At the bottom of the ENVIRONMENT section of 'man ssh':

Additionally, ssh reads $HOME/.ssh/environment, and adds lines of the
format ``VARNAME=value'' to the environment if the file exists and if
users are allowed to change their environment.  For more information, 
see the PermitUserEnvironment option in sshd_config(5).

[OT] SGI supercomputer

Gee! For a current bid price of $500 it's a steal. Too bad the AC power
will cost $1k/month to run the pile.

Heck, it will cost double that to move the stuff to another location.

  Hell, that's newer than the Challenge XL's we used to run the FSN in
'93.

I did development on a sgi origin 2000 in college.  It was not as big
as this one, but it was a real nice box to write code on.  They have
an internal hypercube type network that just screams pushing data
around.  I had a hyper-quicksort implemented that achieved nearly
linear speed increases on something like a 4G dataset (64bit floats)
in memory.

ALE NE Tomorrow

Marc Torres will be unable to present tomorrow at ALE:NE due to work
commitments in Houston. Since I was planning on doing the same
presentation for ALE-Central I'll be presenting tomorrow. Marc will be
presenting next week.

Unless people want to cancel, which would be fine by me.

[OT] An "On The Air" (Literally) Video Display System

I just received an interesting product announcement in an Amiga
email newsletter I subscribe to.  If this device is for real (and it seems
that it might be) it is ULTRA UBER cool:

** 
A laser based display system that utilizes ambient room air as the
projection screen!  Interactive 'Air-Touch' interface feedback capability,
too.

http://www.io2technology.com/technology/images
http://www.io2technology.com/technology/overview
**

They are claiming Toyota and General Dynamics as customers 
who have used their prototype product already. On the other hand,
their "retail portal" link is currently a 404 bounce to a hosting advert.

If it turns out that this is just a hoax, it's a very imaginative one.

Re: [OT] SGI supercomputer

James,
You shouldn't have posted this.  I am all in a dither now.  I could use 
it since we have codes that only run on 64bit IRIX.  However, it's 
bulky, may or may not really operate, and the hardware support cost per 
year would be expensive.  I'm sure a SGI reseller will up the bidding 
near the close.  It's worth about $20K to someone who can use and 
support it.  Sometimes you need the hardware when the software isn't 
modifiable.

I'm going to go to bed now and forget about this.....

Thanks for the hints. I will put together a script to scan the network.
I think the script should do the following:

1. Set own IP-address. (x.x.x.1)
2. Use Nmap to scan the network. (x.x.x.2-254 in a class C network)
3. Stop and tell the user if a machine is found.
4. Set own IP-address. (x.x.x.2)
5. Use Nmap to scan the remaining address. (x.x.x.1)
6. Stop and tell the user if a machine is found.
7. Start from 1. again.

Did I miss something? Is there a smarter way to construct the script?

I have a machine and a crossover cable I'm gonna use. This negates the 
possibility of false hits.

Thanks again.

René
