Can I do it using python?? about xterm and telnet
I'm a net admin for about 20 unix servers, and I need to frequently telnet on to them and configure them. It is a tiring job to open a xterm and telnet, username, password to each server. Can I do it automatically by python? After that, there have 20 xterm consoles opened and telneted to their corresponding servers. Then I could start to type command in these xterms. Any suggestion appreciate. Much thanks. -- http://mail.python.org/mailman/listinfo/python-list

Thanks, But I need to to do complicated job in the xterm consoles for servers. So I need to open many xterm consoles and I just want to save my time from telneting...usr/pwd...

Re: Can I do it using python?? about xterm and telnet
I don't care about security issue by now :), because every one in my compony know the username/password. It's a shared password. I just want to login into Unix boxes in an efficiently. so I needn't open a xterm console and type telent . usr/pwd for a unix box, and open another xterm, type telnet ...usr/pwd, and so on...

telnet server must have a password, right?

Re: Can I do it using python?? about xterm and telnet
Maybe I'm not state what I want clearly. These Unix boxes are not doing important job like email, web server, etc. In our lab, these unix boxes are connected to be a network system to run our protocols and our job is to test the protocols. they are physically seperated from lab network and seperate from Internet. So I do not consider the security issue. There will be a lot of work to do after I login into these servers. I'm tired to typing the command "telnet".. and I want to do "telnet" automatically.

how to convert from Decimal('1.23456789') to Decimal('1.234')
I only need the 3 digits after '.' Is there any way other than converting from/to string? -- http://mail.python.org/mailman/listinfo/python-list
How can I do bit operation on python float value
I have a python float 1.2345678. I know that it is stored as a double in C type. And I know it actually is 1010101010101 -like format. Then I want to do some bit operation on it. How? Sure, I want a float output when I finish the operation. -- http://mail.python.org/mailman/listinfo/python-list

The pack way is to convert float to/from string, Is it efficient? valpa -- http://mail.python.org/mailman/listinfo/python-list
