Due to python3 on remote system: OSError: [Errno 88] Socket operation on non-socket

[Peter Valdemar Mørch]

When trying to connect from Ubuntu focal 20.04 to Ubuntu focal 20.04 i get an error. This does not occur with version 1.0.3

The error is:

$ sshuttle -r user@remote 10.164.0.0/20
[local sudo] Password:
assembler.py:3: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
client: Connected.
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "assembler.py", line 38, in <module>
  File "sshuttle.server", line 298, in main
  File "/usr/lib/python3.8/socket.py", line 544, in fromfd
    return socket(family, type, proto, nfd)
  File "/usr/lib/python3.8/socket.py", line 231, in __init__
    _socket.socket.__init__(self, family, type, proto, fileno)
OSError: [Errno 88] Socket operation on non-socket
client: fatal: server died with error code 1

This is reported here: https://github.com/sshuttle/sshuttle/issues/381

Workaround: Installing python2 on remote system and running with:

$ sshuttle --python=/usr/bin/python2 -r user@remote 10.164.0.0/20

Makes it work

Also,

mkdir try
cd try
virtualenv .
./bin/pip install sshuttle
./bin/sshuttle -r user@remote 10.164.0.0/20

works too

$ ./bin/sshuttle --version
1.0.3
