How about looking at the Arduino controller board and motor control 
board (low cost), you can do Steeper Motor and DC motor control, all 
control software libraries available for free.  Manysizes/flavours of 
Arduino controllers and add on boards/shields depending on what you want 
for price/features

Before mail ordering, you might try asking at Active Components on Century
St.. They have lots of hobby micro stuff.

I am also trying to set up ssh. I installed OpenSSH on Ubuntu server, and
downloaded WinSCP for my Windows computer. Both machines are in my home
office right now, but the server will be relocated to a business office. I
will continue to administer the server so want access from my home office. I
need the server to be secure, so I want to use key authentication. My client
machine is Windows so I can't run ssh-copy-id, so I just copied the .pub
file to the server then copied it to authorized_keys. It's rejecting my key.
I have passwords enabled for testing, but want to disable passwords when I
actually connect through the internet. I tried to have WinSCP generate the
keys and copy the .pub file to the server, and I generated keys on the
server and copied the private key to my Windows desktop. WinSCP requires
"importing" the private key, it adds some of it's own stuff such as the
client's MAC address. Either way the server just rejects the key.

I have ensured PubkeyAuthentication is yes, AuthoriedKeysFile is
uncommented, and issued the ssh restart command after each change to the
server's config file.

What am I doing wrong?

Rob,

Is the Ubuntu server "rejecting your key" during the SSH login session? Are
there any logs available from either WinSCP or from the SSH server? I think
SSHD can provide some verbose real-time logging which might detail the
error. Are trying to login as root when testing the keyed & password based
logins?

Sorry that's all questions & no answers but maybe some part of it will point
you in the right direction.

Kelly

My two cents.

Sometimes the key that is generated on Windows machines is malformed
as far as openssh is concerned. Make sure your authorized_keys entry
looks like this

ssh-rsa AAAAB3Nz(snip)KZbC1PEWyI4Q4esMJogfsWpXnB8Q== CommentAboutTheKey

I've used putty with it's key store 'pageant' with quite some success.
 It's a background application that does the key auth for you.  You
decrypt your key once (your private key is _should_ be encrypted....
) and it happily does nothing most the time. I think putty prompts you
for your key, but I seem to remember it having mixed success.

Hope that sheds some light on the situation.

I've had a similar problem because I wasn't thinking and didn't restart 
the ssh daemon. ( on ubuntu its invoke-rc.d ssh restart ).

Have you tried puttygen? (same place you get putty)

It'll load or generate a putty keypair.When you have a keypair loaded, it
shows you the exact string you will paste into authorized_keys on the
server.

Message-ID: <201005041724.o44HOxJ14493@iron.cs.umanitoba.ca>

The Manitoba UNIX User Group (MUUG) will be holding its next monthly
meeting on Tuesday, May 11.  The meeting topic for this month is
as follows:

   Podcasting

   Podcasting lets you share your thoughts with the world through an
   audio subscription model. How would you plan and organize a podcast
   of your own? What tools should you use to record, edit and encode
   your podcast? What distribution tools are used? How much does it
   cost  to podcast? Can you use free or open source software for
   podcasting? MUUG member Brian Doob has been podcasting for three
   years and will answer these and many other questions.

The group holds its general meetings at 7:30pm on the second Tuesday of
every month from September to June.  (There are no meetings in July and
August.) Meetings are open to the general public; you don't have to be a
MUUG member to attend.

   **********************************************************************
   Please note our meeting location: The IBM offices, at 400 Ellice Ave.
   (between Edmonton and Kennedy). When you arrive, you will have to
   sign in at the reception desk, and then wait for someone to take you
   (in groups) to the meeting room. Please try to arrive by about 7:15pm, 
   so the meeting can start promptly at 7:30pm. Don't be late, or you may
   not get in.  (But don't come too early either, since security may not
   be there to let you in before 7:15 or so.) Non-members may be required
   to show photo ID at the security desk.

   Limited parking is available for free on the street, either on Ellice
   Ave. or on some of the intersecting streets. Indoor parking is also
   available nearby, at Portage Place, for $5.00 for the evening. Bicycle
   parking is available in a bike rack under video surveillance located
   behind the building on Webb Place.

Anyone know of any decent place to find a replacement PSU for a Shuttle box.
PSU part number is PC35I2402.

It is probably not worth replacing though if there are 'off brand' options I wouldn't mind knowing a few places to search.

I've seen Micro-ATX SFF power supplies at itech and CBIT, pictures 
below. From Google that
shuttle model seems to be a custom size and hard/expensive to get, so if 
a Micro-ATX PSU can
be fit nicely in the case it may be preferable.

Alternately, you can just use any old ATX power supply, with some creative use of strapping and duct tape.  And that PSU would likely last a lot longer than the SFF version in a shuttle.  (Usually quieter, too.  Albeit much uglier.)

