CentOS 5 :: IP Configuration Lost After Reboot / Get That Back?
Sep 16, 2009
Google brought me no love on this one, tried searching here with little luck as well. So I'm hoping somebody vastly more experienced than I can shed some light on my plight.
The situation:
I have a CentOS 5.3 x64 server running the latest cPanel which works fantastic. I issued a graceful reboot and the server came back up (according to the DC) just fine to a login prompt. Apparently the system lost all of its IP address configuration. Primary IP, secondary IP's gateway, you name it and it was gone. Now my secondary IP's were showing in cPanel after I had the DC re-enter my main IP address/gateway. But listed as not active due to the fact that they were not anywhere to be attached to the interface. i.e. eth0:1 eth0:2 etc and so on.
I have no idea where to begin looking for this problem and am afraid to reboot it again (at least until I get my lantronix spider up there). I've never experienced this with any of my other CentOS/cPanel servers either. All similar configurations CentOS 5.3 x64, latest cPanel as well. My hardware is all Supermicro gear as well and has been solid in the past.
Maybe I'm just missing something, granted I've only been managing Linux based servers for about two years now. This is actually the first real problem I've ran into on any Linux distro, they are normally pretty solid. So I assume it's a configuration error on my part somewhere.
after a reboot of my Lenny system, the default gateway will lost. Then i must try "networking restart" and the gatway will be set
my interfaces looks :
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback
I have a problem with a few up-to-date installations of CentOS 5.5. I have lost all md (software raid) devices on them some point in the past. They were working ok.
Now the 2 disks are seen as two separate disks, with no link between them.
I had Oracle install on my machine and there were some ASM partitions. after uninstall of oracle some how it removed the swap space and now is showing:
I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.
I have entered my primary and secondary DNS addresses through Network Configuration tool (system-config-network). But whenever I reboot the system it loses the DNS addresses. Following another thread, I tried changing the PEERDNS=no in ifcfg-wlan0; but it didn't work. I also put both DNS addresses in the ifcfg file, but that didn't work either.Does anyone know a solution to this?$ uname -aLinux fedoralinux 2.6.27.15-170.2.24.fc10.i686 #1 SMP Wed Feb 11 23:58:12 EST 2009 i686 i686 i386 GNU/Linux
I was using Ubuntu 9.10 and was using fireftp ( firefox plugin ) to do some ftp operation. And then I noticed firfox is fozen so I reboot my pc by switching off the power ( restart doesn't work ). When I turn it back on again, no GUI anymore. I was taken to ttyl login commend.
I installed Kubuntu on my Toshiba A135 with no problems at all...everything works: sound, wifi, LAN, etc...BUT whenever I reboot/restart the computer my Display and Audio settings revert back to default, and it doesn't happen when I log out, just when I restart/shutdown the computer. I have an Intel 945GM chipset and I have set my external Acer 23" monitor as the default and only monitor with a resolution of 1920x1080@60Hz using KDE's System Settings...And I chose to disable the laptop's internal monitor...but whenever I restart, the display returns to a 1024x800 cloned resolution (the default one)...which by the way looks hideous on a 23" monitor. And also the sound mixer goes back to the default levels.
So, can anyone help me out? I've been using Ubuntu for over 3 years and I've never had any problems like this one. I have just fell in love with Kubuntu, it looks and runs great, but this problem/bug is keeping me from being comfortable with it... I've been reading some things about XRandr and some commands and stuff and nothing have worked until now. I wonder, is it a common bug in Kubuntu or maybe an erroneous setting in the session manager....?
I run OpenSuse 11.4 with KDE 4.7. When I change the positions of icons in the main plasma panel, or reshape folder view plasmoids on my desktop, these changes are lost when I start my computer the next time...
I have a problem with klipper hotkeys. On reboot, they are saved in ~/.kde/share/config/kglobalshortcutrc but don't work anymore. they are visible in "system settings > keyboard and mouse > global shortcuts" in the klipper tab, but just wont work. However, they are not set if I try to access them by klipper menu "right click > configure klipper > shortcuts" It seems that shortcuts aren't even noticed by kde : xev's output from a successful shortcut ( alt+g) (notice the focusout/focusin instead of the keypress):
I'm running PCLinuxOS 2010.07 (KDE) on my Acer laptop with Intel Mobile GM965/GL960 Integrated Graphics Controller. I have an external Acer monitor that displays at 1920*1080. I have selected my laptops internal screen to be disabled and use the external screen. The PC LinuxOS Control Centre selected the 'Intel later than 810 driver'. All works well whilst I'm using my system but when I turn off and reboot the settings are lost and I have a 1280*800 display on my laptop and the same on my external screen. Resetting the Display using Configure your Desktop allows me to reset the external monitors to my preferences but how can I make theses settings permanent?
I running Ubuntu ver 9.04 I have 2 problems that I think are related. After finally making a network connection I updated Ubuntu, and after a reboot I lost my network connection again.I updated the following file nm-networkmanager-settings.conf and saved it. After another reboot I then lost my network connection icon and it also does not appear under System > Preferences. I tried to then update the same file and can not save it, I get "could not save file".I have tried sudoedit, sudo gedit, gksudo gedit and some others that I cna not remember now and all give me the same result
I was trying to free some memory as my /var was about to fill.I went to Add /remove software and ried to remove some of the unwanted software and it asked for dependency and i clicked ok.After a while i saw some of my aplication like Evolution,Empathy blackening and i killed the Uninstallation. I was sure by time that something wrong has happened and i did not switch off my monitor so that i can retain my application.I tried lot to increase teh /var so that i can update my yum and install some lost application but allin vain i tried Gparted which can only decrease the size . I had 40 GB unallocated space so i tried to boot from Live Fedora 12 DVD and was able to see my all the files and filesystem. All my data in /home was intact.I tried to go to grub and went to boot hte kernel and Initrd and was able to go to #root but again was not able to update the system as network was missing.The SYSTEM was Not booting and stuck in between. Tried to change the /var to var1 copied /var content to /var1 and made changes in teh /etc/fstab still did not work ,so finally went to repair with Live cd but could not get "Linux rescue" anywhere not even to upgrade option so finally installed the New linux without touching / and /home partition rest were deleted and formatted for new instalation.Now i could not see my data in /home directory although i could see data in /root(old) and all ..i am now lost ..my data is nowhere ..please help me.I can only see /home(old) but it says empty and shows 6 GB unused and 3.3 GB used when seen in Gparted .
