Fedora Installation :: How To Clear And Reinstal MBR
Mar 23, 2009
In a dual Vista (pre-installed) - Fedora boot, I have run into a curious issue, that leads into a crash-causing memory fault when attempting to boot live CDs. After Dell technical support (inspiron 1720 laptop) confirmed (beyond doubt) that the problem is caused by the HD and not the memory chips as thought initially, they recommended reformatting the HD and re-installing everything from scratch. Since this is obviously a painful and costly (time- and data-wise) solution, I would like to see whether it might work to clear out the MBR, reinstall it from the Vista recovery CD, and then re-install GRUB somehow. Since this is an "in-principle" cure at present, I would like to seek wisdom and guidance here with respect to whether this approach makes sense and how it should be implemented.
I can't find how to clear ABRT cache (other than to forcibly 'rm -rf /var/cache/abrt/'). How does one clear out the pile (which has grown to 1.2 GB here)?
I opened firefox and it restored some ~15 windows I had open last time I rebooted. The problem is that for each window it opened it gave me a notification that it's ready, and now they won't go away. I know that I could simply remove them one by one, but that's a bit tedious and I really want to know if there's a faster way to clear all notifications when I'm not intending to look at any of them.
Here's what's happening at the bottom of my screen: I just find it really annoying because it pops up every time I accidentally touch the bottom edge of the desktop.
Compiz stopped working entirely recently and I've been trying to reinstall different version, nothing helped. Now when I look at synaptics, the version of the different package (compiz, ccsm, bcop...) are of different version (from 8.2 to 8.6). It tried reinstalling only from synaptics and it didn't change anything. I'm not sure that'll fix my problem, but for sure it doesn't help. Does anybody know what repos i should use to get a clear installation?
How do I clear the list of recent documents in Fedora 15 Gnome 3? There were a few files that I've already deleted from the system, but when I search for them, they still appear under the 'Recent Documents' list. This is proving to be a bit of a privacy nightmare.
Recently I have upgraded from Fedora 13 to Fedora 14 using preupgrade. Everything is working fine except menus on Gnome desktop. Sometimes menus are not cleared. They just hang on the desktop infinitely.
The mingetty --noclear parameter is failing with my current Fedora 13 installation. In the past this parameter would inhibit the clearing of the screen before prompting for the login name on the console. At present even with the parameter it clears the screen.
My /etc/inittab (which always worked past versions) contains:
Code:
Can someone tell me if I might be doing something wrong, or was this parameter dropped in the current version? Does anyone know of a workaround?
I understand the security purpose of the clear screen. But the particular computer is in a secured location. I prefer to look at the content of the previous screen for debugging and other chores.
I run lastb every now and again to see who is trying to p0wn my box and it dates back to november 08. how do i clear these entries to i can get a more update view? or if you know a way i can do a 'more' or something so the IP's are not flying by that would be cool too!
I just installed F9 and updated to F11 (fedora 11) and I updated the system because I couldn't get the media player working and then I installed all these packages for two days. I have tried yum clear cache and the rpm update. Here are some of the ones I tried: rm -f /var/lib/rpm/__db* yum update PackageKit ; yum clean all;
And this is the error: Error Type: <type 'exceptions.TypeError'> Error Value: 'NoneType' object is unsubscriptable File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2280, in <module> main() File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2277, in main backend.dispatcher(sys.argv[1:]) File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 600, in dispatcher self.dispatch_command(args[0], args[1:]) File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 508, in dispatch_command self.get_updates(filters) File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1743, in get_updates self._check_init() File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1965, in _check_init self.yumbase.repos.doSetup() File : /usr/lib/python2.5/site-packages/yum/repos.py, line 71, in doSetup self.ayum.plugins.run('postreposetup&apos File : /usr/lib/python2.5/site-packages/yum/plugins.py, line 178, in run func(conduitcls(self, self.base, conf, **kwargs)) File : /usr/lib/yum-plugins/rpm-warm-cache.py, line 32, in postreposetup_hook cmd = commands[0]
It seems there is a problem with Chromium with not clearing out some cache such that if you go from one site with a css file to another site with a similar named css file, the old css file remains - go to options and clear out all browser stuff and everything is okay.is there a way to automatically clear out settings when the browser is closed like the Firefox option to do this ?
