Hi, E-buddies: Please accept my apology if my question is put in the wrong group. Recently, I connected an Apollo workstation (BSD DOMAIN/IX) to the local area network (Ethernet) at the University of Oregon. But I got a problem. I cannot rlogin the Apollo workstation. The message (double underlined) I got back is % rlogin apollo rlogind: All network ports in use. ================================== When I tried telnet, it seemed working but I got another painful message as soon as logged on: % telnet apollo Trying... Connected to apollo-gateway. Escape character is '^]'. 4.2 BSD DOMAIN/IX (uo_apollo_1) login: root Password: Welcome to BSD4.2 DOMAIN/IX! B# ls acl_protos patches Connection closed by foreign host. ================================== I thought it might be that the port that the Apollo tried to use is occupied by another host, however, I did not find any. Can anyone tell me what is wrong with it, or give me some hints? Thanks in advance. Wing Wingkuen Chung P. O. Box 3120 | chung@cs.uoregon.edu Eugene, OR 97403 | University of Oregon.

Check under directory /dev. How many "ttyp[0-f]" files do you have? Who are the owners of them? When you rlogin to an Apollo workstation, you take up the first available "ttyp[0-f]" file, and you are assigned to be the owner of that file. After you logout, the owner is changed back to root again. If all of these "ttyp[0-f]" are being used, you can not rlogin or telnet to the system. The solution would be to create more "ttyp[0-f]" files and corresponding "ptyp[0-f]" files with the command "crpty". As for the problem with telnet, I don't know the answer. We have an Apollo DN4000 running BSD4.3 under DOMAIN_OS 10.1. When I use telnet to access the workstation, the computer won't even allow me to login as root directly. But when you telnet, you still need an available "ttyp[0-f]" file to login. ------ Xuyong Liu liu@alpha.ece.jhu.edu ins_bxl@jhunix.uucp

^^^^^ ^^^^^ ^^^^^^^^^^^^^
Root login is controlled by the /etc/ttys file. By default, the console is
the only login port allowed for root. For remote login, you need to add
entries for ptys with the "secure" field on. Look at this file and read
manual descriptions for more details on how to set this up.
