I am very interested in using CentOS as a server for diskless PXE booting and was wondering if this was a possibility. I have a working DHCP/TFTP/HTTP system set up and going and I can get my client machine to boot a linux image without any problems. Ideally I would like the diskless machines to be able to immediately load an image through PXE and store their own filesystems on the server through the use of NFS.I heard about system-config-netboot and got very excited because it sounded like something that would help me set up a diskless system. However, after doing some research I have heard from many that it is generally buggy and unlikely to work. When I tried using it I got the error: "The diskless directory must be NFS exported and contain a boot sub-directory"Even though my diskless directory WAS nfs exported and most definitely contained a boot sub-directory. Does anyone have any advice on using this tool, or using CentOS as a server for diskless clients?
I'm installing CentOS for the first time to run mythtv on (I previously used Fedora, but the new version cycle was too quick). As part of the instructions I'm using, I am told to run system-config-boot (to ensure that centosplus kernel is loaded on boot). The problem is, I cant find this option in my installation of CentOS. Another option I have is to manually edit the grub.conf file, but I'm not sure exactly how I should edit it.
system-config-samba doean't work from terminal neither it is shown in graphical mode, i cannot see system > administration > servers. Server is missing.
I trying to set up a LDAP server using openLDAP / db4. The server runs fine but I cannot get the client to work. Client and server are on the same machine, as for now. The problem seems to be in PAM. However I cannot start the system-config-authentication tool which should do the trick.
I have a Samba File Server that can authenticate users in my Windows AD to log into the server. Anyways, I have a good amount of Windows Admins on staff but our org wants to cut budget so our first "slash" as it were is cutting down the actual Windows based File Servers.So my question is, now that I have this test server up and authenticating for logins using Windbind....is there a way I can get system-config-samba to "see" winbind users and groups so that file servers can still be "point and click" for my Windows Admins?
I'm trying to compile a program from source. When I run make the following appears:./ config. status --recheck make: ./config.status: Command not found make: *** [config.status] Error 127.There is no file called config. status in the current directory. Why was it not created?
I am a long time Unix system admin and this one has got me stumped.When I try to run the system-config-network (or any of the system-config-xxx programs) from the links on the GNOME interface, I get a message pop-up that says, "Unknown error" and no additional information. I have also opened a terminal and run it from the command line (/usr/bin/system-network-config) and I get the same "Unknown error" pop-up. I was not the one who originally configured this server, so I am not sure of the history or how it might have been broken. I can't seem to find any debugging information or even any command line parameters that might give me a clue what the complaint is. There is no error number or any other helpful hint as to the cause of the problem.
I have been manually editing the config files so the server is up and running but it is tedious to manage the server without the GUI.Has anyone seen this before? I assume it is a configuration issue, but I am not sure where to look.uname -aLinux xxxxserver 2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux/etc/redhat-releaseCentOS release 5.4 (Final)
I've tried to read many of the topics in this forum first and tried to find a solution to my problem, but can't find one.I'm testing CentOS 5.5, it's the first time I'm using a CentOS Linux release.I'm trying to configure the proxy "client side " on it and cannot find how to do it.On other Linux release I've used the ENV variable like "http_proxy" or "HTTP_PROXY" etc etc.This time, I don't know why but it doesn't work.I've put the name and @ip of the proxy in /etc/hosts and tried different version upper/lowercase of "http_proxy" "HTTP_proxy" "ftp_pr.." but it doesn't work.If I configure manually Firefox and puting the name or @ip of the proxy we have on our network, it works.But if I try to use ENV variable it doesn't work...
I have been trying to install Ubuntu by network booting, I used tftp in Windows in another pc, and the target boots successfully but fails to download from any archive mirror, I'm not sure what goes wrong.
Well, I'm trying to do is, my friend's HP-mini fails to boot to Windows, and BIOS also gives error-messages, the thing is that my friend has important data on his netbook, it has only one drive, no cd-rom, and it doesn't support USB-booting, so I was thinking if I get to access an Ubuntu, I will be able to backup his data and install Windows, I would use anything that would let me copy files.
