[HECnet] Effects of Rogue Duplicate HECnet Node?

Tops-20 will allow multiple accounts for a user and this was used at a number of university sites that I knew of (but not all).? It had a certain amount of flexibility that I have not often seen. The university had a small commercial programming department (of one or two programmers), yet a number of clients.? If you had to do some work for one client, then you would switch your account to that client's with a "SET ACCOUNT" command along with a remark as to why you did that.? On occasion, a systems programmer or user services consultant could be drafted to do some development and we would switch from university overhead accounts (systems programming was I-X-CU-SY) to whatever the client was and switch back when done. No login or logout was necessary to do this.? Under normal conditions, you could not use an account to which you were not authorized.? Account usage was strictly enforced and also formed one basis for the class scheduler, determining what share of the processor you could hope for. The default account (if one is wanted) can be stored in the Tops-20 login directory (I don't recall whether it is in the FDB or not).? This means that you can connect (via TELNET, FTP and FAL) without having to type an account anywhere. /However/, if no default is specified in the login directory, then you MUST give it or you won't be able to get any service.? The FAL and FTP server ANONYMOUS code will allow account specification.? I guess I put it in out of habit... With the exception of IBM z/OS (n?e MVS/TSO), I am unaware of any operating system that has that degree of granularity of accounting.? Job cards for accounting still exist in JCL, but I don't remember how this was handled in TSO. I would assume that VMS could provide similar services, but I never administered a installation.? I can't remember how (or if) we did accounting on Ultrix, either.? I think we did. On 3/5/20 1:39 PM, Johnny Billquist wrote:
