If you iterate over a string, you are iterating over individual
characters. Instead, you need to split it into lines, first stripping
whitespace (starts and ends with an empty line).

s = s.strip().replace("=",":")
print s

d = {}


I'd use .splitlines instead:


for i in s.split('\n'):
 try:


.partition works better here. You should note that the "Mac Addr" line 
has multiple colons, most of which are part of the value!



 key, val = i.split(":")
 d[key.strip()] = val.strip()
 except ValueError:
 print "no key:value pair found in", i



s = s.replace("=",":")
d = {}

for line in s.splitlines():
key, sep, val = line.partition(":")

if sep:
d[key.strip()] = val.strip()
else:
print "no key:value pair found in", line

If you iterate over a string, you are iterating over individual
characters. Instead, you need to split it into lines, first stripping
whitespace (starts and ends with an empty line).

s = s.strip().replace("=",":")
print s

d = {}
for i in s.split('\n'):
try:
key, val = i.split(":")
d[key.strip()] = val.strip()
except ValueError:
print "no key:value pair found in", i

IPv4 address configured by DHCP

It doesn't find key and value for above string.

Solution.. Use one complete string per  line
