Hey so I'm trying to setup a NixOS router, and I've set the interface IP address, configured hostapd, made network manager not touch wlp6s0, but the interface is still down. Can't bring it up, also changing the IP has no effect unless I reboot the computer.
<CMCDragonkai>
I previously did it without setting the interface IP address, so it auto configured, and was able to connect to it from another computer, so the hardware should work.
<CMCDragonkai>
Any ideas on how to debug an interface that refuses to come up?

steveeJ: this builds a static qemu-user-arm for nix, and also has a patched copy of nix, so you can convince nix that the host can run arm locally

So after I disabled network manager, I was able to get it working with g hwMode, but not 'a' hwMode, even though my wifi supports 5Ghz, also the auto channel selection doesn't work even if I remove the channel assertions in the hostapd module, so after rebooting several times and twiddling with the settings, it now all works, as long as the hostapd is left on 2.4 Ghz, and networkmanager was disabled, then
<CMCDragonkai>
re-enabled, however I noticed that there's a possibiilty that the network interface can lose its statically configured IP address, and NixOS rebuild doesn't trigger a reset of the interface IP address, you can do this by explicitly removing the IP address using `ip addr del ... dev wlp6s0`

Also I did have networkmanager.unmanaged = [ "wlp6s0" ]; so I'm not entirely sure whether the root cause of the issue is the 5 Ghz settings for hostapd, or some combination of networkmanager interfering
<CMCDragonkai>
You can force a rebuild switch of the static network interfaces, by going into the config, changing the IP to say 2, rebuild switch, then change it back to 1, and then rebuild switch
<CMCDragonkai>
what is weird is that if you have it set to 1, and then use ip addr del... a subsequent rebuild switch won't reset it back to 1
mkoenig has joined #nixos

CMCDragonkai: i think its generating a service, the hash of which depends on the configured ip
<clever>
CMCDragonkai: and only if the hash changes, does it restart the service
<CMCDragonkai>
clever: that's probably it, the service name is called network-addresses-wlp6s0.service
<CMCDragonkai>
clever: I also tried forcing a run like systemctl restart network-addresses-wlp6s0.service, but no effect
<CMCDragonkai>
But I also think that happened because I had another IPv6 address set to it, so the service itself is probably stateful as well and not declarative

CMCDragonkai: i think if you want the wifi to act like a more normal router, you will need to put both the lan wired card, and the wifi card, into a bridge
<clever>
CMCDragonkai: and then set a single static ip on that bridge
<CMCDragonkai>
what are the differences between your proposed idea and using the networking.nat module + hostapd + networking.interfaces + dnsmasq?
<clever>
you would still be using hostapd with my idea, and still need nat to link the br0 and WAN interfaces up
takle has joined #nixos
<clever>
and you would still need a dhcp and dns server on the lan side
<CMCDragonkai>
I'm not currently using a bridge style, instead the NAT module just sets interfaceInterfaces = [ "wlp6s0" ]; and externalInterface = "enp7s0"; and it does the iptables PREROUTING mark, and then POSTROUTING checking for the mark
<clever>
that should work, but the devices on the wifi will never be able to access hard-wired devices, and you currently lack the ability to just hard-wire to the router

what do you mean by hardwire?

I didn't know that would happen. So you're saying having a prerouting rule --set-mark 1 and postrouting rule -m mark --mark 1 -o $externalInterface -j MASQUERADE would prevent clients connected over WiFi to connect to clients connected over ethernet?

Would this be taken care of by the routing table?

is it just me or is latex from unstable missing biber?
<CMCDragonkai>
A bridge would make all clients acquire an IP from the external DHCP wouldn't it?
<clever>
CMCDragonkai: only if you bridge the external interface
<clever>
CMCDragonkai: if you just bridge the internal interfaces, then they will all use the internal dhcp
hiratara has joined #nixos
<clever>
CMCDragonkai: and you can continue to perform NAT between the external IF and the bridge
griff_ has joined #nixos
<CMCDragonkai>
clever: so the solution that gives clients access to each other on the private subnet, and access to the internet via the external interface, is to create a bridge for the internal subnet (and have DHCP listen on that bridge IP), and to also implement NAT from the bridge to the external interface
<clever>
CMCDragonkai: as an example, if you have 3 cards, wlan1, LAN1, and WAN1, you make a bridge br0=wlan1+LAN1, then you configure NAT with internal=br0, and external=WAN1
<clever>
CMCDragonkai: then you run dhcp and dns on br0, and set br0 to 192.168.1.1
<CMCDragonkai>
clever: I see, so basically this is the same as the "natnetwork" mode in Virtualbox as opposed to just "nat" which doesn't allow the VMs to communicate to each other?

