Sometimes your Windows 7 installation becomes corrupt, and you need a way to recover, you can use the original Windows 7 installation cd. However, it is always good practice to make your own, specially if you are running a 64 bit version of Windows 7, and the installation cd will not work. Here are the steps to create a System Repair Disk.
1- First, click start–>Control Panel–>System and Security
2-Second, Click on Backup and Restore Read the rest of this entry »
Since the release of Ghost Solution Suite 2.5.x, Symantec decided to add support for Linux partition in their ghost clients; however, as far as I know ext4 is not yet supported. As part of the IT job, IT Pros have to rely on some sort of imaging software, and if I can make images of every OS out there with a single application, even better. You can read more info on the support of ghost and Linux partition here. For this tutorial I will go over the steps on how to create a ghost boot disk with Linux support. By the way now the default for a ghost boot disk uses Windows Preinstalled Environment (WinPE).
1- First open the Ghost Boot Wizard, and select default and click next
If you’re like me that test pretty much any os and apps in some sort of virtual environment. In my case I use VMware Workstation, so when I decided to test Backtrack 4 final, I needed to install the vmware Tools, and here I go over the commands needed to install the vmware tools.
1- First go to VM->Install Vmware Tools (the figure shows as Reinstall VMware Tools because I had previously installed it) but yours should say “Install”
If you happen to move to vista or windows 7 like me, you have realized that hyper-terminal is no longer available. Although you could still make hyper-terminal work in windows 7 by copying the executable along with a dll file, I find that is much easier and convenient to use Putty. Putty offers many ways to connect to remote device like SSH, Telnet, and Serial. Here I describe how simple it is to connect to a device like a CISCO Router or switch using Putty.
1- First start by downloading putty from here
2- Second find on the device manager what is your serial connection: COM1 or 2 etc.
I decided to make a guide about TCP/IP configuration in Linux, and you may ask: well, what Linux distribution in specific? I know!, there are hundreds of Linux distribution, but for this guide, I’m only going to cover the two most used Linux distribution: Ubuntu and Fedora. Ubuntu is a Debian derivative, so the Ubuntu portion of TCP/IP configuration applies to any distro based on Debian. And the same goes for Fedora, which is based on RedHat Linux.
First, you want to find out what interfaces you have, and what ip address, “if any,” was assigned to your computer. For this use the “ifconfig” command:
ifconfig #will list all enabled interfaces
if you are looking for a specific interface:
ifconfig eth0 #will only display the configuration for eth0 interface
If you get no interfaces other than the loopback address, it is time to do some troubleshooting and find out whether your network card was detected by Linux or not.
sudo lspci | grep -i ethernet #displaying all your ethernet cards
if you’re troubleshooting a wireless card just change “ethernet” for “wireless.”
other useful command when troubleshooting network card and drivers is “lsmod” Read the rest of this entry »
To see which processes are currently on a system, most people use the “ps” and “top” commands. The “ps” command gives you a snapshot (in a single list) of processes running at the moment. The “top” command offers a screen oriented, constantly updated listing of running commands, sorted as you choose ( by CPU, memory, UID, etc).
ps #List processes of current user at current shell
root@ubuntu-box:~# ps PID TTY TIME CMD 2988 pts/0 00:00:00 su 2996 pts/0 00:00:00 bash 3047 pts/0 00:00:00 ps
ps -u jorge #Show all jorge’s running processes
root@ubuntu-box:~# ps -u jorge PID TTY TIME CMD 2662 ? 00:00:00 x-session-manag 2725 ? 00:00:00 VBoxClient 2730 ? 00:00:00 VBoxClient 2737 ? 00:00:00 VBoxClient 2748 ? 00:00:00 ssh-agent
ps -u jorge u #Show all running processes with CPU/MEM Read the rest of this entry »
Running out of disk space can be annoying on your desktop system and potentially a disaster on your servers. To determine how much disk space is available and how much is currently in use, you can use the “df” command. To check how much space particular files and directories are consuming, use the “du” command.
The “df” command provides the “-h” options which output in a human-readable, usually in MB or GB.
This command display space on file systems in human-readable form
[root@Fedora11-vbox ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_fedora11vbox-lv_root
6.7G 3.6G 2.9G 56% /
/dev/sda1 194M 21M 163M 12% /boot
tmpfs 250M 292K 250M 1% /dev/shmIf you have remote share mounted, these will show up too. So to limit the output to local systems only:
df -hl
To check for disk space usage for particular files or directories in a file system:
[root@Fedora11-vbox ~]# du -h /home/ 4.0K /home/smbuser/.mozilla/plugins 4.0K /home/smbuser/.mozilla/extensions 12K /home/smbuser/.mozilla 4.0K /home/smbuser/.gnome2
If you have root priviliges, you can use the “-s” option to get a summary of disk usage; otherwise, you will get “permission denied” when trying to access directories that you don’t have access to. Read the rest of this entry »
