NAME
     utswitch -  Sun Ray server selection and session listing

SYNOPSIS
     /opt/SUNWut/bin/utswitch  { -l  | -t   | -h  host  }   [  -k
     token ]  [ -s sid ]

DESCRIPTION
     The utswitch command allows switching a  Sun  Ray  appliance
     among  Sun Ray servers in a failover group. It can also list
     the existing sessions for the current token.    One  of  the
     following option flags must be specified: -l, -t, or -h. The
     utselect(1) command implements a GUI-based interface to this
     command.

OPTIONS
     The following options are supported by utswitch:

     -h host
           Force an explicit switch to the server  with  hostname
           host.

     -k token
           Specify the token id token to be  used  in  collecting
           session  information  from the servers in the failover
           group. The token normally used is the one connected to
           the current session.

     -l    List the servers accessible from the current  Sun  Ray
           appliance  for the current token and show any existing
           sessions on those servers. The token is  derived  from
           the serial number and type of a smart card if there is
           one inserted. Otherwise, the token is derived from the
           Ethernet  address  of the Sun Ray appliance. The first
           field of the output is the server name. The second  is
           the X display number if there is a logged-in user ses-
           sion, -1 if no session exists, or -2 if there is an  X
           session,  but the login screen is being displayed. The
           third field is the last connection time to an existing
           session, as a time value from the time(2) system call.
           If there is no  session,  the  third  field  indicates
           status from the host as:

                -1   Server is up, but there is no session.

                -2   No response received from the server.

                -3   No path from the Sun Ray to the server.

           The fourth field is 1 if the server is offline  and  0
           otherwise.

     -s sid
           Specify the session id sid of a session connected to a
           Sun  Ray appliance and perform the requested operation
           on that appliance. The default is to use  the  session
           id  of  the  current  session. Since session ids other
           than that of the current session are only available to
           userid  root,  this option is not useful for a general
           user.

     -t    Switch to the server whose session has the latest con-
           nection  time  among  the  existing  sessions  for the
           current token.  Normally  this  would  switch  to  the
           current  session,  so  it has limited usefulness. How-
           ever, it is useful in the case of logging  out  of  an
           existing  X  session and back to the login screen. The
           connection time of a logged out session is biased back
           in  time  so that that session will not be selected if
           there is an existing logged-in X  session  on  another
           server.  From  a  CDE  login screen, it is possible to
           force a call to utswitch -t by selecting  Reset  Login
           Screen  from  the  Options menu. This allows switching
           back to a logged-in  session  from  the  login  screen
           without having to log in.
