How do I enable a user to FTP to a Solaris host?
The ftpusers file, in either /etc/ftpd or /etc contains a list of users who cannot ftp to the host. Simply edit this file and remove root, and your ftp will succeed.

How do I add swap-to-file to a Solaris host?
First you need to create the file that will be used for the OS swapping. I allocate these files in 1GB chunks (rather than larger sizes), so that it's easier to adjust the amount of swap-to-file.

Since the files are huge, the Sys Admin must find a filesystem with at least the amount of free storage required. Let's say they chose the /space filesystem. I name the file so as to suggest the size of the file. "2e30" is a notation that suggests 2 to the 30th, or 1073741824 bytes.

I issue these commands to create the swap file:

# cd /space
# mkdir swap
# cd swap
# mkfile 1073741824 swap0.2e30

If they need more swap space, I'd issue the command with incrementing names, swap1.2e30, swap2.2e30, etc. The command will take some time to complete, because mkfile actually allocates the sectors on disk for the entire size of the file. So the above command created a 1073741824-byte file named /space/swap/swap0.2e30.

Then, you need to tell the OS to use the new swap file:

# swap -a /space/swap/swap0.2e30

Finally, you need to tell the OS to use the swap-to-file each time it reboots. (The above command just added it to the current system; it'd go away when the system rebooted.) To do this, you need to edit /etc/vfstab, and add the following line at the end of the file:

# /space/swap/swap0.2e30 - - swap - no -

(each of the "-" characters is mandatory, separated by spaces.)

Then, to see if everything worked, use this command:

# swap -l

It should display something like this:

swapfile dev swaplo blocks free
/dev/dsk/c1t0d0s1 118,1 16 4194800 2842224
/space/swap/swap.2e30 - 16 2097136 2097136
