I have no clue about the manual module installation, I would be really thankful if you provide me a link which could explain me the entire process. Thanks

your best option for fedora 15 is well install 24
BUT

seeing as you are stuck with a very old version that is missing YEARS of security updates

have a look at the Fedora " END OF LIFE" forum
http://www.forums.fedoraforum.org/forumdisplay.php?f=75

i see you have a post there about backing up 15

If it worked originally then the problem should have been hardware related, not software.

jpollard I think its software related as everything is same (hardware) earlier there was a input problem which I have already explained (one key press would result in numerous entries) at that time the printer was working fine, But when they resolved the key press issue this printer issue came up... My friend I am not an expert when it comes to Linux but I am trying to learn .. when I compare the old installation to the new.. In the old one I could see the ppdev , parport modules etc but this new one doesnot have these. moreover there is nothing in /boot (absolutely empty)... It would be really helpful if I could talk to you on skype or gmail so I can explain you about this issue better.. I badly need help in this please write to me...

The /boot may be empty because it is not mounted, it does not need to be mounted for normal operation. If your new installation is simply stripped old installation feel free to get parport module and copy it over, there is no reason for it not to work.

The directory listing for /lib/modules was incomplete - it showed the 2.6.38.6 kernel had modules present (the directory itself), but not the contents of the directory (which is a fairly long list with additional directories within).

If the system is fairly generic, /boot is in a partition of its own and happens to not be mounted. This is reasonable for a kiosk operation as it isolates the partition from accidental (or not so accidental) overwrite. But to see the kernel configuration it has to be mounted.

Thanks for your reply Emerson.Actually as I mentioned earlier, I am not an expert but trying to learn .. are you saying that simply copying the modules and pasting them to the new installation will work ? and please can you state what all modules are necessary for connecting a parallel port printer..

One key press resulting in multiple entries is most frequently a keyboard problem (dirt gets in causing the key to generate multiple activations; sometimes a cheap return spring isn't strong enough). The few other times it can happen is by setting the repeat time interval too low (by default it is about 1 second). Setting it too low (some high speed typists do this) can cause issues. But still not a driver problem.

I also agree that just coping the modules (to the right destination) should work.

My friend this is from a working machine, the one where the printer is not getting detected has nothing inside /lib/modules .. Can you please suggest me which modules are responsible for detecting a parallel printer and if I copy these from an old machine to the new problematic one will it make the printer work ? or do I have to do anything else ??..

These kiosks are touch screens so the first case of dirt is eliminated, so you are saying that the repeat time interval is too slow... Can you please tell me how to change the repeat time interval ? is there a command that can do the job ?

You will have to look at the disk of the old machine. There SHOULD BE MODULES. The only time there won't be is if ALL the drivers were include inside the kernel. If there are none there either, then the new kernel was misconfigured by leaving the modules out.

This is partly why modules were used. It allowed the kernel to augmented where desired without the bloat of unused drivers. I can understand why they may not exist - the security of the kiosk could have been deemed paramount, thus all drivers are included in the kernel to prevent having a subverted one added.

But that makes it even more necessary to get the configuration file used from someplace and rebuild a kernel for the target machine.

Dirt isn't entirely eliminated - I have had problems with touch screens when they have some conductive dirt/oil on them (they were capacitive, yours might not be).

The time interval is controlled from several places - one is BIOS setting, another is under an accessability setting - just turning off the bounce was sufficient. (https://ask.fedoraproject.org/en/que...eat-key-issue/)

This is not the way the community forums work. We aren't a place to come for free, personalized one-on-one chat/email tech support. While I can't speak for jpollard, I find it HIGHLY doubtful you'll get people to do this. Those persons are called "consultants"...they will give you as much time as you'd like, but you have to PAY THEM. Otherwise, questions and answers here are for the benefit of the entire community, not just you.

While I realize everything you're saying about this being a custom kernel...you also have to realize that, at some point (and it's looking like 'right now' is that point), the hardware will die. Trying to struggle on keeping an ancient version of an OS running is pointless. Spend the time migrating things to a new version of Linux, which will support NEW hardware. Fedora 15 had issues when new...even more now, since you won't have any bug fixes/updates. Get your hardware and software working with the latest versions of things, and sidestep a ton of issues.

A better question is: how do you KNOW that your custom-kernel supported hardware doesn't 'just work' out of the box with a newer version of things? You may be able to just plug it in, and have it work with a new version.
