I use Discord now since most of my friends are on it, but I've always been a fan of Mumble (and murmur server) since it's high quality software and open source. I also made https://guildbit.com years ago for gamers that want to just quickly spin up a temporary server with their friends. I still operate it today since there's still a few users out there. I think it would be cool if someone were to create an open sourc…

I think mattermost is working on a couple plugin.

I really appreciate Mumble's dedication to lowering latency. Latency is a silent killer of conversation quality. When it's relatively small, you don't notice it's there, but it makes conversations more stilted because everyone's responses are just a bit less immediate. You chalk it up to the person or situation, rather than the software. I'm not seeing anyone make significant attempts to solve or reduce this problem.…

> To my ears, 2010-era Skype had lower latency than any of the modern VOIP systems in use today (including Skype). Yeah! What happened?

P2P vs using central servers.

This is all thanks to NAT. Skype had very creative functionality to pierce through NAT.

Apparently patents in this form need to be abolished ASAP. Human society can't afford anything like this standing in the way of widespread usage of such well known and well available technologies. Please, let's all go and short that patent troll.

IMO, all patents need to be abolished ASAP. They're a bad idea to begin with, and this case is just particularly ridiculous. Don't hate the player, hate the game.

Maybe for technology. The patents are still somewhat useful outside IMO. The whole idea about patent was that you could enjoy temporary monopoly in exchange of disclosing information about your invention.

For example thanks to patents we have generic version of medication, instead of them being trade secrets. Yes I know there are other things like drug approval that requires disclosing this information but that works together with patents.

It looks like voice packets are intended to be OCB2 (CryptState.cpp, cryptstate go package in Grumble). I haven't read the code through to figure out how to mount it (and it looks slightly funky), but if it does what it says on the tin there's a trivial, one-encryption-oracle-message forgery attack for that. Also: I don't think that means you shouldn't use Mumble. I just think someone should see if they can exploit t…

Is it the last step of the encrypt function which would need an additional XOR operation added (XEX va XE for the encryption of the tag) to mitigate this attack? [1]

  S3(delta);
  XOR(tmp, delta, checksum);
  AESencrypt(tmp, tag, &encrypt_key);

We live and die by Mumble in Eve Online. The hierarchical chat room setup is essential for large fleets.

Also important is the "priority speaker" function which let's a certain group, or channel automatically be louder than local chatter. So you can have a small subgroup actively coordinating and the fleet commander can give orders which don't get lost.

Mumble also has much better security/permissions. Last time I looked it was pretty easy to dump the list of active users on a discord "chat". That means you could always know if someone was forming for an attack etc.

Any idea why? Sounds stupid, considering latency losses and increased server costs.

Surprised no one mentioned the documented reason: the VirnetX parent lawsuits, which were also why Apple had to stop using P2P in FaceTime. https://arstechnica.com/gadgets/2013/04/after-200m-patent-se...

Can anyone explain to me why so many companies invest in VirnetX? it's pure evil. https://www.nasdaq.com/symbol/vhc/institutional-holdings

It's unfortunate because Mumble is great, secure free software with interesting features. I used to be a linux distro package manager for Mumble. Once my friends discovered discord no one wanted to join my mumble anymore. I think the biggest problem was setting the damn thing up on the client side. Murmur server is free though. It even runs great off of a home internet connection if you have the technical know-how to…

Yeah, I ran a Mumble server for my group of friends for years. Basically zero maintainance beyond ensuring the package was up to date. The client was fast but as you said, setting it up was less friendly than Discord. Same thing happened, everyone moved to Discord.

Is there a guide or at least a pointer to what the server binary is? I haven't been able to find a headless one on a cursory search.

It's called murmur (mentioned elsewhere in the thread)

Mumble has been the highest-quality group voice chat system for many years now. It's unfortunate server is such a pain in the ass to get running properly. I'd rather pay for a commercial Mumble server than go through that troubleshooting nightmare again.
