I’m really puzzled as to where to go from here. It seems they are UDP packets with a destination port of 22102. Investigating further I captured the packets sent whilst connecting with WinVV. The forum ‘BizTalk 2004 BizTalk 2010’ is closed to new topics. It’s just that no other emulators seem to work, hence my guessing about the problem being winvv using UDP and the others use TCP. This seems really odd because I thought that anything that connected to a (telnet?) session needed to use telnet. I’ve had a read on the site and I don’t think its anything to do with the connection lag since the WinVV 3270 emulator connects immediately. To investigate this I tried a simple telnet to the HIS server, expecting an error back stating it couldn’t understand 3270 streams, but the telnet connection simply times out. I’d like to use an open source telnet client rather than the WinVV one, and my problem is that they don’t seem to work. When we connect in with a terminal emulator called WinVV (closed source developed back in the day by British Rail) we get a session that was specified inside the WinVV config and hey presto it talks to the 3270 mainframe. We have an HIS that has some (telnet?) sessions on it. All rights reserved.I’m not entirely sure I understand the problem we’re experiencing at the moment but I’ve hit a brick wall and really have no idea where to go from here. Set tcpip keepalive_active=on keepalive_idle=00:04:30 keepalive_byte=off This seems really odd because I thought that anything that connected to a (telnet) session needed to use telnet. # set Wide-Area-Network friendly TCP Keepalive settings

Once you start the server, establish the connection with the client: nc -u localhost 2399. As you can see, the command establishes the UDP connection just requires the -u to be added to the command: nc -u -l 2399. Print "Attempting to send file to IP:%s" % (cpxcfg,cpxip) From the server side, run the command below.

Password = settings.get("password","dbps")Ĭpxcfg = settings.get("cpxfile","config.txt") Username = settings.get("username","root") # use telnet to send text lines down to a Digi Product This routine sends all text lines in a file named 'config.txt' to a Digi device: # However, you can also use Python and Telnet to do the same thing. Use ncat again to send messages to the udp server and the udp server replies back.

One option is to use the Web UI's Backup/Restore to copy configurations from 1 unit known to be setup correctly to the other 199. In this article we are going to see how to use UDP sockets in python.

Chain INPUT (policy DROP 0 packets, 0 bytes) target prot opt in out source destination. do you need to log into the Web UI 200 times and try to remember to set all of the correct changes? Of course not. When Telnet is Disabled (which is also the default on modern versions of the sensor software), the sensors firewall configuration includes a rule for dropping Telnet traffic: -bash-2.05b iptables -L INPUT -nv.
