Node Maintenance/ few questions

Rich Ball
 

I just got my node up this week and have a few questions as I get my
feet wet with Linux..

What is required for periodic node maintence such as deleting any log
files or view any error files??

Are there any documents that describe this?

Is the a list of command that can be run from the console other than
the short list in the setup instructions?

Any suggested reading for becoming familiar with Linux?

Thanks.......

You can add the following line to your Custom_decode file located
in the home/irlp/custom folder

if [ "$1" = "73" ] ;then "$SCRIPT"/end ; exit 1 ; fi

This will allow you to drop the connection to any node or ref with 73

You can use any set of numbers for this option as it uses the end
call script!

Hi Alan,

You can drop any connection with a 1111 .

All,

Is there a command that will end the link without
having to specify
the node number. If I'm connected to say node 327
instead of having
to know that, how can I just disconnect? Or better,
let's say
someone is connected to me and I don't know what the
node # is. Is
there a command to disconnect?

Is there a command that will just simply echo the
voice ID of the
node that is connected to my node?

Thanks,
Alan

Que puts out a book callUsing Linux which has been quite helpful
with the Amherst node. You can find more info on this book from
http://www.quecorp.com or can find it using ISBN 0-7897-1623-2

WARNING: Don't "play" with the IRLP box as user "root"

I'd suggest if you to learn about linux install it on another box and
play with it there.

/var/log holds your log files. I use "less <filename>"

You should not have to delete any logs in the /var/log dir as these are
handled by cron and logrotate.

Are there any documents that describe this?
yes
man cron
man logrotate


Is the a list of command that can be run from the console other than
the short list in the setup instructions?
Press the TAB key twice. :-) ...but an easier way for each letter

Press the letter "A" then hit the "tab" key twice, then "a" and again
the "tab" twice. Do this for all letters of tha alphabet.

The contents of /bin /sbin /usr/bin /usr/sbin generally contain
all the commands.


For info on any specific command man <cmdname>
For searching for info on any subject man -k <subject>


Any suggested reading for becoming familiar with Linux?
Search the net for Linux Documentation Project.

I use http://www.linux.org.au/LDP/

http://www.free-ed.net has a free online course available, The course ID
is OpSys123


Enjoy! Ron

I saw some of the other replies and would just add, "The Purple Book" --
actually called Unix System Administration Handbook by Evi Nemeth as an
EXCELLENT Unix resource (and has been for many many years)... now covers
differences between Linux, Sun Solaris, HP-UX, and BSD Unix as they come
along in the chapters on various system administration topics.

ISBN: 0130206016
Publisher: Prentice-Hall

Make sure you get the 3rd Edition, in the purple cover. Everyone used
to call this book the "Red Book", after IBM's old system manuals and the
color of the 2nd Ed. cover.

It's not an inexpensive book... but if you're REALLY interested in
having a great all-around Unix reference, this is it.

Well I do remember once logging onto my box as root, not paying
attention and doing the "olle" rm -rf * in the / directory

boy was I happy :-))

You may want to consider subscribing to a LUG (Linux Users Group)
email reflector. Not all of the traffic will be relevant to what you
want, but it's a good way to eavesdrop and learn from others of all
skill levels. IRLP-related questions are probably best posted to
irlp@yahoogroups, but general linux questions are perfect for a LUG
reflector.

The LUG at North Carolina State University has a reflector that's open
to the general public. For more info see
http://linux.ncsu.edu/lug/mailing-lists.html

Node maintenance

Valentino Sarro <ve6szr@...>
 

There was a question concerning "deleting" log files etc.. on the node
machine.

The answers received thus far only mentioned the general Linux logs
located in /var/log, however there are also logs that are maintained for
Node operation as well. Dave's programming includes a built in
log-rotation so you don't have to go "maintaining" anything.

Re: Dallas ???

Christopher W. Boone <cboone@...>
 

Dallas is offline right now....there have been some issues with
technical problems on the downlink xmtr from the site to the Net PC..
also the antennas are being moved for the link at the rptr end.....
415 is the node number...but it will be down for right now TFN...
hopefully not for long!

I did just rm -rf in '/' on a box once. Was lucky that I had a backup copy of the root directory on another partition. :)


Echo Reflector Problems

Jeff Young <kb3hf@...>
 

Gentlemen:
 
I have re-enabled my node 444 even though my cable modem is still being pounded with Port 80 probes from a gazillion different IP addresses. When connecting to the echo reflector for testing, I get echoes and delay/missing voice information. Is this still a traffic problem with red code occupying bandwidth on my connection?

Re: Echo Reflector Problems

Corey Dean KF3DY <kf3dy@...>
 

Jeff,
    There is an article on www.linuxsecurity.com about it this morning.  Yes, you are still getting pounded. Here is the title of the thing "Apache CodeRed Countermeasures with PHP: codeRedKiller!"
 
Here is the URL.  Please let me know if this help....

telnet client for Windows

el1ggc
 

Hi all,
Does anyone know if a telnet client exists for Windows, to enable one
to minitor the voice ip traffic of a node remotely? I know DC
mentioned this a while back, whereby a password protected login to a
node would enable something like this? I know we have had streaming
audio using a Real Audio server, but this facility is something
else...

Audio setup - not trying to start WWIII :)

ne1h@...
 

Ok,

So, I have been pulling my hair out trying to get my audio levels set
correctly. I decided to get scientific about it and maybe that is
where I should have stopped.

Here is what I have done so far.

a) I play the audiotest file and with a service monitor connected to
my link radio, I setup for 4khz of deviation

b) Then I connect to the echo reflector and adjust RX (input) levels
on the soundcard with a 3khz deviation 1khz note tone, so that I get
3khz of deviation back from the reflector.

c) I then checked the 1khz - 4khz of deviation in 1khz steps and it
was pretty linear.

So, this morning, I connected to a node and they said my levels to
them were low and their levels to me were really HOT.

So I give up.

Someone give me a foolproof baseline method???

The way, this really should be done is as follows.

a) play audiotest and adjust for 4khz
b) get someone to do the same on their end of a link
c) generate a 1khz tone, 3khz dev signal on my end of the link and
I'll adjust my input to the soundcard until you have 3khz of
deviation on the other end
d) now they do the same while I tell them what the deviation is

That's how you get a real scientific approach. Course you should do
it for ever 1khz of deviation up to 5 and you should really do it for
ever 500hz of tone from 500hz - 3.5khz.

The system should be linear and it should reproduce somewhat linear
results (it is a lossy compression schema, so it will never be
prefect)

But I don't want to go there now, I want to get something that sounds
resonsable for now....

Any help or process solicited,
Alan


Re: telnet client for Windows

ne1h@...
 

I may have misunderstood your question.

Telnet is for login to a host that will accept telnet connections.
Monitoring your audio is something entirely different and I know of
no way to monitor the voip traffic on you node remotely.

What are you trying to do exactly? Maybe if you are more specific,
that will help.

Dave had planned to give us a way to telnet in with a user name and password
that would allow us to actually connect to the node and use it as if we were
on a radio. Shortly after there was a security problem with telneting and
Dave decided it was a bad idea. The project was halted until a better way
can be created.

Yes, Glen
That's what I was thinking of...so it must be possible to transfer
voice ip thru a telnet type link using a suitable client?

Apparently so, but I can not tell you how to do it. I believe Dave and maybe
one or tow others have it but it was not distributed.
