You can test the setup via `nixops`. After installation, do
|
|
|
|
```
|
|
nixops create nixops/single-server.nix nixops/vbox.nix -d mail
|
|
nixops deploy -d mail
|
|
nixops info -d mail
|
|
```
|
|
|
|
You can then test the server via e.g. `telnet`. To log into it, use
|
|
|
|
```
|
|
nixops ssh -d mail mailserver
