I will make a stab at what you are really asking here.. but I could be wrong.
The file comes in what is lovingly referred to as a *tarball* by the Unix geeks. It's a something akin to a ZIP file but based in Unix. When you use the command 'tar /x tftp://server_ip..blah..blah' you are telling the switch (which runs a form of Unix..BSD???) to get the file X.tar via TFTP and then run the TAR command with the /x argument. This whole thing will grab the file, download it and then extract each piece of the tarball into the proper file/directory. The tarball doesnt care about the TFTP server as long as it supports long file names. So you have an NT box running an NT TFTP server.. no big deal. Everything works just fine since the TAR command runs on the switch and not on the NT box. I hope that is what you were asking about or I seriously misunderstood the question :) MikeS -- Tutorials - Whitepapers - Security - Wireless- News Find me at www-dot-packetattack-dot-com ""Sharon Kantan"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi..Gaz and dear all..
