Hi All, I have two servers, one is RHEL 5.3 , another Ubuntu 9. When I setup tftp sevice on two servers, I can use this command: boot RHEL:file on Ubuntu server, but can not run successfully on RHEL server. the error jus like: Loading: Failed. Could not load RHEL:a.bin: I/O error but I can login through "tftp RHEL", then "get a.bin". Does anyone know there is any other setting to open or restrict tftp service on RHEL ? I already disable firewall on RHEL.
