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.
