This is the homepage for the free “Linux tn5250” emulator.
That’s a bit of a misnomer though, since it works on FreeBSD and any other
modern Unix, and starting with the 0.16.4 release, it also runs on 32-bit
versions of Windows.
tn5250 is a telnet client for the
IBM iSeries and
AS/400 that emulates 5250 terminals and printers. This function is the same as
that provided by the 5250 emulator in
IBM iSeries
Access. Have a look at a
screenshot for an example.
Please report any bugs in tn5250, preferably to the
mailing list, or to the
tn5250
SourceForge bug tracker.
The tn5250 project is kindly hosted by
SourceForge. Visit the
tn5250 SourceForge project
page to see all the other tools they give us to work with.
James Rich has written a useful HOWTO for tn5250.
Read it on his web
site (133kB PDF).
To get the latest stable release of tn5250, visit the
tn5250
project files list.
If you don’t want to have to compile the program yourself,
there are a few other options:
Finally, you can get the latest tn5250 sources from anonymous
CVS, or just browse
them online.
To check out the main branch of tn5250 via anonymous CVS,
enter the following commands. When asked for a password for ‘anonymous’, just
press Enter.
cvs -d:pserver:anonymous@tn5250.cvs.sourceforge.net:/cvsroot/tn5250 login
cvs -z3 -d:pserver:anonymous@tn5250.cvs.sourceforge.net:/cvsroot/tn5250 co -P tn5250
To build the Unix version of tn5250 from CVS, you’ll need
automake, autoconf, libtool and ncurses. Run ./autogen.sh,
./configure then make && make install from the checked out
directory.
To build the Windows version of tn5250 from CVS, you’ll need a
CVS client (maybe WinCVS or
TortoiseCVS). Once you’ve downloaded
the sources, detailed build instructions can be found in the README.txt file in
the win32 subdirectory.
tn5250 development and discussion all happens on the mailing
list, provided by MIDRANGE dot COM. You
must subscribe to the mailing before you will be able to send email to
it, but it’s very low traffic.
There’s a page of
links to related
documentation on this site.
tn5250j
is a 5250 emulator written in Java.
x3270
implements the tn3270 protocol, which is very similar to tn5250.
Source Forge Information
http://tn5250.sourceforge.net/
Note: You should know the name or Internet address of the remote system with
which you want to start the Telnet session. To display the Internet addresses
and host names, complete the following steps:
Start iSeries Navigator and expand your iSeries server --> Network.
Right-click TCP/IP Configuration and click Host Table to display the Internet
addresses and host names.
Starting a Telnet client session
Type the STRTCPTELN command, or type TELNET at the iSeries command line and
press Enter.
Type the name of the remote system, if you want to use optional parameters,
press F10. Otherwise, press Enter.
If you typed *INTNETADR for the Remote system field, the server prompts you for
the Internet address field.
Type the Internet address of the remote system, if you want to use optional
parameters, press F10. Otherwise, press Enter. The display shows optional
parameter values and the Internet address information.
To use the default parameter values, press Enter.
When starting a 5250 full-screen mode session, the following optional parameters
are also applicable:
Timeout wait for host (INZWAIT)
Keyboard language type (KBDTYPE)
Port number of the remote host server application (PORT)
Remote Virtual Display (RMTVRTDSP)
Remote User (RMTUSER)
Remote password (RMTPWD)
Remote paswword encryption (RMTPWDENC)
Remote initial program (RMTINLPGM)
Remote initial menu (RMTINLMNU)
Remote Current library (RMTCURLIB)
Remote Keyboard Type (RMTKBDTYPE)
Remote character set (RMTCHRSET)
Remote code page (RMTCODPAG)
The next display is the sign-on display for the remote system.
Notes:
The signon panel will be displayed only if none of the Autosignon parameters are
entered on the STRTCPTELN command (RMTUSER, RMTPWD, RMTPWDENC) or if there was
an error when these parameters were entered. If these values are entered
correctly, no signon panel will display. The user is automatically signed on,
and whatever initial screen defined for the user will display.
In addition the following is also true:
If the STRTCPTELN command provides the correct RMTUSER, RMTPWD and RMTPWDENC
parameters, and a correct RMTINLPGM parameter is also provided, then the user
will be signed on. Also, the provided initial program will have run.
However, if an invalid RMTINLPGM is provided, the user will be signed on, but a
'job ended abnormally' message will display. The same actions are true for
RMTINLMNU parameter.
For the RMTCURLIB parameter, a correct value will result in the user being
signed on. Also, any initial program and/or menu as defined either in the users
profile or on the STRTCPTELN command, will execute. In addition the current
library will be set to the parameter value. If in invalid RMTCURLIB parameter
value is provided, then a signon panel will be displayed with a message stating
that the current library value is invalid.
Also, for all of the above items, if the RMTKBDTYPE and/or RMTCHRSET and/or
RMTCODPAG parameters are provided with valid values, they will have taken effect
for the successful automatic signon attempts. They will not have taken effect
for the invalid signon attempts.
Note: If the system does not find or configure a SOCKS server, or if errors
occur using the SOCKS server, then a direct connection is established.
TN5250 screen size
Telnet 5250 full-screen mode supports the following screen sizes:
