The UCSD-CC Server-FTP Facility

1.0 Introduction

The UCSD Computer Center is a service site that must support itself by charging for the usage of its facilities. Because of this, the prospective user of our Server-FTP must supply a valid usercode (USER) and password (PASS) before any further FTP commands are accepted.

Through FTP, you are allowed to access or store files on our disk or on any of our 7 or 9-track tape drives. Each individual file transfer is handled by a separate process on the B6700 and the user is charged for the processor, I/O, core, and (if any) tape charges incurred by this process (note that these charges are quite minimal). Each of these transfer processes is given a separate "job" number and is therefore billed separately for each transfer by our accounting system.

Please note that we have implemented FTP as defined in RFC# 354 (July 8, 1972) except as noted.

2.0 FTP Commands

(1) USER

As mentioned, you must supply a legal, known, UCSD--CC user-code. Following which, the "230" message will be given, asking for the corresponding password.

(2) PASS

After the ’USER’ command is accepted, you must then enter the PASS command giving the corresponding password. If the usercode and password are of correct form, if they match, if there is money in your account, if your account is active, and if you are authorized for "Q1" service, then you will be properly logged-on and the "230" response will be returned.

(3) BYTE

We allow only the (default) byte-size of "8" - all others will be rejected.

(4) MODE

We only allow the (default) mode of "S" (Stream) - all others will be rejected

(5) TYPE

We allow "A" (ASCII) and "I" (Image) types - all others will be rejected. As in standard-FTP, "A" is default.

(6) STRU

We allow both "F" (file) and "R" (Record) structuring. Record- structuring is meaningful only in ASCII/Stream, where CRLF is used as End-of-Line. When using Record-structuring in a STOR to us, if an incoming record is longer than the "MAXRECSIZE" of the designated B6700 file, then we close the data connection, issue a reject message, and abort the local (B6700) transfer process. If a record of incoming data is shorter than the specified MAXRECSIZE of the file, then the record is filled-out with blanks in type- ASCII or with nulls (0) in type-Image. With Image, of course, this applies only to the last record of the B6700 file. As in standard-FTP, "F" is default.

(7) ALLO

We have taken the liberty with the FTP-protocol of using the "ALLO" command to enable the user to designate the B6700 "file- attributes" of his UCSD file. The FTP-standard form of ALLO is ignored (i.e. "ALLO n", where ’n’ is some integer), although a "200" response will be returned in this case. Our "special" form is where the ALLO verb is immediately followed by a "#", which is in turn followed by a paren...
