Implementing a new system call in Kernel version 2.6.32

A system call is used by application or user programs to request service from the operating systems. Since the user programs does not have direct access to the kernel whereas the OS has the direct access. OS can access the hardware through system calls only. The following files has to be modified for implementing a system call /usr/src/linux-2.6.32.5/arch/x86/kernel/syscall_table_32.S /usr/src/linux-2.6.32.5/arch/x86/include/asm/unistd_32.h /usr/src/linux-2.6.32.5/include/linux/syscalls.h /usr/src/linux-2.6.32.5/Makefile New set of files to be created Create a new directory newcall/ inside the path “ /usr/src/linux-2.6.32.5/ ” Create new files Makefile, newcall.c and put them in the /usr/src/linux-2.6.32.5/newcall/ folder Create new user files (in any folder of Linux) to test the system call testnewcall.c, testnewcall.h (created in /home/pradeepkumar ) syscall_table_32.S Find the file /usr/src/linux-2.6.32.5/arch/x86/kernel/syscall_tab

How to Access MOODLE in Intranet and Internet

When Moodle is accessed either in Intranet or internet, there will not be any issue. But occasions when the MOODLE Site has to be accessed both in the intranet and in the Internet, here is a simple trick Server Used: IBM Blade Servers Operating system: Windows Server 2008 Moodle Version: 2.4 WAMP Server is used. Number of Users: 3000 (Students) + 200 (Faculty) Open the config.php from ~/moodle/config.php include these lines $CFG->wwwroot = 'http://'.$server_id.'/vitcc'; $CFG->dataroot  = 'C:\\wamp\\moodledata'; before the following line $CFG->directorypermissions = 07xx; Restart the WAMP Server and you can Check MOODLE Site both in Internet and Intranet. The above Image tells the intranet Link and the internet link can be opened outside the campus network
