Srv dials the given machine and initializes the connection to
serve the 9P protocol. By default, it connects to the 9fs (9P)
service, which for TCP is port 564. It then creates in /srv a
file named srvname. Users can then mount (see bind(1)) the service,
typically on a name in /n, to access the files provided by the
remote machine. If srvname is omitted, the first argument to srv
is used. Option m directs srv to mount the service on /n/system
or onto mtpt if it is given. Option q suppresses complaints if
the /srv file already exists. The a, b, c, C, and n options are
used to control the mount flags as in mount (see bind(1)). The
e option causes srv to treat system as a shell command to be executed
rather than an address to be dialed. The s option causes srv to
sleep for the specified number of seconds after establishing the
connection before posting and mounting it. This is sometimes needed
by srvssh. |
The specified service must serve 9P. Usually service can be omitted; when calling some non–Plan–9 systems, a service such as u9fs must be mentioned explicitly.
The 9fs command does the srv and the mount necessary to make available the files of system on network net. The files are mounted on mountpoint, if given; otherwise they are mounted on /n/system. If system contains / characters, only the last element of system is used in the /n name.
9fs recognizes some special names, such as dump to make the dump file system available on /n/dump. 9fs is an rc(1) script; examine it to see what local conventions apply.
Srvssh is an rc(1) command that connects to a remote Unix system via ssh(1) and starts u9fs(4). The –u option specifies the path to the u9fs binary on the remote system. (By default, an unrooted path of u9fs is used; if the binary is in the path of the remote SSH server, you don't need the –u option.) For information about the other options, see the introductory comment in /rc/bin/srvssh. The arguments are the same as srv.
Srvold9p is a compatibilty hack to allow Fourth Edition Plan 9
systems to connect to older 9P servers. It functions as a variant
of srv that performs a version translation on the 9P messages
on the underlying connection. Some of its options are the same
as those of srv; the special ones are:
–d Enable debugging.
Srvold9p is run automatically when a cpu(1) call is received on
the service port for the old protocol.
