Back Up Plan For San Migration. Lvmconvert--2 Leg Scenario.

I have a similar script as follows

Code:

(sleep 5m; echo "set_property volume 85 > "fifo_file")&

mplayer -volume 95 -quiet -slave -input file="fifo_file" song1 song2 song3

This makes the current song change volume to 85 after the 5 minute sleep period, but any songs after that revert to 95.

I want to keep it at volume 85 until the mplayer command completes but start at 95 until changed.

Is this possible?

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:

rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?

I have the below URL

http://linoxide.com/ubuntu-how-to/awstats/

in this URL , it have the command "sudo a2enmod cgi" to check the cgi is installed or not , but when I run it , it pops "bash: a2enmod: command not found" , I tried to install it by yum install a2enmod" , but got the below message , would advise how to install it .
Code:

Loaded plugins: fastestmirror

Hi!

Here is mine configuration and I want make it show unicode(russian) in console, it works perfect in X11 but not when I logging into tty.

vconsole.conf
Code:

LOCALE="en_US.UTF-8"
KEYMAP="sv-latin1"
FONT_UNIMAP="lat1"
FONT_MAP="ISO8859-1"
CONSOLEFONT="ruscii_8x8"
HARDWARECLOCK="localtime"
TIMEZONE="Europe/Stockholm"
USECOLOR="yes"

I use following shell script to send email. But the subject of email always shows "This" instead of "This is L_1.R is finished". You may refer http://www.linuxquestions.org/questions/linux-newbie-8/how-to-define-variable-in-%60ssh%60-4175540566/
Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_2" "L_3" "L_4")
subject="The job is finished"
ssh -f c15-0330-01.ad.mtu.edu 'echo' "the job ${program[0]} is finished" '|' 'mutt "zwang10@mtu.edu" -s' "This is "${program[0]}".R is finished";

Even though they are on the same Volume Group?

I'm still having a hard time understanding this.

Let's say for example, that I have the following:

Code:

# df -ha

VolGroup00/LogVol2     /tmp

VolGroup00/LogVol5     /opt

VolGroup00/LogVol3     /var

I have three different Logical Volumes where /tmp, /opt and /var live. Are these separate like a partition that one would place on a physical disk?

Keep in mind that they all are on the same Volume Group as well?

Hi,
I have patched GPSR to ns-2.35 using keliu' code. It works fine with given tcl file. I need to move nodes according to mine own mobility scenario and compare them to AODV protocol.
I have two problems
1. I don't understand what this command in gpsr.tcl file means Code:

proc gpsr-create-mobile-node { id args } {
         .........................	
if [info exists opt(energy)] {
	$node addenergymodel [new $opt(energy) $node 10 0.5 0.2]}
         .............

What are these figures (0.5, 0.2), are these energy consumed in reception and transmission or some thing else.

Secondly I want move mobile node created using proc defined in gpsr.tcl file according to my own mobility plan e.g. Code:

 $ns_ at 0.000000000000 "$node_(0) setdest 144.816950690450 20.073824649527 0.324133202939"
$ns_ at 0.000000000000 "$node_(1) setdest 93.957720171475 192.140808646867 1.452613500562"
$ns_ at 12.158688172971 "$node_(23) setdest 113.137798368154 39.443538618334 0.902003496971"
$ns_ at 14.805074599534 "$node_(2) setdest 152.227654369397 20.766089279052 1.742469780423"

But when I run simulation it gives error like this:[QUOTE]Load complete...

Urgent help is needed please

I am trying to put back together a big atr file from some smaller tar files that I created several years ago. The issue is that in order to tar this large file, I must put each file back using the command

tar -xMf cd-1.tar
Prepare volume #2 for 'cd-1.tar' and hit return:n cd-2.tar
Prepare volume #3 for 'cd-2.tar' and hit return:n cd-3.tar
and so forth.

