- Ghost Multicast Server What's New - Version 5.1c (01-26-99)
- ======================================================================
-
- 1) Support for multicasting of multi-segment image files
- -----------------------------------------------------
- The Ghost Multicast Server can now handle split multi-segment image
- files. The Norton Ghost AUTONAME functionality is always used. All
- the image file segments MUST be located in the same directory as
- the first segment of the image file. (This file usually has a .GHO
- extension).
-
- 2) Support for image files greater than 2 GB
- -----------------------------------------
- Norton Ghost now supports image files greater than 2 GB. This is
- achieved by splitting the image into 2 GB segments. Therefore when a
- image file reaches 2 GB in size, a new file segment will be opened
- following the spanned image file naming conventions.
-
- For example, if the source disk contained 5 GB of data, and the image
- file was given as LARGE.GHO on the Ghost Multicast Server, the Ghost
- Multicast Server would create three files, LARGE.GHO (the first
- portion, 2GB), LARGE.001 (the second portion, 2GB) and LARGE.002
- (the third portion, 1GB) in the same directory.
-
- Existing files with a required segment file name will be overwritten.
- For example, if LARGE.002 already exists in the directory the image
- file is to be written to, it will be overwritten with no user
- prompt.
-
- 3) Ghost Multicasting Software version compatibility checking
- ----------------------------------------------------------
- Ghost Multicasting Software version compatibility checking has
- been added. Warnings will be shown on the Ghost client as follows:
-
- New Ghost Error 19923 - Multicast Read Error: The version of
- the multicast server may be incompatible. Please ensure that
- you are running version 5.1c beta 2 or later.
-
- New Ghost Error 19948 - Multicast server is an incompatible
- version. Please obtain an updated version of Ghost or the
- Ghost multicast server.
-
- 4) Improved performance over congested networks
- --------------------------------------------
- Multicast performance has been improved over congested networks.
-
- 5) Multicast Server buffer configuration options.
- ----------------------------------------------
- The Multicast Server's multicast buffer size held in memory can now
- be optionally configured through the -B[value] command line switch and
- through the Windows Ghost multicast server's options. The default
- multicast buffer size is 4 MB.
-
- Altering the buffer size will change:
- a) the amount of memory required by the multicast server to run
- b) the amount of tolerance for individual clients falling behind
- in the multicast session.
-
- Reducing the buffer size will reduce the memory requirements of the
- multicast server and reduce the delay tolerance levels. This
- may result in more clients being disconnected from the multicast
- session and is not recommended.
-
- Increasing the buffer size will increase the memory requirements.
- It will also increase the amount of time an individual client is
- allowed to fall behind in the multicast session and recover.
- Increasing the buffer size may reduce the number of clients
- failing half way through the multicast session with the
- error message "connection rest by the server". Increasing the
- buffer size is not recommended when the default buffer size
- allows successful operation.
-
- 6) Ability for Windows Multicast Server to restart multicast sessions
- ------------------------------------------------------------------
- The Windows Ghost Multicast Server (Ghostsrv.exe) now includes the
- ability to continuously loop multicast sessions. The DOS version
- (DOSGHSRV.EXE) does not have this functionality.
-
- This feature can be activated through the Windows Ghost Multicast Server
- -R command line switch or by selecting File, Options, Restart On Completion.
- Following a multicast session completion, the Windows Ghost Multicast Server
- will reset the multicast session and begin accepting clients using the same
- auto-start parameters and session details as the previous session.
- Command line usage example:
- GHOSTSRV c:\test123.gho sessionname -N10 -R
-
- 7) New multicast session auto-start parameter: timeout value
- ---------------------------------------------------------
- The Ghost Multicast Server now has the ability to specify a timeout
- value for the start of the multicast session.
-
- The Auto-Start Timeout box sets the maximum number of minutes the server
- will wait for a new client to connect before starting the session.
- For example, if the timeout was set to fifteen (15), the server will wait
- indefinitely until the first client is accepted. After the first client
- joins, the 15 minute count down is started. If no more clients join, the
- session will start 15 minutes later. If another client joins before the
- 15 minutes timeout, the timeout counter will reset to 15 minutes and start
- counting down again.
-
- The auto-start timeout value is indicated on the Windows multicast server
- by entering a value in the Auto-start timeout value box in the main window.
- The value can also be set through the -o command line switch on both the DOS
- and Windows Multicast Server.
- For example
-
- DOSGHSRV c:\test123.gho sessionname -O15
- GHOSTSRV c:\test123.gho sessionname -O15
-
- These examples set the timeout to 15 minutes.
-
- 8) NT Service Pack 4 Network interface fix
- ---------------------------------------
- NT Service Pack 4 introduced changes the way the operating system reports
- network interfaces. Under NT SP4, IP addresses belonging to RAS servers
- appear on the list of network interfaces that Ghostsrv uses to listen
- for connections. These interfaces are unusable for multicasting so
- Ghostsrv will now not try to bind to these interfaces when the "Accept
- Clients" button is pushed.
-
- This change fixes the
-
- 'RML_bind failed, cannot assign requested address'
-
- error that occurs using earlier versions of Ghostsrv with NT service
- Pack 4.
-
- N.B. If you set the logging level to 'Information' or higher,
- you will see exactly which interfaces Ghostsrv has
- encountered problems with.
