For development it may be useful to be able to replay TCP traffic (e.g. HTTP). The dump can be created using WireShark or tcpdump:
$ tcpdump -s 0 port http -i en0 -w dump.pcap

To generate data files that can be replayed through netcat we use tcptrace:
$ tcptrace -e input.pcapng

Finally replay the HTTP traffic using netcat to host 192.168.1.1 port 80
$ cat a2b_contents.dat | nc -v 192.168.1.1 80

If you need to replay the raw network traffic, we need to do some massaging using tcpprep and tcprewrite before using tcpreplay to replay the raw packages. Note that due to limitation of tcprewrite this will not replay any traffic to the network: http://tcpreplay.synfin.net/wiki/FAQ#Doestcpreplaysupportsendingtraffictoaserver.

Transient compute clustering with GNU Parallel and sshfs:

GNU Parallel is a multipurpose program for running shell commands in parallel, which can often be used to replace shell script loops,find -exec, and find | xargs. It provides the --sshlogin and --sshloginfile options to farm out jobs to multiple hosts, as well as options for sending and retrieving static resources and and per-job input and output files.

For any particular task, however, keeping track of which files need to pushed to and retrieved from the remote hosts is somewhat of a hassle. Furthermore, cancelled or failed runs can leave garbage on the remote hosts, and if input and output files are large, sending them to local disk on the remote hosts is somewhat inefficient.

In a traditional cluster, this problem would be solved by giving all nodes access to a shared filesystem, usually with NFS or something more exotic. However, NFS doesn't wo