You're invited to join us in Boston, June 23-24, 2010, for the first
USENIX Conference on Web Application Development. WebApps '10 is a new
technical conference designed to bring together experts in all aspects
of developing and deploying Web applications.

Web-based applications are revolutionizing both the features that can be
delivered and the technologies for developing and deploying
applications. They also involve a diverse collection of issues and
technologies. Take advantage of this new opportunity for interaction and
synergy across these areas.

The program includes:

* Invited talks by industry leaders including Adam de Boor, Google, on
"Gmail: Past, Present, and Future"

* Refereed papers on a variety of topics such as new approaches to
Web frameworks, techniques for giving users control over their Web
data, better ways of managing Ajax and Javascript, and a variety
of security issues ranging from better CAPTCHAs to information flow
tracking.

* A Poster Session and Happy Hour held jointly with USENIX ATC '10.
The poster session provides a great way to let other people know about
your work and to get useful feedback from the community. Submissions are
due on June 13, 2010.

* Work-in-Progress Reports. If you have work you would like to share, a
controversial opinion, or a cool idea that's not quite ready for
publication, submit a WiP by June 13, 2010.

Find out more about the posters and WiPs at:
http://www.usenix.org/events/webapps10/posters_wips.html

WebApps '10 is part of the USENIX Federated Conferences Week. Not only
do you get a 2-day conference program filled with the latest research,
but you'll also have additional opportunities to mingle with colleagues
and leading experts in the combined Birds-of-a-Feather sessions (BoFs)

Subject: [RndTbl] DNS Ubuntu
In-Reply-To: <4BF6E055.5020406@cs.umanitoba.ca>
Message-ID: <000201cb0113$83e4afc0$6400a8c0@wp.shawcable.net>

Could I ask for help configuring DNS?

I am trying to setup an webserver using Ubuntu 9.10 Server, Karmic Koala. I
have it setup in my home office behind a D-Link router. I installed DNS
server, LAMP, email server, and Tomcat. To get familiar with configuring
DNS, I attempted to simply setup a DNS as both a caching server and create a
master entry to point to a website on itself. I called the website
"example.ca". The D-Link router acts as a firewall so it shouldn't
propagate. But it isn't working, when I use "nslookup example.ca" the
response is "*** Can't find example.ca: No answer". When I try "ping
example.ca" the response is "unknown host example.ca". What did I do wrong?
I changed "/etc/resolv.conf" to have the IP address of my server instead of
the router or my ISP, although the domain and search are still my ISP. I
ensured the "forwarders" address in "named.conf.options" is my router. I did
restart the DNS service after each change. Bit it still isn't working; I can
lookup any address from the internet but my own server does not resolve. I
followed these instructions:

https://help.ubuntu.com/10.04/serverguide/C/dns-configuration.html

Did you create a zone entry in named.conf and the associated zone file?

zone "example.ca" {
 type master;
 file "example.ca.db";
};

example.ca.db:
  IN A 192.168.1.1

When you restart named, always look in the logs (/var/log/messages on most
systems) to see if any zones got turfed. If you make a mistake, named will
not load the zone, but will happily continue on with the next zone.

Does your forwarder work? eg can you nslookup cisco.com @localhost ? Is
named bound to all the interfaces?

BTW, if you're just trying to get example.ca working for development, the
fastest way is to edit your hosts file(s) and skip DNS entirely. DNS takes a
few "oops" moments to understand, and is often best skipped if possible.

Thanks Sean. For some reason my server does respond to www.example.ca but
not to example.ca

Of course the point is to learn how to configure DNS, and to start
configuring this server for use on the web.

If it answers for www.example.ca but not example.ca, then you haven't
configured your zone for the latter:

www IN A 192.168.1.1  ; www.example.ca
         IN A 192.168.1.1 ; example.ca
foo.bar IN A 192.168.1.1 ; foo.bar.example.ca

All the names on the left hand side are relative to the domain, including
"nothing" which means the domain itself.

I am considering adding eSATA and external toasters to my Mac Pro, in order to maximize swapability but maintain speed.  I am thinking of making my next machine entirely eSATA / toasters, with no internal drives.

Is there any major downside to doing this?  I am assuming that I can hot swap on any *nix system (aside from the boot drive) and that the speed will be only minimally slower than internal SATA, and still faster than my drives.  I am assuming that the drives will run quietly and cool in toasters, and that my cat won't chew the cables.

Am I missing any obvious problems here?

The eSATA speed should, all other things being equal, be identical to internal SATA.

Beware that unless your ports are explicitly eSATA, they likely won't handle hot plugging properly.  (i.e. You can connect your onboard SATA ports to eSATA adapter brackets - and this will generally work - but they don't magically support all the "e" aspects unless designed to do so; some are, some aren't.)

Also if you want to use any kind of multi-bay enclosure, the host ports must explicitly support SATA Multipliers (multiplexers?) or you won't be able to access any of the drives in that enclosure reliably.
