Re: [ILUG-BOM] Need Live CD Focused on "Education"

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 Hi, You can make your own LiveCD with whichever packages you need. You can remove whatever you don't need. Most distros have an option of making a custom LiveCD. It takes about half an hour. Alternatively you can tell me what packages you need and I'll make a LiveCD for you. :-) Regards, Sameep

> How about posting a mini-howto for the process? Or the pointer(s) for the same? > > With regards, > -- > --Dinesh Shah :-) The custom iso is very easy to make. How much time it takes depends on the kind of customization your looking for. On a Ubuntu / Kubuntu based system , you can use remastersys or reconstructor. http://www.howtoforge.com/ubuntu-linux-mint-livecd-with-remastersys Thats a how-to on remastersys to get you started. The only thing to remember is that remastersys will automatically include all packages installed on your system into the custom distribution. So its best to use it on a new install. That will prevent installation of unrequired software. Here is the link for Reconstructor : http://reconstructor.aperantis.com/ This is a good tool as well. Has some more customizations. The best way is to make a Live Distro from scratch. That way you can keep it quite trim by removing all unnecessary packages. You can also have a different window manager if you want to keep it really small. There are also tools to customize fedora , knoppix, slax , DSL etc. Another tool worth mentioning is Insta Linux http://www.instalinux.com/ Its a online app where u can choose what apps you want. It generates a custom cd for you on the fly which you have 24 hours to download / distribute. The avaiable applications are quite limited though. Regards, Sameep

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

This is from the website Current status * Targeted release: Fedora 10 * Last updated: 2008-07-27 * Percentage of completion: 70% Regards, Sameep P.S. I have added Hindi support in the Custom Distro.

Re: [ILUG-BOM] encryption of password

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
