Call for Papers Talks are the main part of the conference: a series of presentations on Free Software related subjects. This year there will be 20-30 presentations. Presenters will be given a 50 minute slot, which includes up to 10 minutes for questions. The main programme also has 8 tutorial slots. Tutorials are longer and more interactive presentations, with slots lasting for 160 minutes, giving the speaker time to interact with the audience.

Pushing Linux through small vendors
by Dinesh Joshi 04 Aug '07

04 Aug '07

Hi people, A few days ago my computer vendor came to me with some real problems regarding Linux. Hes a small time guy who supplies assembled PCs to individuals and maybe some small companies. Anyway, he owns an office and himself is pissed off with Microsoft's products as he has to format the machines every other day. Another reason pushing him towards Linux is that hes now getting inquiries regarding installing Linux from home users. And Vista cracks are not yet stable and widely available :P After having a small chat with him, I got his requirements. For office use, he requires: 1. Microsoft Office - docs and excel spreadsheets 2. Internet Explorer - surfing / banking etc.. 3. Tally - accounting Now, I'm aware that he has the following alternatives: 1. Open office 2. Firefox 3. Tally ( Linux version ) But the problem with Open Office: 1. With average machines, it performs slow 2. The documents it generates are not 100% compatible with Ms.Office 3. Advanced features are not completely compatible But they need to inter-operate with the rest of the world which means a good compatibility is important. Another problems that one generally faces is that Linux doesn't always work out of the box. When it does, it works wonderfully well but when it comes down to tweaking it to get it to work, its like performing a brain surgery ( for a newbie ). One more issue that I perceive is that distros don't always have good hardware compatibility. Let me explain it in more detail. Ubuntu 6.06 worked well on my friend's machine. No issues. But Ubuntu 7.04 refuses to work on the same machine. Some driver compatibility issues. The other issue that people in India generally face is of bandwidth. Ubuntu installs well. It impresses them. But then it runs up HUGE bills downloading softwares. What are your thoughts on this? How can we work with these people to effective push Linux into homes and offices? This definitely is one of the best ways of boosting Linux user base :) -- Regards, Dinesh A. Joshi

pls test my LAMP installation
by Agnello George 01 Aug '07

01 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 .

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

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"
