rstyxd - Styx-based remote execution and file service


auxi/rstyxd alg ...


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.

Rstyxd is normally started by svc(8) in response to incoming network calls. It expects the standard input to be connected to the client; unusually, it is both read and written. It first authenticates 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.
