Python implements a digital device tftp backup configuration file Sample _python

Environment: "Wind2003[open Tftp Server] + VIRTUALBOX:UBUNTN10 Server"
Tftp:open TFTP Server
Ubuntn
Python + pyexpect
Virtual machine Reason: Pyexpect does not support windows

Note: Originally intended to use SECRUECRT script, because the practice found no use under Linux pexpect easy-to-use, flexible, used to use expect, because TCL "grammar" without Python easy-to-use, easy to maintain

Write some procedural reasons:
Recently a more serious failure: Due to NetScreen device bugs, a node main standby equipment at the same time, the replacement of equipment, found that the backup configuration file garbled "Chinese", can not be used directly.
Consider equipment in the intranet, there are currently nearly 300 digital access equipment, so the original TFTP backup method
Due to a few backup devices: temporarily consider the function, program efficiency in the secondary

Release:
Basic implementation of Netscreen,cisco iOS, HW vrp,h3c f1000 Device Backup Program
Isolate device information Configuration 2. Increase the success of a backup test

Problem:
1 unresolved ping unreachable Main, feedback slow problem Resolution: IP One, do not support host name, add check address in Ipcheck function to solve
2. Login device deployment Expect code, no processing authentication failure, or timeout and other basic check problems
