Controller worker

Controller worker is used to manage rspamd stats, to learn rspamd and to serve WebUI.

Internally, the controller worker is just a web server that accepts requests and sends replies using JSON serialization. Each command is defined by URL. Some commands are read only and are considered as unprivileged whilst other commands, such as maps modification, config modifications and learning requires higher level of privileges: enable level. The differece between levels is specified by password. If only one password is specified in the configuration, it is used for both type of commands.

Controller configuration

Rspamd controller worker supports the following options:

  • password: password for read-only commands
  • enable_password: password for write commands
  • secure_ip: list or map with IP addresses that are treated as secure so all commands are allowed from these IPs without passwords
  • static_dir: directory where interface static files are placed (usually ${WWWDIR})
  • stats_path: path where controller save persistent stats about rspamd (such as scanned messages count)

Encryption support

To generate a keypair for the scanner you could use:

rspamadm keypair -u

After that keypair should appear as following:

keypair {
    pubkey = "tm8zjw3ougwj1qjpyweugqhuyg4576ctg6p7mbrhma6ytjewp4ry";
    privkey = "ykkrfqbyk34i1ewdmn81ttcco1eaxoqgih38duib1e7b89h9xn3y";
}

You can use its public part thereafter when scanning messages as following:

rspamc --key tm8zjw3ougwj1qjpyweugqhuyg4576ctg6p7mbrhma6ytjewp4ry <file>

Passwords encryption

Rspamd now suggests to encrypt passwords when storing them in a configuration. Currently, it uses PBKDF2-Blake2 function to derive key from a password. To encrypt key, you can use rspamadm pw command as following:

rspamadm pw
Enter passphrase: <hidden input>
$1$cybjp37q4w63iogc4erncz1tgm1ce9i5$kxfx9xc1wk9uuakw7nittbt6dgf3qyqa394cnradg191iqgxr8kb

You can use that line as password and enable_password values.
