PandoraFMS not copying XML files
by Tomas Lewis 23 Apr '07

23 Apr '07

Hello. This is my first post to the fedora list, don't know if this is the correct place to post my question to, if this is not, let me know. I'm trying to set up the pandora free monitoring system in one of my servers. I have already set up the server and the web console without a problem. Besides that, I'm trying to run the pandora agent in one of the remote servers, but I have found some troubles I don't know how to solve yet. I'm running the agent in daemon mode, but when the XML is written it remains on the /opt/pandora_agent/data_out I've set up as a temporal one, it's not copied to the server /opt/pandora_server/data_in/ If I copy it manually using scp the server process the data smooth. This is my pandora_agent.conf # General Parameters # ================== server_ip 10.30.7.134 server_path /opt/pandora_server/data_in pandora_path /opt/pandora_agent/ temporal /opt/pandora_agent/data_out interval 600 debug 1 checksum 0 # Module Definition # ================= # vmstat syntax depends on linux distro and vmstat command version, please check before use it module_begin module_name cpu_user module_type generic_data module_interval 1 module_exec vmstat 1 2 | tail -1 | awk '{ print $14 }' module_max 100 module_min 0 module_descripcion User CPU Usage (%) module_end module_begin module_name cpu_sys module_type generic_data module_exec vmstat 1 2 | tail -1 | awk '{ print $15 }' module_max 100 module_min 0 module_description System CPU Usage (%) module_end module_begin module_name disk_root_free module_type generic_data module_interval 2 module_exec df -kh / | tail -1 | awk '{ print 100-$5 }' module_max 100 module_min 0 module_description Free disk Percentage of root partition module_end module_begin module_name memfree module_type generic_data module_exec cat /proc/meminfo | grep MemFree | awk '{ print $2 }' module_end module_begin module_name memused module_type generic_data module_exec cat /proc/meminfo | grep "Active" | awk '{ print $2 }' module_end Thank you all. /Tomas

libsndfile 1.0.17 unable to write file in FC6. SELinux???
by stan 23 Apr '07

23 Apr '07

Hi, I am developing an app that writes sound files. When I link it with the FC6 libsndfile libraries, either statically or dynamically, it gives me an error that it cannot open the file. It is able to create the file, because I see it there empty. When I compile the libsndfile 1.0.17 source myself, and link statically to it, the application is able to create and write the file (i.e. it works as it is supposed to). Unfortunately the debugging information has been stripped from the FC6 libraries so I can't trace the problem. The only thing I can think of is that this is some sort of SELinux issue. I am running this as a user with the default permissions (permissive if I recall). From what I have read this should mean there are no issues with SELinux at all under targeted policy. Any suggestions as to why this is happening, and possible fixes? Thanks, Stan

OT: VPS: Hosting providers? How it's done?
by Tony Nelson 23 Apr '07

23 Apr '07

We're looking for a new Virtual Private Server hosting provider. We just tried GoDaddy, but it turns out that $30/m really is too little to pay. (They use an old custom kernel, don't provide kernel modules for a firewall, won't let us upgrade the kernel, and say it is our responsibility to do so under the agreement.) I'm looking for recommendations and a bit more knowledge. Is is normal to not be able to use stock distro kernels on a VPS? (The OS is CentOS 4.4, which I presume is XEN-enabled.) What virtualization technology would normally be being used by a VPS hosting provider? Xen, UML, QEMU, VMWare, what? Am I expecting too much from a VPS when I want to upgrade the kernel? I can do it with QEMU, but that's all I know. Am I expecting too much from a VPS hosting provider when I want to set up a working firewall? -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@georgeanelson.com> ' <http://www.georgeanelson.com/>

How to run script (sleep360) without delaying bootup
by Nigel Henry 23 Apr '07

23 Apr '07

Ntpd on my FC2 install has a problem when no dialup connection is available at bootup, but does handle this well on FC6. I have a script in the ntp tarball named ntp-restart which appears to do what I want, but if I make an entry in /etc/rc.d/rc.local to run it, and as it has a "sleep 360" in the script, it justs hangs the bootup for 6 mins until the script has run to completion. Script below. #!/bin/sh # # This script can be used to kill and restart the NTP daemon. Edit the # /usr/local/bin/ntpd line to fit. # kill -INT `ps -ax | egrep "ntpd" | egrep -v "egrep" | sed 's/^$[ 0-9]*$ .*/\1'/` sleep 360 #changed from 10 /usr/local/bin/ntpd -g /usr/local/bin/ntp-wait exit 0 What I need is a way to run this script, either at, or after bootup, but automatically. This would give me enough time after bootup, and logging in, to make the Internet connection. Bear in mind that it needs to run as root, otherwise I could put something in KDE's autostart directory to run it. Ideally of course would be a script to ping an IP address out there in the big wide world, and when it gets a positive response, would run the ntp-restart script, which then could be reset to "sleep 10", as a 6 min delay would not be necessary. Any ideas folks? All suggestions, as usual, very gratefully received. Nigel.

KDE close script
by Michael D. Berger 23 Apr '07

23 Apr '07

Is there a script that runs when a KDE window closes (something like .bashrc). I would use it to kill some processes. Thanks for your help. Mike.
