.TH SRV 4 .SH NAME srv, srvtls, srvssh, 9fs \- start network file service .SH SYNOPSIS .B srv [ .B -abcCemnNq ] [ .B -s .I seconds ] .RI [ net !] system\c .RI [! service ] [ .I srvname [ .I mtpt ] ] .PP .B srvtls [ .B -abcCnq ] [ .B -k .I keyspec ] .RI [ net !] system\c .RI [! service ] [ .I srvname [ .I mtpt ] ] .PP .B srvssh [ .B -r ] [ .B -R ] [ .B -s ] [ .B -u .I u9fspath ] .I system [ .I srvname [ .I mtpt ] ] .PP .B 9fs .RI [ net !] system .RI [ mountpoint ] .SH DESCRIPTION .I Srv dials the given machine and initializes the connection to serve the 9P protocol. By default, it connects to the .L 9fs (9P) service, which for TCP is port 564. It then creates in .B /srv a file named .IR srvname . Users can then .B mount (see .IR bind (1)) the service, typically on a name in .BR /n , to access the files provided by the remote machine. If .I srvname is omitted, the first argument to .I srv is used. Option .B m directs .I srv to mount the service on .BI /n/ system or onto .I mtpt if it is given. Option .B q suppresses complaints if the .B /srv file already exists. The .BR a , .BR b , .BR c , .BR C , and .BR n , .B N options are used to control the mount flags as in .I mount (see .IR bind (1)). The .B e option causes .I srv to treat .I system as a shell command to be executed rather than an address to be dialed. The .B s option causes .I srv to sleep for the specified number of seconds after establishing the connection before posting and mounting it. This is sometimes needed by .IR srvssh . .PP The specified .I service must serve 9P. Usually .I service can be omitted; when calling some non-Plan-9 systems, a .I service such as .B u9fs must be mentioned explicitly. .PP The .I 9fs command does the .I srv and the .I mount necessary to make available the files of .I system on network .IR net . The files are mounted on .IR mountpoint , if given; otherwise they are mounted on .BI /n/ system\f1. If .I system contains .L / characters, only the last element of .I system is used in the .B /n name. .PP .I 9fs recognizes some special names, such as .B dump to make the dump file system available on .BR /n/dump . .I 9fs is an .IR rc (1) script; examine it to see what local conventions apply. .PP .I Srvtls is an .IR rc (1) command that uses .I tlsclient (see .IR tlssrv (8)) to establish an mutual authenticated and encrypted connection to the .I t9fs service which by default listens on tcp port 17020. .PP .I Srvssh is an .IR rc (1) command that connects to a remote Unix system via .IR ssh (1) and starts .BR u9fs . The .B -u option specifies the path to the .B u9fs binary on the remote system. (By default, an unrooted path of .B u9fs is used; if the binary is in the path of the remote SSH server, you don't need the .B -u option.) For information about the other options, see the introductory comment in .BR /rc/bin/srvssh . The arguments are the same as .IR srv . .SH EXAMPLES To see kremvax's and deepthought's files in .B /n/kremvax and .BR /n/deepthought : .IP .EX 9fs kremvax 9fs hhgttg /n/deepthought .EE .PP To connect to an instance of the Unix server .I u9fs started via .IR ssh (1): .IP .EX srvssh unix .EE .SH FILES .TF /srv/* .TP .B /srv/* ports to file systems and servers posted by .I srv and .I 9fs .SH SOURCE .B /sys/src/cmd/srv.c .br .B /rc/bin/9fs .br .B /rc/bin/srvssh .SH "SEE ALSO" .IR bind (1), .IR auth (2), .IR dial (2), .IR srv (3), .IR exportfs (4), .IR import (4), .IR ftpfs (4), .SH BUGS .I Srv does not explicitly report failures of .I auth_proxy (see .IR auth (2)); .I mount (see .IR bind (1)) does.
