[Nix-dev] HP Network Printer (CUPS + HPLIP)

2016-03-14 Thread Sergiu Ivanov 

Hello,

I'm trying to set up CUPS to use a HP LaserJet Enterprise 600 M602 [0]
on my NixOS system.  Here is the relevant snippet of my
configuration.nix (taken from the wiki [1]):

  services.printing = {
enable = true;
drivers = [ pkgs.hplip ];
  };

hp-setup does not detect the printer and says "No devices found on this
bus: net".

In Web administration interface for CUPS, I click "Add Printer" then I
select HP Printer (HPLIP) and I specify socket://192.168.0.11 as
connection string (I can ping this address). Then, when I get to the
screen giving the list of models, I *cannot* see the model of my
printer, even though the directory

  $(nix-build '' --no-out-link -A hplip)/share/ppd/HP/

contains a file hp-laserjet_600_m601_m602_m603-ps.ppd.gz .

I gunzip this file in a temporary folder and load it explicitly via the
CUPS Web interface.  Then, when I tell the Web interface to print a test
page, the job fails with the message 'stopped "Filter failed"'.

How would you normally set up HPLIP to work correctly with CUPS?

(I think I used to install foomatic on Arch Linux, but I'm not sure any
more.)

Re: [Nix-dev] Amazon EC2 rebuild switch causes kernel panic

2016-03-14 Thread Roger Qiu 
What's happening is the transition from stage 1 booting to stage 2 booting
is failing. The error reported is that the init script that is be executed
once switch_root is executed is non existent. Which could mean your initrd
is corrupted or the build failed for some reason or some other config
problem at stage 1.

If you could inspect the initrd to check if the init script is there...

[Nix-dev] Amazon EC2 rebuild switch causes kernel panic

2016-03-14 Thread Paul Cooley 
I brought up an AWS instance using nixos-15.09.git.87b377dM-x86_64-pv-ebs . 
After modifying /etc/nixos/configuration.nix to use the "amazon-init.nix" 
rather than "amazon-image.nix" and performing a 'nixos-rebuild switch' command, 
the instance reports the following error.

That should be:

sudo nix-store --import < example.closure

(note the '<').

Worked perfectly. Where can I add documentation?

You can skip signature checking by using root:

sudo nix-copy-closure --import example.closure

I found this on the Nix issue tracker somewhere. It might not be
documented behaviour.

You can define any host / port matching through the configuration file
"~/.ssh/config" for any program using SSH.

Something like

""
Host [youHost]
port 1

"""

should do the trick

Can you change the port by adding an entry to .ssh/config? That should
allow you to set the port, and I believe nix-copy-closure just calls SSH.
You might need to use /etc/sshd/config, as I'm not sure what user it's
actually making the ssh connection as.

[Nix-dev] How to use binaries from other hosts?

2016-03-14 Thread Matthias Beyer 
Hi,

I'm on nixos unstable. As racket does not build and my thinkpad takes hours to
build it, I got myself a debian VM in my university cloud and compiled racket
there.

How can I retrieve the closure from there?

I tried _everything_. I cannot nix-copy-closure, as this one does not allow me
to set the SSH port (which isn't 22 but something above 1).

I tried to nix-store --export, copy via SCP and then nix-store --import, but it
fails as the closure is not signed...

Can someone please help me with this?

I normally install racket with a nix-shell for my blog environment. I guess I
should make this shell env persistent to be save of GC, though I cannot find
documentation on how to _remove_ a persistent shell env... and I want to know
how to remove it, before making it permanent.
