.TH RSTYXD 8 .SH NAME rstyxd \- Styx-based remote execution and file service .SH SYNOPSIS .B auxi/rstyxd .I alg \&... .SH DESCRIPTION .PP .I Rstyxd provides a remote-execution service. Having authorised the client and optionally established .IR 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 .I rstyxd reads as a .IR utf (6)-encoded string. The string contains a command, which is parsed into arguments, following the quoting conventions of .IR sh (1). The first argument is the command name. .I Rstyxd prepares a modified name space in which to run the command. It mounts the connection (standard input) on .BR /n/client , binds .BR /n/client/dev onto .BR /dev , and opens the new .B /dev/cons (ie, the remote client's .BR /dev/cons ) on file descriptors 0, 1 and 2. Finally, it executes the command. .PP .I Rstyxd is normally started by .IR 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 .IR keyring-auth (2) via .IR 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 .IR ssl (3) to protect the data exchanged with the server. Each .I alg names a digest or encryption algorithm that the server will allow the client to use, in any form accepted by .IR ssl ; the special name .B none is usually listed, to allow the client to choose not to use .IR ssl . .SH FILES .TF /usr/user/keyring/default .TP .B /n/client mount point used by .I rstyxd .TP .BI /usr/ user /keyring/default server's authentication data when .IR svc (8) run as given .I user .SH SOURCE .B /appl/cmd/auxi/rstyxd.b .SH SEE ALSO .IR keyring-auth (2), .IR security-auth (2), .IR getauthinfo (8)
