jNetMap is a graphical network monitoring and documentation tool. It will ping all registered devices every x minutes, updating the status according to the result of the ping.

jNetMap helps you to keep an eye on you network. You can draw a graphical representation of your network, and jNetMap will periodically check if the devices are still up or a service is still running. You can also set up E-mail notifications or let jNetMap execute a script when a device goes down or comes up again. Additionally, you may attach notes to a device, initiate an RDP/VNC/SSH connection to a device and much more.

Note: jNetMap is not a network discovery/auditing tool, there are better tools out there for that. And for an enterprise grade monitoring solution, you should check out Nagios instead. The idea here is to have a mission control center-style display for networks.

  • Shadow opacity.
  • Shadow delta X, Y, width and height.

  • frame opacity.
  • resize window opacity.
  • popup opacity.

Also it provides options to swich on / off composite, dock shadow, frame shadow, pop-up shadow and Restart VM to apply changes.

Below is what the developer said in GTK-Apps, “These settings are available via the xconf settings editor but that is one of the most awkward GUI’s I have ever used as you have to select the xfwm4 channel, expand the tree, scroll to the option you want, select it, click edit, change the setting and click save, then the tree gets collapsed and you have to start again! So this nice simple GUI to control the composite manager, the settings are self explanatory.”

This simple and brief tutorial will show you how to backup live CD or DVD to iso image on Ubuntu Linux using dd command.

dd is a command on Unix and Unix-like operating systems whose primary purpose is to convert and copy a file. On Unix, device drivers for hardware (such as hard disks) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read from (and in some cases write to) these files. As a result, dd can be used for tasks such as backing up the boot sector of a hard drive, and obtaining fixed amount of random data.

To make iso image out of CD or DVD:

Insert your live CD or DVD into computer, then you can check the device name by running below command:

df -lh

You’ll get a similar output. The last line tells the device name /dev/sr0 and mount point /media/handbook/CD-Rom

Filesystem Size Used Avail Use% Mounted on
/dev/sda6 92G 47G 41G 54% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 870M 4.0K 870M 1% /dev
tmpfs 176M 980K 175M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 878M 3.5M 874M 1% /run/shm
none 100M 56K 100M 1% /run/user
/dev/sr0 807M 807M 0 100% /media/handbook/CD-Rom

Now, use below command to create iso from it:

dd if=/dev/sr0 of=~/backup.iso bs=1000000 count=512 &&sync

Here if reads from file /dev/sr0, of write to file backup.iso, ~/ means user home directory. The value of ‘bs’ means read and write up to 1000000 bytes at a time.

For more, run:

man dd
