[U-Boot-Users] tftp from AT91RM9200DK to Red Hat 8.0 tftp server p roblems
I have a problem doing tftp from U-Boot to my Red Hat 8.0 Linux machine Is there a known problem with tftp to Red Hat Linux machines in U-Boot?
Make sure that you do "sudo service iptables stop" before attempting to have your target hardware use tftp -- it's quite possible you installed the firewall when you installed Red Hat, the default now is to do so.
=> Thank You James! ExactIy what I needed!

I think this is VERY BAD advise.
Of course you ALWAYS want ot have your firewall running if you need one (and then you must take care to configure it correctly); otherwise you should just permanently disable / unconfigure / uninstall it.
Just disabling the firewall to get something doen whichis otherwise impossible because of problems you don;t understand is just what the crackers are waiting for. Be aware.
NEVER disable a firewall if you need one. Not for 5 seconds.
