u9fs

there is a package on openbsd ports. it's outdated. don't use it.

$ git clone https://github.com/unofficial-mirror/u9fs
$ cd u9fs

apply this patch:

diff --git a/u9fs.c b/u9fs.c
index ea0391c..48e1e21 100644
--- a/u9fs.c
+++ b/u9fs.c
` -152,9 +152,9 ` char*       root;
 User*  none;
 Auth *authmethods[] = {        /* first is default */
+       &authnone,
        &authrhosts,
        &authp9any,
-       &authnone,
 };
 Auth *auth;

and build it:

$ make
$ doas make install

and add this to /etc/inetd.conf:

564     stream  tcp     nowait  root    /usr/local/bin/u9fs -l /var/log/u9fs.log /path/to/share

this runs a 9p server on port 564 (default) and reads from /path/to/share.

now enable and run inetd:

$ doas rcctl enable inetd
$ doas rcctl start inetd
