Capture Replay Your Application Realism

• Inject custom Realism into your testing with
  Application Level Playback
• Integrate custom and proprietary traffic at high
  loads
• Support for UDP and TCP sessions (fully stateful)
• Preserve network timing
• Application data preservation
• Plays through proxy devices
• Control load using all available load specs
• Real-world protocol mix including DDOS traffic

Capture Replay Topics

• Replaying your own pcaps
• Protocol Playback Library
• TCP only options
• Converting pcap to manual commands

Capture Replay 4 easy steps

• Capture live traffic from network
• Import pcap into Commander
• Automatically discover sessions
• Filter on specific sessions
• Configure client and server Profiles tabs
• Include pcap traffic in the Actions list

1. Capture Live Traffic

• Within Wireshark/Ethereal make sure to save pcap
  with the File Type of libpcap
• To reduce the size of the file filter the pcap to
  only the desired session and save the Displayed
  packets only

2. Import PCAP Into Commander

• Click on Content Files tab and green Add button
  to import pcap

• Choose TCP or UDP
• Create Profile name
• Upload Capture File
• Discover Session Automatically
• File name must match name of file uploaded in
  Content Files tab

• Server
• Create Profile name
• Choose CapReTCP or CapRepUDP
• Change port number to that of protocol being
  replayed (see Dest. Port in pcap)
• Upload Capture File
• Discover Session Automatically
• File name must match name of file uploaded in

4. Include In Actions List

• Be sure to add the port number after the IP
  address
• This should match your Server?Profile port as
  well as the destination port in the pcap file)
• The PROFILE name should equal the name of the
  Client?Profiles?Cap Replay profile name from step

• Current Protocols
• Bittorrent
• Citrix
• GTalk
• LDAP
• Napster
• NFS
• SAP
• Socks
• SQLNet
• TFTP
• XWin
• PCAPs converted to Manual Commands within test

TCP Only Converting to Manual Commands

• TCP Only Options (see TCP_Only.spf on CD)
• Client close FIN
• Client close RST
• Server close FIN
• Server close RST
• TCP open connections
• Converting PCAP to Manual Commands
• Allows you to insert delays in packet flow in
  order to keep the connections open longer and
  ramp up the number of open connections
• Allows you to add, delete, or modify the
