ctorrent -C $CACHE_SIZE -B $MAX_KB -M $MAX_CON -e $SEED_TIME "$TORRENTFILE"

My ctorrent was getting killed because it was hogging all the memory. Solution: add swap. http://www.nslu2-linux.org/wiki/HowTo/AddAdditionalSwapSpace

Using ipkg to install CTorrent:

(:table border=0 width=100% bgcolor=#eeffee:) (:cell:)

 
ipkg install ctorrent

(:tableend:)

If you are behind a firewall, you need to open at least port 2706 TCP incoming. CTorrent starts trying port 2706, and if it fails it starts counting downwards towards 2106 TCP.

You might want to install screen (ipkg install screen), so that you can run ctorrent in a screen session:

How to install CTorrent on OpenSlug:

1. ipkg install ctorrent
2. If you are behind a firewall, you need to open at least port 2706 TCP incoming. CTorrent starts trying port 2706, and if it fails it starts counting downwards towards 2106 TCP.

screen -dmS torrent ctorrent <torrentfile>

CTorrent uses quite a bit of memory (Currently, it's using about 58% on my slug), so you might run into problems if you run a lot of services on your slug.

The memory usage is adjustable with -C. The default cache size is 16MB, which explains the high mem usage. In the script below, it's changed to 4MB which is no problem for most slugs. Feel free to change it ;-)

This script is run as a cron-job every now and then.

It doesn't handle filenames with spaces/special chars. You'll need mailx and ssmtp for it to be able to send mail

Below is the script I use to automatically download torrents I save on a share: This script is run as a cron-job every now and then.
I start it as a screen session with "*/2 * * * * screen -dmS torrent /path/to/script" It's not advanced, and doesn't check much for errors. Feel free to update it a bit ;-) And, it doesn't handle filenames with spaces/special chars. You'll need mailx and ssmtp for it to be able to send mail

How to install ctorrent on OpenSlug:

This is rather easy when you know how:

1. $ ipkg install ctorrent
2. $ echo 3 > /proc/cpu/alignment (This needs to be done on every boot, otherwise ctorrent won't download anything)
3. If you are behind a firewall, you need to open *atleast* port 2706 TCP incoming. ctorrent starts trying port 2706, and if it fails it starts counting downwards towards 2106 TCP.

You might want to install screen (ipkg install screen), so that you can run ctorrent in a screen session:
screen -dmS torrent ctorrent <torrentfile>

NOTE: ctorrent uses quite a bit of memory (Currently, it's using about 58% on my slug), so you might run into problems if you run a lot of services on your slug.
