SVC(8)                                                     SVC(8)

     NAME
          svc: auth, net, registry, rstyx, styx - start Inferno
          network services

     SYNOPSIS
          svc/net
          svc/auth
          svc/registry
          svc/rstyx
          svc/styx

     DESCRIPTION
          The directory /dis/svc contains several sh(1) scripts to
          start network listeners (see listen(1)) that give remote
          hosts access to specific Inferno services on the current
          host.  The scripts can be edited to suit (or configure them-
          selves to suit) the requirements of a particular site.

          A host that is not an authentication server and wishes to
          start the usual network services can simply invoke svc/net,
          which runs all the others except authentication.  Authenti-
          cation servers should normally run svc/auth instead, to
          start local name and authentication services, and a listener
          for each authentication service but not file service or
          remote execution.

          Auth must be run (only) on a host that is to act as an
          authentication server, providing signing and other authenti-
          cation services to itself and the network.  The files
          /keydb/signerkey, created by createsignerkey(8), and
          /keydb/keys, managed by changelogin(8), must exist.  If so,
          auth starts keyfs(4), which prompts for the password that
          protects /keydb/keys, the file of secrets shared with regis-
          tered users.  If the key file is empty, the confirmed pass-
          word will be used in future to encrypt and decrypt the file;
          otherwise the password must match the one used to encrypt
          the key file.  If the password is valid, listeners are
          started for keysrv(4), to allow passwords to be changed
          remotely, logind(8), to provide signed certificates, and
          signer(8). Note that although an authentication server must
          be present to run getauthinfo(8) to obtain credentials to
          access another service, once those have been issued, the
          recipient can subsequently present them (if still valid) to
          access that service without further involvement by the ser-
          vice (ie, it need not then be running).  See changelogin(8)
          for the user registration program, which can be used once
          auth has started.

          Registry starts the dynamic service registry (see
          registry(4)) if it is not already running, putting it at the

          conventional location for the local registry, /mnt/registry.
          Initial (static) service descriptions are taken from
          /lib/ndb/registry if it exists.  It then starts a listener
          to give other hosts access to the registry as a Styx service
          at tcp!*!registry, normally port 6675.

          Rstyx listens for incoming calls to the rstyx service, and
          invokes rstyxd(8) to deal with each one.

          Styx listens for incoming calls to the styx service, and for
          each one, authenticates the caller, then calls export(4) to
          export the current root.

     FILES
          /keydb/keys       encrypted file containing user secrets
          /keydb/signerkey  private key of authentication server