I have a bootable usb stick with a Linux utility on it. After poking around for a bit I figured out the boot order:
isolinux.bin <--reads isolinux.cfg loads the kernel: SA.1 loads initrd: SA.2
then depending on the options you select it boots one of two .iso files I want this utility to netboot instead of booting with a usb stick; is there a way I can package isolinux.bin, isolinux.cfg, the kernel and initramfs, iso's and all the other files on the root of the usb stick into one iso that can be tftp'd to the host which would then boot something that would extract the iso to ramdisk and start booting so that isolinux would run as if all the files were locally stored on CD/usb stick?
after the third time downloading the netbook and installing to sd and or usb i decided to check the md5 but where is the md5 the new download pages bites.. wheres all the mirrors/ the new desighn is a good at waisting space //wheres the md5? bring back ftp style downloads?
I am attempting a netboot installation and I aw following the documentation found here My problem is that given my dhcpd.conf I am met with the errors listed below. I have checked to make sure that none of the conditions that the error warns about possible causes are currently in effect on my system.
I tried to build a HP DL380 today, and the drive wasn't detected. Suspecting hardware issues, I tried it on a 360, same issue. We built these machines before with no problems I used the 8.10 install on our PXE server, and it worked fine. I suspect it's related to the upcoming 8.04.4 release, perhaps a new kernel has been inserted and has missed the cciss driver? Booting using 8.04, and running find /|grep cciss, doesn't find anything. I can't remember the last hp 8.04 build I did, but it was in the last month or so. Doing it with 8.10 finds the driver. (this is the 32 bit install)
I have just installed ubuntu 10.04 via a netboot install.When my system reboots I only have the command line - no gui. Could someone kindly inform me what command I need to run in order to get a GUI
I am trying to use netboot functionality available in GRUB(legacy). I just compiled GRUB with --enable-diskless and --enable-rtl8139 options and installed in USB flash drive. I am getting the grub prompt when tried to boot from that USB. But not getting boot command..what i need to do to enable boot command??
I have and embedded system which apparently, due to space considerations, is missing lots of normal commands. I can get the following information by "cat /proc/version":
Linux version 2.4.19-uc0 (...) (gcc version 2.95.3 20010315 (release)(ColdFire patches - 20010318 from http://fiddes.net/coldfire/)(-msep-data patches)) #461 Tue May 24 12:06:06 PDT 2011
At issue is the fact that, after some time, the system stops responding to the Network (e.g., you can ping it, then some time later you can't). We suspect that some sort of network monitor is accessing the device and causing the trouble, but don't know for sure.
What I would like to do is log some sort of useful network status information and/or be able to reset the network if I can figure out there is an issue from within the device.
I thought I had it all working using "/etc/init.d/network restart" but I've come to find out that the command is not recognised in this system. I also can't issue a "top" command to see what services are running. I can Telnet in, so I can try commands and see if they work.
Have any of you worked with such an abbr. system and if so, what might be around that I'm unaware of to help determine network status?
Actually I suppose to use this "htop" command to get the system utilities like current processor speed ,running programs ,memory usage(ram and swap) to my program. I planned to get it using popen(). I was success popen("top | grep Mem", "r") with top command. But are there a way to take such information using "htop". Or are there any idea of taking current CPU,MEM,Swp usage as well as Tasks and running tasks using htop or other way to C program...
Crashed System left at root @ maintenance shell. Below is the sequence after boot, with Exact Errors. How to Salvage important files from my crashed laptop hardware. A) Via a Transfer to a USB stick in Terminal, would be ok B) Via SSH through the router from the good laptop that is Preferably using Nautilus / GUI, Terminal also ok (less confident of my skill here) C) Directly Fixing Laptop and being ably to use Nautilus / GUI to Copy Files to USB stick, localy
The result of some effort: A) the USB stick is good but Can't get in to it from the crashed laptop B) SSH: No luck I get: "Cannot display location "sftp://192.168.1.101/"" from the good Machine C) at a lose here...

