jdev - 2019-08-19

Kindly ignore this message.

No!

Hm it would be nice if this group chat had a proper name. Something like "Jabber/XMPP Development". I think the name/title is not set yet.

wurstsalat: the proper name of this room _is_ jdev, so I set that as its title. The description is "Jabber/XMPP Development".

It might be that your client shows this suboptimally.

alright! no it shows "jdev" corretly then

I wish conversations displayed the topic at the top instead :(

I named my bookmark for this room "XMPP Development"

Zash, good idea, Gajim had some improvements for name displaying lately :)

Hi, I'm new to servers and networking. I want to build an xmpp server(I'll rent the server). It's for a chat application I want build(learning project )

Any suggestion ? Please be as basic as possible as I'm new

Get a Debian VM, install Prosody, tweak the config and poke some DNS, ???, PROFIT!

Zash Thanks. I have a linux VM installed on my mac. I installed prosody on it I tested it with prosody's client IM app and it works(my domain is localhost). I'm using a bridged network connection. Connecting to the VM from the Mac (host) is the challenge

bent3n - Openfire is pretty easy to setup on any computer

Prosody is a server, not a client.

and geared towards easy entry

I don't know if I was doing anything wrong that's why I decided to rent a server and then learn

guus.der.kinderen I installed openfire on the linux guest. I can only access the admin webpage from the host( my MAC)

bent3n exactly what is your goal here? If it's just to experiment, I'd be perfectly happy to host a service for you for a couple of days.

that'd save you from the troubles of setting one up yourself.

I'm learning from a textbook. and the HTTP connection manager in the textbook is no longer up. So I'll have to create my own if I want to learn

if you'd try to learn how to setup a server, then you'd have to set it up yourself, obviously :

yeah. Unless bridging between my host and my guest works(which hasn't for me right now) that's why I'm leaning more towards renting a server

let me set one up for you, so that you can at least experiment for a couple of days

if you want to rent that later, we can discuss it.

woudl that work for you?

That would more than work

I don't know about you all but I just run `./prosody` locally on my workstation. Renting a whole machine seems like a bit overkill.

thanks guus.der.kinderen

no problem. pick any subdomain (as in the 'something' in "something.goodbytes.im") please

guus.der.kinderen Zash Here's the app I wanted to test :

let Hello ={ connection: null, start_time: null, log: function(msg){ $("#log").append("<p>"+ msg +"</p>"); }, send_ping: function(to){ let ping = $iq({ to: to, type:"get", id:"ping1"}).c("ping", {xmlns:"urn:xmpp:ping"}); Hello.log("Sending ping to:"+to+"."); Hello.start_time = (new Date()).getTime(); Hello.connection.send(ping); }, handle_pong: function(iq){ let elapsed =(new Date()).getTime() - Hello.start_time; Hello.log("Received pong from server in : "+ elapsed+" ms"); Hello.connection.disconnect(); return false; } }; $(document).ready(function(){ $("#login_dialog").dialog({ autoOpen: true, draggable: false, modal: true, title:"Connect to XMPP", buttons:{ "Connect": function(){ $(document).trigger("connect",{ jid: $("#jid").val(), password: $("#password").val() }); $("#password").val(""); $(this).dialog('close'); } } }); }); $(document).bind('connect', function(ev, data){ let conn = new Strophe.Connection("http://bosh.metajack.im:5280/xmpp-httpbind"); console.log(conn); conn.connect(data.jid, data.password, function(status){ if (status === Strophe.Status.CONNECTED){ $(document).trigger('connected'); }else if (status === Strophe.Status.DISCONNECTED){ $(document).trigger('disconnected'); } }); Hello.connection = conn; }); $(document).bind('connected', function(){ // inform the user Hello.log("Connection established"); Hello.connection.addHandler(Hello.handle_pong, null, "iq", null, "ping1"); let domain = Strophe.getDomainFromJid(Hello.connection.jid); Hello.send_ping(domain); }); $(document).bind('disconnected', function(){ Hello.log("Connection terminated..."); //remove the connection object Hello.connection = null; });\

woah, please don't copy that much code here 🙂

some of us are on mobile phones 🙂

guus.der.kinderen bent3n would be ok for the subdomain

Déjà vu https://logs.xmpp.org/jdev/2019-08-09?p=h#2019-08-09-ce5c5bf5f9431f5b

Zash Yes, I tried what JC suggested by installing prosody on my guest (Linux on the VM on my MAC)

guus.der.kinderen Sorry I did not know that

There isn't much stuff out there for a beginner(let alone recent material). Like I said. I'm a beginner with 0 experience with networking

bent3n, email me at guus@goodbytes.nl so that we can exchange credentials etc

note that I'm not planning to provide development support with regards to your textbook code 🙂

guus.der.kinderen just emailed you

received it, tx. I'll forward you instructions shortly

it takes about 10 minutes for the provisioning to happen.

Thanks

no problem with code support. I need a connection manager that works. the book I'm using is about 10 years old. The only trustworthy resource for beginners I could find

Yeah, that's an issue. We (the XMPP Standards Foundation) could use more resources for easy entry.

