I have just build a new computer, and I want to install Ubuntu 10.10 on it. The problem is that when I run the Live cd and start the installation it cant find enough space to install. I have a 1TB WD Black Caviar disc installed and I can see that the BIOS detects it.
View 3 RepliesIn a 32-bit system, max memory addressable is 4GB. Now Linux kernel does memory mapping division of 1GB for kernel address space and 3GB for user address space. That means 4GB of virtual address space is divided between kernel (1GB) and user (3GB).
Q1. All virtual mapping utilizes the available physical RAM without any division? I mean to say that if RAM is 512MB then a page in kernel space can lie any where RAM (leave aside old PCI dma accesses)? (How this fits to fact that kernel memory is non-pageble)
Q2. If a process is created in user space, it has visibility 4GB address space or 3GB address space?
i just got my iphone ,and as we know it is asking me to connect to itunes for the start up process ... so what should i be doing ? i got wine just installed itunes 7.2 ( ya is a old version but some 1 ol suggested it will b better , i did it ) anyways coming to the point , i c itunes is having some problem,as it is hanging and not working i thought it would .so is there any ways i can install itunes , and will give a better performance
View 2 Replies View RelatedI downloaded Ubuntu 10.10 and made created a DVD. When I started installing it, I'm not able to do it. I think its hanging. This is what happening: First I found a screen saying 'ubuntu 10.10' and it loaded for some time then I got a screen with a black color task bar at the top of the screen, then after some time it turned into white color and after some time it disappeared. Nothing else happened. I didn't find any pop-up window to start installation of OS..
But when I tried this in my friends house, I found that instead of 'ubuntu 10.10' there came 'Ubuntu' LOGO and it was little bit slow but a pop-up window opened to start installation..
Why its not coming in my PC..
my computer configuration :
Windows XP, SP 2
256 MB RAM, 1.81 Ghz
AMD 64 Athlon Processor 1800+
I want to shift my OS to Ubuntu completely.
I had been having problems with every LiveCD after 8.04.1 I tried both xubuntu and ubuntu (same internals, same results)
I ended up installing xubuntu 10.4 using the text mode installer.
The system basically works, I can not get gdm running.
dbus fails as noted above. I found launchpad bug #446971 and tried some of the work arounds with no success.