I was puzzling over the nss dependence problem that people are having in upgrading 5.2 to 5.3. The issue is clear (that the mirror people are using for [updates] is not pointing to the latest set when an uptodate mirror may be being used for your [base]). My question is though how the mirror list decides whether a mirror is fresh. According to [URL] then this mirror [URL] is "green" which presumably means that the system thinks it is up to date (last probe was 1 hour ago). However if you look at the files on the mirror now (12:54 BST, Apr 1 2009) you see that the date of the 5/ branch is 24-Jun-2008. Thus this host is not ready to give you updates to 5.3. Is this a bug?

I have just upgraded to Lucid on Ubuntu. I am a long time Pidgin user. I tried using Empathy with Gwibber, but I can't get Gwibber to update my IM status(es) in Empathy, so I want to go back to using Pidgin. (Additionally, I can't get Skype to work with Empathy.)I installed pidgin-microblog and pidgin-mbpurple, and they allow me to view my Twitter feed in Pidgin and update my Twitter status in Pidgin. However, in Karmic, I was also able to specify certain "status availabilities" (one named "Twitter-Available" and one named "Twitter-Away", for instance) to have the IM status message for these statuses become populated with my Twitter feed. This capability seems missing in pidgin-mbpurple in Lucid (and it seems to be the only thing missing from Karmic).
Is there a way to have pidgin-mbpurple update certain "status availabilities" in Lucid (and I'm just missing something) or is this no longer possible?Equivalently, is it possible to have Gwibber update my status message in Empathy? (I just want to be able to update my status once on one of my three computers - and have it propagate to all my other accounts (IM and social networking) and computers).
when I try to apt-get upgrade system or install a new package in synaptic or terminal, I see this:

I installed Documentum content server on CentOS my OS version : Linux cserver 2.6.18-8.el5 #1 SMP Thu Mar 15 19:57:35 EDT 2007 i686 i686 i386 GNU/Linux. I could successfully install the software but when I am trying run any executable I am getting the following error message.

Above ./idql is a executable came with installer. how to solve the problem, I am sure it is due some patch or hot fix of OS, I have similar kind of problem on Solaris.
I installed slackware 12.1 from files i downloaded and converted to cd (images). There are six "disks" i downloaded from the slackware site and converted to images via a homemade .cmd in windows xp and then burned using imgburn.
I partitioned my hd (canibalized from an acquaintance's emachine and connected it to my desktop (1G ram, 2Ghz processor). Booted from disk 1 and fomatted the 80G HD for 2 partitions of linuxswapable at 2G apeice and 2 partitions of bootable linux. (Because i want to try another distro later). I ran the setup installing most everything and all seemed to go well. After i exited setup and restarted, it identifed the cd/hd as normal and then went into some sort of recovery mode with the emachine logo call pcangel, after which it tells me.
STOP: c0000021a (fatal system error) The session manager initialization system process terminated unexpectedly with a status of 0xc000003a (0x00000000 0x00000000). the system has been shut down. So, is this indeed an xp error message, and if so, why am i getting it after formatting everything?
My machine is a new Fedora Core 12 install. The install did not make an /etc/x11/xorg.conf file by default, which is odd. So, I want to change things with the display. But there's no "system-config-display" in /usr/bin. What's going on? Why wasn't this installed by default? I've had lots of other problems with X on this machine as well:
the 10x20 fonts were missing XFree86-Misc error messages whenever I start an xterm I also receive these warnings, intermittantly, when I create xterms:
Code: Xlib: extension "XFree86-Misc" missing on display ":0.0". xmodmap: please release the following keys within 2 seconds: Control_L (keysym 0xffe3, keycode 37) xmodmap: please release the following keys within 4 seconds: Control_L (keysym 0xffe3, keycode 37) xmodmap: please release the following keys within 8 seconds: Control_L (keysym 0xffe3, keycode 37)
With this many problems I want to know if there's something in general broken with X on FC12, or was that just my install, or what?
