I have the belkin omniview, and experienced the same problems.
AFAIK this is because of the following two potential reasons. The
intellimouse uses all 8 pins of the connector wheras most mice use only
7. *Manual* switch boxes seldom switch the eighth, and thus do not
support the intellimouse. Further, the intellimouse uses a bidirectional
protocol, and it requires itself to be permanently connected to the
computer using a protocol which is slightly different to other mice.
Thus, when you switch the mouse away from the linux box (or the other
machine), the omniview does not respond correctly with the "dummy" mouse
responses. Thus, the protocol is "broken". In Win98 this is symptomised
by a few seconds where the mouse "catches up" with itself (which is
annoying but manageable), and in Linux it is revealed as jerkiness, and
the buttons don't work properly, etc. (The cursor for me used to end up
in the top right of the screen). This reaction is documented in the
omniview manual.
The solution - get another mouse ;-)
I have heard that it is possible to fix it some way, I think by using
gpm to feed the X server instead of the X server using it's own driver.
I am unsure of whether this works. It will be pointless (no pun
intended) anyway if you get the same effect when you are at a console
terminal session.
So, in desperation I bought another mouse, except I have limited desk
space, so I bought a trackball (logitech). Thus, my omniview only
switches the monitor and keyboard.
That was my fix.
I am unhappy anyway with the quality of the image , so I am still unsure
of whether the idea is OK. I think I just need a bigger home with more
desk space to fill with more computers ;-)
cheers
gus
P.S. FWIW, X does support the wheel .... I have the intellimouse driving
the linux box and the trackball on the Win98 machine.

you need a packet filtering firewall.
see, e.g., <URL:http://rlz.mediaone.net>.
i got his ipchains firewall script (since i am using 2.2.x kernels).
he has an ipfwadm version too. you will need to do a bit of manual
tweaking, but the script is extremely well laid out and well
commented.
he's also got some sort of cgi firewall-o-matic but i never figured
out how work it (besides i already had a working firewall script and
didn't need a new one).
hope this helps.

Better check Belkin, but I don't think the OmniView supports the
Intellimouse. I think you need the new OmniCube. Also, I couldn't
get my Intellimouse (configured as an Intellimouse) to work under
Linux (Red Hat 5.2). The pointer would just go whereever it wanted.
Selecting "Generic PS/2 mouse" corrected the problem. Linux doesn't
support the wheel yet anyway, so it didn't matter to me.
If those two check out as not the answer, this might help.
I recently bought an OmniCube switch. It has an option to use the
<Scroll Lock> key to switch via the keyboard, rather than by the
button. I don't know if the OmniView has this feature, but I know
that sometimes the <Scroll Lock> will freeze the mouse/keyboard in
Linux (imagine that - Scroll Lock actually working as it should).
Pressing Scroll Lock again fixes the problem.
Hope this helps.

I don't know about it not making sense as I have used it before. I
sometimes compile certain programs to run on a multiprocessor machine
and a single processor. Some file need to be changed, others don't. I
use defines to compile the same file for both situations and use the the
-o flag to give them different names. For example, I might have the
following lines in my Makefile
prog: a.o b.o
cc -o prog a.o b.o
smp_prog: a_smp.o b.o
cc -o smp_prog a_smp.o b.o
a_smp.o: a.c
cc -c -o a_smp.o -DSMP a.c
a.o: a.c
cc -c a.c
I can choose to compile either version of the program.

That one isn't standard.
It is probably for a network game server.

Correct. So the nameserver needs to talk to my computer to know what
my computer is called. And this was the initial question I had.
But as far as I learned till now, this is not possible. I cannot
communicate to the DNS server to tell him that today, my computer
(let's call him 'foobar') has IP 1.1.1.1 and that tomorrow 'foobar' is
hooked up under IP 1.1.1.2.
This doesn't work apparently.
I guess I have to take the work-around solution with the web page.
Anyway, thanks a lot to all who replied.

if your kernel source is in /usr/src, put the patch in /usr/src, and run:

Subject: switching intellimouse between Linux/X and NT
Date: Thu, 11 Mar 1999 23:08:52 -0500
Hello,
I have an OmniView switching between two systems; NT 4.0 Server and Linux
5.2 with a Microsoft PS2 Intellimouse. The mouse stops working when I
switch from NT back to Linux/X. Restarting X corrects the problem. I was
hoping that someone had some insight on how to correct this. I'm guessing
that this problem is caused by some mouse initialization code in NT that
prevents proper operation when switching back to Linux/X.

