Peter Hoeg c4cba0e51f ssh module: ignore exit code when socket activated
sshd will at times fail when exiting. When socket activated, this will
leave a number of sshd@ service instances in the failed state, so we
simply ignore the error code if we are running socket activated.

Recommended by upstream:

Fixes: #3279

Eelco Dolstra 401782cb67 Revert "openssh: 6.9p1 -> 7.0p1"
This reverts commit a8eb2a6a81. OpenSSH
7.0 is causing too many interoperability problems so soon before the
15.08 release.

For instance, it causes NixOps EC2 initial deployments to fail with
"REMOTE HOST IDENTIFICATION HAS CHANGED". This is because the client
knows the server's ssh-dss host key, but this key is no longer
accepted by default. Setting "HostKeyAlgorithms" to "+ssh-dss" does
not work because it causes ssh-dss to be ordered after
"ecdsa-sha2-nistp521", which the server also offers. (Normally, ssh
prioritizes host key algorithms for which the client has a known host
key, but not if you set HostKeyAlgorithms.)

Peter Simons 86d299bc6e nixos: add config.services.openssh.moduliFile option so that users can replace the default file from OpenSSH
The man page for ssh-keygen(1) has a section "MODULI GENERATION" that describes
how to generate your own moduli file. The following script might also be helpful:

 | #! /usr/bin/env bash
 |
 | moduliFiles=()
 |
 | generateModuli()
 | {
 |   ssh-keygen -G "moduli-$1.candidates" -b "$1"
 |   ssh-keygen -T "moduli-$1" -f "moduli-$1.candidates"
 |   rm "moduli-$1.candidates"
 | }
 |
 | for (( i=0 ; i <= 16 ; ++i )); do
 |   let bitSize="2048 + i * 128"
 |   generateModuli "$bitSize" &
 |   moduliFiles+=( "moduli-$bitSize" )
 | done
 | wait
 |
 | echo >moduli "# Time Type Tests Tries Size Generator Modulus"
 | cat >>moduli "${moduliFiles[@]}"
 | rm "${moduliFiles[@]}"

Note that generating moduli takes a long time, i.e. several hours on a fast
machine!

This patch resolves https://github.com/NixOS/nixpkgs/pull/5870.

Eelco Dolstra c0f70b4694 Remove fixed uids for nscd, sshd
These services don't create files on disk, let alone on a network
filesystem, so they don't really need a fixed uid. And this also gets
rid of a warning coming from <= 14.12 systems.

Vladimír Čunát 72d2d59cd4 /etc/ssh/ssh_known_hosts: refactor and fix #5612

Functionally it should create the same content as before,
only adding the newlines.

Revert "nixos/sshd: drop mode from auth keys file".
This reverts commit a3331eb87b.

See https://github.com/NixOS/nixpkgs/issues/2559#issuecomment-47313334
for a description why this is not a good idea.

I guess it's better to implement a sane way to remove all files in
authorized_keys.d, especially because it is also backwards-compatible.

Reopens #2559.

Eelco Dolstra 03d9e5cda0 sshd: Add support for socket activation
By enabling ‘services.openssh.startWhenNeeded’, sshd is started
on-demand by systemd using socket activation. This is particularly
useful if you have a zillion containers and don't want to have sshd
running permanently. Note that socket activation is not noticeable
slower, contrary to what the manpage for ‘sshd -i’ says, so we might
want to make this the default one day.

Eelco Dolstra 29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

Eelco Dolstra ae74b0ae58 sshd: Remove the usePAM option
Sshd *must* use PAM because we depend on it for proper session

from sshd's PAM service.

That is, you can say

instead of

  security.pam.services = [ { name = "sshd"; options... } ];
