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.

AWS Glacier: Delete vault

Follow these steps to remove all archives from an AWS vault. After this is finished, you will be able to delete the vault itself through the browser console.

Step 1 / Retrive inventory

This will create a job that collects required information about the vault.

$ aws glacier initiate-job --job-parameters '{"Type": "inventory-retrieval"}' --account-id YOUR_ACCOUNT_ID --region YOUR_REGION --vault-name YOUR_VAULT_NAME
