I have installed nagios in a CentOS vm and now its monitoring the local host, one remote host which is also a vm with CentOS 5.3 and one windows xp system. Is there any option for me to change the threshold time for the services given? For e.g. I had a service of current_load which comes as a default plugin while installing nagios itself. What should I do to change the threshold value of the current_load so that I might get the warning or error alert some time earlier as it was now.

I need a script to rename multiple files to the same exact name, run a program on the file then do the same for the next file. We have a unix backend system that is expecting to load the file with the filename of cards.in So I will have files named card.2009xxx, like i said i will have around 4 or five of those. I want the script to rename card.2009xxx to cards.in, run our unix program on cards.in which inturn changes the file name and once complete i want the script to rename the next cards.2009 to "cards.in"Until there are no more left in the directory and the unix program has processed all the files. All of this is occurring in the same directory. I have written some scripts but they fail by moving for example cards.200901 to cards.in then immediately moving cards.200902 to cards.in and that is not good because it is overwriting valuable data

I.e. use yy to copy a line, P or p to paste a line, and dd delete a line. Order the commands with the two lines starting with double quotes first. Then list the rest of the command in alphabetical order.
Anyone have any ideas what he's talking about? Can I copy a file and rename it at the same time while copying it to the same exact directory again? Now sure what the two lines things means either. I have an email out to him but it usually takes a long time for him to answer me. I got alot of work to do so everytime I get hung up it kills me.
In the Windows world where I came from, Irfanview freeware easily renamed a large folder of JPEG photos by EXIF time & date stamps, appending a unique number if the time and date stamps were the same. Is there an equivalent rename-by-EXIF information batch command in Ubuntu 10.04 Lucid? For example, change (based solely on EXIF information): FROM:DSC_0001.JPG TO:20110224_09:34:56am.JPG

During Slackware 13.1 setup, I chose the hostname stella-sl2. This hostname is also the one that the system is displaying before I configured network access. After configuring wired network access to my Apple Time Capsule, my hostname suddenly changed to INTERFACE='eth0'. As a result I'm noticing some very strange things, like the login prompt which has become "INTERFACE='eth0' login: ".
After configuring wireless network access to the Time Capsule, the hostname changed to "INTERFACE='wlan0'". Note that, during boot, wlan0 is brought up AFTER eth0.
Also strange is this:
bash-4.1$ cat /etc/HOSTNAME
INTERFACE='eth0'.DNSSERVERS='10.0.1.1'
bash-4.1$ /bin/hostname
INTERFACE='wlan0'
bash-4.1$
Until now, it was only a minor annoyance, it didn't prevent anything from happening, internet connection was not affected. But now I'm configuring sendmail which needs to talk to a relay SMTP server, and sendmail "HELO"'s itself using the bogus hostname:
>>> HELO INTERFACE='wlan0'
<<< 501 HELO requires valid address
554 5.0.0 Service unavailable
Probably this is caused by the Time Capsule not adhering to standards. However, the Time Capsule's firmware is the latest version, so I cannot fix this. Is there a way to prevent dhcp from changing the hostname? How can I make sure that the hostname that I configured during setup remains active?

View 5 Replies View RelatedOur Apache server is pretty much configured straight out of the box, and I've noticed it is using far more CPU and less memory than another server where I have the following:
RLimitCPU 8
RLimitMEM 100000000
RLimitNPROC 24
The Apache documentation says that if these aren't set, the values are obtain from the OS. How can you tell what those are? I'd like to see if I can tune Apache's performance, but I don't even know if these values are higher or lower than what it's currently using...

I am using the Terminal. I would like to know how do I put the current date and time on my machine and the date from a certain URL that has .php extension into a file.
After much too often wondering "hey, when did I actually start this time-consuming command?", I'm considering adding a timestamp to my bash prompt.My first try was simple: PS1="(A) $PS1" which gives a display like:(16:58) exscape ~ #
However, the problem with that approach is that it displays the time when the line was written, not when the command on it was executed. So, if I run "ls" at 16:58, and get a new prompt "(16:58) ..." and then run the next command 2 hours later, it'll look like this:(16:58) exscape ~ # new-commandI of course want the line to display the time when the command was actually run, not when the prompt appeared.

what is the directive thats required to detect a linux system? i want to to be able to detect which platform im compiling on automatically.

Sometimes it is possible to trick a Linux app by calling it like this:
HOME=/tmp/foo myapp
This would make myapp think /tmp/foo is the home directory, it won't try to get the user id, find its home directory via getpwent(). This is useful when myapp must be forced to dump some of its config files into a non-standard location different than ~.
A similar trick can be done like this: LANG=foo LC_ALL=bar myapp
This is useful when myapp needs to be called once with a different locale without having to make the change persistent by using the export bash built-in or even modify stuff in /etc/profile.
Is it possible to pull the same trick with time and date? The goal is to make an app use another time than the system ones. The final goal - to make timestamps that appear in logs/commit messages not being tied to the system time.
I am reading about jiffies in linux kernel. In one of the related example in the book Linux Device Driver, the author use
head -8 /proc/currentime
to print out some time information.
However this file is not present in my linux installation (kernel: 2.6.32-131.6.1.el6.x86_64). Why is it the case? Is it because the file path is no longer valid, or it is a distribution feature thing? It is not present in OSX too. What would be an equivalent in OSX?
