Hello,

Follow your output; In the scan file, on line 35, what is it trying to do? Also, check your permissions on both files, and make sure that they are chmod'd for +x.

Cheers,

Josh

./bfr -m 0 -i 1k -b 50m $SESSION | while read LINE; do
Line 35!

[root@clw1 school proj]# ./bfr
bash: ./bfr: cannot execute binary file

Like I have said before, have you checked the permissions? Navigate to the directory where bfr is located, and enter the following:

Code:

ls -al

This will show you the permissions the file has, and it needs to have the execute permission in order to run it. To make sure of this, enter the following:

Code:

chmod +x bfr

Also, you might have to run it as root, depending on the permissions and the ownership of the file.

Cheers,

Josh

http://bfr.sourcearchive.com/documen...8c-source.html here is the source

[root@clw1 school proj]# file bfr

Could it be you are using a 64 bit version on a 32 bit system?

Kind regards

[root@clw1 school proj]# uname -m
i686
[root@clw1 school proj]#

druuna · 07-08-2011, 12:12 PM

Guess you now know why it doesn't work

i686 = 32 bit and x86_64 = 64 bit

AngryBeast · 07-08-2011, 12:16 PM

OMG!!!!! HOW NOOOB I AM !!!!! is there any posibility to upgrade to x64 ? or i need to reinstall a fresh x64?

corp769 · 07-08-2011, 12:36 PM

You could always recompile for your system
