Re: conversion

[Julian Elischer]

The Bios of the Interjet was never tested or compiled with Microsoft in
mind. it is specifically tailored to boot FreeBSD with some special
hacks to support the LCD on COM2 (or was that com1?)
it is a 133MHz (or was that 233?) MHz chip for crying out aloud.
why on EARTH would you wnat to run windows on it?
(not to mention that it only has 32 MB of ram.)

You cannot get access to the exisiting FreeBSD because it is hacked too
much. The binaries are altered to use a database for many things FreeBSd
uses flat files for.

but the following should work for you:

install the drive on a regular PC.
install FreeBSD 4.6 from scratch.
Set it to have a console on COM1
reinstall it on the machine
log in on the serial port..
You should now have a standard FreeBSD machine with serial console
COM2 at (hmm I forget the exact baud rate) should print to the LCD.

conversion

[JM]

Anyone know how to convert an interjet to run windows 98??  or at least
to get root access on the exisiting freebsd?

I have a Whistle Interjet 200 server.  I am looking into converting this
over to windows 98, but one problem, the Interjet has a special bios. If
I install windows 98 on the HD, then it won't boot.  Other than the
special bios, the interjet is made out of a "single board computer",
which is a motherboard packed on a half size ISA card.  Do you know
anything about Interets?  Can they be converted to windows just by
changing the bios chip? or is there something else that has to be done?

Sorry, you did ask a specific question.  No, I hadn't tried those

That it might be. :/  Again, thanks for the advice...

If these are in ISA PCMCIA adapters, then the ping times seem very
reasonable to me.  And even if they aren't, my laptop -> Lucent AP ->
desktop has a ping time of 2.6ms - 2.7ms (my signal quality is 29 at
the moment).

Also, before blaming netgraph, which may well be to blame, could it be
that you have interference from some other source that's making things
bad?  The exactly every other packet being dropped does seem to be a
big clue.

Also, if you set things up to be a routing situation (for experimental
purposes), does the problem go away?

I am using a multilink connection between a fileserver and a switch, and it
works fine.  This is with regular 100Mbit ethernet cards.  On one occasion I
unplugged the "secondary" NIC from the switch without undoing the one2many
setup.  And every other packet to the machine was dropped.  I saw the same
thing you were seeing with your pings.

So.. I would think that netgraph is doing its thing, distributing packets
evenly between your two interfaces, but that one of the interfaces isn't
behaving.  My one2many script is essentially the same as yours except for
the order.  I don't know if it makes a difference (it _shouldn't_), but in
my script I bring the secondary interface up before doing anything else (and
then I load the ng_ether and ng_one2many modules, but I assume you're doing
that elsewhere).

I don't know a great deal about any of this, but I thought this might give
you a clue as to what to look for.

Good luck,

JN

multi-link 802.11b through netgraph yields poor performance.

[John Kozubik]

Julian, Archie, et al,

I have experimented with a multi-link 802.11b connection between two
laptops.  Both are 4.5-RELEASE, one has two aironet LMC352 cards, and one
has two Lucent gold cards.

I have successfully used ng_one2many, etc., to establish a working
multi-link between the two systems - however, I would appreciate any
comments regarding the very poor performance I see when networked in this
manner.

The problem I see is that, when using `ping` on either machine, exactly
every other packet is dropped.  After running `ping` for many minutes,
trying it from both machines, it is clear that _exactly_ every other
packet is dropped.  Further, echo response time is between 2.2 and 2.5
milliseconds, which seems very high.

I have configured the multi-link using the examples found in the
ng_one2many(4) man page - the only difference is that I have only two
cards in each machine, so in addition to running fewer `ngctl` commands, I
also had fewer links in my setconfig msg ([ 1 1 ] instead of [ 1 1 1 1 ]).

`ngctl list` on both machines yields this (seemingly correct) information:

There are 4 total nodes:
  Name: ngctl338Type: socketID: 0013Num hooks: 0
  Name:Type: one2many  ID: 0009Num hooks: 3
  Name: an1 Type: ether ID: 0002Num hooks: 1
  Name: an0 Type: ether ID: 0001Num hooks: 2

Finally, I should point out that one card in each machine is on channel 1,
and one card in each machine is on channel 11 - thus there are two card
pairs crossing each machine and each card pair shares not only a
frequency/channel, but also a SSID.  The purely wireless networking
portion of this experiment seems to be correct.  (I posted a few weeks ago
to freebsd-mobile a correct mechanism to get wi cards talking to an cards
in ad-hoc mode).

Theoretically interference should not be an issue as I am using channels 1
and 11.  The behavior does not change regardless of how close the two
laptops are or what their relative vertical/horizontal orientation is
... moving around the external antennas attached to the LMC352s has no
effect.

Therefore, since the every other packet echo response and the high latency
continues without missing a beat regardless of what I do to try to affect
the interference (if any) I must conclude that I am witnessing either:

a) a problem in the wireless drivers that causes them to be confused when
two of the same card is configured in the system using different
frequencies or SSIDs

b) a problem or misconfiguration on my part in the netgraph configuration

---

(a) seems unlikely as I feel that unspecific "issues" with the wireless
drivers would cause effects that were less regular than "drop exactly
every other packet".

However (b) also seems unlikely - if I had misconfigured netgraph and
ng_one2many, it seems unlikely that this would work at all.  It's possible
that my netgraph configuration is not even being used, and that an0 is
simply talking to wi0 over a non-multi-link, and that everything else that
is going on just happens to cause problems for that normal ad-hoc, one
card to one card operation.  However, my netgraph commands you will see
below, and the output of my `ngctl list` commands suggest that netgraph is
configured correctly.

Here are the network and netgraph related commands I entered, in order:

On machine A:

ifconfig an0 10.10.10.10 netmask 255.255.255.0
ngctl mkpeer an0: one2many upper one
ngctl connect an0: an0:upper lower many0
ngctl connect an1: an0:upper lower many1
ifconfig an1 up
ngctl msg an1: setpromisc 1
ngctl msg an1: setautosrc 0
ngctl msg an0:upper setconfig "{ xmitAlg=1 failAlg=1 enabledLinks=[ 1 1 ]
}"


On machine B:

ifconfig wi0 10.10.10.20 netmask 255.255.255.0
ngctl mkpeer wi0: one2many upper one
ngctl connect wi0: wi0:upper lower many0
ngctl connect wi1: wi0:upper lower many1
ifconfig wi1 up
ngctl msg wi1: setpromisc 1
ngctl msg wi1: setautosrc 0
ngctl msg wi0:upper setconfig "{ xmitAlg=1 failAlg=1 enabledLinks=[ 1 1 ]
}"



Any comments as to why the problems I am seeing (half of packets dropped
and high latency) exist are appreciated.
