Little trick: with Ctrl + Right click over the tn5250 window, you can access to the “ VT Fonts” menu, and with Ctrl + Left click you can access to the “ Main Options” menu. I put this string in a new menu entries, using the icon from the file /usr/share/pixmaps/tn5250-48×48.png Ok, with this parameters, my launch string became:

font_132: the font used when terminal is in 132 column mode.

The TN5250 protocol allows this communication via a TCP/IP. font_80: the font used when terminal is in 80 column mode TN5250 is a protocol that provides remote terminal access to an IBM AS/400 and iSeries computers.For a list of all terminal models, run the same command of above, man tn5250rc, and search for Display Types section

env.TERM: Set the terminal model name for the emulation session to use.

env.DEVNAME: set the device name for the AS/400 to assign to the 5250 session.

For a list of all translation maps, run this command: man tn5250rc and search for the Translation Maps section

In my case, i use an italian translation map, corresponding to the code 280. Map: set the translation table between ASCII and EBCDIC. TN5250 Work In Progress Page Developer's Work in Progress Page. However, if you know the TCP port used (see above), you can filter on that one.Ĭapture only the TN5250 traffic over the default port (23): tcp port 23 External linksĥ494 Remote Control Unit - Functions Reference Release 3.0 Document Number SC30-3533-04 You cannot directly filter TN5250 protocols while capturing.

Your capture needs to include the start of the telnet session - this is where the TN5250 protocol is negotiated.

Show only the Telnet traffic (including TN5250 traffic, if present): telnet If the telnet data stream contains TN5250 data telnet will display it automatically. TN5250 is a stream protocol within telnet.

SampleCaptures/Ī complete list of TN5250 display filter fields can be found in the display filter reference.

There are no preference settings associated with TN5250. However it is still a work in progress and has not been submitted for inclusion in wireshark yet. The TN5250 dissector is almost fully functional. The well known TCP port for TN5250/TELNET traffic is 23.

TELNET: Typically, TN5250 uses TCP and TELNET as its transport protocol.

Today, it is more common to use PC or web-based terminal emulation packages that can interpret and display 5250 data streams." Wikipedia Protocol dependencies

Robustly constructed, 5250 terminals weighed roughly 36kg (80 lbs.) The 5250 terminals generated an audible clicking sound as the user typed, similar to the electric typewriters of the era. The term "5250" now refers to the content of the data stream itself few physical 5250 terminals (with their bulky Twinax cables) still exist, although they are still used to provide a "connection of last resort," hard-wired to the host computer. NAME tn5250 - an implementation of the 5250 telnet protocol SYNOPSIS tn5250 OPTIONS HOSTNAME xt5250 OPTIONS HOSTNAME tn5250 -version DESCRIPTION tn5250 emulates IBMs 5250 compatible terminals to connect over TCP/IP to an IBM AS/400. The 5250 data stream definition has been refined over time to include GUI elements like pop-up windowing, check and option boxes, mouse handling, and pull-down menus. Extra TN5250 connectivity supports the complete range of terminal types on single or multiple hosts.

Extra supports TCP/IP software of major network vendors who support the Windows Sockets (WinSock) 1.1 specification. The relationship between the terminal and system was rich: The system sent a data stream containing markup bytes indicating the boundaries of data entry fields, highlighted or colored areas, and indication that the system was busy responding to the last request from the terminal. Using Extra you can communicate with an AS/400 via a TCP/IP protocol. Similar to the IBM 5250, it is a block-oriented terminal protocol, yet is incompatible with the 5250 standard. It also connected to the later System/36, System/38 and AS/400 systems. "IBM 5250 was originally a family of terminal devices sold with the IBM System/3, System/32 and System/34 minicomputer systems.
