FDroid via our own repo: https://fdroid.link/#https://cdn.mikrotik.com/fdroid/repo?fingerprint=78C22C6CB2A014F57373A10D15FB5AA68D64A94C8DF0E4F56C3C04914D73B9B1From: @fdroidorghttps://floss.social/@fdroidorg/116086115016017602

@ij My Suggestion would be: Start with the Setup of the documentation, but replace Ethernet Ports with sfp Ports. Then- replace MLAG Peer Port with Bonding Interface of two Ports- add second MLAG Client with dedicated MLAG ID, ...

@fedops @napierge I agree. I like routers that route, and servers that serve

I've often wished I could show #Mikrotik changelogs by component so that I could track a feature's progress. For instance recently a friend asked me about MLAG support in Mikrotik and I said.. ya its been mentioned in recent changelogs a few times. What I didn't realize was that it had also been mentioned in ancient 7.x versions like 7.1.2 so its actually been around a lot longer than I thought. *one weekend coding session later*And the Mikrotik Changelog Tracker was born. It can sort by version number or by date. It can show you changelogs only by component, or you can search for a specific keyword. You can limit your channels to stable, long-term, development and testing. https://mikrotik-changelog-tracker.hextet.net/?q=MLAG#networking #tools

@ij @mikrotik Hardware offloading geht nur 1x pro Switch Chip. Also ein Switch Chip = nur eine Bridge anlegen. Oder mehrere Bridges und selektiv das HW offloading abschalten. Aber eigentlich willst du nur eine Bridge. Man muss es nicht komplizierter als nötig machen.Ich entferne immer die Default Konfiguration. Keine Bridge, keine Ports, gar nichts. Auch keine Überraschungen. So viel verlierst du ja nicht. Die Bridge hält und die Ports, die du sowieso löschen musst...Reset mit System > Reset Konfiguration > No defaults = yes.Bei den Routern ist der "Verlust" bei den "kleinen" Systemen größer. Keine IP, keine Firewall, kein DHCP Server. Aber eben auch keine Überraschungen.
