Hello,
I was trying to add an option to iperf to allow for dumping data from a
file transferred using UDP. I can successfully transfer a text file and
obtain a dump for it at the server, but there are a couple of problems:
* The beginning of the file is not transferred (I see some random
symbols in the beginning)
* ^...@^@^...@^ak1u
^...@^@;=...@^@^...@^@^...@^@^...@^@^...@^@^...@^@^...@^@^S
^...@^@^...@^@^...@^@^...@^@yyix
* I get random symbols (similar to above) in the middle of the
text I transfer
* "more disturbing" is dumped as "more d...@^@^...@^bk1u
^...@^@l...@^@^...@^@^...@^@^...@^@^...@^@^...@^s^@^...@^p^@^...@yyixisturbing"
* The appearance of these symbols seems periodic
I added the following code to PerfSocket:: Recv_UDP
InitTransfer();
+ FILE *fpnt;
+ if ( ( fpnt = fopen ( "output.txt", "w" ) ) == NULL )
+ {
+ /* if you can't open the output.txt file for some reason //
+ * print the words: cannot open file*/
+ printf("File could not be opened. Cannot output to file!!");
+ }
do {
// perform read
currLen = read( mSock, mBuf, mSettings->mBufLen );
+ int i = 0;
+ while ( i != currLen )
+ {
+ fprintf( fpnt, "%c", mBuf[i]);
+ i++;
+ }
sReporting.Unlock();
+ fclose( fpnt );
// send a acknowledgement back only if we're NOT receiving multicast
Any hints as to why this is happening would be much appreciated. All
questions, comments or remarks are welcome.
