Mac TCP Watcher reports as many errors as possible so it can be used to test your TCP setup. Mac TCP Watcher can test by sending UDP and TCP echos, and ICMP Ping packets. The echo tests require a nice unix box to support the echo ports, so to get around this, Mac TCP Watcher has a UDP and TCP echo port server, so you can test it to yourself, as well as to other Macs running Mac TCP Watcher. There is a function to test your DNS. Finally Mac TCP Watcher has a Traceroute function which lets you determine the path your TCP packets are taking to a given destination. Note: DNS means Domain Name System, it is the service that converts names (like www.stairways.com) and converts them into IP numbers (like 205.199.66.216), or vice versa (enter 205.199.66.216 and get www.share.com). This documentation describes in some detail tests you can do on your TCP/IP stack. On the Macintosh the two most widely used TCP/IP stacks are MacTCP and Open Transport. Open Transport is the newer and more 'robust' of the two. Throughout this document both MacTCP and Open Transport TCP/IP code is referred to as your 'TCP stack' and your MacTCP control panel or TCP/IP control panel is referred to as your 'TCP control panel'. https://web.archive.org/web/19980213001723/http://www.stairways.com/stairways/mtcpw/mtcpwdocs.html 1/8 12/21/21, 11:00 PM mtcpwdocs.html Using Mac TCP Watcher When you run Mac TCP Watcher, the first window which pops up is the TCP Info window. This contains TCP information and a series of buttons which are tests you can run. Most of the fields are self explanatory, but some additional detail is given in the section below 'The TCP Info window'. All the statistics displayed in the TCP Info window are accumulated since the TCP stack was initialised, not from when Mac TCP Watcher was started. Thus if you quit and start Mac TCP Watcher again, none of the connection or transmission …
