Running this script will create any number of tahoe nodes with an introducer on a single computer where tahoe is set up. Run it quickly like this: wget -q -O - https://raw.github.com/gist/5070115/deployTahoeTestGrid.sh | bash

deployTahoeTestGrid.sh

#!/bin/bash

# Run by doing:
# wget -q -O - https://raw.github.com/gist/5070115/deployTahoeTestGrid.sh | bash

####### Change stuff here:

# somewhere with a little bit of space, with tahoe's defaults you need at least 1GB to upload anything:
directoryWithSpace="$HOME/tahoeTest/"

# your path to tahoe, or if tahoe is in your path, just tahoe=tahoe should work, but I'm working on stuff, so I have the git checkout in my home directory:
tahoe=tahoe
#tahoe="$HOME/tahoe-lafs/bin/tahoe"

N=11 # number of nodes, mine goes up to 11

####### You don't need to change anything below, but check for rm -rf statements.  Never trust me, because I don't trust me.
