If you're 100% positive you have execute permissions on the file, then I would suggest cracking open your /etc/fstab file. Look up the entry for the partition that holds your executable, and look at the options (fourth column). If you see "noexec" in the list, then the system is set up to prevent executing any file on that partition... period. That's sometimes done for FAT32 partitions by the distro installer.

humm i just checked changed my fstab to:

/dev/sda1 /home auto exec,users,rw,noatime 1 2

and then re-mounted, and i get the same problem, however if i copy and past the bin files to my / directory on /dev/hda1 they run fine?!? have you got any other ideas?? cheers

What you describe sounds like the noexec attribute is still active (assuming you had to modify the entry in /etc/fstab).

Now, when you say you remounted it, did you mount it again at another spot in the filesystem, mount it on top of the other mount, mount with the remount option, or a full umount & mount routine?

I would suggest doing the full umount. If that doesn't work, I'm not sure what else to suggest. There's always the reboot option