Hot damn, published in 2010? Time flies.

hahahaha. It's Jack Moffit's book

I know, I have it

The Book is even older.

2008 or so?

Although as it's not code-sample based primarily, it's pleasing how often it's still relevant when I point the team to it.

Kev: Time for a remake?

I think it's not worth it until we've solved the archive+routing2 stuff.

At that point, maybe.

bent3n check your mail

note that DNS propagation might require some time to get to every corner of the earth - but it's usually pretty fast.

just seen it. Thanks guus.der.kinderen !

Oh, I should upgrade that webclient that ships with it. The latest version has interesting debugging options, which will probably help you in your own efforts.

I'll try upgrading later.

thank you so much ! guus.der.kinderen

I just upgraded it (still had the console open 😛 )

try hard-refreshing the inVerse URL if you had already opened it. It should have changed from version 4.2.0 to 5.0.1.

I've now enabled debug mode on that client. If you open the development console of your browser (typically: F12), you'll see a bunch of useful information.

guus.der.kinderen I got this error when I entered my credentials into the page that loaded from the inverse URL

2019-08-19T14:32:39.174Z WARNING: Message Archive Management (XEP-0313) not supported by this server

known issue - ignore it - it simply works.

ok cool !

https://github.com/conversejs/converse.js/issues/1676

guus.der.kinderen Kev Zash So next is to configure the server to do something right? I ask I switched out the connection manager to the one Guus provided and it still shows connection terminated -- I was expecting it to connect at least

I'm new to networking

the XMPP server can be used to connect your XMPP client to, and to use that to send back and forth messages.

the connection manager (BOSH) is one way of connecting to the server (it's basically an HTTP wrapper for XMPP traffic)

I've provided you with an account. You should be able to use that to authenticate against the server, and start sending messages and whatnot.

Most XMPP servers these days have a BOSH connection manager built into the server itself, so it's not a proxy anymore and might behave differently to a standalone BOSH proxy

Zash So does that mean the code I provided above will have to be edited in some way ? Kev These are the files I downloaded so I could use strophe for the example in the book (Hello app on chapter 3)

1. checkplayer.js 2. flensed.js 3. flXHR.js 4. flXHR.swf 5. flXHR.vbs 6. strophe.flxhr.js 7. swfobject.js 8. strophe.js 9. updateplayer.swf

Am I missing any ? can you please point me in the right direction so I can download the files necessary/relevant today so I can complete that example ?

(i'm off to feed the offspring)

hahaha the offspring

Swf ?

If your book wants you to use flash in 2019 burn it

Haha .vbs too even better

bent3n: I know nothing much about Jack's book, and I don't do JS-based XMPP. Pinging me won't help here.

Yeah, this stuff is from before CORS was widespread

yea I suspect you'd be better off burning that book and going with something from this decade

otherwise you are going to struggle a lot with implementing it, then be rewarded by it not working in any modern browser

I would suggest not to *burn* the book, but putting it aside is probably wise.

details details... :)

travis: The problem is that there's no book from this decade.

Depending on whether 2010 counts as this decade or the previous one.

probably true

Off got I plane to catch. I'll land at 3pm ET

Zash: Well, that's only a problem if the book was written as a guide for a codebase.

I think (obviously biased) TDG has aged relatively well, but obviously Jack's book on strophe is going to age badly because the web has changed in 10 years.

Kev: Sure, XMPP basics probably haven't changed all that much. Higher level things have moved a bit tho. Were Carbons and MAM around back then for example?

I don't recall. I think 289's in there but not 313, but wouldn't swear to it.

But sure, thing's have changed. The question is whether what's there becomes wrong, or just incomplete.

Also the sleekxmpp book is still here to haunt us for some time. I wouldn't even recommend slixmpp nowadays, I'm looking forward to aioxmpp in Python ✏

"looking forward to"?

pep.: You mean TDG? Most of the book doen't cover sleek, there's just a few examples at the back.

Hmm, badly said

I don't know the book, Kev. I'm just heard there was one on sleekxmpp.

Not AFAIK.

But TDG has some SleekXMPP examples at the back.

I'm not sure if Jack's book has aged that badly. Strophejs just works and I don't think it is affected as much as other web technologies.

.swf was mentioned above

if it has you copying around .swf and .vbs files that's a bad sign

I'd summarise most new development around frameworks for presentational code, single page apps, WebRTC. So stuff using strophejs might have changed dramatically.

Which reminds me ikDisplay should have a complete overhaul of its UI bits.

ralphm, was ikDisplay pubsub based?

Is. Yes.

E.g. a feed on XMPP: https://display.ik.nu/xmpp

Still has the FOSDEM banner on it 🤣

😀

It used to be smooth, but browsers have changed and UI should be redone to use modern transitions features.

ralphm Zash moparisthebest Kev MattJ So where would you point a beginner ? For learning resources and the necessary files for strophe or any other JS xmpp library?

I'm open to new libraries provided there's support and a community? currently checking what webRTC is

JC told me about converse a couple of weeks ago

I would guess converse.js would be the way to go
