General Information on Accessing the CELSS-L Fileserver Database

This file contains information and rules for the CELSS-L fileserver. Information, rules and commands for the CELSS-L discussion group are the subject of another document (DGINFO GENINFO). Copies of either of these can be obtained from the list OWNer or from the automatic fileserver.

The CELSS-L was established to serve the members of the NSCORT based at Purdue University. CELSS-L is being run and maintained using LISTSERV. One feature of CELSS-L is the email server, which will be the environment of the discussion groups of CELSS-L. Another aspect of LISTSERV is an email-based fileserver. A database has been established for CELSS-L, the index for which is called CELSS-L FILELIST. Any file (or filelist) can be requested from LISTSERV through normal email messages. The file will automatically be sent to the requester as an email message.

The CELSS-L database is currently under construction. Hopefully in the future, it will be a means for distributing information to several audiences, Purdue NSCORT personnel, other CELSS researchers, sources for extramural funding, and the general public. LISTSERV provides a means by which file access privileges can by defined. File access codes (FAC) will be given for each file in the CELSS-L FILELIST. Currently only three are in use; ALL (general access for the world), PRV (access limited to CELSS-L subscribers), OWN (access limited to the list OWNer). All of the files on the CELSS-L FILELIST are protected against tampering by limiting the PUTting of files to the list OWNer. Various FACs will be used for the GETting of files. No passwords will be required to GET a file.

Files can be requested from LISTSERV using ordinary email messages. These messages should be sent to "LISTSERV@vm.cc.purdue.edu" and do not need a statement on the subject (or RE:) line. The body of the message should only contain the command statements. The command statements generally take the form GET filename filetype. The first file that any new user will need has the filename CELSS-L and the filetype FILELIST. This file contains an index of all of the files available from CELSS-L. To have this file automatically sent to you, send an email message to LISTSERV and have the body of the message as GET CELSS-L FILELIST. The file will be sent to you as a normal email message. Depending on the amount of traffic on the Purdue mainframe, this process can require just a few moments or several hours.

The CELSS-L FILELIST file has set format, with information in columns. The first two columns contain the filename and filetype of an entry. The next two columns contain the FACs for the GET and PUT commands respectively. The FAC in the GET column will tell you whether you have clearance for downloading a particular file. The rest of the information in the FILELIST is for administrative purposes, although there will usually be a short comment about the contents of each file, to aid in your selection process. To GET any of the files listed in the CELSS-L FILELIST one simply sends an email message to LISTSERV, the body of the message having a command statement in the form GET filename filetype.

The files that you GET from the fileserver may not be in a format which is intelligible without some unpacking. In general, files will be uploaded using BinHex4.0 and will need to be downloaded and converted to a normal file for use with the word processing or graphics programs generally found on desktop computers. Many email handling programs automatically convert BinHex files into usable forms. For Mac users, the programs Fetch or Eudora have automatic translators, as do many others. Similar programs are available for PC users. End users who are having difficulty handling and unpacking files downloaded from the CELSS-L fileserver should contact the systems administrator in your area. Do not bring these problems to either the CELSS-L OWNer or the LISTSERV ConTroLler.

It is hoped that the fileserver capability of LISTSERV and establishment of a CELSS-L filelist will help to transfer information within the NSCORT group at Purdue and eventually beyond. If there are suggestions as to how this information document can be improved or suggestions for additional files which may be valuable to park in this fileserver please direct these comments to the list OWNer.
