redhat tftp server issue

[张廉]

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.

Thanks,
Best regards,
will
