.Sh DESCRIPTION
|
||||
Connections to a NetWare server can be created and used independently from
|
||||
.Xr mount_nwfs 8
|
||||
command. Connection can be created by any user. Each user can have multiple
|
||||
connections, but NetWareServer:NetWareUser pair should be unique.
|
||||
.Pp
|
||||
The
|
||||
.Nm ncplogin
|
||||
command used to create permanent connection to a NetWare server. Permanent
|
||||
connection will stay connected even if no applications use it. This allows
|
||||
user to run different ncp* programs without specifying file server and user
|
||||
to use. This connection can be destroyed by
|
||||
.Xr ncplogout 1
|
||||
command.
|
||||
.Pp
|
||||
Upper case options described in this manual are common for other ncp* programs
|
||||
and referred as
|
||||
.Ar connection options.
|
||||
Options
|
||||
.Fl U
|
||||
and
|
||||
.Fl S
|
||||
are mutually exclusive with
|
||||
.Ar /server:user
|
||||
syntax.
|
||||
.Pp
|
||||
The options are:
|
||||
.Bl -tag -width indent
|
||||
.It Fl S Ar server
|
||||
name of NetWare server to connect. This affect only IPX severs for native IP
|
||||
see
|
||||
.Fl A
|
||||
option.
|
||||
.It Fl U Ar user
|
||||
name of user used in login sequence.
|
||||
.It Fl A Ar host
|
||||
connect to NetWare/IP server, specified by host.
|
||||
.It Fl C
|
||||
don't convert password to uppercase.
|
||||
.It Fl D
|
||||
Marks connection as primary. Can be used to modify already established
|
||||
connection. Only
|
||||
.Nm
|
||||
program accept that option.
|
||||
.It Fl I Ar signature_level
|
||||
try to use
|
||||
.Ar signature_level .
|
||||
.Bd -literal -offset indent
|
||||
Value Meaning
|
||||
0 disable signatures
|
||||
1 enable, use if server require them.
|
||||
2 ask server for signing, but agree to work without.
|
||||
3 signatures are required.
|
||||
.Ed
|
||||
Please note that only packet headers signing are implemented.
|
||||
.It Fl M Ar mode
|
||||
Just like files connections can be shared by users. The bits in
|
||||
.Ar mode
|
||||
argument behaves much like file permissions:
|
||||
.Bd -literal -offset indent
|
||||
Mask Meaning
|
||||
4 READ - connection will be visible.
|
||||
2 WRITE - connection can be closed/modified
|
||||
1 EXECUTE - user allowed to execute requests.
|
||||
.Ed
|
||||
By default connection created with mode 0700 and only owner can do
|
||||
anything with it. If you want to share the connection, for example with group
|
||||
you may specify 0750 value. This means group can do NCP request, but can't
|
||||
destroy connection. When user doesn't explicitly specify server to use, ncp*
|
||||
programs try to find suitable connection in the next order:
|
||||
.Pp
|
||||
1. Try to find connection owned by user. If there is more than one such
|
||||
connection it try to figure out which is primary. Primary flag controlled
|
||||
by
|
||||
.Fl D
|
||||
option.
|
||||
.Pp
|
||||
2. If previous fail, first shared connection will be used.
|
||||
.It Fl N
|
||||
don't ask for a password. While loading
|
||||
.Nm
|
||||
reads ~/.nwfsrc file to get additional configuration parameters and
|
||||
password. If no password found for the specified SERVER:USER pair,
|
||||
.Nm
|
||||
prompts for it.
|
||||
.It Fl O
|
||||
Just like files, connection has
|
||||
.Ar owner and
|
||||
.Ar group
|
||||
attributes. Newly created connection takes
|
||||
.Ar owner
|
||||
parameter from creator's userid and
|
||||
.Ar group
|
||||
paramter
|
||||
from creator's primary group.
|
||||
This can be overrided with this option. Only superuser can override an
|
||||
.Ar owner
|
||||
parameter.
|
||||
.It Fl P
|
||||
Marks connection as permanent.
|
||||
.Nm
|
||||
always create permanent connection. This option can be used in other ncp*
|
||||
programs.
|
||||
.It Fl R Ar retry_count
|
||||
specifies number of retries before drop the connection. The default value is 10.
|
||||
|
||||
Note: after connection marked 'BAD' each request will try to restore it.
|
||||
This process restore only NCP connection, but do not reopen any opened files.
|
||||
.It Fl W Ar timeout
|
||||
This specifies server request timeout in seconds. The default is 5 seconds.
|
||||
.It Ar /server:user
|
||||
This syntax provided for the sake of simplicity and mutually exclusive with
|
||||
.Fl S
|
||||
and
|
||||
.Fl U
|
||||
options.
|
||||
.El
|

.Sh FILES

|
||||
keeps description for each connection. See
|
||||
.Xr nwfsrc 8
|
||||
for details.
|
||||
|
||||
.Sh NOTES
|
||||
Low level connection management performed by ncp.ko module. For an IPX
|
||||
protocol it is also necessary to load IPXrouted program.
