Hello, I have inherited an Explorer II from someone on campus, and I am trying to connect the machine to the network. I believe that the physical connections are OK, and that I have set up the namespace correctly with the relevant IP addresses set. The problem is, when I try to connect to another machine on the net using telnet or the VT100 emulator, I get the following message: "No service was able to handle the CONNECT LOGIN operation." Can anyone out there give me any clues as to what might be wrong or where to proceed next? Thanks in advance...Michael Tanenblatt (tanenbla@cs.columbia.edu mat1@cunixd.cc.columbia.edu)

This is because the TI networking software is more than a little bit silly. Even if a host supports a protocol, the Explorer won't even *try* to connect to that host unless you have advertised that connect-option in the namespace. Explorers should have these :SERVICES attributes: ((:STATUS :CHAOS :CHAOS-STATUS) (:STATUS :TCP :IP-STATUS) (:MAIL-TO-USER :CHAOS-STREAM :MAIL) (:MAIL-TO-USER :TCP-STREAM :SMTP) (:LOGIN :CHAOS-STREAM :TELNET) (:LOGIN :TCP-STREAM :TELNET) (:FILE :LOCAL :LOCAL-FILE) (:FILE :CHAOS :QFILE) (:FILE :TCP :FTP) (:TIME :CHAOS-SIMPLE :TIME-SIMPLE) (:TIME :UDP :TIME-SIMPLE-MSB) (:UPTIME :CHAOS-SIMPLE :UPTIME-SIMPLE) (:SHOW-USERS :CHAOS-STREAM :NAME) (:SHOW-USERS :TCP-STREAM :ASCII-NAME) (:LISPM-FINGER :CHAOS-SIMPLE :LISPM-FINGER) (:LISPM-FINGER :UDP :LISPM-FINGER) ) Unix boxes should have these :SERVICES attributes: ((:STATUS :TCP :IP-STATUS) (:MAIL-TO-USER :TCP-STREAM :SMTP) (:LOGIN :TCP-STREAM :TELNET) (:FILE :TCP :FTP) (:FILE :LOCAL :LOCAL-FILE) (:TIME :UDP :TIME-SIMPLE-MSB) (:SHOW-USERS :TCP-STREAM :ASCII-NAME) ) Another bogosity that you may have to deal with is, if you have an Explorer in your namespace which is on a different subnet, that Explorer cannot have a Chaos address listed. Chaos packets don't make it through network gateways, and (apparently) the only way to convince an Explorer that another Explorer must always be accessed via TCP is to delete the Chaos address. -- Jamie
