Network Operating Systems-I

notes apt: apt is a system for installing packages. It can be used for both types of package, and is
primarily used on Debian systems.
To use apt, you need to set up an apt source. On Debian systems, the debian-config program sets
up the sources during the installation process. Apt sources are locations where packages and
package information can be downloaded. Once you have an apt source set up, the command apt-
get install (package name) will install the package for you, and also install anything the package
requires.

If you do not know the package name, the command apt-cache search (keywords) will search
package names, file names and package descriptions for the keywords; and present a list of
matching packages.
$ apt-cache search cervisia
cervisia - KDE based CVS frontend
The command apt-get update will automatically update the source and package lists, and should
be used if you want the latest version of a package.
dpkg: The Debian package manager is another way to install .deb packages. dselect is a graphic
front end to dpkg, and can be called by running the command dselect from the command line.
dpkg can be run directly from the command line, if desired.
alien: alien will convert one sort of package to the other. It works on rpm (Red Hat), deb (Debian),
slp (Stampede), pkg (Solaris) and tgz (archived and compressed) files.
The alien manual explicitly states not to use it for system-critical programs, only for
applications.

Caselet Hitch while installing software

y system has the following configuration: Pentium III processor, 448 MHz, 40GB
Hard disk, 128 MB RAM with Windows XP and Linux as the operating systems.
MRecently I tried to install software named `Acrobat Reader 5.0.’ It appeared to get
installed successfully. But when I tried to open it, it displayed the following error message:
AcroRd32.exe-Bad Image... The application or DLL C:\windows\System32\oledlg.dll is
not a valid image. Please check this against your installation diskette.”
what is causing this problem? please suggest a solution.
Radeep
Oledlg.dll is a windows system file that may possibly have got corrupted in your system.
You can replace this file from the Windows XP installation CD or download it from the
following URL: http://www.dll-files.com/dllindex/dll-files.shtml?oledlg. But before
you do so, please copy the original file (oledlg.dll) to somewhere else. To replace from
Windows XP installation CD, please follow these steps: Click Start - Run - type cmd. This
will bring up the command prompt. Type expand CD-ROM Drive Letter:\i386\oledlg.dl_
c:\windows\system32\oledlg.dll. (For example, if your CD-ROM drive letter is E:, then
type “expand e:\i386\oledlg.dl_ c:\windows\system32\oledlg.dll”). Now check whether
your adobe application works.
If you still face a problem, the next option is to run “sfc /scannow” from command prompt
but you need the Windows XP installation CD.
This problem may be due to the W32/Lovgate-P virus. Please update your anti-virus
definition files and then perform a full scan of your system. For more information.
