TCP/IP Package for TXS-Plus Submitted by Alan R. Baldwin, Kent State University, Kent, Ohio 44242 Operating System: TSX-Plus(RT-11) Source Langauge: DECUS C and RT-11 Macro Abstract: The 'TCP/IP Package for TSX-Plus' provides TCP/IP networking services for multiple users with TSX-Plus. The package is an assemblage of server and client programs designed to provide Telnet, FTP, Mail, POP3, LPD, and HTTP services for local and remote users of TSX-PLUS systems. The programs are written in C and RT-11 macro. A security system allows usernames/passwords and authorizations for each client/server component to be speci- fied for each user. The sources for the 'TCP/IP Package for TSX-Plus' include header, command, C language, and macro files. The DECUS C com- piler (with some bug fixes) and AS assembler are included with the software distribution to allow the package to be recompiled from the supplied sources. The current implementation uses 8 global regions to support multiple client/server programs simultaneously. The number of regions used by each service is TELNET(1), RTELNT(1), FTP(2), FTPL(2), RFTP(2), MAIL(1), RSMTP(1), RPOP3(1), MMAIL(1), MAILER(1), CNCT(1), RCNCT(1), RHTTP(1), RGOPH(1), NTSND(1), LPQRM(1), and RLPD(1). The hardware requirements are a TSX-PLUS system having a minimum of 512k bytes of memory, a DEQNA/DELQA (Q-Bus) or DEUNA/DELUA (Unibus) ethernet card with associated thick or thin wire adapter, and optionally a pair of dedicated serial lines for each simultaneously active remote Telnet session.
