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

This file describes known problems (incompatibilities, unsupported
functionnalities, errors, etc.).
If you seek help (usage help, examples, etc.), it's better to read 
lcrzo-4.xx-doc_html.tgz.

Problems described in this file are (if you encounter an unknown problem,
thanks for contacting me, as explained in ./doc/problemreport_en.txt) :

WHILE EXECUTING
 1: Several tools of lcrzoex doesn't seem to work.
 2: 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]
 3: Display is slow.
 4: The system crashes when lcrzoex is run.
 5: At lcrzo end, the modem link stops.
 6: Lcrzo is slow.

Currently, there is nothing to say.



-------------------------------------------------------------------------------
Problem 1 :
  Problem synthesis :
    Several tools of lcrzoex doesn't seem to work.
  Environment affected by the problem :
    Windows
  What's causing the problem :
    Lcrzo depends on WinPcap. If WinPcap does not work, several
    functionalities of lcrzo/lcrzoex will not work.
    So, we have to ensure WinPcap works correctly.
  Solution :
    Install and test windump as described in INSTALL_FR.TXT.

-------------------------------------------------------------------------------
Problem 2 :
  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 3 :
  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 4 :
  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 5 :
  Problem synthesis :
    At lcrzo end, the modem link stops.
  Environment affected by the problem :
    Windows 95 with a modem
  What's causing the problem :
    At the end of a program, references to unused object are freed.
    It's the case for the low level driver of WinPcap (packet.sys).
    Unfortunately, as explained in WinPcap FAQ, Windows also
    stops the modem connection. So, at the end of lcrzoex, the phone
    line stops.
  Solution 1 :
    Installation of :
     - Windows Sockets 2 Update, and
     - Dialup Networking 1.3 Update
    might resolv this problem. 
    Those updates are available here :
     - http://www.microsoft.com/windows95/downloads/contents/wuadmintools/s_wunetworkingtools/w95sockets2/default.asp
     - http://www.microsoft.com/Windows95/downloads/contents/WURecommended/S_WUNetworking/dun13win95/Default.asp
  Solution 2 :
    You can contact WinPcap developers to help them to write a 
    driver/dll not having this problem.

-------------------------------------------------------------------------------
Problem 6 :
  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 ;)
