SRV(4)									SRV(4)

       srv, srvold9p, 9fs, srvssh - start network file service

       srv  [  -abcCemnq  ]  [ -s seconds ] [net!]system[!service] [ srvname [
       mtpt ] ]

       srvssh [ -r ] [ -R ] [ -s ] [ -u u9fspath ] system [ srvname [ mtpt ] ]

       9fs [net!]system [mountpoint]

       srvold9p [ -abcCdF ] [ -p servicename ] [ -s | -m  mountpoint  ]	 [  -u
	    user ] [ -x command | -n network-addr | -f file ]

       Srv dials the given machine and initializes the connection to serve the
       9P protocol.  By default, it connects to the (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 omit‐
       ted, 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 sup‐
       presses 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	estab‐
       lishing	the  connection before posting and mounting it.	 This is some‐
       times 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 mount‐
       point, if given; otherwise they are mounted on  /n/system.   If	system
       contains	 characters, only the last element of system is used in the /n

       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 spe‐
       cial ones are:

       -d     Enable debugging.

       -F     Insert a special (internal) filter process to the connection  to
	      maintain	message boundaries; usually only needed on TCP connec‐

       -p servicename
	      Post the service under srv(3) as /srv/servicename.

       -u user
	      When connecting to the remote server, log	 in  as	 user.	 Since
	      srvold9p	does  no  authentication, and since new kernels cannot
	      authenticate to old services, the likeliest  value  of  user  is

       -x command
	      Run command and use its standard input and output as the 9P ser‐
	      vice connection.	If the	command	 string	 contains  blanks,  it
	      should be quoted.

       -n network-addr
	      Dial network-addr to establish the connection.

       -f file
	      Use file (typically an existing srv(3) file) as the connection.

       Srvold9p	 is  run  automatically	 when a cpu(1) call is received on the
       service port for the old protocol.

       To  see	kremvax's  and	 deepthought's	 files	 in   /n/kremvax   and

	      9fs kremvax
	      9fs hhgttg /n/deepthought

       To mount as user none a connection to an older server kgbsun:

	      srvold9p -u none -m /n/kgbsun -p kgbsun -n il!kgbsun

       Other windows may then mount the connection directly:

	      mount /srv/kgbsun /n/kgbsun

       To  connect  to	an  instance  of  the  Unix server u9fs(4) started via

	      srvssh unix

       /srv/* ports to file systems and servers posted by srv and 9fs


       bind(1), auth(2), dial(2), srv(3),  exportfs(4),	 import(4),  ftpfs(4),

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