I have a situation... My firewall/router, which has been running OpenWrt pretty happily, may be dying.

I've made some changes I'd like to keep, but otherwise I'm going to try and reflash with kamikaze.  The problem is that I can't get into the router any more via ssh; it doesn't respond to pings.  I can get it to respond in boot_wait though.

Before I wipe out the current image, can I use tftp to get a copy of the existing jffs partition, the one where my firewall script would be?

Thanks,
