What is that supposed to mean?
I have an issue when sending snmp traps. I have an embedded system connected to a SNMP manager. I am sending traps from the box to the manager continuosly. After sometime I don't see any trpas coming out.
I get this error message.
Cannot open file /proc/net/tcp ...
: Too many open files
Cannot open file /proc/net/snmp ...
: Too many open files
What could be the reason for such an error?
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

10.5.32.202 is my management host ... is this config ok ? But it seems that trap2sink is for v2 ? How does it work ?
how can I configure snmp to receive traps from diffé²¥nt machines??
View 1 Replies View RelatedI'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?
View 3 Replies View RelatedI 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.

View 3 Replies View RelatedWe 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)?
View 4 Replies View RelatedI 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.

View 2 Replies View RelatedI 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....
I have installed Net-SNMP.It is binded to port udp 161I start it with the command: snmpd -Lo
when I do snmpget -v 1 -c public localhost system.sysObjectID.0on the same machine the snmpd is running on- I get a respond SNMPv2-MIB::sysObjectID.0 = OID: ccitt.1when I send same request from another machine (using SNMPc program) - I see no reaction.I used "wireshark" to monitor packets, and I see the requests sent from the other machine. I also see them get to the first machine.
The problem is to make sendmail use different LDA for diferent users in the same domain. For example, deliver bob@some.domain with procmail and genry@some.domain with mail.local.

View 3 Replies View RelatedI 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.
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)
I am facing issues on few machines but rest all are ok. They have the same config but I don't know what is wrong. I tried as much as I could but couldn't fix it. Here is the rpms installed on this client

The same config is working for all clients but have problems with few machines. May be I am doing something wrong in config or testing at very basic level.
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.

View 1 Replies View RelatedI 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.
