Sent  that email  on accident without completing it..


Anyway so far I have come up with this..



import os

PORT = int(raw_input("What tcp/udp should I watch for?: "))

os.popen('netstat -an>log.txt')

LogFile = file('log.txt', 'r')
logcontents = LogFile.read()
inFile.close()
print logcontents




So far so good.  The "print logcontents" will print the output from the 
netstat command. My question is this.
I'm trying to figure out a way to search "logcontents" for the "PORT" 
variable then perfrom a action if it finds
a match.

Thanks
