datatransfer beside ethernet
here quick story:
got a PC with old system on-disk, but new motherboard -- with a not out-of-the-box network interface.
The Chip onboard was too new, not even in the (atm current) 2.26.30 kernel...
Good, the Vendor has some module to compile available.

now... I need to bring some stuff to the disk. (e.g. gcc, make, kernel-headers, ... )
I learned in this journey a lot of nice possibilities:

To note, the box had no space for a other card, not I had a usb-wlan stick around...

* "memstick" ( the usb thumb drive thing -- this includes a lot of walking ) -- fast (apt knows the --print-uri option, so you can wget them easy... but the dependencies makes you cry)
* running network over serial cable. ( slattatch is your friend ) -- very slow, did set it for 115k baud...
* network over blue-tooth (it worked one day in NAP mode, next day I had no luck to get it work again) -- should make up to 80k/s

This was the bad card:
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)

The driver to build is r8168.ko

The GRML (grml.org) live-CD had the driver in -- so a boot/mount/chroot trick makes it, too. (very handy !)