I have fourteen files cd-1.tar through cd-15.tar. The cd-9.tar files is missing and I assume that it is gone. Now when I type the commands in I get the following:

Code:

-linux tarfile]$ tar -xMf cd-1.tar
Prepare volume #2 for `cd-1.tar' and hit return: n cd-2.tar
Prepare volume #3 for `cd-2.tar' and hit return: n cd-3.tar
Prepare volume #4 for `cd-3.tar' and hit return: n cd-4.tar
Prepare volume #5 for `cd-4.tar' and hit return: n cd-5.tar
Prepare volume #6 for `cd-5.tar' and hit return: n cd-6.tar
Prepare volume #7 for `cd-6.tar' and hit return: n cd-7.tar
Prepare volume #8 for `cd-7.tar' and hit return: n cd-8.tar
Prepare volume #9 for `cd-8.tar' and hit return: n cd-10.tar
tar: This volume is out of sequence (10755138772 - 4889670868 != 6598651392)
Prepare volume #9 for `cd-10.tar' and hit return: n cd-10.tar
tar: This volume is out of sequence (10755138772 - 4889670868 != 6598651392)
Prepare volume #9 for `cd-10.tar' and hit return: 
tar: This volume is out of sequence (10755138772 - 4889670868 != 6598651392)

As you can see I do not have cd-9.tar. That stops the untarring cold. However, I have cd-10.tar,cd-11.tar,cd-12.tar,cd-13.tar,cd-14.tar,cd-15.tar. Now I may have these files, but they cannot be put back in the main file because cd-9.tar is missing and everything must be put in sequentially.

Is there a way to complete this sequence of steps and add all fourteen files to the files bigbackup leaving out cd-9.tar? That means that the bigbackup file will be incomplete, but that is better than no file or having bigbackup missing six files on the back end.

Any help appreciated.

Thanks in advance.

I have been using an old computer to download my torrents and this has been my usual routine:

1. Press the power button.
2. Connect to the computer through Putty
3. Log in
4. Gain su privileges

Startup Commands:
Code:

/etc/init.d/transmission-daemon stop
apt-get update
mount -t ext4 /dev/vgTransmission/lvTransmission /mnt/transmissionVault
/etc/init.d/transmission-daemon start

Shutdown Commands:
Code:

/etc/init.d/transmission-daemon stop
umount /dev/vgTransmission/lvTransmission
shutdown -h now

I was wondering if there is a way to configure a computer to automatically mount a logical volume “before” the transmission-daemon starts at boot up (note my first Startup Command).

I think the instructions here are related to what I want to do, but I want to get some advice before I attempt to do anything dangerous:
http://tille.garrels.be/training/tld...#sect_04_02_04


My perfect scenario would be:

Startup Routine:
1. Send WakeOnLan magic packet to computer to turn it on.
2. Computer boots up, mounts the transmissionVault logical volume
3. Wait 10 seconds to ensure that the logical volume has finished mounting
4. Start transmission-daemon

Shutdown Routine:
Send WakeOnLan magic packet to turn off computer, i.e.: Execute “shutdown -h now”
The shutdown command should include:
1. Stop transmission-daemon
2. Wait 10 seconds to ensure that transmission-daemon has finished shutting down
3. Umount transmissionVault logical volume




Recently the Ethernet port of my transmission box has stopped working, so I went ahead and swapped the motherboard with another old motherboard, added a few hard drives, installed a fresh copy of Debian, and re-created the LVM logical volume for transmissionVault. I pretty much have a fairly stock system running at the moment.

Running a headless 3.2.0-4-amd64

Code:

PREFIX=192.168.1
OCTET=1
while [ $OCTET -lt "255" ]; do
    echo -en "Pinging ${PREFIX}.${OCTET}..."
    ping -c1 -w1 ${PREFIX}.${OCTET} > /dev/null 2>&1
    if [ "$?" -eq "0" ]; then
       echo "OK"
    else
       echo "Failed"
    fi
    let OCTET=$OCTET+1
done

My question is, in the penultimate line, why is it OCTET, and not $OCTET, with a dollar before it, meaning, the variable?

What if it were written:
Code:

let $OCTET=$OCTET+1

Like in C++ (I think) or Python or whatever?
