When using the tftptool supplied on RH6.1 Sparc CD under /utils, with all the required information supplied on the command line, a "Name error" was generated for the name "x" On investigation I found that the error occurs on a line which says : type = x[1] I believe this line is mis-indented, and should be part of the "if" clause which immediately precedes it (which deals with the "snack" user interface and has the array 'x' defined). Sorry, but I'm not sat at the right machine at the moment, and I can't remember what line number this occurs on (it is also possible I have the capitalisation or even some other details wrong).
SPARC is not a supported architecture.
