Definitely stepping up your animated graphics :-) Love it.

man I remember RADIUS

dirty cherry keyboard

I was talking to a cell tech a few years ago, and he was explaining some of the stuff they use. He mentioned "diameter" as the authentication protocol, and I laughed. He gave me a look, like, "... what?" So I said, " 'Diameter'? Like, RADIUS, Diameter...?" The lightbulb went off. "OH.. I never caught that! Huh!"

Another great video!!

I learned about this channel from clabretro. Instantly sub'ed 👍💾

This is one of the best channels on RUclips!

Wow that's brought back memories seeing Solaris again. My first intro to Sun Microsystems was a pair of SPARC 20 servers I set up for email and DNS back in '95. Spent the next 20 years working with a variety of SPARC and x86/x64 systems. Last one I worked on before changing jobs was an M3000. I always likened the sound of the fans on startup to the sound of a Harrier jump jet! The Suns were rock solid kit. My only regret is not bagging one of the SPARC20s when ghey were replaced!

I'm not sure if I missed it or it wasn't covered in the previous episodes. I understand that there are 2 modems used here? One at the PC, and the other one at the terminal server? How do you connect them together for the demonstrations in the video?

One of the best RUclips channels. Thanks guys.

You honestly deserve more than 6k views...

The amount of hours I spent fighting with radius in the late 90s early 2000s i feel your pain. First was converting SCO Unix slip to ppp with compliling merit radius. Every time my company acquired an isp it seamed each used a different radius server. The craziest was one with a microsoft access database as the backend.

Did you try RADIUS in ye ole Cyclades?

Love the reference to clabretro at 1:23! ;D

I know I keep commenting the same thing, but seriously when are we going to see anything regarding ISDN ?

I can't like this enough. The RADIUS GUI you made!! OMG so cool.

12:28 africa : za - yes! We were first on the continent. In a time before Nigeria princes would send you millions.

Wait, did he just say JFIF or GIF89?

Wow! Watching this gave me goosebumps! Thank you everyone who made this possible and for sharing the journey! It made me feel so alive and remember how things were "in the old days" when nerds exchanged ideas and created things.

RADIUS is still critical today for WPA Enterprise, wifi login with credentials.

Cistron was the first radius that I used in the mid to late 90s, and in about 2000/2001 we changed to freeRADIUS, with realms, because by then the Telecoms Company in my country was offering VISP, where they managed the modems/portmasters and just charged you a monthly free and when a user dialed in their main radius would look at the realm and forward the request to your own radius to authenticate, so everyone had an account with username@ispname.tld. I also set up PAM to use RADIUS on our other servers for mail and ftp so the user only needed one user/pass to login to any of their services.

So great to see videos on the history of old tech like this

Holy crap. TACACS is still used today in the enterprise to authenticate to network gear to update software and configs. That and RADIUS is still used today too.

Saw that 15454. Looking forward to that.

RADIUS has been on my todo list too for WPA3-EAP and 802.1X

Man, I only touched Microsoft Active Directory, and RADIUS on my Cisco IOS homelab. This is very enlightening.

Michnet was my gateway to the Internet! Used to login to a System V system and then telnet over to the Grand Rapids Freenet and Detroit Freenet. I started browsing the web using Lynx and Pine for email. Simpler times for sure...

That's definitely a worldly choice of User-Password there.

so they invent internet tracking... that doesn't sound great...

Darnit, I wished that I wasn't on the other side of the world.

Crazy how far radius has come, to go from being one of the most essential parts of an isp to being used at almost every hotel/venue with public wifi

Thank you! I just bought a Portmaster 3 from ebay and have it working with local users, but haven't yet figured out the RADIUS server from Livingston. This video will definitely come in handy! There's a WinNT version of Livingston/Lucent RADIUS too but idk if it's worth setting up since it's beta software (although y'all probably know that since I pulled the Livingston files I needed from your website lol).

We're making a heavy use of both FreeRADIUS and TACACS (only for some specific use-cases) at our datacenter. Funny how simple protocols from 80/90s are still with us and better than ever,

It'd be fun to see you pair up with @ThisMuseumIsNotObsolete to get the ISP running over his reall telephone exchange he has running in his museum

Some trivia, there's an evolution of RADIUS protocol and it's called... DIAMETER. It's mostly supported on 3GPP gear (GGSN, real-time charging) AFAIK and not as well supported in common network stuff as RADIUS.

One thing that immediately caught my attention during the compilation of the orignal radiusd, was the "incompatible implicit declaration" errors. This is most likely part of the issue that causes password decryption to fail. This should be relatively easy to fix by adding the approriate header files to be included. With conf.h being present, maybe this is also where one would usually include headers (and change the options vs. adding them to the Makefile). Or maybe the version of C compiler this project originally used had some standard includes set that provided the "missing" functions.

That day a full /tmp caused an empty file tonbe semt to all radius servers... Nome of our customers could log in. Fun times working on the helpdesk 😂

Ah yes, the "designed by committee" quagmire. Instead of using an existing good, well thought out system - that would give someone "an advantage" - they have to design something inferior to equally inconvenience everyone. We'll give everyone a say, and staple everyone's ideas together. (i.e. the submarine in the Lego Movie... a dozen people all trying to do something different.) Having used TACACS+, RADIUS, and several other systems, TACACS+ is not perfect, but RADIUS is _significantly_ less perfect. In modern terms, I can cut it some slack... security wasn't really a big concern in that era, things like SSL/TLS hadn't been invented yet. (not that AAA traffic should be going across a remotely untrusted network.) Despite "open" and "universal", _every_ vendor did stupid proprietary shit with it. (USR worst of all! USR's vendor-specific-attributes are not RADIUS attributes, they're binary blobs.)

I have been using Free RADIUS server since 2010 for user access for my Wi-Fi Network started running on a Windows XP machine but now running on a Synology disk station using LDAP database

I use to work with freeRADUIS doing AAA on cell connections and fibre. This took me back.

Great Video, can't wait till you start on the 56k era.

Great video as always!, cant wait for the digital saga!

Aww yeah! Waited for this

It's really great to see the ISP grow. Great videos, guys

Woo! Love the dial-up content!

Nice work. Great to see you using KDE, too.

Are you going to pack this into some vm image? Like QEMU

I am surprised they ran it their server until 2023 as chinese or russian idiots would have been constantly trying to attack their server.

Great to know the last copy came from my country. Good luck with your projects, I love your channel!

I don't remember Archie. I remember guessing at newsgroup subsets and printing massive lists of servers.
