== Retrieving Log Files From PlanetLab Nodes ==

To retrieve log files from your experiments use the command below:

<pre>
pssh -h nodes.txt -l slice_name -t 300 -p 50 -o ~/results/ "cat yourlogfile.txt"
</pre>

The outputs will be saved to a "results" folder under your home dir. There will be one file for each host/node.

== Copying Large Files From PlanetLab ==

Occasionally, your log file will be too big for pssh. The cat command above will either timeout or cause an out of memory error. Use the script below as an example to copy the files one-by-one using standard scp.

<pre>
#!/bin/bash

for i in `cat ~/nodes.txt`
do
echo "copying from $i"
scp -i ~/.ssh/id_rsa slice_name@$i:~/logfile.txt .
done
</pre>

Don't forget to replace ''slice_name'' with your own slice.

Deploying to PlanetLab

== Deploying Files to PlanetLab Nodes ==

To deploy your app to PlanetLab use the command below:

<pre>
pscp -h ''nodes.txt'' -l slice_name -t 180 -p 200 yourapp.tar /home/slice_name/yourapp.tar
</pre>

Replace ''slice_name'' and ''yourapp.tar'' with the appropriate values.

The '''-t''' switch denotes the timeout period for each node. For example, ''-t 180'' sets the pscp command timeout period to 3 minutes. A "Timeout" status will be returned if the node failed to response within the timeout period.

The '''-p 200''' denotes the max number of parallel threads for the pscp process. A value of 200 means the process will attempt to copy the file to 200 nodes concurrently. Please do not abuse this setting. You will run out of memory if you spawn too many threads.

== Executing Remote Commands ==

You can use '''pssh''' to issue a command to all nodes in your slice. For example, the command below will untar yourapp.tar from the above example.

<pre>
pssh -h nodes.txt -l sfu_games -t 180 -p 200 -o /tmp "tar xvf yourapp.tar"
</pre>

== Installing Java ==

Below is a series of commands used to deploy Java on PlanetLab.

The content of install_jvm.sh

<pre>
#!/bin/sh
echo -e "q\nyes\n" | sudo sh jre-linux.bin | grep "\.\.\."
</pre>

Commands

<pre>
pssh -h nodes.txt -l sfu_games -p 200 -t 600 -o /tmp/test1 "wget -nc http://nsl.cs.sfu.ca/tmp/jre-linux.bin"
pscp -h nodes.txt -l sfu_games -t 180 -p 200 install_jvm.sh /home/sfu_games/install_jvm.sh
pssh -h nodes.txt -l sfu_games -p 200 -o /tmp chmod 755 /home/sfu_games/install_jvm.sh
pssh -h nodes.txt -l sfu_games -p 200 -t 300 -o /tmp ./install_jvm.sh
