Its not reall a Live CD anymore. Its more like a Live DVD. Anyhow, I don't plan to reduce any educational packages. I'l see what other things I can get rid off. Regards, Sameep

Wow!!! I really didn't expect someone to create a customized CD for me that fast. Thank you very much. I will also have to learn this magic :) Any pointers? Hey no problem. I'm going to make another one tonight. I'm going to aim for around 300 Mb. I'll let you know how it goes. Any ideas on how you would like me to share it ? > I will contact you off list. Thanks once again. Regards Aseem -- http://mm.glug-bom.org/mailman/listinfo/linuxers

Need Live CD Focused on "Education"
by Aseem Rane 28 Jul '08

28 Jul '08

Hi All, Around 2-3 Years back I handed over a "EduMorphix" CD to a kid. Recently I was surprised to find her using it even till date. I noticed that most of the applications on it are quite old compared with the versions that my daughter plays with. I want to give her a Live-CD with updated software since I cannot install anything on her dad's machine. Unfortunately EduMorphix does not exists anymore. EduMorphix was just perfect, I dont know why they decided to dis-continue it. Freeduc (http://www.ofset.org/freeduc-cd) is not updated in a long time either There is no Live CD for edubuntu. I am looking for any distibution including at least "TuxPaint", "TuxMath" and "gCompris". Can someone suggest a live CD focused on Education? Regards Aseem

Please note > i am using Unix as OS and using vi editor. There are few possible solutions: 1. Keep the password in plain text in a separate file in your home directory and read it from the script. The permission of file/directory containing your password should be such that it is not readable by anyone but you. This solution doesn't save you from trouble if someone accesses your file with your own login name. 2. Do the same as above, but encrypt the password with some key and supply that key to the script to decrypt the password. This will force you to supply the key every time you try to run your script. This will prevent anyone from executing the script unless the key is known to that person. But there is a better ways to do it. See below. 3. Instead of cooking up an encryption scheme yourself, use ssh for all remote work. Remember to disable password based logins on remote systems. Choose key based login instead. You need to create your own private-public key pair for this purpose. There are lots of documents on the Net on how to do it. Some of them are: http://sial.org/howto/openssh/ https://wiki.systemsx.ch/display/ITDOC/OpenSSH+key+creation+HOWTO http://www.sshkeychain.org/mirrors/SSH-with-Keys-HOWTO/ http://www.openssh.com/manual.html Never attempt to implement ssh without reading all relevant documents thoroughly as misconfiguration of it can cause serious security breaches. Usually the standard configuration files which come with binary packages in various Linux distributions (Ubuntu, Fedora, OpenSuSE etc.) are secure enough to be used on production systems. But still it makes sense to read and understand them before implementation. Remember to encrypt your ssh private key. Never leave it on the disk in raw form unless you have some compelling reasons to do so. Sometimes using passphrase based encryption is not feasible at all, like to auto-execute some commands on remote system when human operator is not present in front of the terminal to supply it. In such cases, the private key is kept on the disk in its raw form. I am assuming that your are present in front of the terminal from where your program is fired. This will allow you to supply the passphase on demand. If your program is fired multiple times in a session or connects to multiple systems in a session then these password prompts might become annoying. In such cases, consider using the utility ssh-add. It takes your passphrase while starting up and keeps it in the memory for on demand supply. Thus you can supply the passphrase once and then run your program without supplying it again. But remember to run "ssh-add -D" when all your ssh related work is over. > Can any one please advice or guide me how to achieve this > kind of encryption. If you mean a custom encryption scheme here, I would say that cooking up such a scheme is always a bad idea. It requires a lot of mathematical skills to develop a good encryption scheme. So it is better to leave this job to the experts (unless you are a good mathematician yourself) and enjoy the fruits of open and standards compliant encryption schemes already developed by great masters. cheers Raghu

Software Patents Issue" Meeting on 7th August
by Venkatesh Hariharan 28 Jul '08

28 Jul '08

If there are articulate FOSS developers in the Mumbai LUG, I would request them to be present at the 7th August 2008 meeting and explain to the group why software patents are against the interest of the developer community. Venky ===== http://osindia.blogspot.com/2008/07/patent-office-meeting-in-mumbai-on-7th.… Sunday, July 27, 2008 Patent Office Meeting in Mumbai on 7th August: Please attend if you can<http://osindia.blogspot.com/2008/07/patent-office-meeting-in-mumbai-on-7th.…> This is a call for FOSS developers in Mumbai who are interested in the software patents issue. The Patent office has called for a stakeholders meeting<http://ipindia.nic.in/whats_new/StakeholderMeeting_24July2008.pdf>on the Draft Patent Manual <http://ipindia.nic.in/ipr/patent/DraftPatent_Manual_2008.pdf>. On behalf of Red Hat, I have submitted our comments on the manual<http://ipindia.nic.in/ipr/patent/Patent_Manual_Feedback/REDHAT_INDIA_PVT._L…> . In 2005, I was involved in the Patent Amendment Act 2005 and on behalf of Red Hat, we had made representations to policy makers on why software patents are bad for the Indian software industry. At that time, Lawrence Liang and Prashanth Iyengar of the Alternative Law Forum had done a fantastic job of putting together a position paper on this issue virtually overnight. Happily, our lobbying was successful and software was kept out of the Amendment. What makes me hopping mad is that the Draft Manual seeks to bring in through the backdoor, something that was explicitly rejected by the Indian parliament. To say the very least, this is a very dubious practice. Interestingly, Infosys and TCS are in favor of software patents. Those who followed the OOXML fight on this blog would know that both these organizations had voted in favor of Microsoft's OOXML proposal. If there are articulate FOSS developers in the Mumbai LUG, I would request them to be present at the 7th August 2008 meeting and explain to the group why software patents are against the interest of the developer community.