I shut down my laptop this morning and headed to the office and fired it back up to find that I no longer had the use of any of my usb ports! messages are saying that the ports have been disabled. curious if an update broke something? the ports have been working fine, I use a usb mouse instead of the touchpad most of the time.
Today I removed my panel at the top of my screen by mistake. The panel showed open programs and my firewall icon, which I liked. Does anyone know how I can get this back up please?
Alright so I lost a sd card that I had uploaded to my comp before it crashed but I wiped the card before I lost it and I want back what was on it..I have ran testdisk and photorec and it has only brought me back 5 or so pics, but when I search the card in deleted files through either program it lets me see the file names, and when I try to save it the computer doesn't read the jpeg file when I go to open the recovered file.
I've installed Fedora 12 KDE using VMWare, but I can't for the life of me get my display settings to stick. When I change the resolution, my display responds appropriately but upon logging out or rebooting, these settings are lost. Am I missing something completely obvious here?
After I installed the new Fedora 13, all went well without problems.
Unfortunately, the sound settings are not retained. That means after a reboot, I have to set this again and again.
I have an: HD 5.1 Intel OnBoard Sound Card. I run "gmix" or "kmix", the rear wheels boxes are always "mute". I put on this, but after the restart the setting are lost.
The PulseAudio settings are set to 5.1 Digital Sound.
What can I do to go the the settings are not lost?
I have just upgraded to Lucid Lynx. Just after that the borders of disappeared. Anyway, I found out I can get them back if I enable Standard Visual effects from the appearance menu. The only problem ?i have is that the options don't get saved and I need to do this over again every time I reboot.
I encountered problem on my NEW PROD box. I have remaining space of 300GB and i decided the create a /dev/mapper/VolGroup00 using Redhat Gui. It is successful. Then, i decided to create logical volumes out of it..
I am happy with ubuntu it's cool, but I want to go back to windows. I lost my windows cd. So I made a blank disc with an iso file. But the problem is. When I try to keep it inside my computer and restart it won't load. I think grub has something to do with this.
I have a harddisk which is partiotioned in C & D. I've installed WIN XP on C and WIN 7 on D. Then I installed Ubuntu 10.04 on D beside WIN 7. Now I can't access to WIN 7 and also to drive D in XIN XP and in Ubuntu. What can I do to get back WIN 7 and drive D ?
Login in problems: I was trying to fix the brightness on my toshiba T130 Satellite laptop and found these instruction [Note: I did not try XRANDR option] If backlight control doesn't work with the 'XRANDR' option above, use this code...
Safe the file, run 'sudo update-grub' and reboot.
Credits: https://bugs.launchpad.net/ubuntu/+s...id/+bug/392948[/INDENT]http://www.linlap.com/wiki/toshiba+satellite+t130 However after running these instructions and rebooting my laptop I lost the GUI, and do not know how to get it back. If it helps the loader screen with the 4 dots has gone slightly skewed, and I've downloaded the most recent update changes.
I can get GUI through recovery mode and running it in failsafex, but I don't think this is a good solution.
I'm using Windows 7 and Ubuntu in two differents partitions in my hard drive. I was on Windows 7 and decided to reboot. When the grub screen should have appeared, instead the computer rebooted itself. It continues to do so. I put Ubuntu 10.10 Live CD and it keeps "loading" forever, but doesn't hang. In the console, it said something like "input/output" error. I tried with my Win 7 DVD and it was the same: it doesn't reach the part where it shows the menu with all the installation options.
I tried with Gparted and it loaded fine. It showed all my partitions, but there wasn't (I think) more that I could have done with it. I tried then user Super Grub Boot. I finally could enter Ubuntu. Everything is fine except that it doesn't show my Window partition. It's like it doesn't exist anymore, so I can't backup my files. Now, I haven't tried loading Win 7 from Super Grub Boot (I'm going to do it just as soon as I post this), but this is pretty weird. Anyone have any idea what is going on and what can I do to this this?
I had everything backed up so it is no great disaster, but drop box lost a lot of my files. Some of the folders with missing files now have thumbs.db in them, but when you go to the dropbox site, you don't even see that.
I had thought about using dropbox as my main backup solution. That would be a big mistake.
I installed Ubuntu 11.04 on a usb stick and have been running it from there. I was messing around with the "Login Screen" utility and changed the session choice to "User defined session" (or something similar). I thought this would allow me to pick the session to use (Unity, Gnome) but that was wrong. So right now, when I login, I have a blank screen with no menu bars. If someone could give me the commandline command to run the "Login Screen", I should be able to switch it back.
I was running a patch of my wifi connection and now i have NO wifi at all. I am totally lost right now. i have been running throught all the threads but nothing is really working. Is there a way do a full system restore (like windows) that will undo all my mistakes? my wifi has always worked until i screwed something up!
