I think this above case covers 65% of nett usage and context. Case 2: WHEN the recipient must read or view the file with M$Office THEN use OpenOffice to create/edit, then save as the M$Office format (doc, xls, ppt) and release that file. I have not experienced any issues in traffic FROM OpenOffice TO M$Office. I think this above case covers 25% of nett usage and context. Case 3: WHEN sender and recipient must collaborate on a document, i.e both contribute to editing/marking/revising the file via electronic file exchanges THEN it is most practial or efficient to work with the same application/tool on both sides, and this case is NOT specific to OpenOffice; it is equally applicable to almost all computer applications, especially those that do not support open standards/specifications of data storage. I think this above case covers 8% of nett usage and context. Case 4: WHEN something other than above THEN I need to know more, to share my prescription for that case ;-) I shall presume this above case covers the last 2% of nett usage & context. LASTLY, if you take two similar segment cars for example, how much of compatiblity is expected ? Do we expect say an Indica and a Santro to be the same, with all parts to be interchangeable ? This example many can easily comprehend. However, when it comes to M$Office and OpenOffice, many of us tend to struggle with explaining or realising compatiblity. I guess we have to EITHER pay-up (and remain a loser) OR move-up to open standards (with longer term gains). > The other issue that people in India generally face is of bandwidth. > Ubuntu installs well.

Figure out how to re-configure the linux-desktop so that it does NOT get upates automatically via the internet - thus manage their internet usage better. Instead use CD's to effect updates, as other posters have suggested already. With the virus-risks on Linux-based desktops being relatively lower, not having the latest releases is often a non-issue, in terms of real-life utility of the environment/computer, for most average desktop users. If you want to be up-with-the-Jones with the latest release, then paying some price is inevitable (internet bandwidth costs). Thanks Vydya

pls test my LAMP installation
by Agnello George 02 Aug '07

02 Aug '07

Please test my LAMP instalation aqnd let me know if you find any errors .... this wud be really gr8 help 1. Installing Apache 2.2.3 a) Download the Apache 2.2.3 source files from http://httpd.apache.org b) Extract the source from the gunzipped file using tar or gunzip c) change the working directory to the directory containing the extracted source files d) Run the following command for basic apache installation ./configure --prefix=/usr/local --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql --enable-shared=max --enable-module=rewrite --enable-module=so --enable-shared=ssl --enable-ssl --with-ssl=/RPM/openssl-0.9.8d make make install 2. Installing PHP 5.2.0 a) Download the PHP 5.2.0 source files from http://www.php.net b) Extract the source from the gunzipped file using tar or gunzip c) change the working directory to the directory containing the extracted source files d) Run the following command for PHP installation ./configure --prefix=/usr/local/php5 --with-apxs2=/usr/local/apache/bin/apxs --with-libxml-dir=/usr/local/lib --with-zlib --with-zlib-dir=/usr/local/lib --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-gd --enable-soap --enable-sockets --with-jpeg-dir=/usr --enable-exif e)Build the PHP configuration using the following command make f) Install PHP make install 3. Installing MySQL 5.x a) Download the MysQL source files from http://www.mysql.com b) Extract the source from the gunzipped file using tar or gunzip c) Create the mysql user and group using the following commands groupadd mysql useradd -g mysql -c "MySQL Server" mysql d) Create a symbolic link to the MySQL source directory in a directory of your choice. (I use /usr/local/). Here is an example of the same ln -s /software/mysql-max-4.1.22-pc-linux-gnu-i686 /usr/local/mysql e) Change the working directory to the symbolic link that you have created in the server. f) Execute the following command ./scripts/mysql_install_db The above command will install the mysql and the test database g) Change the ownership of /usr/local/mysql using the following command chown -R root:mysql /usr/local/mysql Where root is the user and mysql is the group h) Change the ownership of /usr/local/mysql/data using the following command chown -R mysql:mysql /usr/local/mysql/data i) Copy the default configuration file for the expected size of the database (small, medium, large, huge) cp support-files/my-medium.cnf /etc/my.cnf chown root:sys /etc/my.cnf chmod 644 /etc/my.cnf j) Now we have to tell the system where to find some of the dynamic libraries that MySQL will need to run. We use dynamic libraries instead of static to keep the memory usage of the MySQL program itself to a minimum. echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf ldconfig k) Now create a startup script, which enables MySQL auto-start each time your server is restarted. cp ./support-files/mysql.server /etc/rc.d/init.d/mysql chmod +x /etc/rc.d/init.d/mysql /sbin/chkconfig --level 3 mysql on l) Then set up symlinks for all the MySQL binaries, so they can be run from anyplace without having to include/specify long paths, , etc cd cd /usr/local/mysql/bin for file in *; do ln -s /usr/local/mysql/bin/$file /usr/bin/$file; done m) First, we will assume that only applications on the same server will be allowed to access the database (i.e., not a program running on a physically separate server). So we'll tell MySQL not to even listen on port 3306 for TCP connections l ike it does by default. Edit /etc/my.cnf and uncomment the skip-networking n) Start MySQL -- Warm Regards Agnello .

[OT] Breathing life into old speaker sets.
by Rony 01 Aug '07

01 Aug '07

Hello All, I had an old Lamington Road power amp with equilizer that went kaput twice and finally its speaker set that I had made from discarded huge wooden speaker boxes and 8" Phillips Hi-Q speakers were lying idle, gathering dust. I was using a 2.1 channel computer speaker set for my TV set top box. As an experiment I removed the small satellite speakers and replaced them with my old speaker boxes and now I am enjoying theatre like sound for programs and movies. Just take care not to go full volume as the impedence and power ratings differ greatly. -- Regards, Rony. Knock Knock Who's There? Linux Who Linux? GNU/Linux

PHP has a module to handle SSH2 related activities. Following link explains about sending data using scp; along with a small example. On the same page, hyperlinks with details of other ssh2 functions are provided too. http://in2.php.net/manual/en/function.ssh2-scp-send.php Raghu

[OT] while(condition) vs while(true) break
by Siddhesh Poyarekar 30 Jul '07

Hi All, This is probably a very basic question but here goes anyways -- which would be faster in C/C++ (or would it make no difference at all?): while(condition) { ... } OR while(true) { ... if(condition) break; ... } Thanks, Siddhesh -- Siddhesh Poyarekar This document validates as Plain Text

> you can do ssh key exchange between the hosts, for a particular user login. > beware it will never ask for password, when you do ssh to that box, or > create a shell to exit if done ssh It does ssh key exchange without a password provided no passphrase exists for the key. In case a passphrase exists you have to put it in. Also since keys are dependent upon user account or user permission from which the command is being executed so the appropriate ssh key of that person stored in the ..ssh or appropriate directory is used. In case you do have a passphrase you can use an ssh agent to load the private and once you key in the private key the agent takes care of the connection and for further it will not ask for the passphrase. I think you can also tell the ssh agent not to take input from a file and not standard input. Look for it other ssh agent will solve the purpose. See ssh-add it will do the trick for you. By default it loads the private key from the identity file. Regards, Vivek -- Put a rogue in the limelight and he will act like an honest man. -- Napoleon Bonaparte, "Maxims"

SCP command line within PHP
by Abhishek Daga 30 Jul '07

30 Jul '07

I am currenty SCping using the command line, where i am asked for the password in order to run the command. Now I wish to run the SCP command from within a php script. I'd rather enter the password each time in a form rather than store it within the script itself. How can I handle the password request? i.e., pass the password to the remote system when it asks for it. thanks abhishek ____________________________________________________________________________________ Choose the right car based on your needs.
