This code works perfect when using a machine with only one interface online. (Excluding the loopback of course) But when I have other interface up for vmware or a vpn the output gets mixed up.

GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.
I am assuming that sed, awk or even perl could do what I need.

Hi,
I have a huge list of archives (.gz). Each archive is about 40MB. A file is generated every minute so if I want to analyze the data for 1 hour I get already 60 files for example.

What I need to do is to... (11 Replies)
I need your help to discover missing elements for each box.
In theory each box should have 4 items: ITEM01, ITEM02, ITEM08, and ITEM10.
Some boxes either have a missing item (BOX02 ITEM08) or might have da duplicate item (BOX03 ITEM02) and missing another one (BOX03 ITEM01).

pydhcplib.strlist
pydhcplib.strlist(3) PYDHCPLIB pydhcplib.strlist(3)NAME
pydhcplib.strlist - Internal type of pydhcplib for lists of bytes processing.
SYNOPSIS
from pydhcplib.type_hw_addr import hwmac
a = strlist()
a = strlist([100,100,10,42,44,26])
DESCRIPTION
The class pydhcplib.strlist is an specific type of pydhcplib. It exist in order to simplify processing of raw data from network. When a
dhcp packet dhcp is received, it's a succession of approximately 300 bytes. Within pydhcplib these data are transformed in an intermediary
form of type "strlist" in order to facilitate their handling. This intermediary form will eventually be suppressed in the stable versions
of pydhcplib to speedup the processing time, but backward compatibility will be assured.
The pydhcplib.strlist class creation argument can be a list of numbers whose value goes from 0?55.
The pydhcplib.strlist class creation argument can be a string of ASCII character.
METHODS
The implemented methods in this type are mostly comparison methods (= =, >, etc...)
else :
str() convert the address into a printable string type.
list() convert the address into a list of bytes.
EXAMPLES
Example program strlist_example.py :
from pydhcplib.type_strlist import strlist
word = strlist()
word1 = strlist("azerty")
word2 = strlist("qwerty")
word3 = strlist([97, 122, 101, 114, 116, 121])
print "a0 : ",word
print "a1 : ",word1
print "a2 : ",word2
print "a3 : ",word3
if word1 == word2 :
print "test 1 : ",word1, "==",word2
else :
print "test 1 : " ,word1, "!=",word2
if word1 == word3 :
print "test 2 : ", word1, "==",word3
else :
print "test 2 : ", word1, "!=",word3
