RPyC and EC2

[Brian Pribis]

I'm simply trying to get the sample running for doing RPC over SSH:

from rpyc.utils.zerodeploy import DeployedServer
from plumbum import SshMachine

# create the deployment
mach = SshMachine("stage.myhost.com")
server = DeployedServer(mach)

# and now you can connect to it the usual way
conn1 = server.classic_connect()
print conn1.modules.sys.platform

conn2 = server.classic_connect()
print conn2.modules.os.getpid()

# when you're done - close the server and everything will disappear
server.close()

This connecting to an EC2 from our local network. I actually opened up all my UDP/TCP ports to the world to see if that was the issue (clearly I wouldn't want that even if it did work, but I was just trying to rule out a firewall issue).  Either way I get:

Enter passphrase for key '/home/brian/.ssh/id_dsa':
Traceback (most recent call last):

    line = self.pipe.readline()
ValueError: I/O operation on closed file


I know that once the SSH connection is made, a random port is setup to tunnel with, so maybe that is the issue,  but I'm not entirely sure.

Any push in the right direction would be helpful.
