** Summary changed:
- sshuttle doesn't support python 3.5
+ sshuttle doesn't autodetect python3 instead of 'python'
** Description changed:
+ [impact]
+
+ connecting with sshuttle to a remote system where the only version of
+ python is python3 named 'python3' and no binary named 'python' fails
+
+ [test case]
+
+ from a x/b system, attempt to sshuttle to a remote system where only
+ 'python3' exists, and no 'python' binary exists
+
+ [regression potential]
+
+ any regression would likely cause problems with the initial sshuttle
+ connection; it's unlikely any issues would be caused after the
+ connection is successfully established.
+
+ [scope]
+
+ this is needed only in x/b.
+
+ this appears to be fixed upstream with commit
+ 9b7ce2811ec3ef35b9b7f7dfc157127bc46ece47 which is included starting in
+ v0.78.4, so this fixed already in focal and later.
+
+ [original description]
+
sshuttle package implementation doesn't support Python 3.5 on remote
host running Xenial and late from a machine <= Wily release.
This cause the connection to fail if the connection is negotiated from a
Precise, Trusty or Wily machine and if the remote host is running Xenial
(16.04).
Example took from "Wily" :
$ sshuttle -r <REMOTE_SERVER> <TARGET_REMOTE_SUBNET>/0 -vv
Starting sshuttle proxy.
UDP support requires tproxy; disabling UDP.
Binding redirector: 12300 12299
TCP redirector listening on ('127.0.0.1', 12299).
firewall manager ready method nat.
c : connecting to server...
