First of all, this is absolutely _not_ the right forum for a UNIX System
Services question. This mailing list is for Linux on S/390 and zSeries.
Having said that, your problem is has two parts to it. If you want to have
port 23 to allow telnet to USS, then remove it from TCPIP.TCPPARMS(PROFILE).
Next, update /etc/services to read:
otelnet 23/tcp
login 513/tcp
instead of what you have. The service name being defined and referenced is
"otelnet," not "telnet." (Don't blame me, IBM decided to get too cute on
that whole "o" naming scheme.)
If you want port 2023 to be for TN3270 access to OS/390, then you should
also have some TELNETPARMS defined. Here's what one of my systems has:
TELNETPARMS
PORT 2023
INACTIVE 600
TIMEMARK 600
SCANINTERVAL 120
SMFINIT 1
SMFTERM 1
WLMCLUSTERNAME TN3270E ENDWLMCLUSTERNAME
;
; **** The following two new parms are introduced by PTF UQ35837
MAXRECEIVE 65535 ; This is the maximum receive without an EOR
; for a client to send in.
MAXVTAMSENDQ 50 ; This is the maximum number of RU's that are
; allowed to be queued up for VTAM
ENDTELNETPARMS
Make sure you have your OS/390 TCP/IP STC running. You can check this with
the "NETSTAT" TSO command and see if port 2023 is being "listened" on by
TCP/IP.

Subject: UNIX System Services otelnetd and message "Resource temporarily
unavailable".
I don't know if this is the right place to ask this but please help me I'm
going nuts!
In USS (OS/390 2.9) I configured rlogin and it is working fine, but when I
finished customizing telnet (the tiny thing that comes in the manuals about
otelnetd) nothing works.
After OMVS initialization I get these messages:
$HASP373 BPXAS STARTED
BPXF024I (OMVSKERN) Feb 15 16:10:47 inetd 6 : FOMN0026 otelnet/tcp: 39
unknown service
BPXF024I (OMVSKERN) Feb 15 16:10:47 inetd 6 : FOMN0027 login/tcp: 394
socket: EDC5112I Resource temporarily unavailable., rsn=112B00B6
And I haven't been able to find messages FOMN0026 and FOMN0027 anywhere.
Here's how the ports are defined, In OS/390 TCPIP.TCPPARMS(PROFILE):
23 TCP INTCLIEN ; Telnet Server
2023 TCP INTCLIEN ; TELNET SERVER ALSO SEE PORT 23
And in OMVS /etc/services:
telnet 23/tcp
login 513/tcp
In the /etc/inetd.conf file:
otelnet stream tcp nowait OMVSKERN /usr/sbin/otelnetd otelnetd -l -D all
login stream tcp nowait OMVSKERN /usr/sbin/rlogind rlogind ?m
When I do a telnet to the address of the OS/390 with port 2023 I get the
message: Could not open a connection to?
Any hints on this?
