In the previous version multiple default values would generate an
invalid babeld config file since all options would be concatenated
without any separator.
* Safer defaults for immutable znc config
I just lost all the options I configured in ZNC, because the mutable config was overwritten.
I accept any suggestions on the way to implement this, but overwriting a mutable config by default seems weird. If we want to do this, we should ensure that ZNC does not allow to edit the config via the webmin when cfg.mutable is false.
* Do not backup old config files.
There seems to be little need for backups if mutable becomes a voluntary opt-out.
* fixup
We now wait for dhcpcd to acquire a lease but dhcpcd is restarted on
system activation. As wpa_supplicant is stopped while dhcpcd is
restarting a significant delay is introduced on systems with wireless
network connections only. This changes the wpa_supplicant service to
also be restarted together with dhcpcd in case both services were
changed.
The current version is broken:
- there's no `openFirewall` attribute directly in the `cfg` set
- the `port` option is an attribute of the `confOptions` set
I used the proper attribute for the firewall port and moved the `openFirewall`
option directly up to the `services.znc` set, as it's rather a general option
for the whole service than a znc-specific option (which are located inside the
`confOptions` set).
Sometimes (especially in the default route case) it is required to NOT
add routes for all allowed IP ranges. One might run it's own custom
routing on-top of wireguard and only use the wireguard addresses to
exchange prefixes with the remote host.
This has been broken nearly all the time due to the patches needed to
iproute2 not being compatible with the newer versions we have been
shipping. As long as Ubuntu does not manage to upstream these changes
so they are maintained with iproute2 and we don't have a maintainer
updating these patches to new iproute2 versions it is not feasible to
have this available.
This reverts commit 670b4e29adc16e0a29aa5b4c126703dcca56aeb6. The change
added in this commit was controversial when it was originally suggested
in https://github.com/NixOS/nixpkgs/pull/29205. Then that PR was closed
and a new one opened, https://github.com/NixOS/nixpkgs/pull/29503,
effectively circumventing the review process. I don't agree with this
modification. Adding an option 'resolveLocalQueries' to tell the locally
running name server that it should resolve local DNS queries feels
outright nuts. I agree that the current state is unsatisfactory and that
it should be improved, but this is not the right way.
(cherry picked from commit 23a021d12e8f939cd0bfddb1c7adeb125028c1e3)
When the user specifies the networking.nameservers setting in the
configuration file, it must take precedence over automatically
derived settings.
The culprit was services.bind that made the resolver set to
127.0.0.1 and ignore the nameserver setting.
This patch adds a flag to services.bind to override the nameserver
to localhost. It defaults to true. Setting this to false prevents the
service.bind and dnsmasq.resolveLocalQueries settings from
overriding the users' settings.
Also, when the user specifies a domain to search, it must be set in
the resolver configuration, even if the user does not specify any
nameservers.
(cherry picked from commit 670b4e29adc16e0a29aa5b4c126703dcca56aeb6)
This commit was accidentally merged to 17.09 but was intended for
master. This is the cherry-pick to master.
Previously services depending on network-online.target would wait until
dhcpcd times out if it was enabled and a static network address
configuration was used. Setting the default gateway statically is enough
for the networking to be considered online.
This also adjusts the relevant networking tests to wait for
network-online.target instead of just network.target.
For various reasons, big Nix attrsets look ugly in the generated manual
page[1]. Use literalExample to fix it.
[1] Quotes around attribute names are lost, newlines inside multi-line
strings are shown as '\n' and attrs written on multiple lines are joined
into one.
When keys get refreshed a folder with the permissions of the root user
get created in the home directory of the user dnscrypt-wrapper. This
prevents the service from restarting.
In addition to that the parameters of dnscrypt-wrapper have
changed in upstream and in the newly packaged software.
This commit readds and updates the 1.x package from 1.1.4 to 1.1.6 which
also includes the needed command for migrating to 2.x
The module is adjusted to the version change, defaulting to radicale2 if
stateVersion >= 17.09 and radicale1 otherwise. It also now uses
ExecStart instead of the script service attribute. Some missing dots at
the end of sentences were also added.
I added a paragraph in the release notes on how to update to a newer
version.
Couple of changes:
- move home to /var/lib/ddclient so we can enable ProtectSystem=full
- do not stick binary into systemPackages as it will only run as a daemon
- run as dedicated user/group
- document why we cannot run as type=forking (output is swallowed)
- secure things by running with ProtectSystem and PrivateTmp
- .pid file goes into /run/ddclient
- let nix create the home directory instead of handling it manually
- make the interval configurable
```Tinc```'s pid file has more info than just a pid
```
# cat /run/tinc.dmz.pid
12209 7BD4A657B4A04364D268D188A0F4AA972A05247D802149246BBE1F1E689CABA1 127.0.0.1 port 656
```
so ```systemd``` fails to parse it.
It results in long (re)start times when ```systemd``` waits for a correct pid file to appear.
Do the right thing, and use multiple interfaces for policy routing. For example, WireGuard interfaces do not allow multiple routes for the same CIDR range.
Fixes https://github.com/NixOS/nixpkgs/issues/27996.
Updates instructions for generating hashes passwords for use in a
Mosquitto password file. Using `mosquitto_passwd` to generate these
hashes is a little less convenient, but the results are more likely to
be compatible with the mosquitto daemon.
As far as I can tell, the hashes generated with `mkpassd` did not work
as intended. But this may have been hidden by another bug:
https://github.com/NixOS/nixpkgs/issues/27130.
Related to https://github.com/NixOS/nixpkgs/issues/27130.
