.TH OEXPORTFS 4 .SH NAME oexportfs \- legacy exportfs for cpu and import .SH SYNOPSIS .PP .B oexportfs [ .I options ] .SH DESCRIPTION .I Oexportfs is older version of the .IR exportfs (4) program that handles an initial protocol to establish a root directory for the exported name space. It also provides authentication and encryption using the .IR ssl (3) device. .PP It is used exclusively by the deprecated .IR cpu (1) and .IR import (4) services. .PP The options are: .TP .B -d -f \fIdbgfile Log all 9P traffic to .I dbgfile (default .BR /tmp/exportdb ). .TP .B -P \fIpatternfile Restrict the set of exported files. .I Patternfile contains one regular expression per line, to be matched against path names relative to the current working directory and starting with .BR / . For a file to be exported, all lines with a prefix .B + must match and all those with prefix .B - must not match. .TP .B -R Make the served name space read only. .TP .B -r \fIroot Serve the name space rooted at .IR root . .TP .B -S \fIservice Serve the result of mounting .IR service . A separate mount is used for each .IR attach (5) message, to correctly handle servers in which each mount corresponds to a different client .IR e.g. , ( .IR rio (4)). .TP .B -s equivalent to .B -r .BR / ; kept for compatibility. .TP .B -m \fImsize Set the maximum message size that .I oexportfs should offer to send (see .IR version (5)); this helps tunneled 9P connections to avoid unnecessary fragmentation. .TP .B -A \fIaddress Use the network .I address to announce .IR aan (8) connections, if requested by the initial protocol. .TP .B -a Authenticate the user with the .I p9any protocol before running the regular .I oexportfs session; used when .I oexportfs is invoked to handle an incoming network connection. .I Exportfs creates a new name space for each connection, using .B /lib/namespace by default (see .IR namespace (6)). .TP .B -B \fIaddress Dial .IR address , authenticate as a .I p9any client, and then serve that network connection. Requires setting the root of the name space with .B -r or .BR -s . The remote system should run .B import .B -B to handle the call. See .IR import (4) for an example. .TP .B -e '\fIenc auth\fL' Set the encryption and authentication algorithms to use for encrypting the wire traffic (see .IR ssl (3)). The defaults are .B rc4_256 and .BR sha1 . .TP .B -N \fInsfile Serve the name space described by .IR nsfile . .TP .B -n Disallow mounts by user .BR none . .EE .SH SOURCE .B /sys/src/cmd/exportfs/oexportfs.c .SH SEE ALSO .IR dial (2), .IR exportfs (4), .IR import (4), .IR aan (8), .IR listen (8)
