Can tn5250 emulator be supported by birp ?

I am a developer for the ArchAssault project, we would like to add this to our repo but I noticed its missing a license. Can you please add a license and add a tag as well?

It looks like with py3270 using the lastest git src.

Hi!

during my last activity on mainframe Birp crashed several times with this Exception in different CICS pages:

Traceback (most recent call last):

    raise CommandError(msg.decode('ascii'))
py3270.CommandError: Wait: Timed out

I think it may be an issue related with non-ascii characters, but I'm not sure.

The problem is that when this exception arise Birp and X3270 terminal crash, losing all non-saved data.

Thank you a lot for your great work!

error while compiling the patched binary x3270

Greetings! I love the work you have done with birp. I have been toting around a jumble of half-polished Ruby scripts to accomplish similar things, but I'm very impressed with what you already have working in birp.

One thing I've run into is that sometimes I get errors and crashes from unrecognized characters as birp is translating from x3270 into Python, etc. For example:

Hitting Enter, any of the PF/PA keys, or Ctrl-u will record a transaction.

    return codecs.utf_16_decode(input, errors, True)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2219' in position 24: ordinal not in ran

So far, I am working around this with the following small change:

$ git diff

The same occurs when I save a screen as a transaction, and I'm not sure that just ignoring character transcription errors is the "right thing to do".

Have you run into this in your testing?

Thanks!

Hello,

I have stumbled upon the Birp recently, and it looks promising, probably could be really helpful in the pentest I am struggling now. However I tried to compile your patch with few versions of x3270 from back of 2018 and it looks like dependencies and bunch of stuff isn't going to work the easy way.
Did you manage to build the tool recently? Which version of x3270 have you used?
Did you port py3270 to python 3?

I compiled birp and x3270 on kali and on BlackArch with same result. I get the folowing stack trace :

Traceback (most recent call last):
File "birp.py", line 544, in menu(em, history)
File "birp.py", line 469, in menu interactive(em,history)
File "birp.py", line 180, in interactive if not em.is_connected(): File "/usr/lib/python2.7/site-packages/py3270/init.py", line 328, in is_connected self.exec_command(b'ignore') File "/usr/lib/python2.7/site-packages/py3270/init.py", line 291, in exec_command c.execute() File "/usr/lib/python2.7/site-packages/py3270/init.py", line 69, in execute return self.handle_result(result.decode('ascii')) File "/usr/lib/python2.7/site-packages/py3270/init.py", line 87, in handle_result raise CommandError(msg.decode('ascii')) py3270.CommandError: Unknown action: ignore

The files have been moved in the new version of x3270 (3.5ga11 stable (26. June 2017)) So the patch doesn't work straight forward.
I'm not sure all the lines are correctly patched, I'll check that tomorrow.

Any chance you could get this working on windows ?
Probably have to write the getch keymap and then
x3270 not supported on Windows warning error

When starting birp up, it crashes.