I'm trying to find how to schedule a process to start at a specific time (not on start up). How would I schedule a process/application to start at a specific time (if it matters, it will be a background process). For instance, have process abc start every weekday at 5am. I've done this for windows many times though have only been using linux regularly for a few months and haven't figured out the best way of doing this.
So far the best solution I have is to create a program that will start on boot and have it check the time and sleep until the required time and then start the required process(es) at the required time(s). But this seems more of a hack since I'd expect there to be a proper way of doing this.
Whether i am short of memory or some memory corruptions? If so, what can i do? Because i find it hard to believe this is a memory problem when i have 4GB of RAM and 6GB of swap space, and my CPU process normally don't occupied more than 30%
Well my Linux is keep on crashing.
Code:
I want to know if i can increase the memory space allocated for a process manually while the process is running ,,,, and if it is possible how i can do this .
View 2 Replies View RelatedSuppose a process creates multiple shared mem segments as part of it job.Now is it always possible that on restart, that process can reattach to those previously created shared mem segments to the same virtual address spaces (returned on first time creation) ? My intention is use pointers over shared memory.So on restart I want those pointers absolute value to remain valid.
View 1 Replies View RelatedFor the past few days I was putting effort on understanding the software control flow starting from "Boot loader" to "Linux User space".
I am consolidating the entire process and putting forth in this forum...It would be great if someone can validate this..It might be useful to other new bees too.
Step 1 : Power up the board
Step 2 : The CPU control goes to EEPROM/storage memory where BIOS resides
Step 3: BIOS gets loaded in RAM and gets executed
Step 4: During execution, the selection of Boot device has to be done with the help of BIOS Menu [Blue screen appearance during start up in normal PC's]
Step 5: BIOS shall access the Bootloader stored in boot device [for eg.,Hard disk]. Boot loader is stored in MBR area.
for explanation purpose I take the following configurations
Bootloader = GRUB
Boot Device = Hard Disk
Step 6: GRUB shall be loaded in RAM and gets executed
Step 7: GRUB shall load the KERNEL image to RAM. Kernel image is stored in Hard Disk.
The question of "How the GRUB knows where the Kernel image is stored".
The answer is
1. In the "Grub.config" file, the location of "Kernel Image" and " Ramdisk Image" [which will be discussed later in the section] is being given.
Step 8: Kernel Image followed by Ramdisk Image is loaded in RAM by GRUB bootloader
Step 9: Kernel Image gets executed...During execution, top portion of the code shall make initial hardware initialization and latter part
of the code shall just decompress the Kernel Image
Step 10 : After decompressing the Kernel Image, it shall decompress
the already loaded Ramdisk Image
Ram disk is just creating a temporary hard disk in RAM. The main responsibility includes it consists of minimal driver files, executables, directory structures to created a TEMPORARY ROOT FILE SYSTEM.
This Temporary Root File system shall be used by Kernel Image
1. Execute the executables to access the Hard disk
2. For creating Permanent Root File System in HARD DISK
Step 11 : Kernel Shall look for the file /Linuxrc in Ramdisk. Linuxrc
is a USER script file [not sure]
Step 12: At the end of script file Linuxrc, the Ramdisk shall give the
control to "USER SPACE" [path for writing the script not known]in Linux kernel
Step 13: USER SPACE is the normal shell
I know that fork() copies the address space of the calling process. Say, however, i have a linked list allocated. Will the list be copied over to the child process's space? If so, i would have to free them in the child process as well as the parent process, correct? Or will the variables be copied but not be pointing to any valid address? Or would it just kind of not do anything?example:
Code:
struct ll_ex {
struct ll_ex * next;

View 1 Replies View Relatedubuntu 10.10 At times something starts thrashing the HD. Often after the computer has been taken out of Suspension. The whole things slows down and stays slow. This can be fixed by logging off (which takes quite a while under this condition while the HD light stays on, solid) and logging back on. Then the system becomes responsive, with only HD light flickers. Anyway, I can't determine what process is doing the thrashing. System Monitor doesn't show any memory problems, and neither do top or htop. htop shows plenty of swap space available, and memory usage is on par with what it looks like when there is no thrashing. Is there some tool that can display what processes are running the HD so hard?

View 3 Replies View RelatedI have googled this and I refuse to believe the answer is "older video card" or "ubuntu". Does anyone know what boot parameters to use or how to get Fedora to start the install process in a resolution other than the "Optimum resolution"? resolution=640x40 vga=ask. These do not work. They set the debug display but when the graphical portion starts it defaults to the "optimum resolution" and the message displays "Cannot Display This Video Mode". As you consider the answer, think this is a new computer, blank hard disk, etc. I am installing Fedora 10. Tried 11 and Vista seems less buggy, prefer 10 or 9.

View 7 Replies View RelatedWe are having a Linux box with Tcpdump continuously running on it to monitor bunch of sources. Separate Tcpdump process runs in a background for each host for monitoring traffic. I use -w option with it to save the capture in the pcap format to analyze it later. Now what I need is, if the Linux machine gets rebooted amidst of its packet capturing activity, I want tcpdump to automatically start the process again for every host without overwriting previous captures.
Remember: Without overwriting previous captures . . .
Basically, I will be keeping all the tcpdump commands in the shell script and will load the script at startup during the linux boot. Is there any way to achieve this case, where by on rebooting, Tcpdump does not overwrite previous captures?

this is not specifically a slackware related question, but since done on 2 slackware boxes... the situation is, i have one box for browsing and other desktop activities and another box acting as router/local server. what i want to achieve is that the router box would look on a nfs mounted folder for new *.torrent files (which i put there from the desktop box) and if there is a new file, it would start downloading it automatically. also a good thing would be if it would notify me when finished.so how would you go about itwhat torrent client would you use and so on? maybe someone has already done something like this?
