2.54.4 Using the Telnet Daemon’s TCP/IP Port

If you are setting up TN server to TCP/IP port number 23, you need to set up the HP-UX computer running TN

server to share this port between TN server and the Telnet daemon program. To do this, take the following steps:

Sharing TCP/IP Port Number 23

1. Ensure that the SNAplus2 software has stopped on the HP-UX computer.

2. Log on to the HP-UX computer as

root.

3. Edit the ﬁle /etc/inetd.conf, and ﬁnd the line beginning with “telnet.”. Make a note of the full pathname

for the Telnet daemon executable program, and any supplied parameters for this program, which are included

at the end of this line; typically these are /etc/telnetd and

telnetd. Insert a

[#] character at the start of the

line to comment out the line, then save the ﬁle.

4. Create an ASCII text ﬁle /etc/snapinetd.conf. This ﬁle should consist of a single line containing the

Telnet daemon executable pathname and parameters, as determined in step 3. For example:

/etc/telnetd telnetd

5. Use the HP-UX ps command to ﬁnd the process ID of the Internet daemon program

inetd.

6. Use the HP-UX kill command to stop this process by issuing the following command:

kill processid

processid is the process ID that you found in step 5.

7. Start the SNAplus2 Internet daemon program by issuing the following command:

snapinetd

8. Restart the Internet daemon program by issuing the following command:

inetd

9. Restart the SNAplus2 software, then restart the node.

Steps 5, 6, 7, and 8 must be repeated each time you restart the HP-UX computer. You may want to set up a shell

script containing these commands, so that it can be run at startup.

Note

If you have set up a session to use the Telnet daemon’s TCP/IP port, do not use SSL for

this session. If you use SSL on a session that uses the Telnet daemon’s TCP/IP port, Telnet

clients will not be able to use

telnet

to access the SNAplus2 computer while the node is

active.

2.55 deﬁne_tn3270_association

The define_tn3270_association command deﬁnes an association between a display LU and a printer LU.

This association allows a TN3270E client to connect to the printer LU that is associated with a display LU without

knowing the name of the printer LU. The define_tn3270_association command can be used to deﬁne a

new association or to overwrite an existing association for a particular display LU.
