You installed a new Linux system, but forgot to set enough swap space for your needs. Do you need to repartition and reinstall? No, the swap utilities on Linux allow you to make a real file and use it as swap space.
The trick is to make a file and then tell the swapon program to use it. Here's how to create, for example, a 64 megs swap file on your root partition (of course make sure you have at least 64 megs free):
dd if=/dev/zero of=/swapfile bs=1024 count=65536
This will make a 64 megs (about 67 millions bytes) file on your hard drive. You now need to initialize it: mkswap /swapfile 65536 sync
And you can then add it to your swap pool: swapon /swapfile
With that you have 64 megs of swap added. Don't forget to add the swapon command to your startup files sothe command will be repeated at each reboot.
