I am running Nagios on CentOS. Everything is working fine, all my clients status is ok. One thing which is confusing me is "Root Partition WARNING" on my own server which has Nagios installed. I think that these things are controlled by nrpe, which is installed in clients servers. what i want to know is how i manage my own server, in which config files i have to make changes?

I've installed BOINC for first time (from suse repos). I'm worried about running BOINC as root. How can this be avoided? I'd first like to exhaust all options with the official opensuse repo version of BOINC. If I am unsuccessful, then I'll try the version from Berkeley website.

I have Centos 5.3 on our server When I log-in in webmin I have a message "Warning - Your system is actually running CentOS Linux version 5.3." In the next line I have a button "Update Detected Operating System" My question is Do I need to click the link and update Detected operating system? If I do, is it going to change any configuration on our server?

View 1 Replies View RelatedI installed Nagios on my Ubuntu 10.04 server using apt-get and when I accessed the web console, everything was OK. I made some changes to apache (creating some new virtual sites) and since then Nagios gives me a warning message for HTTP with the message, HTTP WARNING: HTTP/1.1 404 Not Found. The sites that I created are working perfectly. I noticed that the attemps are 4/4. Does this need to be reset or does Nagios automatically reset that once it detects the issue is resolved?
View 1 Replies View RelatedWith the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages
I also tried to use Gparted but I couldn't install it :(
My root partition is completely full and I want to extend it.

I have just configure RAID 1 on my IBM X3400 Server in CENTOS 5 ..Partition information is md0 boot , md1 swap and md2 is root ....but after resyn when i run cat /proc/mdstat I realize that md0 and md1 is ok and present with [UU] status. BUT the md2 is showing on one [U_].. that means my root partition is not properly in RAID 1.. how can i make it active in both drive. Or i need to reinstall complete system again.

I would like to install Nagios on a server without having access to root. I plan to install Apache without root in a local space to run the nagios web application. As far as the nagios plugins I plan to use NRPE and I do not need the two plugins require root to run so I am fine with that.So I have seen hints on how to install the plugins and apache without root but I have seen nothing on installing nagios itself. The odd thing is that the machines I will install on already have a nagios and nagioscmd users/groups so I a plan at this point to use them. According to the instructions it seems like all I need root for now is the 'make install'.So what does make install do that requires root and is there a way I can get around it

I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

View 1 Replies View RelatedI've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

I have been playing around with shell scripting, nothing too complex just learning the basics. if i try to run a script as root (by entering "sudo" then the "command") it says command not found. i can only do it ass root if i specify the full path (/home/username/bin/command) im pretty sure the directory that my scripts are in are part of the superusers path.
