The communication between nagios and nrpe agent in the monitored host, can be without SSL? The problem is that I have 2 different versions of debian running on the machines and there are problems related to the libssl-dev package!
View 11 RepliesI've followed all the instructions in nagios documentation to install the nrpe agent in a remote host, but the daemon nrpe is not listening on port.. that means I can't even test it localhost!
netstat -at | grep nrpe
returns nothing.
You added the nrpe entry to your /etc/services file - done
The only_from directive in the /etc/xinetd.d/nrpe file contains an entry for "127.0.0.1" - done
xinetd is installed and started - done
Check the system log files for references about xinetd or nrpe and fix any problems that are reported - syslog empty..
Installed lsof and lsof +M -i4:
xinetd 25680 root 5u IPv4 75987 TCP *:nrpe (LISTEN)
Is there anything else I can do to correct this? I configured this yesterday and it was working ok.. but today when got into computer it stopped working
I want to have like 4 machines, each one of them with Nagios and nrpe (plugin+daemon) installed so that every one of the machines could be able to monitor all of the others.. Is there any problem doing this? Or having nrpe+nagios in the same machine is ok?

CHECK_NRPE: Error - Could not complete SSL handshake.
We have Nagios running on a server, and are installing NRPE as a daemon on web servers we need to monitor. I'm two servers in and have hit a small snag. The two servers we're currently trying to monitor are, to the best of our knowledge, very similar (Centos 5.4, Apache, MySQL, PHP etc etc), and the installations of NRPE on them should be the same. One is being monitored just fine, however we can't check on the other one without including the -n switch (to disable SSL) in the check_nrpe call. If we don't, however, the error we get is, "CHECK_NRPE: Socket timeout after 10 seconds.". In /var/log/messages on the machine that fails we see:
May 24 17:23:49 ourserver xinetd[23583]: START: nrpe pid=27932 from=123.123.123.123
May 24 17:23:59 ourserver nrpe[27932]: Could not read request from client, bailing out...
May 24 17:23:59 ourserver xinetd[23583]: EXIT: nrpe status=0 pid=27932 duration=10(sec)
The only kind of related thing I can think of that's different between the two machines is that one (the one that works) has actually had an SSL certificate installed on it, for the site it hosts.
I want to monitor RDS (mysql database of EC2) using Nagios. In command line ( I am able to do it but I dont know how to feed it in nagios . On nagios server if I execute the following command , I am able to fetch the information of database (RDS)
Nagios_server #/usr/local/nagios/libexec/check_mysqld.pl -p<password> -f -u <username> -A uptime,threads_connected,slow_queries,open_tables -H <hostname> -q 'SHOW STATUS'
output :- MYSQL 5.1.50 OK | uptime=344783 threads_connected=672 slow_queries=0 open_tables=64
Note :- Here the host name is public dns name (x.y.z.amazon.com) .We cant ping to this host.With mysql command , we can log in and work on databases.
I have been running a webserver for a time now. And for fun I thought I would use Nagios for monitoring it. But the installation instruction says install this on webserver01 and that on webserver02. I only have one server and want to monitor it remotely from a simple browser. Is this possible or does Nagios need at least two separate servers? Can't it just run it on my one server?

The Server in the above diagram can be accessed by Client3 and Client4 but not at all by Client1 or Client2. Router0 specifies the Server as a DMZ Host. I would be more specific but this is not my server. I don't use a DMZ, I forward ports when they are needed. In this case I represent ISP1 and the server belongs to a befuddled client. Client1 & Client2 can send packets to each other, no problem. Could the DMZ be breaking communication between the Server and Clients 1 & 2?
i am using NCTUns simulator and having problem while receiving message from an OBU. sending a message works properly but recving creates problem and fails. i am using exactly the same function as used by the developers in the demos but still no luck. i copy the code attch the screen shots to have a look
sendto() and recvfrom() are used for message transfer. they both return >-1 if they are executed successfully. please have a look in the screenshots. agentClientReportStatus is the built in packet format which im using here whose fields i filled manually are in the code below.
agentClientReportStatus *message,*mssg;

Why doesn't encrypted WLAN communication work for me? I've got an HP Probook 6555b with Ubuntu 11.04 32-bit. When I set my WLAN router to unencrypted I'm able to connect. But if I choose WPA-PSK-TKIP or WPA2-AES or WPA-PSK & WPA2-PSK I can't connect. Ubuntu prompts me to enter my encryption key. I enter it. It runs for a while and then prompts me again. The little icon at the top right of the screen next to the speaker symbol is where I can see it trying to connect.

View 2 Replies View RelatedI have installed 10.04 on several machines as well as imbedded inside VISTA. All of these installs work fine except the one on my HP Pavillion dv9000. The synaptics device on these machines is very touchy in all operating systems, but caused a strange issue in ubuntu 10.10. While connected to the internet and working fine I barely touched the pad and everything quit. I rebooted and found no way to reconnect to the internet. On the panel there was a little icon about the connection manager. Hovering over this icon gave the message "Connection Manager daemon not working". The usual tab to "enable networking" was dim and could not be activated.
I searched for several hours and found no reference regarding this daemon. Is there a source of the op sys names for such daemons and what sort of terminal command would I use to restart it if I knew what it was called? I ended up scrubbing the partition and reinstalling. Even the recovery process would not get the daemon to restart.
