I'm using 2.4;

I just went through a messy way of setting up a swapfile - but I
certainly learned ;-) -- What can I say, but I'm new.
Read all about it here;

(jump to the "SOLVED" altered title for quick answer)
Basically to setup a swapFILE - I did this;
# First - to create the actual file - say of 128MB;
# Note; I used 1024 as a (1K) block size, but you can choose much
# larger, such as 32KB perhaps, if you like. Count=KBYTES
# just do the math and adjust the count= to compensate.
~$ dd if=/dev/zero of=swap bs=1024 count=131072
# Where I chose to place the file. Options explained in 'man mkswap'
~$ mkswap -c -v1 /var/tmp/swap
# Now, turn the swapfile on (notify the kernel);
~$ swapon /var/tmp/swap
# Finish up by editing (create and entry in) /etc/fstab
# so it is kept, found and used upon bootup (I used 'nano'
# as the editor).
# pri= is unnecessary and only used if multiple swaps are present..
# otherwise 'defaults'(?) might be correct/ok there, under options
~$ nano /etc/fstab
# I added this line
/var/tmp/swap swap swap pri=32500 0 0
Can check for usuage;
~$ cat /proc/swaps
Filename Type Size Used
Priority
/var/tmp/swap file 131064 0 32500
Also use 'free'
$ free
total used free shared buffers
[snipped]....
Swap: 131064 0 131064
I *think* I outlined all the steps correctly ,but since I'm very new -
please take that into consideration.
Note also - there are some mitigating reasons why I didn't just create
a swap *partition* (no more partitions are available on this HDD - just
for now)-- though creating a swap partition is even easier and is
discussed in detail in my thread I linked to in c.o.l.misc
