Re: [orca-list] Ot: does anyone have a certification from the Linux foundation?

Actually, these days as long as one has the moneyl to get a relatively good phone checking for what is and is 
not lit up may be doable using the phone's 
camera, and a light sensing ap. 
I do not know if apps exist that can tell you the color of an led or not, but they should if they do not. 
Of course simple stand alone light sensors have been on the market for years and can be built by anyone with 
a very basic understanding of how to 
connect electronic components.
I have heard that taking pics of a screen can give good enough input for OCR in many cases, but do not have a 
phone that can do this kind of thing at 
the moment due to lack of funds, but want to get one and see how good a job one can do reading things like 
bios screens, and error messages on screen 
when there is no speech.
Sighted help will usually be faster and easier, but there are certainly times when no one is around or 
available and it is nice to be able to continue 
work even if it is a bit of a pain.

Hi,
Years ago, I did the Redhat certified engineer exam, and over the
years have done a lot of sys admin work on unix and linux servers.
Here are a few comments.
1.  Do not expect to be able to work directly on the server with a
screen reader, make sure you have a good understanding of all the
remote access options available to you.
2.  As a blind person, make sure you understand how to do admin
without a GUI.  In the case of Linux, you can do most things without
a GUI and often, it is as simple as editing a configuration file
with a text editor.
3.  There are some situations where you will need sighted assistance.
Once, one disk in a raid configuration on a machine with a hardware
raid controller, went dead and although I could find some code
indicating which disk it was, the only way of knowing which physical
drive to take out of the machine was to look at the lights showing
up at the server itself.
I found that obtaining sighted assistance was easy enough once you
are trusted by your superiors to know what you are doing, as then,
you do not need a sighted person with knowledge.  A secretary can
tell you about the lights, or read you an error message just as well
as one of your sysadmin buddies.
HTH, Willem

Hi.

Wanted to chime in.  The posts on the mailing lists I have
frequented over the years from people who do sys admin work also
say they use ssh a lot with clients like Putty on Windows.  I'm
sure there are similar gui products with Orca on Linux that you
can use to connect a laptop to a remote server. There's always
just plain old ssh itself running Speakup locally through
something like a Gnu-Screen session too.  I understand there are
blind people who also used Emacspeak to do server sysadmin work.
I bring up remoting because so many servers have sound disabled
and I also understand that they may view Speakup as a security
vulnerability somehow. (Not sure about how that can be but, there
you go.)  So, it's important to get to know tools that let you
access a server remotely.  To Conclude, it is entirely feasible
for you as a blind person to do this kind of job.  Others have
done so before you and, if they could, you can.  Nuff said.  Good
luck and all the best!

No I do not have any Linux certs, but I will say that there is
no reason you cn not do a good job managing Linux servers using
speakup mostly, but
sometimes Orca as well.
All of the standard tools and utils I can think of work with
speakup, but some that stream realtime data are of course harder
to use as data is
constantly being updated.
When one must work with a tool like that you usually need to
either slow down refresh rates quite a bit, or take snapshots of
the system and use those.
Often something can be piped to a filtering application, awk,
sed, grep, etc to help by removing data one does not wish to
her. Also speakup lets you
block out parts of the screen in its read window mode so you can
get rid of some distrctions.
Of course to get a job and do it well you will need to be better
than your sighted counterparts, but is this not usually the cse
for anything we do?
We will be slower having to listen to things than a sighted
person will be reading it, so beiing better, i.e. cutting to the
heart of a problem, knowing
what to expect, etc. is of great importance when and where it is possible.
