Two users can register the same XPA access points on the +same machine without conflict, because the user's username is +registered with each access point and, by default, programs such as +xpaget and xpaset only process access points of the appropriate user. +For example: + + XPA xpa1 gs 838e2f67:1262 eric + XPA xpa2 gs 838e2f67:1266 eric + XPA xpa1 gs 838e2f67:2523 john + XPA xpa2 gs 838e2f67:2527 john + +Here the users "eric" and "john" both have registered the access +points xpa1 and xpa2. When either "john" or "eric" retrieves +information from xpa1, they will process only the access point +registered in their user name. + + +If you want to access another user's XPA access points on a single +machine, use the -u [user] option on xpaset, xpaget, etc. For example, +if eric executes: + + xpaget -u john xpa1 + +he will access John's xpa1 access point.Use "*" to access all users +on a given machine: + + xpaget -u "*" xpa1 + +Note that the XPA Environment Variable +XPA_NSUSERS can be used to specify the default list of users to +process: + + setenv XPA_NSUSERS "eric,john" + +will cause access points from both "eric" and "john" to be processed +by default. + + + +=head1 SEE ALSO + + + +See xpa(n) for a list of XPA help pages + + + +=cut |
