rcpu, rimport, rexport, rconnect – connection to CPU server|
rcpu [ –u user ] [ –k keypattern ] [ –P patternfile ] [ –p ] [ –h host
] [ –c cmd arg ... ] |
rimport [ –abcCnq ] [ –s name ] [ –u user ] [ –k keypattern ] [ –p ] host tree [ mountpoint ]
rexport [ –abcCnq ] [ –s remotename ] [ –m remotemtpt ] [ –u user ] [ –k keypattern ] [ –P patternfile ] [ –p ] tree host [ remotecmd arg ... ]
rconnect [ –u user ] [ –k keypattern ] [ –p ] host remotescript localcommand
Rcpu runs commands from rc(1) on a cpu server with the local namespace
exported to the remote side under /mnt/term. The current directory,
interrupt notes, standard file descriptors 0,1,2 and /dev/cons
are passed to the remote side. The command to run can be passed
with –c cmd arg ..., otherwise an
interactive shell is started. The user's profile is run before
the command with $service set to cpu to allow further customization
of the environment (see rc(1) for more information). The cpu server
can be specified with –h host, otherwise it defaults to the environment
variable $cpu or is looked up from ndb(6). |
Rimport mounts a remote directory tree from a cpu server host into the local namespace at mountpoint. When mountpoint is omitted, it is set the same as tree. When the –s name option is present, the service is also posted to /srv/name allowing it to be mounted in other namespaces.
Rexport is the reverse of rimport, exporting a local directory tree to the server host and optionally executing remotecmd arg on the server side after posting the service to /srv/remotename or mounting it at remotemtpt.
Rconnect is a helper program handling client side connection setup for the commands listed above. The rcpu protocol starts by setting up a mutual authenticated and encrypted TLS connection using tlssrv(8) followed by the client sending an rc(1) remotescript file to the server which gets executed under the authenticated user with file descriptors 0,1,2 cross connected to file descriptors 0,1 of the client side running localcommand over the encrypted connection.
The common options are:
rc(1), cpu(1), con(1), import(4), exportfs(4), tlssrv(8), aan(8)|
