XMPP Service Operators - 2023-05-12

Hello everybody

If i want to add account with onion server

How to do it

sedula: Can you elaborate on what you're trying to achieve?

I try to use accounts with other servers not like @conversations.im

Because i cant contact some of my friends

They have like example

Sgdnfjfifnckfjfnsjxjdjfkdnfgau@onion.nl

And i cant write to them

They cant write to me

the server needs to be setup to federate with it via eg. mod_onions for that to work

Can you explain me how to set it up

sedula: Only available for Prosody. Check the admin manual.

Where to check

For some friends somebody can online to configure it

What?

> Sgdnfjfifnckfjfnsjxjdjfkdnfgau@onion.nl This isn't an onion address but a regular domain ↺

How to make acount like this

Fteheidhdxjbfksbdj@onion.nl or something like this

Because from @conversations.im

We cant contact each other

I think you have the server wrong because http://onion.nl redirects to something different and doesn't appear at first glance to actually be a server?

there are like onion.proxy.tld proxies that will make an actual onion available over clearnet

which probably wouldn't actually handle xmpp traffic well

I haven't seen those for XMPP, it'd require terrible JID rewriting hacks

they may be trying to use one is what I mean

ah maybe, but that site doesn't seem to be that either

they may not be mentioning the actual domain and there are a handful similar onion.tld that do exist

Deh

hey PSA: there's a local privilege escalation (both user -> root and container -> host) in Linux (CVE-2023-32233) which hasn't been patched in either debian or ubuntu at this time. You may want to deploy (partial) workarounds (`sysctl -w kernel.unprivileged_userns_clone=0` and persist that in /etc/sysctl*). See also https://www.openwall.com/lists/oss-security/2023/05/08/4 ✏

fedora has 6.2.15 in testing, to install it: sudo dnf update --refresh --enablerepo=*updates-testing kernel*

jonas’, thanks. I wasn't aware of the workaround... do you know if it has any negative impact?

yes

chromium doesn't work anymore

:D

and it doesn't help you for containers running as root

So luckily no negative impact for my use of docker (jitsi-meet on my vps). 😇

it won't help in that case either afaiu
