Starting ssh service

Starting ssh service

[Dick Middleton]

Hello,

	Just started playing with Guix and am trying to get ssh to start as a service.

My system is configured using the standard desktop example config.scm given
with the installation.

I'm trying to add the relevant bits from the simple example in reference guide
  "7.2.1 Using the Configuration System".

i.e I've added:

(use-service-modules networking ssh)
...
(services (cons* (lsh-service) %base-services))

guix reconfigure complains with this error: ssh-daemon requires 'networking'
which is undefined.

Do I have to install something (why is it not already installed?) or am I
doing something wrong?

Thanks

Dick

The desktop example use '%desktop-services' (in gnu/services/desktop.scm).
It contain services like dbus, slim, and wicd, etc.

wicd-service is provide the 'networking'.

You can use '%desktop-services' (or add 'wicd-service' or others.
see the 7.2.7.2 Networking Services section of the manual).

Hope it helps!

Placing lsh-service in %desktop-services allows guix to complete reconfigure
but it doesn't start the service.

If instead I order assigning %base-services and %desktop-services so
%base-services comes first (that was perhaps my mistake) then the build
proceeds.  However now lshd starts at boot time but the desktop GUI doesn't.

How should I configure a server with a GUI?

Do you mean that when you use:

  (services (cons* (lsh-service #:port-number 22
                                #:daemonic? #t
                                #:root-login? #t)
                   %base-services))

the server is started, but with:

  (services (cons*
             (xfce-desktop-service)
             (lsh-service #:port-number 22
                          #:daemonic? #t
                          #:root-login? #t)
             %desktop-services))

it is not, right?

If so, I have no idea how this could happen.

'services' (and any other field) should be specified only once.
Apparently the first one (with %base-services) has a preference, so ssh
server is started and desktop services are not.

This sounds similar to issues I ran into with a headless server running
GuixSD a month or so ago (have since switched to Guix/Debian).

I ended up with lsh-service providing sshd (the ssh server) and openssh
providing ssh (the ssh client).

The config is split with sshd in the system config and ssh in the
per-user config.

There may be a more sane approach, but this did work and, FWIW, I have
attached the actual configs.

Ah, but I think you do ...

That explains a lot.

I'll try again.  Many thanks
