Networking :: Nagios Not Receiving SNMP Data?

May 18, 2010

I have recently set up nagios on a ubuntu server (9.10), and set it up to monitor all the servers, switches etc, following the quickstart guide provided on the nagios website.My problem is this:I have setup the nagios-plugins, and tried to set it up to monitor the network switches via SNMP but receive the following within the nagios web interface:SNMP problem - No data received from host I tried it from the command line, and got the exact same error.Is there some further configuration I need to do to be able to get this data?I've used up all my google-fu, and read over everyone else's problems on every forum I could find, but to no avail.

Software :: Receiving UDP Multicast - Blocks As If There Is No Data

Nov 6, 2010

I am trying to port some MS Visual Studio C++ code to Linux/wxWidgets. The code is socket-based and very similar between Windows and Linux. In Linux the socket, bind, and setsocketopt all return with no error. See:

BOOL CAV15Input::SetupSocket(BOOL Out)
{ if(pU->PrDebug) {
sprintf(_send,"CAV15Input::SetupSocket for port %d",pSonar->dPort);
pU->OutMsg(_send,1,0); } pSonar->UDP_Sock=0; pSonar->UDPError=0;
if(pSonar->UDP_Sock<0 ) {
pU->OutMsg("socket failed on SetupSocket",11,0);
return FALSE; }
// the AF_INET address family, which contains IP addresses,
// from Dave Goffe:
//> int t = 1;
int t=1; if(setsockopt(pSonar->UDP_Sock,
(char *)&t,sizeof(t)) <0) {
pU->OutMsg("set SO_REUSEADDR failed in SetupSocket",11,0);
return FALSE; }
if(bind(pSonar->UDP_Sock,(sockaddr *)&local,sizeof(local)))
{ CloseSock();
pU->OutMsg("bind failed in SetupSocket",11,0);
pSonar->UDPError|=8; return FALSE; }
if(pU->PrDebug) {
sprintf(_send,"socket setup & bind OK for port %d",pSonar->dPort);
pU->OutMsg(_send,1,0); }
// Join multicast group
if(pSonar->datatype) // for element data
else // for beam data
(char *)&mreq,sizeof(mreq)) <0) {
pU->OutMsg("join multicast failed in SetupSocket",11,0);
return FALSE;
} if(pU->PrDebug) {
if(pSonar->datatype) // for element data
sprintf(_send,"join multicast OK on %s",pSonar->IP_Add_ELD);
else // for beam data
sprintf(_send,"join multicast OK on %s",pSonar->IP_Add_HRB);
pU->OutMsg(_send,1,0); }
jMCast=1; return TRUE; }

But then when I try
it blocks as if there is no data. (In Windows this works fine.) Is there something else in Linux and/or wxWidgets that I'm missing that could prevent UDP datagrams from being received? Is there some way in Linux to monitor incoming UDP traffic?

I would like to send a data using one thread and receive a data using other thread by using a same socket connection using USD sockets. The calls i am using for sending and receiving are send(), recv(). let me know is it possible to send and receive the data parallel (Full duplex communication)?

General :: Change Size Of Network Data Receiving Buffer On OS?

Jan 21, 2010

We know that, in a network, data transfer time is dependent on capacity of the receiving node. I have two Linux systems A (sender) and B (receiver) connected. I want to simulate congetion in a network, that means I want to increse the time taken to transfer some data. I believe, I can do this if I can reduce the capacity of the receiver node B. That perhaps possible by decreasing the receiving buffer size of B. How can I change the receiving buffer size of this linux system B?

Programming :: Receiving Wrong Data On Winsock From Unix Socket

Jan 28, 2011

currently I've got a big problem on programming with sockets. I use the winsock2 API and want to receive data from a multicast adress running on a UNIX-PC. The connection works fine and I really receive data from this group, but as it seems not the right packages. The received data is saved in a char[]. E.g. at received_msg[12] is a float value. This one I would like to read out, convert and use it in later progress the next value is y at received_msg[16]. The same Code works on a Unix PC with unix sockets but converted to winsock I've got the described problem and I have to make this code work under windows.

Here a piece of the code (received_msg[12]='3f'):

Buffer is a struct containing the two float values x and y. If I convert the char as this under windows the value of x is a huge number. The correct value is around 192, so receveid_message[12] should be 1.92. Could it be that the Unix-PC is sending data in an other way than the winsock receive it?

Programming :: Detect A Closed Tcp Client Connection When Client Is Only Receiving Data ?

Mar 9, 2011

I am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.

Ubuntu / Apple :: Fresh Installation - Receiving Sync Error?

Feb 17, 2010

I'm trying to run Mac OSX Leopard + Ubuntu on my Macbook White 4,1. I've read multiple user guides, but for some reason it screwed up when I hit the partition button on rEFit. I received the 'gpsync' (sp?) error. I couldn't delete any of my partitions or make them go back to normal... As we speak I'm wiping my hard drive. I would really LOVE to start over FRESH. With Mac OSX, then to install Ubuntu. How can I go about installing Ubuntu on my Macbook without getting the sync error, and screwing up my partitions. Yes I read the user guide, and yes.. I did it step by step and still received the errors. I would love to fool around on Ubuntu, but the errors were stopping me.

General :: Check_NRPE From Ubuntu Server To OpenWRT Router - Connection Refused By Host

May 23, 2011

I am trying to monitorize an OpenWRT (Backfire 10.03, r23115) router from an Ubuntu server, but I am having some problems. I have installed Nrpe (2.12) on the remote host (OpenWRT), I have executed the program as a deamon (/usr/sbin/nrpe -d) but when I start the NRPE deamon, I don't get anything about NRPE executing netstat -at or ps -ef.I would need to install check_nrpe on OpenWRT to find out if NRPE is working, but I can't find any ipk package with it. Now, once in the monitoring host when I try to reach the remote host from the server:

/usr/local/nagios/libexec/check_nrpe -H ip_remote_host

I get: Connection refused by host

Even, trying with localhost:

/usr/local/nagios/libexec/check_nrpe -H localhost

I get the same error: Connection refused by host

I have installed Nagios Plugins and the check_nrpe plugin. I have edited the /etc/nrpe.cfg file:

allowed_hosts= ip_server

I don't exactly know if it is remote host's fault, monitoring host's fault or both.

Software :: Timeout Error Occurred Trying To Start MySQL Daemon ?

Sep 22, 2010

for some reason, which I have exhausted all my thoughts upon..

I have mysql 5.0.77

I just made an amendment to the auto_increment_increment variable.. from 10 to 1

Gone to restart mysqld (im on redhat FYI) and get the error:

'Timeout error occurred trying to start MySQL Daemon.'

It fails to stop, and obviously fails to start.

I have included below my 'my.cnf' file but I cant see any issues with it, and can't for the life of me think why there is something wrong.

If I ever come across an issue, I don't tend to ask but instead try and figure it out (usually with success) but this time.. I just cannot get my head around it..
