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: +<PRE> + XPA xpa1 gs 838e2f67:1262 eric + XPA xpa2 gs 838e2f67:1266 eric + XPA xpa1 gs 838e2f67:2523 john + XPA xpa2 gs 838e2f67:2527 john +</PRE> +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. + +<P> +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: +<PRE> + xpaget -u john xpa1 +</PRE> +he will access John's xpa1 access point.Use "*" to access all users +on a given machine: +<PRE> + xpaget -u "*" xpa1 +</PRE> +Note that the <A HREF="./env.html">XPA Environment Variable</A> +XPA_NSUSERS can be used to specify the default list of users to +process: +<PRE> + setenv XPA_NSUSERS "eric,john" +</PRE> +will cause access points from both "eric" and "john" to be processed +by default. + +<!-- =section xpausers SEE ALSO --> +<!-- =text See xpa(n) for a list of XPA help pages --> +<!-- =stop --> + +<P> +<A HREF="./help.html">Go to XPA Help Index</A> + +<H5>Last updated: September 10, 2003</H5> +</BODY> +</HTML> |
