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 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 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 seconds
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.
EXAMPLES
To see kremvax’s and deepthought’s files in
/n/kremvax
and
/n/deepthought:
9fs kremvax
9fs hhgttg /n/deepthought
FILES
/srv/*
ports to file systems and servers posted by
srv
and
9fs

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