View 2 Replies View RelatedI am installing Nagios Monitoring tool in RHEL5 and I got stuck at one point. The details are as follows:
Nagios version:3.0.1
At the end of installation when I try to execute the command
#chkconfig --add nagios
Its displaying "error reading information on service nagios : no such file or directory".
Updating my install of OpenSUSE from 11.0 to 11.3 and notice that the Nagios network monitor can no longer probe servers with self signed certs.It appears to be any monitor that used openssl 1.0.0 has an issue. If I install the openssl 0.9.8 libraries and use old plugins linked against it, they work fine.

ISC DHCPd version 3.1.2
The DHCP service starts fine on boot and with manual start then works fine for about 4-5 hours. After that it just stops on its own. I start the service up and everything works fine for about 4-5 more hours untul it stops again.
What do I need to do to ensure that the service will stay uo 24x7x365?
Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
Currently I have my eth0 interface getting a DHCP address but at times the DHCP server will not be reachable. Sooo what I would like my server to do is if it cannot find a DHCP server assign a static address to eth0. Then start the DHCP service so it can then dish out some addresses.How can I do this? Surely it is possible
View 2 Replies View RelatedI have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.

Troubleshooting Nagios configuration? I'm already done with the installation and it's working fine. Now I'm working on adding Windows Server in Nagios to be monitored but the problem is my cfg_file=/etc/nagios3/objects/commands.cfg and cfg_file=/etc/nagios3/objects/windows.cfg there's no such /etc/nagios3/objects directory is existing on my nagios directory.
View 1 Replies View RelatedThis is an odd question, but I can't figure out why my nagios emails aren't being sent. In fact, I got my last one three days ago so it *should* be working.
I have everything in contacts.cfg, and the admin page tells me that the following should be sent: Unknown, Warning, Critical, Recovery, Flapping, Downtime
I also have notify-service-by-email and notify-host-by-email.
I have no idea if nagios emails just don't want to be sent or what -- and I'm not even sure if the nagios emails are even trying to be sent.
Here's my contacts.cfg code...
There's nothing in /var/log/nagios besides the mention of that email address in objects.cache, so I have no idea if an email was attempted to be sent. My sendmail queue is empty as well.
Meanwhile, I have some downtime on a service and didn't get notified. Only the web interface is helping me out here. Any ideas why I am not getting email? How can I run a test to see if everything's working okay?
When I try to log into the webgui I am getting a file to download labled "nagios". When double-clicking the file I get the error " The file /path/to/file cannot be found. Please check the location and try again".

We are using Nagios Server for different sites say India,US,Germany. All of them are in their respective groups. Now how do i create web access to 3 of them, so that they can monitor only their server? Say, India shouls be able to see and monitor only India group, US guys should able to monitor only US servers. And they not be anle to access other group.
