xpaaccess returns \*(L"yes\*(R" to stdout (with a return error code if 1) if there are
existing \s-1XPA\s0 access points that match the
template
(and optional access type: g,i,s). Otherwise, it returns \*(L"no\*(R" (with a
return error code of 0). If \-n is specified, the number of matches is
returned instead (both to stdout and in the returned error code). If
\&\-v is specified, each access point is displayed to stdout instead of
the number of matches.
.PP
By default, xpaaccess simply contacts the xpans name server to find
the list of registered access points that match the specified
template. It also checks to make sure the specified types are
supported by that access point. This is the fastest way to determine
available access points. However, an access point might registered but
not yet available, if, for example, the server program has not entered
its event loop to process \s-1XPA\s0 requests. To find access points that are
guaranteed to be available for processing, use the \-c (contact)
switch. With this switch, xpaaccess contacts each matching \s-1XPA\s0 server
(rather than the name server) to make sure the registered access point
really is ready for processing. In this mode, if an access point is
registered but not available, xpaaccess will pause for a period of
time equal to the \s-1XPA_LONG_TIMEOUT\s0, in order to give the server a
chance to ready itself. By default, this timeout is 30 seconds. You
can shorten the time of delay using the \-t \*(L"short,long\*(R" switch. For
example, to shorten the delay time to 2 seconds, use:
.PP
.Vb 1
\& xpaaccess \-c \-t "2,2" ds9
.Ve
.PP
The first argument is the short delay value, and is ignored in this
operation. The second is the long delay timeout.
.PP
Note also that the default xpaaccess method (no \-c switch) does not
check access control (acls) but rather only checks whether the access
point is both registered with the xpans name server and provides the
specified type of access. In other words, the default xpaaccess could
return 'yes' when you might not actually have access. This mode also
always returns 'yes' for the xpans name server itself, regardless of
whether the name server is active. The \-c (contact) switch, which
contacts the access point directly, can and does check the access
control (only for servers using version 2.1 and above) and also
returns the real status of xpans.
