FTP Clients of Polymer.chem.cmu.edu

The purpose of this document is to inform our FTP (File Transfer Protocol) clients as to the nature of their accounts with the Matjaszewski lab server, "Polymer.chem.cmu.edu". Our goal with this service is to assign each collaborator of the Matjaszewski lab with an accessible FTP account to enhance our lab's abilities to share information and ideas.

With FTP, files can be distributed in a common format, either ascii or binary depending on what program has created the file. Word documents, Wordperfect documents, Powerpoint figures, JPEG compressed pictures, GIF formatted files, encapsulated postscript (*.eps) files, .... can all be sent via binary mode FTP with no conversion of format. This eliminates the need for email enclosures and provides a central location from which to distribute information.

For Windows 95 users FTP is a command built into the operating system provided the TCP/IP protocol has been installed on the resident computer. Macintosh users should have available to them the MAC/TCP (Open transport 1.x) contol panel for configuration of their internet connection. Software support for FTP on Windows 95 is provided here:

-trial version of WinZip95

-Shareware version of WS-FTP32

(WinZip95 is needed to unpack the WS-FTP Software. Click on WinZip95 to download winzip 6.X onto your local '95 Machine. Run the WinZip95.exe by double clicking the executable's icon or from the Start Menu choose Run and type in the command line window, path/winzip95.exe. This will install winzip 6.x. Use Winzip to extract Ws_FTP32.zip into an empty folder. Follow instructions provided with the WS_FTP32 software to install this Windows friendly software)

Software support for Macintosh users is provided here:

-Shareware version of Fetch 3.0.1

-Fetch 3.0.1's README file
