Connection error with fw 2.15.0.1052

[ldecicco]

As per subject rmview cannot connect to tablet after the latest update. This is the error I have:

Traceback (most recent call last): File "/usr/local/lib/python3.9/site-packages/rmview/connection.py", line 178, in run self.client.connect(self.address, **self.options) File "/usr/local/lib/python3.9/site-packages/paramiko/client.py", line 406, in connect t.start_client(timeout=timeout) File "/usr/local/lib/python3.9/site-packages/paramiko/transport.py", line 699, in start_client raise e File "/usr/local/lib/python3.9/site-packages/paramiko/transport.py", line 2110, in run ptype, m = self.packetizer.read_message() File "/usr/local/lib/python3.9/site-packages/paramiko/packet.py", line 459, in read_message header = self.read_all(self.__block_size_in, check_rekey=True) File "/usr/local/lib/python3.9/site-packages/paramiko/packet.py", line 303, in read_all raise EOFError()

Notice that:

• I am on Ubuntu latest version
• I have exactly the same error when running rmview in a Docker container
• I can successfully connect in ssh
• reStream works

The issue looks to be due to paramiko.
EDIT:
I have enabled paramiko debug log level and got this:

Looks like a Paramiko issue indeed.
Could you try downgrading paramiko to, say, 2.7.2?

[ldecicco]

Thanks for the suggestion. Unfortunately, I am still having issues with paramiko 2.7.2.

I'm running rmview with paramiko at 2.11.0, I cannot reproduce your issue.
Do you mind sharing your configuration? (Please erase passwords or sensitive bits beforehand)
