Hi all,
I'm really new to Python programming, only been tinkering with it a couple of days. I started writing this program and can't quite work out what I'm doing wrong. I want the user to enter the details in the dialog box and then when they hit execute it runs the telnet stuff and writes the output back to a file. I'm obviously doing something really stupid and need some help.
Any pointers would be great.
Cheers
Lee
My code :
import telnetlib
import sys
import Tkinter
from Tkinter import *
def detail() :
telnet = telnetlib.Telnet(HOST)
telnet.read_until("login: ")
telnet.write(USER + "\n")
telnet.read_until("Password: ")
telnet.write(PASSWORD + "\n")
telnet.write("ls -l /etc/init.d/oracle.sh\n")
telnet.write("ls -l /etc/rc3.d|grep orac\n")
telnet.write("cat /etc/oratab\n")
telnet.write("exit\n")
info = telnet.read_all()
file = open('c:/temp/listing.txt', 'w') #write info to file
file.writelines(info)
file.close()
login = Tk()
Label(login, text="User Name:").grid(row=0, sticky=W)
Label(login, text="Password:").grid(row=1, sticky=W)
Label(login, text="Host:").grid(row=2, sticky=W)
entry_ln = Entry(login)
entry_fn = Entry(login)
entry_ph = Entry(login)
USER = entry_ln.grid(row=0, column=1)
PASSWORD = entry_fn.grid(row=1, column=1)
HOST = entry_ph.grid(row=2, column=1)
b_execute = Button(login)
b_execute['text'] = "Execute"
b_execute['command'] = detail
b_execute.pack()
b_execute.grid(row=7, column = 1)
login.mainloop()
The errors I'm getting:
Exception in Tkinter callback
