The gateway has been replaced with a desktop computer sitting on its
side in the rack on top of the multi-hd storage server. Note that this
is super janky since the two PCI network cards can't be mounted
properly in the somewhat-smaller-than-standard case.
We added two network cards and were planning to use the built-in card
as well, but currently the built-in card is not used and the private
network is down. There are two reasons:
* The switch used for the private network had one of its fans die and
I turned it off until we can replace the fan so it won't overheat
* The built-in network card appears to need firmware which I'm not
going to bother with until the fan on the private network switch is
replaced
Also, we might get a new server rather than using this old desktop machine.
The new computer is using the old harddrive. I changed the following
files due to the different names of the network interfaces:
/etc/network/interfaces
/etc/default/isc-dhcp-server
/etc/iptables/rules.v4
/etc/iptables/rules.v6
You can find backups of the files from before my changes at the same
paths with .old added (for the parent dir for /etc/iptables)

Dear sudo-sys,
I set up a Mumble server for Sudo Room. It is running uMurmur on Sudo Room's saros machine, and is reachable at address room.sudorom.org.
Relevant files:
- /usr/local/etc/umurmur.conf - Server config file
- /usr/local/src/umurmur - Server source directory
- /usr/local/etc/systemd/system/umurmur.service - Systemd service file
- /etc/iptables/rules.v[46] - Firewalls updated to allow incoming connections on port 64738
Relevant commands:
- systemctl status umurmur - Check the server status
- sudo systemctl restart umurmur - Restart the server
- sudo journalctl -u umurmur -f - Follow the server log
uMurmur is a lightweight Mumble server implementation. I first learned of it from browsing OpenWRT package repos. If you check e.g. htop, you can see it uses very little RAM or CPU. Bandwidth usage should also be low, and is limited by some config settings.
More info on this Wiki page:
https://sudoroom.org/wiki/Mumble
I also published a private message about it on Secure Scuttlebutt (SSB): %6wUU2x+wrO4vJbhebX+p9iYlNuS8EnNlPyGT5o4ogaU=.sha256
I hope this can be useful for Sudo Room people and groups wanting to have high-quality low-latency voice chats, or who like Mumble and could use a server that is more geographically close to them and not in a corporate cloud. Does sudo-sys have any feedback before I share it to sudo-discuss?
Regards,
Charles (cel)

Hello Folks,
First and foremost please excuse me if the questions below have been
answered before.
1. Why is *NoiseBridge using Slack (Corporate),* isn't privacy a concern?
2. Why is tomorrow's (2020/04/05) *NoiseBridge CryptoParty* being held via
*Zoom*, when the party itself is about *privacy*?
3. Why not use their open source alternatives?
Confused.