You didn't indicate whether your US Robotics 56 was a WINMODEM or not. If
so, go buy another one that's not a WINMODEM. Also look at the man pages
for the statserial command. That may give you some insight as to whether or
not you're actually communicating with your modem.
As for SAMBA, there's a great book out for it that I'd wholeheartedly
recommend getting. I forget its name but I've got it on my site at

Subject: LINUX SOUND III SYSTEM -- Please help!
Date: Fri, 12 Mar 1999 19:22:30 GMT
Dear friends:
Well, everything seems to be ready for my Linux, which will arive next week
EXCEPT for the matter of SOUND.
I just discussed this problem extensively with a technician at AztechLabs,
which makes the Sound III system that came with my NEC Pentium 166 MMMX OEM
and Win95B, 64 meg RAM. 33.3 modem and ADSL Ethercard.
Thank to his kind help, I now know exactly where I stand, but I do not have
a solution for it as yet.
In a nutshell, AztechLabs, being mainly a supplier of sounds systems to
OEMs running Windows, does not as yet have a driver for Linux. He urged me
to contact the Linux community for help.
Here are the precise specs:
My sound/modem system (FCC-ID MMSN 855) is called Sound III. Its generic
model no. MMAT-3500 and its generic drivers (both are required) are: MAT-35
(U1nd U2). These two drivers run my entire sound system.
May I kindly ask if any of you Linux users out there have a similar system
or have had to deal with this particular sound system or might have a
solution? It would be much appreciated.
I have been reading and preparing hard for this exciting transition to
Linux, to putting behind me the two years of agony of fighting a losing
battle with Micro$oft's toys. This may be my last outstanding problem. My
ATI video card is fine, my GoldStar Cd should be fine, my Epson printer
should make it fine, even my 3Com ADSL driver should make it, but this
Sound III problem concerns me deeply.
Is there a solution?
Thank you all so very much. You have all been just great!
Yours,

Reply-To: [EMAIL PROTECTED]
At work I got a NT server and an experimental RH 5.2 server. The RH box
is working as a client. The NT server works as a DHCP/DNS server. Do not
ask me for the reason, it just have to be that way. It's not within my
control. What I want is that the RH box should work as a DHCP client
from which I can do some stuff.
I've set the RH up as a DHCP client and I feel that I have done it
right. However the linux box tries to get an ip which it shouldn't. We
got a DHCP client ip range which goes from x.x.x.71-x.x.x.98. When linux
tries to get the ip it _always_ tries to get x.x.x.72 and want accept
any other ip's. Why?
Any help is appreciated.

Hi ,
What problems do you have connecting to your ISP ?
PPP is really quite simple and you shouldn't have much trouble.
The thing is there are a few things to know and if you don't know, well
you
don't know.
With regards to glint, what are you doing when you get that message ?
Installing packages or just seeing what is on your system ?
Glint needs to know where to look for the packages if you are
trying to install : hence the procedure as follows => mount
/dev/cdrom
configure (glint menu)
/mnt/cdrom/REDHAT/RPMS (or wherever your
packages are)
Available (glint menu, this scans the selected
directory for packages.
All filesystems have to be mounted in Linux, that includes things like
drives.
Hope this helps you and isn't redundant to your knowledge.

A few easy ones
(1) If I 'cat' a binary file by mistake, I often end up with a garbaged
system - all messages and prompts are translated into Klingon - or
something like it. How do I recover without rebooting? Even exit
doesn't fix it.
(2) I've set up Samba and it works fine, but I have to start it
manually every time I log on? Where should I put the "smb start"
command? (SuSE 6.0)
(3) I have a vfat disk mounted, but can't write to it, except as root.
Somebody suggested that I specify 'user' in /etc/fstab, and that sort of
works - if I umount and mount it again, I can write to it, but how can I
avoid the need to do that?
(4) I've got a Freeserve connection working, and I can browse the web
to my heart's content, but I'd like to do email and news too. The SuSE
chapter of sendmail seems awfully complicated - do I really have to go
through all that?
