This is likely more a "slug" problem than an OpenWrt problem, but here goes...
I've loaded my NSLU2 "slug" with OpenWRT Kamikaze (7.07) from the slogos firmware downloads page, and I can't update the darn thing through "ipkg update" because wget always says something about a bad content length.

The slug behaves the same way with OpenSlug (SlogOS/BE) loaded on it, this is after a complete flash erase via redboot.

Any guess as to what I'm doing wrong? Sorry such a NOOB question.
