Package: pyhoca-cli
Version: 0.5.0.4

(sorry for repost, I subscribed now to the mailinglist)

Hi,

pyhoca-cli stopped working for me. I expected it to ask me for password,
but instead it raises an exception.

I don't know what happened, because this worked all the time. And I
think I didn't change anything.

The error message is: "ValueError: CTR mode needs counter parameter, not IV"


Used command:

pyhoca-cli --server xxxxxxx -u xxxxxx -R
xxxx-xx-xxxxxxxxxx_xxxxxxxx-session_xxxx

exact apt versions of my client:
pyhoca-cli 0.5.0.4-0~231~ubuntu16.04.1
python-paramiko 1.16.0-1

Probably an incompatibility issue with newer versions of Paramiko. Will have to
look into this.

without changing anything, pyhoca-cli works for me now, but it displays
a warning:

"/usr/lib/python2.7/dist-packages/Crypto/Cipher/blockalgo.py:141:
FutureWarning: CTR mode needs counter parameter, not IV
  self._cipher = factory.new(key, *args, **kwargs)"

When I tried it today, a window poped up asking me for my passphrase
which I need for something else...

And it worked.

But I dont use a keyfile or this passphrase for this x2go related server.

Maybe this information is useful.

But all thinks work for now.
