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.
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.
