General :: Send Snmp Traps Based On Syslog Messages?

Oct 24, 2010

I need to be able to send snmp traps based on certain severity or content of syslog messages. Can this be done from standard linux? Alternatively, are there MIB's out there that support syslog events so I can get the status from snmp?

What is that supposed to mean?

Networking :: Sending SNMP Traps FROM A Workstation?

Apr 28, 2011

I have created this thread as it sis realy hard for me to send traps from my Linux workstation... I m lost with v1/v2/v3 snmp... So here is the initial configuration: (without traps)

rocommunity myrocom
rwcommunity MyL33tP4ss 10.5.32.202
rwcommunity MyL33tP4ss 127.0.0.1
syslocation "FR"
syscontact root

From there i can "poll" my system. But what should i do if i want my Linux system sending traps when disks are full or system overloaded etc...I have found information on Internet but not easily understandable It is for v3:

rwuser admin
createUser admin MD5 mypasword
#
# From there i would have to comment the lines regarding the communities
#

[code]....

10.5.32.202 is my management host ... is this config ok ? But it seems that trap2sink is for v2 ? How does it work ?

Networking :: Selecting / Modifying SNMP Traps On Switches

Dec 20, 2009

I'm curious as to what defines the SNMP trap info sent by switches? I would like to get updates on 802.1x authentication and state of switches (all manufacturers if possible). Is the data sent via traps determined by the manufacturer or is it possible to modify/select it from the switch MIB?

OpenSUSE :: How To Snmp Traps Work

Nov 27, 2010

I have a favor to ask, I've been having a really hard time trying to understand how snmp traps work, what can they do for you, and why they are useful. I've done some research and I've even set up snmp clients on linux systems, not necessarily the traps. I know they communicate on port 161 and 162 and I also know that you set them up to connect to a community string. Still I cant grasp the concept. If you don't mind can any one break it down for me, in very basic terms.

Server :: Sending SNMP Traps (Info On CPU / Memory Usage)

Dec 13, 2010

We have a situation where we have to set up a server to send traps with information regarding CPU, memory usage, etc. I know snmpd can be set up to allow another process to request snmp information about the server, but can it be done the other way around (have a host send information about itself to another server through snmp)?

Server :: Send Up/down Traps From Router To Snmptrapd?

Apr 8, 2011

I just installed FC14 64 bit system and I am looking to setup a snmp trap server so I can send up/down traps from my router to it which in turn will email me though sendmail. I have installed "net-snmp-utils-5.5-21.fc14.x86_64" and "net-snmp-libs-5.5-21.fc14.x86_64" packages and have downloaded snmptt_1.3 but I don't have the command "snmptrapd". Is there another package I need for this? Could it just be x64 doesn't support it?

Here is some info off the box.

[root@scanserver ~]# uname -a
Linux scanserver 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Networking :: Gateway Assignment And Use Of DHCP Relay Agents + DHRELAY

Jun 22, 2010

I am having some difficulties comprehending some networking concepts relating to multiple subnets and dhcp servers, or dhcp relay servers. I have built home networks many times before, and they have all followed a very simple formula. A single subnet, let's say 192.168.1.0 which is fairly typical for me. My network's DNS server is always also my networks DHCP server. Typically at 192.168.1.1. When a DHCP client broadcasts for an IP over the subnet, 192.168.1.1(My DNS/DHCP server) will not only tell the client what it's new IP is to be, but will also tell the client what it's Gateway server is. This is ALSO 192.168.1.1 for me typically.

In this manner, a client broadcasts for networking information and is given a usable IP, and told to use 192.168.1.1 for most other functionality. Very simple. However, I am uncertain how to expand this to other subnets. Say.. 192.168.2.0.

A: I can use a separate DHCP server for each subnet. or B: I can use a DHCP Relay agent for 192.168.2.0 to pass the DHCP requests to the primary DHCP server on the 192.168.1.0 subnet.

Option A: is fairly straight forward and have had it functioning fine, but it is really B: I want to know more about. It seems somehow much cleaner to me. I prefer to centralize as much of my network provisioning services as possible. It makes it easier to manage TYPICALLY. My question though is related to Gateways and the use of DHCP Relay Agents....

Networking :: SNMP Only Updating Every 12 Seconds?

Sep 14, 2010

I have enabled SNMP monitoring in my debian box (using apt-get install snmp) and configured it to allow my PC to query the server.

I'm able to query the server and get SNMP data but when I get STG to give me a per/second graph of the interface octets, it only updates the data every 12 seconds or so.

Is this a setting in SNMP which could be causing this problem? If so, how can I enable it so that SNMP can give me up to the second octet rates.

Networking :: SNMP - Snmpwalk Not Working 100%

Mar 14, 2011

2 machines (one of them working as a server to monitor the network with IP 192.168.100.110 and the other one to be monitored with IP address 192.168.100.1):

In the first machine:

snmpwalk -v1 localhost -c public sysName (working fine)
snmpwalk -v1 192.168.100.1 -c public sysName (don't works -> Timeout: No Response from 192.168.100.1)

In the monitored machine:

snmpwalk -v1 192.168.100.110 -c public sysName (it works)
snmpwalk -v1 localhost -c public sysName (dont works -> Timeout: No Response from localhost)

CentOS 5 Networking :: UCD-SNMP-MIB Doesn't Seem To Work

Aug 20, 2009

I am trying to monitor a Centos 5.3 box using SNMP and I am having a lot of trouble getting the data that i need from it. Everytime I try to get information from the UCD-SNMP MIB it returns "End of MIB". It is my understanding that UCD-SNMP is a standard package when Net-SNMP is installed and should always be there. Then why can't I access it? I have tried removing the reinstalling Net-SNMP, but that hasn't worked. My server is update date on all it's patches as well. It is quite old hardware, but I don't believe that should affect SNMP from being gathered. Iptables is down, and I cant' even get it from the local machine.