Adds an option to NixOS configuration option to have Mosquitto use the
password file that it generates. When this option is false the
Mosquitto server will accept login attempts with any username and any
password. This option defaults to false because this matches the
behavior of the service prior to the introduction of this option.
When the `services.mosquitto.checkPasswords` is true, the server will
only accept valid usernames and passwords.
This adds a convenient per-peer option to set the routing table that associated routes are added to. This functionality is very useful for isolating interfaces from the kernel's global routing and forcing all traffic of a virtual interface (or a group of processes, via e.g. "ip rule add uidrange 10000-10009 lookup 42") through Wireguard.
The systemd service file shipped with strongswan has strongswan started after `network-online`. It turns out that this is for good reason: failure to connect on boot otherwise.
See this thread on the mailing list, which my colleague initiated after finding that our NixOS strongswan config wouldn't connect on boot:
https://lists.strongswan.org/pipermail/users/2017-January/010359.html
Tested on a local config (which has the strongswan service config overridden).
* lib: introduce imap0, imap1
For historical reasons, imap starts counting at 1 and it's not
consistent with the rest of the lib.
So for now we split imap into imap0 that starts counting at zero and
imap1 that starts counting at 1. And imap is marked as deprecated.
See c71e2d4235 (commitcomment-21873221)
* replace uses of lib.imap
* lib: move imap to deprecated.nix
nsd by default logs _both_ to syslog and to standard error which results
in all the messages ending up in the journal twice, the ones from stderr
with an ugly timestamp sticked in front of them.
This adds configuration options for the bind package so that the
interfaces that bind listens on can be configured rather than just
hardcoded as any. The default values preserve the old behavior to be
backwards compatible.
* tinc: Mention in docs that the host name may not be used verbatim.
Source:
5c344f2976/src/net_setup.c (L341)
* tinc: also replaces non-alphanumeric characters.
error now adds the zone file in the output which makes 'reasonable' debugging possible!

Release notes are available at https://www.openssh.com/txt/release-7.5.
Mostly a bugfix release, no major backwards-incompatible changes.
Remove deprecated `UsePrivilegeSeparation` option,
which is now mandatory.
AFAICT, this issue only occurs when sshd is socket-activated. It turns
out that the preStart script's stdout and stderr are connected to the
socket, not just the main command's. So explicitly connect stderr to
the journal and redirect stdout to stderr.
This reverts commit 1a74eedd07. It
breaks NixOps, which expects that
rm -f /etc/ssh/ssh_host_ed25519_key*
systemctl restart sshd
cat /etc/ssh/ssh_host_ed25519_key.pub
works.
This option was initially added to make it easier to use an
up-to-date list, but now that we always use an up-to-date list
from upstream, there's no point to the option.
From now on, you can either use a resolver listed by dnscrypt
upstream or a custom resolver.
Removes tcpOnly and ephemeralKeys: reifying them as nixos
options adds little beyond improved discoverability. Until
17.09 we'll automatically translate these options into extraArgs
for convenience.
Unless reifying an option is necessary for conditional
computation or greatly simplifies configuration/reduces risk of
misconfiguration, it should go into extraArgs instead.
Newer versions of DNSCrypt proxy *can* cache lookups (via
plugin); make the wording more neutral wrt. why one might want
to run the proxy in a forwarding setup.
It'd be better to do the update as an unprivileged user; for
now, we do our best to minimize the surface available. We
filter mount syscalls to prevent the process from undoing the fs
isolation.
Resolve download.dnscrypt.org using hostip with a bootstrap
resolver (hard-coded to Google Public DNS for now), to ensure
that we can get an up-to-date resolver list without working name
service lookups. This makes us more robust to the upstream
resolver list getting out of date and other DNS configuration
problems.
We use the curl --resolver switch to allow https cert validation
(we'd need to do --insecure if using just the ip addr). Note
that we don't rely on https for security but it's nice to have
it ...
Use mkMerge to make the code a little more ergonomic and easier
to follow (to my eyes, anyway ...). Also take the opportunity
to do some minor cleanups & tweaks, but no functional changes.
Set `networking.networkmanager.wifi.macAddress` or `networking.networkmanager.ethernet.macAddress`
to one of these values to change your macAddress.
* "XX:XX:XX:XX:XX:XX": set the MAC address of the interface.
* "permanent": use the permanent MAC address of the device.
* "preserve": don’t change the MAC address of the device upon activation.
* "random": generate a randomized value upon each connect.
* "stable": generate a stable, hashed MAC address.
See https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/ for more information
reason:
- We currently have an open discussion regarding a more modular
firewall (https://github.com/NixOS/nixpkgs/issues/23181) and
leaving null makes future extension easier.
- the current default might not cover all use cases (different ssh port)
and might break setups, if applied blindly
When dhcpcd instead of networkd is used, the network-online.target behaved
the same as network.target, resulting in broken services that need a working
network connectivity when being started.
This commit makes dhcpcd wait for a lease and makes it wanted by
network-online.target. In turn, network-online.target is now wanted by
multi-user.target, so it will be activated at every boot.
Recent versions of libreswan seem to omit this file, but it may be added/changed in the future. It is silly to have the service fail because a file is missing that only enriches the environment.
This fixes an issue where `nixops deploy` wouldn't restart the chrony
service when the chrony configuration changed, because it wouldn't
detect that `/etc/chrony.conf` was a dependency of the chrony service.
20e81f7c0d prevented key generation in
`preStart`, leaving the service broken for the case where the user has
no pre-existing key.
Eventually, we ought to store the state elsewhere so that `/etc` can be
read-only but for now we fix this the easy way.
