i have a own internet cafe that use a Fedora Core 8 as a dhcp and proxy server, and i had two normal users that created in my server to monitoring the billing of client who use the internet. But was delete those users and create a new one and restarted the server. and the problem is when booting process running suddenly hang and cannot continue but the server doesn't showing any errors and cannot continue the booting process.....
I am in school for my CIS degree and the book I am using this session covers Windows XP and Fedora Core 4. I am having trouble finding & downloading Fedora Core 4. My question is: Is there a big enough difference between Fedora Core 4 and Fedora Core 14 that I would not be able to use 14 instead of 4?
I recently setup an email server on Fedora Core (14). Sendmail is running and I am trying to authenticate from a client pc using imaps. I installed Cyrus-imap and it is running and listening on 993. When I try to login, it doesn't accept authentication even though I verified the user's password is correct. (tested with ssh)Is there something I have to do with Cyrus or on the server to allow connections to email? I have not used Cyrus before. I am attempting to access my mail folders via Sendmail and did not make mailboxes in Cyrus. I did allow imaps through the firewall.
We're running a sendmail server on a fedora core 9 which we've configured recently. The problem is, the server is working fine but there are some e-mails that enter our server but doesn't get forwarded to the user.

I am attempting to use a PXE and nfsroot to boot fedora core 13. When my virtualbox image boots, I get the following error. view the screen shot.I have the following entry in my TFTP entry to boot this system:
Code: prompt 1 default linux timeout 30 label linux kernel vmlinuz_fc13
I'm running Linux on an Intel Core 2 Duo processor. When I apply power to my computer, it boots into one core but appears to leave the other one idle. On the screen, it prints:
.... SMP: Allowing 2 CPUs, 1 hotplug CPUs .....
I can confirm that only 1 CPU is active by logging in and examining /proc/interrupts and /proc/cpuinfo. After issuing a "reboot" command, the screen shows:
... SMP: Allowing 2 CPUs, 0 hotplug CPUs ...
So, when I do a cold boot, I one get 1 CPU. When I do a warm boot, I get both CPUs. This is a problem for me because I'm running Linux on an embedded board and I need both CPUs to be running.
I've played around with BIOS settings, the boot string, kernel configuration, and CPU hot plugging. I can't seem to find a way to get both processors running without booting the system twice.
I thought that the CPU hot plugging path showed some promise but I can't seem to get that feature working on my system. The first issue is that the Linux documentation doesn't seem to match with what I'm seeing. It states that you should be able to go into /sys/devices/system/cpu/cpuX/ and write a zero or a one to the file labeled 'online' to disable it or enable it. When I go to /sys/devices/system/cpu I only see a directory for cpu0. There isn't a directory for cpu1.
After a reboot, I do see two directories int /sys/devices/system/cpu (cpu0 and cpu1). At this point, it won't let me 'offline' the second processor. The echo command gives me an error. (By the Way: the 'online' file in each cpuX directory has read only permissions.) This error occurs after I've changed the permissions on the file to read/write.
I confirmed that the following parameters are set in my .config file: CONFIG_HOTPLUG, CONFIG_HOTPLUG_CPU, CONFIG_SMP, CONFIG_SUSPEND_SMP
I've done searches on google until my eyes popped out and can't find much information. I see others have had similar problems but they all seem to link back to ACPI in BIOS. I've already played with all of those settings and I didn't see any effect. One reason I don't think it's a BIOS problem is because a warm boot (reboot) seems to 'fix' it.
I've tried different kernels, different distributions, and different computers. I see similar behavior in all configurations. I feel like I'm missing something fundamental.
I just installed Windows 7 Ultimate on my computer and I want to install Fedora Core 11 and dual boot my system. I have been on the net looking around, but I can't seem to find any suggestions on how I would do this. Can someone help me or give me a URL(s) that will give me a step-by-step guide on how to install Fedora Core 11 on a Windows 7 computer?
I've been using Linux (Fedora) since 2005 (when I happily abandoned Windows) and loved every minute of it. No installation or other unresolvable problems. But now, I am totally stuck. A month ago, they just gave me a new desktop in the office: Dell Optiplex 960 with the Intel Core 2 Duo vPro chip. So I waited for Fedora 11 to come out, burned the x86-64 Install Media on a DVD, repartitioned the hard drive like I always do on new Windoze machines, and began installing. The install process gets to this announcement and stops:
mounting /tmp as tmpfs... done Then, after a 5-minute wait, if I push the power button on the computer for a hard reboot, then it says:
running install running /sbin/loader and then stalls for good. Then all I can do is hard-reboot again.
