NTP Server and Client Configuration in debian 2007-09-19 05:24:18 The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. NTP uses UDP port 123 as its transport layer. It is designed particularly to resist the effects of variable latency (Jitter). Using NTP is a great way to keep your system clock set correctly. It works by contacting a number of servers around the world, asking them for the time and then calculating what the correct local time is from their responses. Install NTP server in Debian #apt-get install ntp ntpdate ntp-server This will install all the required packages for NTP Configuring NTP Server By Default main configuration file located at /etc/ntp.conf Default configuration file looks like below #/etc/ntp.conf, configuration for ntpd driftfile /var/lib/ntp/ntp.drift statsdir /var/log/ntpstats/ statistics loopstats peerstats clockstats filegen loopstats file loopstats type day enable filegen peerstats file peerstats type day enable filegen c ...

Setup CUPS (Common UNIX Printing System) Server and Client in Debian 2007-09-10 09:08:40 The Common UNIX Printing SystemTM, or CUPS, is the software you use to print from applications like the web browser you are using to read this page. It converts the page descriptions produced by your application (put a paragraph here, draw a line there, and so forth) into something your printer can understand and then sends the information to the printer for printing. Now, since every printer manufacturer does things differently, printing can be very complicated. CUPS does its best to hide this from you and your application so that you can concentrate on printing and less on how to print. Generally, the only time you need to know anything about your printer is when you use it for the first time, and even then CUPS can often figure things out on its own. Install CUPS printer server in Debian #apt-get install cupsys cupsys-driver-gutenprint foomatic-db-gutenprint foomatic-filters fontconfig libtiff4 libfreetype6 NOTE:- If your network use DHCP it’s a good idea to set up your serve ...

Mount a remote file system through ssh Using sshfs 2007-09-03 04:34:45 If you want to access a remote file system through ssh you need to install sshfs.sshfs is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there’s nothing to do. On the client side mounting the file system is as easy as logging into the server with ssh. sshfs Features Based on FUSE (the best userspace filesystem framework for linux) Multithreading: more than one request can be on it’s way to the server Allowing large reads (max 64k) Caching directory contents sshfs runs entirely in user space. A user using sshfs does not need to deal with the root account of the remote machine. In the case of NFS, Samba etc., the admin of the remote machine has to grant access to those who will be using the services. Install SSHFS in Debian #apt-get install fuse-utils sshfs Next, let’s make sure the following condition is met. In the local system, type (as root) ...

Howto Boot debian in text mode instead of graphical mode (GUI) 2007-08-29 13:41:21 This is very useful tip for all debian users You can prevent automatic running of the GUI when you boot your debian machine by disabling your login manager be it KDM, GDM or XDM from running at boot time.

Howto display the number of processors in Linux 2007-08-24 01:04:09 If you’ve just bought a new desktop,laptop or server and the box says the box is powered by 2 processors, you can actually verify that. Here’s how to display the number of processor of your linux box. Simply issue the following command as root # cat /proc/cpuinfo | grep processor Everything in linux is files. This command simply retrieves the number of processors that linux detected from /proc/cpuinfo and displays it. Usually, the processor number comes at the first set of line from issuing the command. Here’s what the command returned for me: ~~~~~~~~~~~~~~~~~~~~~~~~ processor : 0 ~~~~~~~~~~~~~~~~~~~~~~~~ which means You have 1 processor with a processor ID number 0. Processor counting starts with 0. So if you have a PC with core duo, you will probably have 2 lines that says 0 and 1.That is 2 processors.

First, determining the path location of the binary is required using the following command # which su returns ~~~~~~~~~~~~~~~ /bin/su ~~~~~~~~~~~~~~~ Remember the current file mode bits and restrictions for su binary # ls -la /bin/su ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -rwxr-xr-x 1 root root 24284 Apr 28 2007 /bin/su ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noticed that su binary is world executable and world readable.
