Problems described in this file are (if you encounter an unknown problem,
thanks for contacting me, as described at the end of this file) :


WHILE EXECUTING
 1: Popup : The dynamic library wpcap.dll was not found. 
    [Note : I'am not sure about the exact error message because I do not 
    have access to an English computer]
 2: Display is slow.
 3: The system crashes when lcrzoex is run.
 4: Lcrzo is slow.

WHILE SNIFFING

Problem 1 :
  Problem synthesis :
    Popup : The dynamic library wpcap.dll was not found. 
    [Note : I'am not sure about the exact error message because I do not 
    have access to an English computer]
  Environment affected by the problem :
    Windows
  What's causing the problem :
    WinPCAP is not installed.
  Solution :
    Download and install WinPCAP as described in INSTALL_EN.TXT
    or INSTALLWINDOWS_EN.TXT.

-------------------------------------------------------------------------------
Problem 2 :
  Problem synthesis :
    Display is slow.
  Environment affected by the problem :
    Windows
  What's causing the problem :
    In a msdos console, we cannot print more than 100 lines per seconds.
  Solution 1 :
    Redirect output in a file :
      commandname > fichier
    However in this case, we do not see when data has to be entered.
  Solution 2 :
    Use tools, or printprofiles, less verbose.

-------------------------------------------------------------------------------
Problem 3 :
  Problem synthesis :
    The system crashes when lcrzoex is run.
  Environment affected by the problem :
    Windows
  What's causing the problem :
    Under Windows 95/98, when a network board is not correctly configured,
    the driver cannot be opened by WinPCAP (PacketOpenAdapter). The driver
    crashes, and also the system.
  Solution :
    We have to ensure the network card is correctly configured :
    [menu names might be incorrect, because I do not have access to
    an English localized computer]
     - Open menu Start, Parameters, Configuration, Icon System,
       Periphericals, Network Cards. You should see one line per card.
       Moreover, the icon should not have "(!)" on top of it.
     - Open menu Start, Parameters, Configuration, Icon Network.
       The network card should be here, and linked to TCP/IP. Moreover
       TCP/IP configuration should be correct.

-------------------------------------------------------------------------------
Problem 4 :
  Problem synthesis :
    Lcrzo is slow.
  Environment affected by the problem :
    All
  What's causing the problem :
    I choose to create a modular library, easy to use.
    One of the consequence is the high level structuration of lcrzo.
    So, it is slower than a low level programming interface.
  Solution 1 :
    Using records (lcrzo_record.h), you can construct your packets,
    save them, and then send them.
  Solution 2 :
    You can also use only low level fonctions of lcrzo, and create
    your specific code around.
    If its still too slow, you should not use lczro and use directly
    system's functions, or buy a new computer ;)

-------------------------------------------------------------------------------
Problem 5 :
  Problem synthesis :
    The sniff does'nt work with a modem.
  Environment affected by the problem :
    Windows with a modem
  What's causing the problem :
    For the moment, lcrzo :
     - supports Ethernet network cards
     - doesn't support modems
  Solution :
    There is no solution. If you have time, you may want to help me to do 
    it. Thanks.

-------------------------------------------------------------------------------
Problem 6 :
  Problem synthesis :
    The sniff does'nt work with a modem.
  Environment affected by the problem :
    Windows with a modem
  What's causing the problem :
    For the moment, lcrzo :
     - supports Ethernet network cards
     - doesn't support modems
  Solution :
    There is no solution. If you have time, you may want to help me to do 
    it. Thanks.
