Reading a portion of a file

[Vulcanius]

Here is the code I've come up with. Please feel free to critique it
and let me know what you would change. Also, as you can see I call
"open(SERVER,'r')" twice; but I want to only call it once, what would
the best way to do this be?

------------------------------------------------------------

import re

SERVER = "192.168.1.60"

# Pull all data from server file.
FILE = open(SERVER,'r')
ALLINFO = FILE.read()

# Grab a list of all sections in the server file.
SECTIONS = re.findall("(?m)^\#VS:\w*:.*:", ALLINFO)

# Remove duplicates from the list.
if SECTIONS:
   SECTIONS.sort()
   LAST = SECTIONS[-1]
   for I in range(len(SECTIONS)-2, -1, -1):
       if LAST==SECTIONS[I]: del SECTIONS[I]
       else: LAST=SECTIONS[I]

# Pull data from each section and assign it a dictionary item.
# Data can be called using SECTIONDICT['section'] i.e
SECTIONDICT['df']
SECTIONDICT = {}
for SECT in SECTIONS:
    PRESECTNAME1 = SECT[9:len(SECT) - 1]
    PRESECTNAME2 = PRESECTNAME1.split("/")
    SECTNAME = PRESECTNAME2[len(PRESECTNAME1.split("/")) - 1]
    START = SECT + "START"
    STOP = SECT +  "STOP"
    for LINE in open(SERVER,'r'):
        LINE = LINE.strip()
        if START in LINE:
            SECTIONLISTTEMP = []
        elif STOP in LINE:
            SECTIONDICT[SECTNAME] = SECTIONLISTTEMP
            SECTIONLISTTEMP = []
            print "-" * 80
            print "SECTION: %s" % SECTNAME
            print SECTIONDICT[SECTNAME]
        else:
            if LINE:
                SECTIONLISTTEMP.append(LINE)

FILE.close()
