How can one have direct access to key strikes. Normally the key strikes that collected by the concerned programme and access to the same is not available to any other user programs. I am trying to write a program to simultaneously catch the key strikes. Obviously for this would require a low-level access to the keyboard. How can one do it ?

I have a single board computer previously running DOS. I recently made Linux running on it. Now that the system is running Linux, I have to translate the code that was supported by DOS. The code has segments that allow direct access of memory mapped registers through the macro _MK_FP and do read/write. I have read that where DOS allows this kind of direct memory access, Linux does not. Is there a way to do this in Linux?

Does a mailserver have to have direct access to WAN or can it be a LAN device with just one NIC ?
We have two WAN access points.
One is an adsl router joined to the switch and all seems fine for internet browsing.
The other is a wireless system with a linksys router joining by way of PPPoE and this appears to connect fine.
This PPPoE is direct to our ISP and where we need to downlod our mail to our pending mailserver.
When the linksys router is also joined to the switch all devices can use either the adsl or linksys to roam the net. 192.168.1.1 linksys & 192.168.1.10 is adsl.
When I join the linksys direct to the mailserver I will then need two NIC's. One for the Linksys and one for the LAN.
This is where the fun has started.
So.... Can I just have one NIC (connected to the switch) on the mailserver?
I've got an Hitachi Deskstar 164GB IDE drive which I've somehow managed to upset while attempting to swap distros. I'm guessing its lost the MBR as I can't get a PC to see it except in the BIOS. The BIOS tells me that the primary master has 164GB, Cylinders 65535, Head 16, Precomp 0, Landing zone 65534 and Sector 255. (my understanding of that info is very limited). The PC won't boot direct from the hdd and a live Knoppix disc can't see it. Trying fdisk -l produces no list. (Naturally, I can't install another distro on it either).
View 10 Replies View RelatedI am using a Dell Inspiron 14R laptop that came with Windows 7 Home Basic. The partitions of my hard disk before installing Fedora 15 were:
Dell (OEM Partition)
OS (C: ) (Primary Partition)
RECOVERY (Primary Partition)
New Volume (E: ) (Logical Drive)
I tried shrinking my C: drive (which has Windows) but couldn't do so hence performed the procedure on E: instead. I did this to create a 15GB unformatted space to install Fedora in. While installing Fedora, I chose the option "Use Free space" under Disk Partitioning Setup but the OS got installed in E: drive. Currently, I am able to use both Windows and Fedora under dual-boot but the problem I am facing is that when working with Windows, I am unable to see drive E: in Computer.
Windows Disk Manager is able to detect the partition and is showing it to be healthy (1st screenshot). Its name now is New Volume and neither am I able to change its path or letter (Error: incorrect parameters) nor am I able to check it using "chkdsk" (Error: cannot open volume for direct access/ GUI doesn't work as well) (2nd screenshot). On the other hand, I am able to access both the partitions in Fedora.
Another point to mention is that after finishing the installation of Fedora, when I started Windows, the Disk Manager as well as Dell DataSafe showed that the Windows Recovery drive had been formatted (maybe inappropriate terminology!) and was no longer retrievable. To rectify this problem, I restored my Windows to before Fedora was installed and I seem to have got the Recovery drive back (1st screenshot) (before doing this, it was nameless and empty).
Normally all I/O goes through the kernel so that it can schedule the operations and prevent processes from stepping on each other. A few special user processes are allowed to slide around the kernel, usually by being given direct access to I/O ports. X servers are the most common example of this isn't it ? give examples for any other processes that are allowed to slide around the kernel ?

PS/ I had nfs shares in my fstab, that I had to remove because as they're not always present, that was blocking for several minutes at boot time... It was not a big issue as those shares were not vital, yet it's unpleasant. The only thing I saw on the changelog was a "nfs-utils" update, maybe it's related ? Maybe the default "timeout" have been changed ?
./ before a command to excute it. Why can't I use direct command? What should I do so I don't have to type ./ before a command. I couldn't find any thread relating to this issue so I post it here. Could someone please explain this and tell me what to do.

View 1 Replies View RelatedSo I have been struggling to make this happen for a bit and cannot figure it out. I want to communicate directly from my non-GUI Debian to my Puppy Linux PC. I have set up my Puppy PC for direct connection as per the instructions in the network wizard. I need to set up my Debian to do the same.
I have done the
auto eth0
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
in /etc/network/interfaces.
I still cannot ping the Debian machine from the Puppy one. Are there any other steps to the direct connection? (I already have the crossover cable in place)
I have also tried this with both PCs connected to a Netgear router. I CAN connect to the debian machine if it is on the router at the IP I assigned it and the Puppy PC is configured to use the router.
Is there a file I can edit or a process I can turn off? I think it's close I am just not sure what I am missing.

