Kippo error connection lost - bad packet length #231
Description
Hello all,
I'm building Kippo Honeypot, but I have a problem connection lost when I access Kippo via SSH and bad packet length error when I access Kippo via Telnet.
Logging displays when I access Kippo via SSH.

I appreciate any your idea...
Thank you so much
