X-Win32 Command-Line Feature
X-Win32 now offers a command-line feature that allows users to dynamically invoke
a session. This is useful in cases where there are multiple Unix/Linux servers and
you are using a server load-balancing utility.
Using this feature, an algorithm can be written to determine the best Linux/Unix
host (based upon system load) for a new session, and then use this information to direct
the user to the appropriate server. Suppose, for instance, that there are three Unix
servers on a local departmental network. After determining that "server 2" has the smallest
load, it is possible to direct a new user session to that server. This allows optimum server
utilization to be realized.
The command-line feature is used as follows:
XWin32.exe -m flags session_type args
| Where: |
|
Flags (one of the window modes must be chosen): |
|
|
M - Switch to multiple-window mode |
|
|
S - Switch to single-window mode |
|
|
D - Switch to default-window mode |
|
|
W - Show messages |
|
Session_type: XDMCP, REXEC, RSH, and SSH |
|
args (dependent on session type): |
|
|
Xdmcp Session: |
|
|
|
none - Use broadcast mode |
|
|
|
hostname - Use query mode to "host_name" |
|
|
|
hostname, hostname,... - Use multicast mode to all listed hosts |
|
|
|
~hostname - Use indirect mode |
|
|
Rexec, rsh, or ssh Sessions: |
|
|
|
hostname:userID::command |
| Examples: |
|
XWin32 -m WS XDMCP server2 |
|
XDMCP query-mode session to "Server2" showing messages and switching to single-window mode |
|
|
XWin32 -m WD REXEC apollo1:mike::/usr/bin/X11/xterm
-display $MYIP:$DNUM |
|
REXEC session to "apollo1" logging in as "mike" and starting an xterm using the current IP
address and isplay number. Use default window mode. |
