the some code from EMULAB to generate and transmit the packet.
No reason to invent something new.
-The remote execution (ssh commands) are all done as "idsl1".
-
Contolling host tools:
-pl-podset: set the host and hash on a remote node
- Call: pl-podset hostIP maskIP targetName
- Uses ssh to call 'pl-podcntl' on the remote node to
- set the host and hash in that node. Also saves the
- information into the file './HashFile'.
-pl-podzap: send ICMP packet to node to resetit
- Call: pl-podzap targetName
- Fetches parameters from the file './HashFile' and
- calls 'pl-poddoit' on the 'hostIP' machine to send the
- reset ICMP packet to the specified target node.
- Note that this relies on the planetlab node that
- was specified in the 'pl-podset' command to actually
- do the packet transmission.
-pl-poddoit: send the ICMP packet (called by 'pl-podzap')
- Routine that constructs an ICMP packet of the proper
- format and send it to the node.
-
-Planetlab node scripts:
-pl-podcntl: set the host and hash into the kernel
- Call: pl-podcntl hostIP maskIP hashValue
- Sets the specified values into the kernel and enables
- the POD filtering operation.
-
-EXAMPLE
--------
-Setting a node to be able to reset (assuming running on 123.123.12.23):
- pl-podset 123.123.12.23 255.255.255.255 planetlab-1.stanford.edu
-
-To later reset the node (command performed on 123.123.12.23):
- pl-podzap planetlab-1.stanford.edu
+pod.py Used to send both ICMP and UDP based POD packets. Requires
+ the hostname to send the packet do, and the configured
+ hash/key for the specified node.
