tmda-1.0.3
The previous posts about patches reminded me that I should at least
get this one into the mail archives.
I ran into a situation where a mis-configured PC e-mail client was
efectivly causing a DOS attack on tmda-ofmipd.
The error reported was
....
error: uncaptured python exception, closing channel
<__main__.TMDAProxy listening localhost:8025 at 0x81fddcc>
(socket.error:(22, 'Invalid argument')
[/opt/mt/python-2.3/lib/python2.3/asyncore.py|read|69]
[/opt/mt/python-2.3/lib/python2.3/asyncore.py|handle_read_event|384]
[/opt/sbin/tmda-ofmipd|handle_accept|1022] [<string>|getsockname|1])
....
The attached patch seems to keep tmda-ofmipd from crashing.