So, out of curiosity (and for other reasons), I tried booting the machine from other linux disks: Knoppix, and SystemRescue (www.sysresccd.org). They all stall at different points. The funny thing is that both Fedora 11 x86-64 and SystemRescue happily boot on my personal one-year-old Lenovo T61 Intel Centrino Duo VPro laptop.
I get a feeling that somehow the Intel Core 2 Duo vPro is causing the problem. I also think that there is got to be someone else out there who either had this problem, or was able to install F11 on similar Dell box. Google search did not produce actionalbe answers for me.
I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.
I have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?
I have an HP Pavilion m7480n PC with Windows XP installed on the C-drive. I successfully installed FC 12 onto the spare USB drive. When I rebooted the PC all I got was a blinking underscore at the extreme upper left position of a totally black screen. After a bit of experimenting I found that if I hit the F1 key during the boot process, go into the BIOS setup, do nothing within the setup, and press ESC to get out of the setup then the PC will go back into the boot cycle a second time. During the second time however a small text message appears with words to the effect "Press any key to enter GRUB..." after which the GRUB splash screen comes up with the choice for FC 12 or "Other" (referring to Win XP). At that point I can boot into either one.
Here comes my problem: I am installing a new unit with Fedora Core 5,I will use it as my internet server. I need one additional PCI network card but it is not detected during installation.what shall I do?
I've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?
Im trying to dual boot windows xp on my computer already running fedora core 6. I have some experience with dual booting- i had a windows xp laptop, and now it runs both windows and ubuntu. Ive done some reasearch, but still not clear on how exactly I should go about dual booting xp on fedora.
I forgot to mention above I do not have internet access on that computer. I do, however, have a laptop (windows xp) that i can download things on and burn on a disc if needed. it has internet. If you know of any solution to run programms such as visual studio and dreamweaver on linux which dosnt require dual booting(i tried wine but didnt work for me)
I need to upgrade one of our systems from its current distribution, Fedora Core 7, to the most recent version distribution, release 5.4, of the CentOS operating system. Can I do an in-place upgrade of the operating system without any adverse side-effects? Are there any issues that I should be concerned with before proceeding?
This is my first post and I figured why not start it off with a question! First off, thanks for this site, I have a LOT of reading to do!
Secondly, my question is, what is the easiest way to upgrade my live server from Fedora core 4 to Fedora core 14 (latest stable version).
I have a box that is live with a couple of small active forums on it where the upgrade would take place.
I want to upgrade my box to stay up to date with the latest release of Fedora linux to take advantage of any enhancements or security fixes that has been implemented since version 4.
My box is colocated at a data center. Would it be best to upgrade from a CD or remotely? I have read there is quite a risk upgrading the OS remotely and some issues like broken files or dependencies could occur.
I have been sat in front of this PC for hours now trying different ways to get Fedora Core 12 to automatically login. This hangs it up at the splash screen
After login I get the blue desktop with the swirly art thing but I don't have a starting point to be able to do anything and think screen resolution may be the issue. How do I resolve that?
just did Red Hat Linux (Fedora Core 2) install. It's the only OC on the machine. Boots and everything seems to work just fine. Everything but the operator, that is!
I want to install FireFox and Thunderbird and AVG (free) antivirus so I first went to the Mozilla site for a download, only to discover that the best way to install is as part of a Package Manager.
Fair enough - but what is a package manager? Part of the distro? Where do I get one for these items?
UPDATE - I figured out the Package manager thing and no , FireFox is not an option, nor is Thunderbird or any antivirus.
If I can't get a package manager, the site tells me that I can install with me as the only user by downloading and typing in a couple of commands (Unzip and run, I think). But I get a report that I need a something or other file (library?) for it to run. How do I find that file and why would I be the only user? Surely as root I can set it up for all users can't I?
I guess the short(er) question is: How does a new user download and install a program onto a new setup without a package manager?
Question 2 - this install is for a class and the instructor wants screen prints as proof I'm doing certain operations. How do I get a screen print of, say, a history listing and can I save the screen print or view into a file for submission?
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
