Method Details [hide private]

__init__(self, owner)
(Constructor)

source code  
initialize

owner -- object who starts the connection

isConnected(self)

source code  
check if this connection is still alive

connect(self, host, user, port, auth, passwd=None, keyFile=None, passphrase=None)

source code  
make a ssh2 connection to the remote host. 

host -- remote host machine
user -- username 
port -- port of remote ssh service
auth -- authenticate method, PSWDAUTH,RSAAUTH,DSAAUTH
passwd --  only required if use PSWDAUTH
keyFile -- only required if use RSAAUTH or DSAAUTH
passphrase -- only required if use RSAAUTH or DSAAUTH, and passphrase is set

__rsa_auth(self, transport)

source code  
Authorize connection with default rsa key location.

transport -- paramiko transport

__dsa_auth(self, transport)

source code  
Authorize connection with default dsa key location.

transport -- paramiko transport

getXMLRPCTransport(self)

source code  
make a HTTP transport to remote host through SSH tunnelling. 

return: a xmlrpc  transport instance

openTunnel(self, address)

source code  
As requested by xmlrpclib.Transport, open a ssh2 tunnel

address -- host:port string
return: a sshe tunnel

execute(self, cmd, n=1024)

source code  
execute a command

cmd -- command to be run remotely
n -- size of output to be returned
return -- output
