sniffer in python

[billiejoex]

Thanks for your help. Like you suggested I converted the integer value in a
string one by using the repr() funtion applied on the print:

print '%d \n %s' %(count, repr(iface))

The program now permit me to select the interface. The output is in a
strange hex-similar form:

C:\Python24>test.py

Can you guess anything about what in that linemight be causing an encode() call?  The count variable is, presumably, justan integer, so %i wouldn't like have to do more than convert it to a string.%s, however, asks for "iface" to be turned into a string... if it were notalready a string (i.e. it's a unicode?) it would have to be encoded.  Whatdoes iface contain and where did it come from?  Can you make it be just astring?  Does that change or fix anything?>> -Peter
