Using LiveCD for net connection


I've read that you can connect to the internet after booting from a Linux LiveCD. How does this work?

For example, if you use dialup, and modem+connection sw are configured, you just connect as usual? I'm conceptually fuzzy on this--since the sw for dialup lives on the hard drive, you can access the hard drive as usual?

And if you have doc or text files on a USB flash drive, you can access the flash drive and open+edit the docs using a text editor included on the LiveCD?

Yes(after you setup the modem+connection sw on the live cd).

you'll have to install the sw on the liveCD before dialling up

yes, but you cannot run applications installed on the OS in the hard drive, you can access all data on it after mounting it.

yes

Remember, any changes made in the LiveCD will disappear post reboot (unless you make it persist to an external device like say a USB thumb drive)

Thanks for info and for fixunix.com link to procedure. I had a gap in my understanding of the interaction between LiveCD and hard drive. So from LiveCD you can read hard drive (after mount) but not run pgms; and changes aren't saved to hard drive, but you can save to flash drive.

not directly answering your question but i would recommend a live-usb because it seems that you need to store data on it.

you should be able to run programs from a mounted source; it's just data...

Almost every disto offers a live cd. Depending on ram you may or may not be able to download stuff live. In most cases you can create a spot for session data but all distro's are easy that way. The live cd is more a one time thing now. One used to be able to save persistent data to a floppy or usb or hard drive. Now we more often think of using a usb flash drive install with persistence to safe both the OS and persistent data.

Thanks, i didn't know that was possible. As an example, suppose the hard disk has a linux distribution in it, would the OP be able to run say, OpenOffice off the hard disk while using the LiveCD???

^ probably not without a lot of tweaking (i dont know; never tried it).
i would be worried about where the live system would be looking for certain paths (header files, shared libraries, object files, ...) which would be different from the installed system.
i was talking about self-contained hello-world type programs.

i'll try it next time i boot up my live-usb.
