JTAG : Unable to lock chain on CentOS 5

Hi

I have one probleme with my usb blaster on CentOS 5.5.

Unable to lock chain (Insufficient port permissions).

I have found a topic on this on the forum but from 2007 and I want to know if the procedure here is up to date yet.

http://www.alteraforum.com/forum/showthread.php?t=1207&highlight=usb+blaster

And the nioswiki (at http://www.nioswiki.com/operatingsystems/uclinux/quartusforlinux) do not say the same procedure which is for ubuntu and Suse (as written in the "setup JTAG" section)

Can you help me ?

    Please kill jtagd process. And run it as root.

    mkdir /etc/jtagd

    cp /opt/altera9.1sp1/quartus/linux/pgm_parts.txt /etc/jtagd/jtagd.pgm_parts

    Add these lines to /etc/rc.local to start jtagd server. As root or via sudo.

    /opt/altera9.1sp1/quartus/bin/jtagd