View 5 Replies View RelatedI need to re-direct the output within an awk script, but not to already known, fixed filenames. The output file names depend on values of the fields. For example (the actual problem is surely more complicated), if, on a given line, the second field is DATA, the third is 1984, I would like to print some information in a file called output_DATA_1984. This could/would change in the following line of the same input file. Such things are pretty easy in bash, put I cannot do it in awk, as I can only find manual references for redirecting output to fixed filenames between double quotes.

I have recently acquired a HP MSA 2040 san, which they say will work with Red Hat. But I'd much rather use Debian. It's attached to a Gen 9 DL360. I cannot get the OS to see the external drives. I hope it's just me mssing something.
I have told the DL360 to keep the external control in HBA mode, not RAID, not using the hosts RAID intelligence. I think I have set the MSA to offer a couple of disks as a virtual drive. I CAN see the drives in the BIOS boot menu for the DL360, though it doesn't show the virtual voilumes on the MSA, I cannot see the MSA virtual or physical drives once Debian is installed.
I have installed multipath-tools, and the SCSCi utilities.
But no luck seeing the drives.

View 3 Replies View RelatedI am currently running OpenSuse 11.2 still having problems with sound, CD-burning and the like being a total newbie. But I am also a very curious person.
So my questions are: Is it
a) advisable to upgrade to the latest version when there are still problems to solve in the old version and after quite some work the most important functions are up and running
b) is it possible technically speaking to upgrade directly from 11.2 to 11.4 without risking too much.

View 4 Replies View RelatedI'm in the process of building a PC to run Ubuntu 10.04 and I want to use it (eventually) to with Direct TV. I just want to be able to use the PC as the DVR if possible. I'll accept the limitations, but I'm trying to do my homework to make it as easy as possible to use for my family.
I've started out with a BioStar M32 Micro ATX board and an Intel E5300 Dual Core Pentium 2.6Ghz processor, with 2Gigs of Kingston RAM. It runs pretty well, but I've got nothing installed yet (I'm dual booting with Windows Server 2003). Right now it's just in an old E Machines case with a new 500Gig toshiba SATA drive.
Is there a guide to what hardware I could get to work with Direct TV? Also, I'm not sure of what all is possible as far as integrating the two. If there is a guide, please let me know. Also, I would love to hear from anyone who is able to network or use Ubuntu with Direct TV.
Version: 11.04 (At least that's what the About Linux file tells me)
Graphics Card: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)
System: Dell Netbook. Nothing remotely fancy.
After a night of trying to adjust the graphics settings to work with a reasonable game, I powered down for a few days and went hiking in the woods. Never got the game to work, but I had no problem restarting X and continuing to work. Thus, I assumed nothing was wrong. The only real change was the installation of DRIConf. Upon my return, I started up only to see my desktop background image load, and no GUI. No cursor, no Unity, nothing. When I boot up in recovery mode, GNOME seems to work perfectly fine. If I open DRIConf, though, it says that no devices can be found that are capable of direct rendering. My glxinfo output is below (clearly indicating that direct rendering is working). I assume there's a relationship between these problems. I just switched to Ubuntu a few months ago and am obviously a bit beyond my depth.
name of display: :1.0
display: :1 screen: 0
direct rendering: Yes
server glx vendor string: SGI

I have slackware on my laptop but it's pretty buggy lately, and last night it really pissed me off freezing and loosing the volume icon.So I decided to install Xubuntu over it.(Most probably it'll be Xubuntu, 11.04 or maybe Aptosid with XFCE )But - I'd like to try not to format the home partition. Now it's separated. (The partitions now are /boot, swap, / and /home.) So, I plan to:
1. Boot from the USB;
2. Delete all the hidden files and folders from the the /home. So anything that the Slackware has put and/or set - to be cleared.
3. Directly install, keeping the current partitions, but without formatting the home.
The only thing that I think of that could make some problems is that when I booted Xubuntu 10.10 on my working machine - it couldn't mount any of the hard drives? So if this happens on my laptop too.I won't manage to delete all the hidden stuff on the home.
how exactly would you open a port and point it to an html page, like port 80 does by default?
Example: Port 2985 -> ./var/www/login/index.php
Eventhough users know the root credentials how to restrict them from direct login as root user. They can login as non root user first and then as root userthe material or provide some url for learning the perl script.
