This conflicts with the existing reference NTP daemon, so we're using
services.ntp.enable = mkForce false here to make sure both services
aren't enabled in par.
I was already trying to merge the module with services.ntp, but it would
have been quite a mess with a bunch of conditions on the package name.
They both have a bit in common if it comes to the configuration files,
but differ in handling of the state dir (for example, OpenNTPd doesn't
allow it to be owned by anything other than root).

* The module now has systemd config
* Add resolveLocalQueries option which sets up it as a dns server for
local host (including reasonable setup of resolvconf)
* Add "dnsmasq" user for running daemon
* Enabled dbus and dnssec support for the package

Should bring most of the examples into a better consistency regarding
syntactic representation in the manual.
Thanks to @devhell for reporting.

Additionally, remove the automatic initialization of the ipv6 forwarding
sysctl as this should be handled by the end user. This really should not
be an issue as most people running radvd are likely forwarding ipv6
packets.
Apart from s/types.string/types.str/ (or types.lines where appropriate):
* port is changed from string to int.
* extraFlags is changed from types.string (with unfortunate merge
semantics) into a list of strings. A list of strings merge better:
one space is added between elements.
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.

This fixes several problems in the dhcpcd service:
* A segfault during startup, due to a race with udev (dhcpcd would get
an ADD event from udev, causing it to re-add an interface that it
already had, leading to a segfault later on).
* A hang/segfault processing "dhcpcd rebind" (which NixOS calls after
waking up from suspend).
Also, add "lo" to the list of ignored interfaces. It usually ignores
"lo", but apparently not when it gets an ADD event from udev.
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.
This causes OpenVPN services to reach the "active" state when the VPN
connection is up (i.e., after OpenVPN prints "Initialization Sequence
Completed"). This allows units to be ordered correctly after openvpn-*
units, and makes systemctl present a password prompt:
$ start openvpn-foo
Enter Private Key Password: *************
(I first tried to implement this by calling "systemd-notify --ready"
from the "up" script, but systemd-notify is not reliable.)
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.
This prevents errors like "Another app is currently holding the
xtables lock" if the firewall and NAT services are starting in
parallel. (Longer term, we should probably move to a single service
for managing the iptables rules.)
- Make dhcp work, use dhcpcd without udev in container
- Make login shell work, patch getty to not wait for /dev/tty0
- Make ssh work, sshd/pam do not start session
For example, the following sets up a container named ‘foo’. The
container will have a single network interface eth0, with IP address
10.231.136.2. The host will have an interface c-foo with IP address
10.231.136.1.
systemd.containers.foo =
{ privateNetwork = true;
hostAddress = "10.231.136.1";
localAddress = "10.231.136.2";
config =
{ services.openssh.enable = true; };
};
With ‘privateNetwork = true’, the container has the CAP_NET_ADMIN
capability, allowing it to do arbitrary network configuration, such as
setting up firewall rules. This is secure because it cannot touch the
interfaces of the host.
The helper program ‘run-in-netns’ is needed at the moment because ‘ip
netns exec’ doesn't quite do the right thing (it remounts /sys without
bind-mounting the original /sys/fs/cgroups).
This is useful for packages like mosh, which use a wide UDP port range
by default for incoming connections.

There are two fixes in this commit.
Firstly, I am creating proper symlinks for the Alias= definitions in the
.service files. This achieves the same result as `systemctl enable`, and
I think is preferred over `mv`.
Secondly, `networkmanager-init` now wants `NetworkManager.service`,
along with `ModemManager.service`. ModemManager does not depend on
NetworkManager (according to `systemctl list-dependencies ModemManager`),
thus NetworkManager never got started on boot.
This patch adds support for the creations of new bond devices, aggregate
pipes of physical devices for extra throughput or failover.
Additionally, add better correction at the startup of a bridge
of vlan interface (delete old, stale interfaces).
If you want minidla to accept connections from the rest of the world, please
add
networking.firewall.allowedTCPPorts = [ 8200 ];
networking.firewall.allowedUDPPorts = [ 1900 ];
to /etc/nixos/configuration.nix.
See <http://lists.science.uu.nl/pipermail/nix-dev/2013-November/011997.html>
for the discussion that lead to this.
ntopng is a high-speed web-based traffic analysis and flow collection
tool. Enable it by adding this to configuration.nix:
services.ntopng.enable = true;
Open a browser at http://localhost:3000 and login with the default
username/password: admin/admin.
- It now uses JavaScript for configuration (only),
so I had to "convert" config for NetworkManager.
- I tested suspend/restart/(un)mount on KDE/Xfce,
Phreedom tested NetworkManager config conversion.
Sshd *must* use PAM because we depend on it for proper session
management. The original goal of this option (disabling password
logins) can also be implemented by removing pam_auth authentication
from sshd's PAM service.
That is, you can say
security.pam.services.sshd = { options... };
instead of
security.pam.services = [ { name = "sshd"; options... } ];
making it easier to override PAM settings from other modules.
vsftpd improvements:
- intorduce one declarative list of options
- make docummentation strings more understandable and add missing options
such as SSL/TLS support
- Use environment.etc."vsftpd".text because I can't think about any
reason why a shell script should be used.
That code was written in 2009.
