If you find errors, thanks for contacting me. For every bug report, try to indicate : - netwib/netwox/netwag version - libpcap/winpcap version - libnet version (Unix only) - result of the command : netwox 2 - system (uname -a under unix) - command or error environment - how to reproduce the error - the patch, if you wrote one - other information you may think useful As of June 2012, my email address is : laurentconstantin@free.fr How to create a patch (Unix only) ? - Solution 1 : One file was modified : compare the modified file with the original file : diff -ub file.c.original file.c > /tmp/file.c.patch - Solution 2 : Several files were modified : compare the modified directory with the original directory : diff -urbaN netwib-5.39.0-src netwib-5.39.0-src.modified > /tmp/dir.patch - Suggestion : If you haven't done the changes, use preferably this method : cd ../.. cp -R netwib-5.39.0-src netwib-5.39.0-src.modified cd netwib-5.39.0-src.modified [do your modifications, compilations, tests, etc.] cd .. diff -urbaN netwib-5.39.0-src netwib-5.39.0-src.modified > /tmp/dir.patch Then, I'll apply the patch with : patch -Nbp1 < file.c.patch patch -Nbp0 < dir.patch
