Both commands first authenticate the incoming call using keyring-auth(2) via security-auth(2). On successful authorisation, the server sets its user identity to that of the caller, and the client can request that a digest and/or encryption algorithm be applied using ssl(3) to protect the data exchanged with the server. Each alg names a digest or encryption algorithm that the server will allow the client to use, in any form accepted by ssl; the special name none is usually listed, to allow the client to choose not to use ssl.
Styxd provides Styx file service to its client. Having authorised the client and optionally established ssl, as described above, it exports its name space (usually the name space inherited from svc(8)) on the connection using Sys->export (see sys-dial(2)).
Rstyxd provides a remote-execution service. Having authorised the client and optionally established ssl, as described above, it reads a single line from its standard input. The line contains a decimal value that is the count of the number of bytes that follow, which rstyxd reads as a utf(6)-encoded string. The string contains a command, which is parsed into arguments, following the quoting conventions of sh(1). The first argument is the command name. Rstyxd prepares a modified name space in which to run the command. It mounts the connection (standard input) on /n/client, binds /n/client/dev onto /dev, and opens the new /dev/cons (ie, the remote client's /dev/cons) on file descriptors 0, 1 and 2. Finally, it executes the command.
