SunOS 4.0 - Any information which may help us diagnose your problem, Inetd is sensitive to the order of entries in /etc/inetd.conf. In particualar, putting a non-rpc or non-internal type of entry in the file after the rpc or internal entries does not work. If the new entry is after the rpc entries, the portmapper and NFS fail. If it is after the internal entries, then the new entry does not work. We discovered this while trying to implement the 4.3 BSD version of talk. We used this line: ntalk dgram udp wait root /usr/local/etc/in.ntalkd in.ntalkd It must come before the internal and RPC entries in inetd.conf for talk to work at all. This behavior is very non-intuitive, to say the least!

My inetd.conf follows, and it includes three entries after the internal and RPC entries, which all work just fine.. Look for a missing argument to one of the RPC or internal entries preceeding your local entries. # @(#)inetd.conf 1.17 88/02/07 SMI ftp stream tcp nowait root /usr/etc/in.ftpd in.ftpd #telnet stream tcp nowait root /usr/etc/in.telnetd in.telnetd shell stream tcp nowait root /usr/etc/in.rshd in.rshd login stream tcp nowait root /usr/etc/in.rlogind in.rlogind exec stream tcp nowait root /usr/etc/in.rexecd in.rexecd #finger stream tcp nowait root /usr/etc/in.fingerd in.fingerd #tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -s /tftpboot comsat dgram udp wait root /usr/etc/in.comsat in.comsat talk dgram udp wait root /usr/etc/in.talkd in.talkd name dgram udp wait root /usr/etc/in.tnamed in.tnamed daytime stream tcp nowait root internal time stream tcp nowait root internal echo dgram udp wait root internal discard dgram udp wait root internal time dgram udp wait root internal # #@mountd/1 dgram rpc/udp wait root /usr/etc/rpc.mountd rpc.mountd rexd/1 stream rpc/tcp wait root /usr/etc/rpc.rexd rpc.rexd #ypupdated/1 stream rpc/tcp wait root /usr/etc/rpc.ypupdated rpc.ypupdated rquotad/1 dgram rpc/udp wait root /usr/etc/rpc.rquotad rpc.rquotad rstatd/1-3 dgram rpc/udp wait root /usr/etc/rpc.rstatd rpc.rstatd rusersd/1-2 dgram rpc/udp wait root /usr/etc/rpc.rusersd rpc.rusersd sprayd/1 dgram rpc/udp wait root /usr/etc/rpc.sprayd rpc.sprayd walld/1 dgram rpc/udp wait root /usr/etc/rpc.rwalld rpc.rwalld # # TMC additions/changes finger stream tcp nowait nobody /usr/local/etc/fingerd fingerd supdup stream tcp nowait root /usr/local/etc/supdupd supdupd telnet stream tcp nowait root /usr/local/etc/telnetd telnetd -- Bill Nesheim; Thinking Machines Corporation, Cambridge, MA +1 617-876-1111 nesheim@think.com, {ames,bloom-beacon,mit-eddit}!think!nesheim

I think the attached diff of the 4.3bsd and 4.3bsd-tahoe inetd.c may be of
interest. The se_bi flag in the data structure that holds /etc/inetd.conf
was not being reset when a non-internal entry was encountered after an
internal entry. Hence the problem described in
<8903061946.AA20555@emoryu1.cc.emory.edu>
I have no idea how SunOS versions relates to these. We encountered the
problem with a System V implementation derived from bsd (for which a fix
was issued by the TCP supplier well before tahoe was announced).
