Hello, could somebody explain the difference between the version of NCSA Telnet that requires MacTCP and the one that doesn't? Does the one that uses MacTCP enable one to do more? I have MacTCP but don't have a very good idea of what it's doing. Thanks for your help. Keith Conover ireland@ac.dal.ca

Using it for your applications will allow you to avoid duplicating entries such as IP#, gateway IP#, netmask, etc. for each application. It will also aid you in getting multiple TCP/IP applications to run together. If every application had its own implementation of the TCP/IP stack there would be very little hope that you could get them to cooperate with regards to access to the network interface. >Thanks for your help. >Keith Conover >ireland@ac.dal.ca -- Greg German (german@sonne.CSO.UIUC.EDU) (217-333-8293) US Mail: Univ of Illinois, CSO, 1304 W Springfield Ave, Urbana, IL 61801 Office: 129 Digital Computer Lab., Network Design Office

In order to participate on a TCP/IP network, you need software that understands TCP/IP. In the bad old days, this software was built into applications. That meant that only ONE such application could do TCP/IP at a time. NCSA Telnet was such an application (and still is, in the non-MacTCP version). You run NCSA Telnet, and nothing else that uses TCP/IP. MacTCP is Apple's TCP/IP software, and it's written as a driver, meaning that multiple applications can access it. So, you can have the MacTCP version of NCSA Telnet, and the HyperCard FTP stack, and a news reader, and a mail program, and whatever other stuff you want, all going at the same time. If the only TCP/IP app you use is NCSA Telnet, it probably doesn't matter much which one you use. If you ever intend to use other TCP/IP services, use the MacTCP version. -- Steve Dorner, U of Illinois Computing Services Office Internet: s-dorner@uiuc.edu UUCP: uunet!uiucuxc!uiuc.edu!s-dorner
