- This sounds exactly like a problem I used to have. The ethernet driver
- on my 720/730s stopped accepting packets greater than 80 bytes (ping works,
- ftp doesn't!) after it received an ethernet packet greater than 2096 bytes.
- Note that the maximum legal ethernet packet size is 1514 bytes. But
- some manufacturers of ethernet devices don't seem to take that limitation
- too seriously. HP has a patch for this (PHNE_0469 on the 700 series, may be
- the same on the 800s).

-
- Yup, a reboot fixes it (until the next killer packet). BTW, so will
- resetting the ethernet driver.
