Yup, the util's still on my web page, tho it's probably bit-rotted to hell by now. :) I know it's broken for flashing 486 NMCs right now. It also only works on Unix as-is, because it does a system() call to the tftp binary directly. (And tftp thru a firewall really is asking for trouble, because of the random port number issue.)

Yeah, I started seeing all sorts of random ports being hit, so I just opened up all tcp/udp between the tch and laptop. Now it went ahead and erased flash, then crapped out. Just sitting there. Nothing in the firewall logs showing what's up, and it's real addresses behind the fw, no nat.
I like "copy tftp://some.server/path/to/code slot0:" much better :)
There is a sort of minimalist beauty to it, isn't there? ;)
What type card are you upgrading? (I don't remember if you stated this in your original message)...
If its a .sdl/.nac file combo, then the sdl file is downloaded before the erasing of flash occurs, so you have another problem than tftp being blocked. If its a .dmf file type (ie, the newer HiPer type cards), then they just download in one go, but I don't think they erase flash do they? Now I don't remember.
If its the older .sdl/.nac combo, then there is two steps, you download the .sdl, then it erases flash, then you have to tell the NMC to download the nac file in another SNMP operation if I remember correctly. Again, the release notes for some of the later software releases I believe details the operations...its been so long since I've done this, and I don't know that I've ever done it fully manually, that I'm a bit fuzzy on it.
I seem to remember that Mike Andrews had a utility that did software upgrades on cards as well...are you still on the list Mike?
