didnt realize there would be different responses from sudo -i login, vs just sudo ./
here's the response as root in terminal
root@brent3:/home/bab# chmod +x rt2870.bin
-bash: ./rt2870.bin: cannot execute binary file
same as bab's non sudo.
edit- its a debian system
bab@brent3:~$ file rt2870.bin
Well, either it is an executable for another operating system, or it was not downloaded properly. Does the source site have a checksum (md5 or sha1) available to verify that the file you got is what they have?
I had the same problem. Guide me as well if any one know the solution.
