Wireshark · Wireshark-users: [Wireshark-users] Clue on sshdump w/special characters in passwords

[Jason Lixfeld <jason+wireshark@xxxxxxxxxx>]

Hi,

I’m wondering if anyone has some clue on a sshdump GUI oddity.  The attempt to start the sshdump always seems to result in an authentication failure when a special character is used in the password:

Error by extcap pipe:
** (process:27640): WARNING **: Error creating connection.

** (process:27640): WARNING **: Can't find a valid authentication. Disconnecting.

Is there some magic required to use special characters in passwords?

Thanks in advance!
