Is there anything in UBCD that you can boot into and create a TFTP server? I searched the forums and I think I found a few threads that would let you use UBCD as a PXE bootloader, (and boot and image hosted elsewhere) but that's not what I'm after.
I want to stick my read-only flash drive (w/ UBCD on it) into my laptop, boot something, stick in another flash drive with the boot images on it. Plug a cable in between my ethernet port and the router/embedded device/whatever, and then either allow an IP address to be assigned (DHCP) or setup simple 2-node networking with whatever static IP address the embedded thingy was expecting.
Then of course, I want to flash the router/embedded thingy.
If not, any suggestions for tools to investigate/tweek/modify? I'm looking into puppy linux. I'm also willing to customize a distro if that's what it takes. Would consider anything but prefer FOSS
I spent a bit of time investigating Freesco, but damn if I'm having a time figuring out how to add it to UBCD. I know it has pre-made package that will let it do TFTP, but you would not believe what compromises they take to make sure the distro will still run on a floppy-only 286.
You could try Slax, it is small, will run from UBCD and there is an add on package that provides tftp.http://www.slax.org/
