Linux add swap space file

To add swap space for Linux, you'll need to add either a swap partition or create a new (big) file and use it for swap:

To add a new 1GB file I do this:

root@debian>
mkdir /swap

dd if=/dev/zero of=/swap/swapfile_1gb bs=1024 count=1048576

mkswap /swap/swapfile_1gb

swapon /swap/swapfile_1gb


To enable the swap file for the next boot, edit /etc/fstab and add this:

/swapfile swap swap defaults 0 0


To check that the swap file is used, type:

swapon -s
free


That's it!

bs: blocksize
count: number of blocks 1 million blocks x 1K = 1G

So you have installed a Debian 5 (Lenny) distro on a virtual machine in VMWare and cygwin on your windows desktop. This is a quick guide (doubles as a reference/reminder for myself) on how to install stuff and get you going.

As stated above I assume this is where you are:
You've downloaded an ISO image from your favourite distro web-site (Ubuntu/Debian).You have installed the distro on a VMWare instance and you gave it a name (e.g. 'debian5')You have a 'root' account and your own named account (e.g. 'username'), advisable to use the same username you use for Windows (helps when accessing your computer from cygwin)
You have cygwin installed on your PC. (I will n…