clever: It appears that VB doesn't really have a direct analogue, a close one is "natnetwork", but after reading it a bit more, you'd need "host only network" and setup your own NAT from that VB host-only network interface to your external interface
<pie_>
your princess is in another package
<pie_>
also biber isnt listed on the website package search...
<CMCDragonkai>
clever: but the most common that people use is just NAT + Host-Only (the result is that you have 2 IPs in your vms, instead of just 1)

this deletes all non-current generations!
<musicmatze>
maybe you want to keep some of the older generations? If not, just rerun the command :-)
<Criena[m]>
Ok, both commands ran succesfully now, but df -i still shows 99% use.
<Criena[m]>
If only one generations is left now, I wonder where the issue is.
<musicmatze>
I'm not entirely sure why this happens, but I once had the same: running once freed _some_ MB and running again freed a lot more then... after having no inodes left... so sounds good
<musicmatze>
keeping the last 5, maybe 10, should do.
<Criena[m]>
Ok, after removing the first 50 with your suggestion, I tried "... old" again and it finally removed all but the current one.
<Criena[m]>
4GB cleared
<Criena[m]>
71% inodes used. Still quite something, but much more relaxing than 99%.
<musicmatze>
awesome.
<musicmatze>
you have already nixos-collect-garbage ?
<musicmatze>
ah, okay.

If you want a particular change to the build environment for a specific package, it's possible to build just that package with the specific changes.
<simpson>
nixpkgs has special tools to make that possible and easy.
<nhill>
Seems like a major issue really
<simpson>
Well, for example, let's say I want nginx. So I type `pkgs.nginx`.
<nhill>
I've seen things like -O1 vs -O2 cause all sorts of problems

That's not quite what I mean
<simpson>
It's true that it's not free. Each package has to be tested to work with different combinations of features. But it's usually not hard to make optional features in the package become optional features in the Nix expression.
<nhill>
I understand the build environment issues
jmiven has quit [(Quit: WeeChat 1.7)]
<nhill>
But, the compiler is only deterministic for fixed environments if the compiler options are also fixed
<simpson>
They are fixed.
<nhill>
Ok, so all compiler options are fixed throughout the entire component tree?
<simpson>
The Nix expression is fixed, and the inputs are fixed, so the resulting compiler should also be fixed. And by induction, anything that the compiler builds is also fixed.
jmiven has joined #nixos
<nhill>
Ok, so the compiler flags are included in the hash then?
<nhill>
That seems reasonably, but I guess the result is that you can use whatever crazy optimization flags you want but you will likely be forced to compile *everything*
<simpson>
Yes, indirectly, via the Nix expression and builder. There's a fixpoint somehow for gcc, but I'm not sure on the details. I suspect that reading niksnut's thesis would shed light on it.
<nhill>
I'm skimming it right now
<nhill>
So, seems like that also locks most people into a specific compiler
<simpson>
Sure, you have to build whatever Hydra doesn't have in cache, and generally only popular stuff is in cache. It's not *that* big of a deal, generally, unless you customize e.g. Chromium or LibreOffice.
<nhill>
Are you guys gcc or llvm peeps?

simpson: Nothing, you would just not be starting at the bottom. It would be a giant PITA, because you'd be building Nix on top of an unstable foundation

Kind of? I look at a lot of Docker tooling as doing things the Hard Way. But we don't have any anti-Docker bias; we have Docker support in our tools, you can turn Nix expressions into Docker images, etc.
<nhill>
Oh, that's cool
<nhill>
Maybe that's how you would have to build Nix on-top of other systems, recreate an entire system from scratch
<nhill>
Docker style
<nhill>
Then setup a user-transparent transition whenever Nix installed programs are run
<simpson>
Nix is already transparent for stuff of the host machine architecture. It just runs from /nix/store/...
