Changing Whatbox plans and/or servers

This assumes that you have bought a new slot while you still have access to your first slot.

  1. SSH into your new server.
  2. Create a new screen that rsync will run in. screen -S rsync
  3. Run this command from the new server. Make sure to replace "oldserver" in the command with your previous server's name. This command is all on one line: rsync -avhSP --stats /home/user/
  4. Enter your old slot's password when it asks.
  5. Detach from the screen and let rsync do its business. Ctrl+A, d
  6. Give it some time. If you'd like to reattach to the rsync screen, simply screen -r rsync

The breakdown of the rsync command is as follows
rsync - Runs the syncing program rsync
a - archive mode; equals -rlptgoD (no -H,-A,-X)
v - increase verbosity
h - output numbers in a human-readable format
S - handle sparse files efficiently
P - same as --partial --progress (keep partially transferred files and show progress during transfer)
--stats - give some file-transfer stats

Before starting the transfer

Shutdown rtorrent on the new slot with pkill -f rtorrent to prevent any torrents from accidentally being added before the transfer is over. Leave the client offline until the data synchronization has completed.

After the transfer is done

You will need to restart your client for it to acknowledge new files and torrents, this can be done by hitting the Restart link on your manage page.

If you're getting 0% complete for all of your torrents, try checking the path where it looks for the files, if it's something like /mnt/sd*1/user/files/, try changing it to /home/user/files/ and rechecking the torrents.

Regularly downloading files with rsync

With a few extras.

Using rsync is by itself pretty straightforward, but you can also get a bit more out of it. Setting this up will download anything new when it is finished, and send you an email listing of what was downloaded since the last email, with usage information from Skynet. Using cron you decide how often it runs, and within the script you decide at what hour you want the mail.


For this to work properly you need to be using rTorrent and passwordless SSH authentication. Add the following line to your rtorrent.rc and create a directory called "finished" in the root of your home directory.

system.method.set_key =,link3,"execute=ln,-s,$d.get_base_path=,/home/user/finished"

This makes a symbolic link in ~/finished when whatever you are downloading is completed.

You will also need ncat (from nmap), and msmtp on your local *nix server. ncat is needed to get info from Skynet, and msmtp needs to be configured separately for mail to work. This guide should be good for that.

The script below should be saved to a .sh file, and use cron to run it as often as you like.

# I believe this cut line is simpler than using awk with print arguments. This series of commands looks for the "+" in the rsync log file and removes everything up to and including the last "+". Then grep filters out the first supposed file in the list which is just "./". After this, sed takes over and strips all the subdirectories from the first "/" encountered after the parent directory name(s). All that's then left to do is to wipe out all the duplicate lines so that all that remains is each parent directory without any duplication and unique files. It essentially creates the same list as what's in the /finished/ folder but at least it's from a confirmed rsync log file rather than working on assumptions, just to keep the script robust.