Sometimes I don't want commands to be added to my history. In bash it wasCode:unset HISTFILE You would run it after a few commands and it would clear them all.I can't find out how to do it with ZSH.
l want to be linux ubuntu in my acer laptop but when l boot my computer with the cd ,it boot alright but the display is not clear you cannot see only lines .
I just started using the z shell. i have one problem, what command clears z shells history? I know how to clear the .histfile: echo "" > .histfile, but when i press the up arrow key the last command is still there.
I have a Clear 4G+ Mobile USB modem. It is a Sierra Wireless Air Card 250u. I was able to get a brief 3G connection out of the box, with Squeeze 6.0. I would be happy to at least get connection manager working, as it does in Windows XP.
Subsequent edit. I did a clean install of 6.0 Squeeze, and Clear USB modum worked right out of the box. All I had to do was, right click on Network Manager icon on upper right corner of screen, checked enable mobile broadband. clicked on edit connection info. There I manually entered Clear as my provider, checked on connect auto, and left other fields blank or default settings. I still only get 3G, but I have multiple barriers to a microwave signal in my location. But I still will continue and may need help as I configure Clears Connection Manager, and or firmware.

I am guessing I would have to locate firmware to make this device work in linux.
A friend has a website. the site has been moved to another server. I am inside of a private network.
Problem: when trying to reach his website, my browser keeps connecting to the old server which is on another continent
Windows machines have no problem with this. They connect to the new server without issues.
NOW what is hard to understand: even the PING utility is pinging the old server.
I tried these and none works: - computer restart - Clear private data in Iceweasel (has ntg to do with PING, but tried...) - installed nscd and restarted the service - modified /etc/resolv.conf to point to another nameserver than modified it back
At the same computer, if I reboot and load Windows, the browser has no problem connecting to the new server.
I am having a Oracle server installed on Linux server. I want to clear the buffers after a certain time interval. I use the following command for the same.
echo 3 > /proc/sys/vm/drop_caches
Can I have a script which will execute the above script after certain time interval OR a script which will execute the above command when certain memory size is reached.
I'm getting a weird situation where even though I updated an image in a folder for a website in apache, it's still showing the old image. And yes, I checked it in multiple browsers and on diff. computers. (Apache is in a virtualbox OS)
Here's what I've done: 1. Checked it in firefox on the host, cleared cache, reloaded 2. Restarted apache 3. Checked it in konqueror for first time, still showing old version 4. Checked it in the actual file folder and it's correct there 5. Checked it for first time on virtual machine's OS in its firefox, and it shows the wrong/old image
I'm running OS X and it appears that after SSHing to several machines, using identity files, my ssh-agent builds up a lot of identity / keys and then offers too many sometimes to a remote machines, causing them to kick me off before connecting. Received disconnect from 10.12.10.16: 2: Too many authentication failures for cwd
It's pretty obvious what's happening, and this page talks about it in more detail: SSH servers only allow you to attempt to authenticate a certain number of times. Each failed password attempt, each failed pubkey/identity that is offered, etc, take up one of these attempts. If you have a lot of SSH keys in your agent, you may find that an SSH server may kick you out before allowing you to attempt password authentication at all. If this is the case, there are a few different workarounds.
Rebooting clears the agent and then everything works OK again. I can also add this line to my .ssh/config file to force it to use password authentication: PreferredAuthentications keyboard-interactive,password Anyhow, I saw the note on the page I referenced talking about deleting keys from the agent, but I'm not sure if that applies on a mac since they appear to be cleared after reboot anyhow. So, my question is, is there a simple way to clear out all keys in the ssh-agent (the same thing that happens at reboot)?
#do some time consuming task here read -p "Give me some input: " input
Now as you might've guessed, if users press some random keys during the "time consuming task," they're read into input as well. how do I clear stdin (or at least ignore it) before I issue the read command?
