SSH from jython using jsch

python_ssh_jsch.py

I have to make ssh calls from python, there are few options

however we run in jython and it runs automated, so adding extension is difficult.

luckily we have access to jsch jars. 

here is a example on how to connect to a ssh server using jsch from python/jython

from com.jcraft.jsch import JSch

from org.python.core.util import FileUtil
from java.lang import System

jsch=JSch()


host="10.3.407.170"; #intentionally  wrong here
user="myuser"
session=jsch.getSession(user, host, 22);
session.setPassword("coolpassword");

session.setConfig("StrictHostKeyChecking", "no");

session.connect();

command="ls"

channel=session.openChannel("exec");
channel.setCommand(command);

# X Forwarding
# channel.setXForwarding(true);

#channel.setInputStream(System.in);
channel.setInputStream(None);

#channel.setOutputStream(System.out);

#FileOutputStream fos=new FileOutputStream("/tmp/stderr");
#((ChannelExec)channel).setErrStream(fos);
channel.setErrStream(System.err);
instream=channel.getInputStream();

channel.connect();


fu = FileUtil.wrap(instream)

for line in fu.readlines():
print line

if channel.isClosed():
    print "exit-status: "+channel.getExitStatus()

try:
    Thread.sleep(1000)
except:
    print e

channel.disconnect();
session.disconnect();
