[Ethereal-users] ftp-data

[Giorgio Mulas]

Hi everybody, I performed the following experiment: 3 pc in wi-fi ad hoc mode: two of them exchange an mp3 in ftp binary mode, the third is sniffing (tethereal).   Then I apply the filter ftp-data and save the packets. I think the packets are now in ASCII. I convert the saved ASCII packets in binary with the following c++ program:               ifstream fin("ftpsaved");             ofstream fout("binary.mp3",ios::binary);             char b;             long i=0;             while(!fin.eof())             {                         fin.read(&b,sizeof(char));                         cout << fin.tellg() << endl;                         fout.write(&b,sizeof(char));             }             fin.close();             fout.close();   now I can play the mp3, see its idtag….but the mp3 is damaged! Any ideas about the problem?   Thanx   Giorgio.
