General :: Changes To /etc Files Revert Changes After Reboot?
Nov 22, 2010
I've been messing around with a Verizon Hub trying to see if I can get it to register with my Asterisk server. I have been able to telnet into the phone with the root username. I can change files in every other folder on the device except in the /etc folder. I have tried mounting many different ways, changing file permissions but everytime I change the file and reboot it goes back to its default configuration.

I have a working RHEL in /dev/sda1 and a newly constructed Ubuntu Lucid in /dev/sda2. I'm going to edit the grub config and reboot the server into the new Ubuntu. However, I'm not 100% sure that the new distro can boot. And since my only way to access the server is via SSH, I need the network to be up too.
How can I configure Grub and Ubuntu so that if the server fails to boot, it will automatically reboot into the old RHEL? Currently using GRUB 0.93, but I can upgrade it if needed.
Update: In the end, no boot failure occured. But without the insurance from this, I wouldn't have attempted [URL]..

I am using sda1 as /, which is a bootable drive. I do not know if my problem is that I did not create a /boot drive. After removing the iso dvd, I tried to reboot and I get this back: -bash: /sbin/reboot: input/output error Then it returns me to the terminal prompt.

When I connect to my linux server via FTP, my base folder upon login is not my user home directory, but instead '/www'.'/www' belongs to user root and one of the secondary groups for my user account.I am connecting via SFTP, using my username/password, and without setting any default root directories. I get the same behavior in multiple clients (Dreamweaver/Cyberduck), both active/passive connect modes.

I upgraded U. 9.04 to 9.1 over the net a few days ago and got stung by the 'Driver' issue. Namely, my nvidia card is not reconciled and as a result, the monitor remains blank. I am assuming that the remainder of the upgrade went o.K. though I can only follow the boot sequence on the monitor during the bios start up.
I have a live disk of U. 9.04 and want to revert back to it, preserving my data. When I put in the disk and am hopefully asked if I want to "Upgrade", will it work in reverse, so to speak. I understand that there is a problem with compatible libraries etc. but will it ignore this and simply replace the new with the old?

I had a desktop pc running XP home, my daughter has an Acer Aspire 100 running a Linux OS which developed a problem so I attempted to create a recovery disk from the supplied DVD onto a memory stick via my desktop PC. It transpires that the recovery wasmade to my desktop pc in error and now my desktop does not boot up at all. Is there a way to remove this 'recovery' at all and revert back to XP??

A short while ago and for no apparent reason, my system rebooted. I was doing a lot of things at one time scanning, Photoshop in Wine, Open Office, ftping etc. I can't remember ever having this happen. When I logged in again, the window manager wasn't working quite right. That made me think Compiz might be the culprit. Logging out and in again set things right.
I started looking in log files to see what happened but was quickly overwhelmed. Are there any likely key words I could search for to track down the cause? And in which files?

I setup the chromium browser to come up in kiosk mode in the startup applications and after rebooting it does not come up in kiosk mode and the startup application entry is now gone.I have several machines and though they all have the exact same hardware and software, some lose the startup application entry on reboot and some do not.I was wondering if anyone might know what is going on and what might be the fix for this. I don't think it is a chromium problem, but I am positive.

We are running SUSE 10 SP1 and MySql 5.0.62 with heartbeat configured cluster attached to a SAN and after upgrading powerpaths on the fiber switches we had to reboot the machines and remount the SAN luns.
The cluster successfully started and was working fine for about a day or so and then i logged in as root and hosts, fstab, known_hosts were all giving me this error when i tried to modify them "W10: Warning: Changing a readonly file"
I failed over to another node and same thing happens on another node. I can't modify any of these files

Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

I have a Logitech marble mouse (trackball, https://help.ubuntu.com/community/Lo...arblemouse_USB) which works great under HAL in Ubuntu 9.10. For me it is simply not as usable without HAL, because it doesn't appear to be possible to have a button assigned to more than one thing.
With HAL, you can click the back button on the trackball to go 'back', e.g. in Firefox, Nautilus, or you can hold down the same button to use vertical and horizontal scrolling with the ball (as opposed to the normal mouse movement when the button is not held down). You can also get a 'middle mouse' press by clicking both left and right buttons at once. restore HAL to the boot process so I can regain this functionality? Or is it not possible? It would be just as good if I could get this same functionality without HAL, but I don't see how that can be done using xorg.conf.

I installed the new version of Chrome yesterday and all of the fonts are way too small and the pages don't look right at all. I tried doing the page zoom, but that makes the pages look even worse. Has anyone had the same issue? Is there a fix? Is there a way to revert back to version 5?

Since the last kernel update to 11.2 64bit portions of my video does not work right in windows XP running in either Vmplayer or Vbox. The effect is felt with my Webcam - picture is either garbled or blank not responsive at all. all other video functions in my VM's and Suse seem OK! can I revert or set my kernel back to its prior state? If so how? Also I have both "default" and "desktop" kernels - the problem is the same in each. If I can move the kernel back to its state prior to most recent update can I do it to just one of the kernels to see if it solves the problem?

After much pain I finally got a fairly good install of 10.04 (apparently due to my large disk earlier versions like 9.1 are a no go on my machine a Gateway mx6028 laptop with a new 160 gb drive.) I bricked the machine several times applying the bulk auto updates after the initial install so this last time I applied the updates in smaller batches,, I believe the problem is associated with some of the open GL stuff,, any way to
A) go back one update??
B) anyway to permanently mark an update to never come in?

In an attempt to correctly play Half-Life 2 in Wine, I installed the AMD driver downloaded from their site.
Code:
sudo sh ati-driver-installer-11-4-x86.x86_64.run
Reboot. Now, with both FireGL and this running a conflict is created. Naturally the system boots into command prompt. So:

Reboot. Got OpenGL, but performance is choppy. Glxgears is very choppy.So how to revert to the old fglrx? There is an uninstall script at /usr/share/ati. Shall I run that or shall I reinstall all of the above removed packages beforehand?

My netbook has Intel 945GME video, and I would like to use Intel's IEGD to get best performance.
The problem is that I have xorg-server-1.7.7 installed and the latest IEGD (10.3) I can find stops support at xorg-server-1.6.*
If I remove 1.7.7 and install 1.6.99, what else do I need to change? What is the latest 1.6 version available for gentoo? I assume I would have to rebuild x11-drivers/*.

I recently installed an image of CentOS 5.4 on my machine.Through copious yum updates and one kernel update, I now find my /etc/issue says that I am at CentOS release 5.6 (Final).However, I need to be at 5.4, which is why I installed it in the first place. How do I first find out which updates are responsible and second revert the responsible updates?

I added by error a fresh physical volume of a volume group to a logical volume:
lvextend /dev/lvm/logo /dev/md4
Is there a way to remove the physical volume /dev/md4 from /dev/lvm/logo again without harming the existing file system? I did not resize the file system yet.
I am looking for something like
lvreduce /dev/lvm/logo /dev/md4
but lvreduce only works with the -l or -L options as far I can see. So how can I ensure that only extends located on /dev/md4 are removed from /dev/lvm/logo?
This is the current situation:
Finding all volume groups
Finding volume group "lvm"
--- Volume group ---
VG Name lvm
[Code]....
