backup licenses

Hi,

I have two QNX 4.25 license floppies (OS/ Watcom C++) for which I need a
backup copy. I know both floppies work fine. But I am unable to mount the
floppy in order to read it. I get an error message saying ‘corrupted file
system detected’. Any pointers on how to make backup of those license
floppies are appreciated.

thanks

cp /dev/fd0 backupfile
cp backupfile /dev/fd0

Or if you have two floppy drives

cp /dev/fd0 /dev/fd1

Compile the following program and run it. It will convert the licenses to normal files
that can then be cp’d and backed up.

#ifdef __USAGE
This utility allow you to backup your system with license
#endif

#include <unistd.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <process.h>
#include <fcntl.h>
#include <dirent.h>
#include <time.h>
#include <errno.h>

main()
{
DIR *dp;
struct dirent *dirp;
int fd;
FILE *fp;
char buf[512], fn[64];

if ( geteuid() != 0 )
exit(-1);

umask( 077 );

dp = opendir("/etc/licenses");
if( !dp ) exit(0);
while(dirp = readdir(dp))
{
if(dirp->d_name[0] == ‘.’)
continue;

memset( buf, 0, sizeof(buf) );

sprintf( fn, “/etc/licenses/%s”, dirp->d_name );
fd = open( fn, O_RDONLY );

if( fd != -1 )
{
if( block_read(fd, 1L, 1, buf) == -1 &&
(errno == ENOSYS || errno == EOPNOTSUPP))
read(fd, buf, 512);
close(fd);

strcat( fn, “X” ); fp = fopen( fn, “w” );
if ( fp )
{
fwrite( buf, 1, 512, fp );
fclose( fp );

strcpy( buf, fn );
fn[ strlen(fn)-1 ] = ‘\0’;
unlink( fn );
rename( buf, fn );
}
}
}
}

Cheers,
Camz.
