Tools

Chesapeake created and maintained several java-based network tools. Thanks to a number of people, we've been able to recover the executables for a number of the tools and make them available again.

These tools are also available on the Netcordia Resources web page under the Tools link.

• Access list editor - to help edit access lists.
• Port scanner - to scan TCP ports and report which ones are open on a remote host.
• Subnet calculator - to help you understand how subnetting works.
• ttcp - a tool to test network throughput.
• The Trivial File Transfer Protocol server had a serious security flaw so we've removed it.

Unfortunately, we no longer have the source code for some of the tools. The sources were on a server when the doors were locked and the server was sold at the auction. We don't know what happened to it or the backup tapes.
