Samba
Motivation
This guide will help you on how to use samba on nixos.
cifs mount
The following snippets shows how to mount a CIFS (Windows) share in NixOS.
Replace all <FIELDS> with concrete values:
{
fileSystems."/mnt/share" = {
device = "//<IP_OR_HOST>/path/to/share";
fsType = "cifs";
options = let
# this line prevents hanging on network split
automount_opts = "x-systemd.automount,noauto,x-systemd.idle-timeout=60,x-systemd.device-timeout=5s,x-systemd.mount-timeout=5s";
in ["${automount_opts},credentials=/etc/nixos/smb-secrets"];
};
}
Also create /etc/nixos/smb-secrets with the following content (domain= can be optional)
username=<USERNAME>
domain=<DOMAIN>
password=<PASSWORD>
excerpt of /etc/nixos/configuration.nix
services.samba.enable = true;
services.samba.securityType = "share";
services.samba.extraConfig = ''
workgroup = WORKGROUP
server string = smbnix
netbios name = smbnix
security = share
#use sendfile = yes
#max protocol = smb2
[rw-files]
comment = Temporary rw files
path = /storage
read only = no
writable = yes
public = yes
'';
If your firewall is enabled, or if you consider enabling it:
networking.firewall.enable = true;
networking.firewall.allowPing = true;
networking.firewall.allowedTCPPorts = [ 445 139 ];
networking.firewall.allowedUDPPorts = [ 137 138 ];

Tip
In order to affect your system by your nix-language-specific changes you have to evaluate it, run (as root):
# nixos-rebuild switch |
samba should startup afterwards
stopping/restarting the services
# systemctl stop samba
# systemctl start samba
# systemctl restart samba
