Manually Creating a Swapfile on VU+DUO/SOLO

First off, telnet in to the box using your favourite telnet programme.

Then, type the following command (after count, enter the size of file you want. In example below, it is a 128mb swap - 1024 x 128 = 131072):

dd if=/dev/zero of=/media/usb/swapfile bs=1024 count=131072

Then, set up a linux swap area

mkswap /media/usb/swapfile

Now, to activate the swap space immediately, type:

swapon /media/usb/swapfile

Now, activate the swap file to load when the vu duo loads, we need to edit the fstab file. To do this, type the following command to edit the fstab file:

vi /etc/fstab

Add the following line to the file:

/media/usb/swapfile  swap                 swap       defaults              0 0

Now, when the box restarts, the swap file should automatically be enabled...

To verify that it has worked correctly, type the following command in a telnet session:

free

This should give you some information similar to below:

total         used         free       shared      buffers
      Mem:       140848       135964         4884            0          564
     Swap:       131064         1848       129216
    Total:       271912       137812       134100

How To Create Swapfile On ViX image

Menu >> Setup >> ViX >> Swap Manager

Blue/Create >>Green/Activate >> Yellow/Autostart.

Restart the receiver so the Swapfile will become active..

Basically, it gives your system more memory to cache things to, which can be useful for low memory box like the Solo..

If you have lots of processes or plugins installed it may sometimes struggle, this is where the swapfile will help.
