Why should I have a swap file.
Question.
Why should I have a Swap File?
Answer.
A swap file of say 32mb behaves like extra memory called upon only when required.
With the latest images, there are times when available memory is insufficient and if there is no Swap File to supply the extra memory, it would then reboot itself due to insufficient resorces.
It is strongly recommended that a swap file is installed on a SD card.
A swap File can be incorporated when you install ijBoot on your system.
If you wish to run only a Flash Image, you still can use the jiBoot facility to set up the Swap File.
How to set up a swap file on SD card.
Question.
How to set up a Swap File on my SD card?
Answer.
Insert a Fat or Fat32 formatted 1 or 2gb SD Card into the mmc card slot in your TM9100 STB.
Switch ON your TM9100 (This must be basically setup including the Communications to the PC),and let it Boot Up.
On your PC, start up the jiBoot facility.
On the PC Screen, select "Check iBoot media mount"
On the Pop-Up screen, check that the radio buttons within the media area has /mmc selected.
On that screen, select "Check iBoot media mount". If the SD Card is recognised, then that patch will go Green.
Exit that Screen, and select "Install iBoot on box".
On the Pop-UP screen, select the "Yes" radio button within the "format Media" area.
Select install iBoot, and when completed the patch will go green.
In the Swap Files area, tick the /mmc box, and then select 32mb in the drop-down box.
Select "Apply new swap params."
The execution log will indicate the swap file list is done and the "Apply new swap params." Patch will disappear from the setup menu.
You now will have a 32mb Swap File on your SD Card.
The file "extra_run" for Flash has also been placed in your /var/bin folder ensuring the swap file starts up at every Reboot
What is CVS.
Question.
What is CVS?
Answer.
In the field of software development, the Concurrent Versions System (CVS), also known as the Concurrent Versioning System, provides a version control system based on open-source code. Version control system software keeps track of all work and all changes in a set of files, and allows several developers (potentially widely separated in space and/or time) to collaborate. Dick Grune developed CVS in the 1980s. CVS has become popular in the open source software world and is released under the GNU General Public License.
What is CIFS.
What is CIFS?
CIFS is a network filesystem plus a set of auxiliary services supported by a bunch of underlying protocols. Any and all of these various bits have been called CIFS, which leaves us with a somewhat muddy definition. To make things easier, we'll start by saying that CIFS is "Microsoft's way of doing network file sharing", and work out the details as we go on.
The name "CIFS", of course, is an acronym. It stands for Common Internet File System, a title which deserves a bit of dissection:
Common
The term has a variety of connotations, but we will assume that Microsoft was thinking of common in the sense of commonly available or commonly used. All MS operating systems have had some form of CIFS networking available or built in, and there are implementations of CIFS for most major non-MS operating systems as well.
Unfortunately, there is not yet a specification for CIFS that is complete, correct, authoritative, and freely available. Microsoft defines CIFS by their implementations and, as we shall see, their attempts at documenting the complete suite have been somewhat random. This has an adverse impact on the commonality of the system.
Internet
At the time that the "CIFS" name was coined many people felt that Microsoft was late to the table regarding the exploitation of the Internet. As will be described further on, the naming scheme they used back then (based on a piece of older LAN technology known as NetBIOS) doesn't scale to large networks--certainly not the Internet. The idea that CIFS would become an Internet standard probably came out of the work that was being done to redesign Microsoft's networking products for Windows NT5 (now known as Windows2000 or W2K). Under W2K, CIFS can use the Domain Name System (DNS) for name resolution.
File System
CIFS allows the sharing of directories, files, printers, and other cool computer stuff across a network. That's the filesystem part. To make use of these shared resources you need to be able to find & identify them, and you also need to control access so that unauthorized folk won't fiddle where they shouldn't. This means that there is a hefty amount of administrivia to be managed, so CIFS file sharing comes surrounded by an entourage. There are protocols for service announcement, naming, authentication, and authorization. These are separate, but intertwined. Some are based on published standards, others are not, and most have changed over the years.
