NAME
srv, srvtls, 9fs - start network file service
SYNOPSIS
srv [ -abcCemnNq ] [ -s seconds ] [net!]system[!service] [
srvname [ mtpt ] ]
srvtls [ -abcCnq ] [ -k keyspec ] [net!]system[!service] [
srvname [ mtpt ] ]
9fs [net!]system [mountpoint]
DESCRIPTION
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 cre-
ates 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, 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 sec-
onds after establishing the connection before posting and
mounting it.
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.
Srvtls is an rc(1) command that uses tlsclient (see
tlssrv(8)) to establish an mutual authenticated and
encrypted 9P connection to the t9fs service which by default
listens on tcp port 17020.

BUGS
Srv does not explicitly report failures of auth_proxy (see
auth(2)); mount (see bind(1)) does.
