I need to build a wireless ap with a hard drive in it... I want to
wirelessly ftp files to the hard drive and then have the box dial a modem to
send a signal to a central place to log the files that were stored
there........
can this be done with any soekris gear?
thanks

For what it's worth, standard POTS circuits are whatever DC volts it
takes to shove 60mA through a "standard" phone.

I think there is an upper bound on the voltage, probably about -52VDC
or whatever the float voltage is on the large stack of batteries used
to power the equipment.

Subject: [Soekris] net4801 and Routerboard 24 interrupt problem
Hi all,
We recently purchased a couple of 3.3v Mikrotik Routerboard 24 4-port
NICs. In a Soekris net4801 running Linux 2.4.25 and using the standard
in-kernel natsemi driver, the second and fourth ports on the Routerboard
don't generate interrupts when packets arrive. Packets are buffered, and
appear in the network stack only when the first or third interface
receives a packet and generates an interrupt.
If I leave a "ping" process running on another machine connected to the
Soekris' eth4 or eth6, nothing happens until I ping eth3 or eth5 from
another machine. Then I get a flurry of ICMP replies, and the interrupt
count goes up by only two.
I've tried two different Routerboards on two net4801s with the same
results. I tried going back to kernel 2.4.20 with the same result. I also
tried a couple of net4501s just in case, but couldn't get the interfaces
to come up: the Soekris assigned all the Routerboard NICs IRQ 0 (no IRQ?)
on boot.
I also tried on a recent PC running 2.4.24, in two configurations: all
Routerboard ports on different IRQs, and all ports on the same IRQ. It
worked as expected, so I think the problem is specific to the net4801.
The Soekris BIOS (1.23) reports the following PCI devices:

The bottom four lines, on IRQ 5, are the Routerboard, I think.
In Linux:

8: 0 XT-PIC rtc
10: 33 XT-PIC eth0, eth1, eth2
14: 11486 XT-PIC hd
NMI: 0
ERR: 0
I'm going to try adding a 100ms rx poll timer to the natsemi driver... not
pretty but it might work :)
Is there any way to change the way the net4801 assigns IRQs? If I could
force one or two of the ports to different IRQs, it might make for a
better workaround.
Thanks,
Mike

And that power is shoved several THOUSAND feet over different
types of cables that might come into your house.

My GirlF (bless her) bought me the new one since my other one was
from 1992 or so. I can amuse myself just skimming through it.
Airline reservation numbers, area codes, load bearing of joists
by size and length, melting tempurature of lots of things. Also
voltage drop by distance over different gauges of wire.
This one came from Ace Hardware. It's everywhere.
It's pocket sized.
The soekris will die on more than 56VDC over PoE. Your 26G solid
core cable will breakdown if you run 2000VDC over it with ground
adjacent, I'm sure. Wanna power that washing machine at 10Amps?
Don't use a network cable.
Wanna learn basic electronics? Books and google abound. DC is
really pretty easy.

Off hook, yes. But I said on hook. On hook, it floats to something
around 48VDC (plus or minus a few v depending on how the 4 car batteries
batteries & charger are feeling). It's not going to get any higher than
maybe 56v on hook, barring lightning strikes (and ring voltage).

the conexant bt878a which is used on maybe 80% of the consumer pci capture

around it.

Well, speaking from experience ONLY plug the poe injector into eth0. I
accidently plugged it into eth1 since I didn't know any better and was
greeted with a nice little orange flash and a puff of smoke.
I tested the port out, and somehow it still works for data even with the
burned out parts (which look like smd resistors or caps or something).
I guess I'm lucky, but I will never make the same mistake agtain.
Would be nice if the board designers would make some modifications so
that the poe could be plugged into either port.

Your network connection (Internet via DSL, etc) goes into J1 "Data only"
and your CAT5 connector from J2 "Data & Pwr" goes to eth0. Make sure you
*do not* plug into eth1. I have a 4521 with the power supply from Ault,
Inc. (says Ault, Inc on the instructions but says ITE on the power supply).
Hope this helps,

Is this using the Soekris PoE injector or some other injector?
The Soekris injector is advertised as 802.3af. It is not supposed to
detect legacy equipment or over-current?
