Hello Phillip,

  I am not sure whether interpreter can execute "    if (expect[0] == 1):",
but maybe it is better to execute the whole script as one string instead of
executing it line-by-line.

- Alexey.

Subject: [Jython-dev] jython/yelnetlib

 

Hello - 

I am new to jython and think that it is quite cool - - - Howerver  - It seem
s t be missing what i need - & I think I might just be looking in the wrong
place...

I am trying to write a quick program that will go and telnet to a unix box,
login and see what group membership a user has.

I also have wider ranging needs to be able to telnet from java.

So I looked at using java sockets for telnet - but this is much more
complicated than writing your own client AND server sockets and then sending
text back and forth - which i have done successfully in the past.  

Telnet requires much more than simple sockets.

So I tried to write a python program to do the telnetting using Jython 2.1.
I successfully wrote a python program to telnet to a machine and determine
user groups - all should be great!!!

Now - I try to glue the whole thing together and Jython will not run the
script!  Included in the lib folder of jython is the telnetlib.py, but i
cannot call it from the java program...

Do I need to do anything else before running this java/jython code?  Is
there a better way to do this?



Thanks  -
