[07] WHY CAN'T I USE FTP TO TRANSFER MY FILES? Inbound FTP connections (via FTP, scp or sftp) are available to validated members and above. For more information about validation please type 'validate' at the shell. A slower, but still acceptable method of sending/receiving files from SDF can be found with the XYZMODEM tools. Infact, SDF used XYZMODEM for file transfers before we installed FTP. If you don't know about XYZMODEM, these are a protocol set for transfering files over a dialup modem connection. Some TELNET programs such as TERATERM support these protocols. Examples -------- Uploading a file to SDF: 1. Tell SDF you want to send a file: $ rz (or 'upload') 2. Start the file transfer from your TERMINAL. Downloading a file from SDF: 1. Tell SDF which files you want to download: $ sz filename Usually (with ZMODEM) your TERMINAL will automatically respond by initiating a file transfer session. We recommend using ZMODEM as it seems to be the fastest and most reliable method. You can use "sb/rb - YMODEM or sx/rb - XMODEM" if ZMODEM doesn't seem to work for you. Finally, you can also use the C port of Columbia's KERMIT protocol. This program was original developed to transfer files between the DECSystem-10 and the IBM PCs that students and faculty were using as terminals. C KERMIT actually has a C implementation of CMND-JSYS, the command parser which implementions command completion and recognition that made TOPS-10 and TOPS-20 so popular. Also, there is support for ZMODEM/XMODEM/YMODEM in KERMIT. Use 'set proto zmodem' to turn it on. // Last revision: b548247b82e9c14f6132fc56a430bf34 // [[basics|back]]
