{{Tip|The best test to check that the SSH access works for Nix is to run on your local machine:

<code>nix store ~~ping~~ --store ssh://<REMOTE-BUILDER></code>

<code>nix store info --store ssh://<REMOTE-BUILDER></code>

Where <code><REMOTE-BUILDER></code> is the remote builder's IP address, host address or whatever name you configure in ~/.ssh/config or /root/.ssh/config, including the user@ prefix.}}

* How do I know why my builds aren't being distributed?

** Run <code>nix build -vvvvvvvvv 2>&1 | less</code> and search for <code>decline</code>.

* I can <code>nix store ~~ping~~</code> but the build doesn't distribute.

* I can <code>nix store info</code> but the build doesn't distribute.

** If on NixOS, Check that <code>nix store ~~ping~~</code> ~~command~~ works when run as root.

** If on NixOS, Check that <code>nix store info</code> works when run as root.

** If you configured builders on the command line (with <code>--builders</code>), make sure your account is in <code>nix.trustedUsers</code> in <code>/etc/nixos/configuration.nix</code>. ~~Only~~ <code>/etc/nix/nix.conf</code> is taken into account ~~otherwise~~.

** If you configured builders on the command line with the <code>--builders</code> flag, make sure your account is in <code>nix.trustedUsers</code> in <code>/etc/nixos/configuration.nix</code>. Otherwise only <code>/etc/nix/nix.conf</code> is taken into account.

* I can ~~ping the~~ store as root, but I'm getting "broken pipe" errors when trying to distribute.

* I can <code>nix store info</code> as root, but I'm getting "broken pipe" errors when trying to distribute.

** You may have hit bug {{Issue|46038}}. Add <code>nix.distributedBuilds = true;</code> to <code>configuration.nix</code> and <code>nixos-rebuild switch</code>.
