i try to monitor values with nagios over snmp from my two audiocodes SBCs (M500L).
For these i download two MIBs "AC-ALARM-MIB" + "IP-MIB_rfc4293" from https://github.com/librenms/librenms/tree/master/mibs/audiocodes rename it to .txt at the end and upload it to my ubuntu server in path /usr/share/snmp/mibs/.
Then i try to use the following command in command line.
snmpget -v3 -l authPriv -u xxxxxx -a SHA -A xxxxx -x AES -X xxxxx 123.456.789.100 AcAlarm:acActiveAlarmName
and i get the following output
AcAlarm::acActiveAlarmName = No Such Instance currently exists at this OID
I try to find out the OID from these in MIB Browser - seems like it is " .1.3.6.1.4.1.5003.11.1.1.1.1.5". When i use these OID i get same output.
Anyone has an idea?
SNMP treats all values as being entries in some database. OIDs are used to identify entries in this conceptual database. MIB files allow an SNMP manager to translate OIDs into a human-readable string, with an accompanying textual description.
The issue here is not that the MIB files are bad, or the OIDs are wrong, the problem is that, either the devices that hold this (imaginary) database do not support the entries you are trying to access, or that your user is not authorized to access those entries. A simple way to find out what OIDs are supported would be to do a full walk of the database, using something like snmpwalk <hostname> 1.3.6.1

I'm trying to add a custom mib file that contains few nodes.
For an example I tried loading SNMP-COMMUNITY-MIB as it's a standard mib and thus shouldn't throw errors.
I copied the mib into the path
~/.snmp/mibs
and also updated snmpd.conf as:
mibdirs +$HOME/.snmp/mibs
mibs +SNMP-COMMUNITY-MIB
I tried to print the oid of one of the nodes "snmpCommunityName" using:
snmptranslate -m +SNMP-COMMUNITY-MIB -IR -On snmpCommunityName
it worked fine and the oid was printed.
I then tried to list all using snmpwalk:
snmpwalk -v2c -c public localhost
But the nodes from my mib and its oid's were not printed.
How can I have my oids listed on snmpwalk?
I accidentally noticed that when I run snmpwalk without an OID, I get only 593 variables from my device, and the device-specific variables are missing. But if I add 1 as the OID, I get 2527 variables, including the ones which are the most useful. So in your case try adding 1 at the end of the snmpwalk command:
snmpwalk -v2c -c public localhost 1
Edit: The above method worked on an APC PDU, and on a Supermicro BMC. The BMC was a bit confusing because it did not use the OID names from the MIB file, but all the information I need is there.
I'm trying to make a request to a function in a SAP RFC server hosted at 10.123.231.123 with user myuser, password mypass, sysnr 00, client 076, language E. The name of the function is My_Function_Nm with params: string Alternative, string Date, string Name.
I use the command line:
/usr/sap/nwrfcsdk/bin/startrfc -h 10.123.231.123 -s 00 -u myuser -p mypass -c 076 -l en -F My_Function_Nm
But it always shows me the help instructions.
I guess I'm not specifying the -E pathname=edifile, and it's because i don't know how to create a EDI File to include the parameters values to the specified function. Maybe someone can help me on how to create this file and how to correctly invoke startrfc to consume from this function?
Thanks in advance.
If you actually check the help text the problem shows, you should find the following passages:
RFC connection options:
[...]
-2 SNA mode on.
You must set this if you want to connect to R/2.
[...]
-3 R/3 mode on.
You must set this if you want to connect to R/3.
Apparently you forgot to specify -3...
You should use sapnwrfc.ini which will store your connection parameters, and it should be places in the same directory as client program.
Sample file for your app should be following:
DEST=TST1
ASHOST=10.123.231.123
USER=myuser
PASSWD=mypass
SYSNR=076
RFC_TRACE=0
Documentation on using this file is here.
For calling the function you must create Bash-script, but better to use Python script.
I am using UFTP to transfer files within the subnetwork computers.
But when I used -H to send only particular computers instead of sending to all computers, it is not working as expected.
Let me explain in detail :
I have two windows machines in same network of IP's 172.21.170.198,172.21.181.216 respectively.
From one of the system, I used below mentioned command to send the file
uftp.exe -R 100000 -H 172.21.170.198,172.21.181.216 e:\setup.exe
But both machines won't receive those file.
But if I use this command both machines will receive the file.
uftp.exe -R 100000 E:\setup.exe
I want to know whether I made any mistake.
Please correct me if I am wrong.
Thanks in Advance.
Kindly revert back for any clarifications.
Regards,
Thiyagu
If ipv6 isn't enabled, it would look like this, converting the ipv4 addresses to hex (with a converter like http://www.kloth.net/services/iplocate.php):
uftp.exe -R 100000 -H 0xAC15AAC6,0xAC15B5D8 e:\setup.exe
But if you have an ipv6 address on the client, the client id sort of comes from the end of it backwards. Like if the address was "fe80::e5ca:e3ca:fea3:153f%5", the command would look like:
uftp.exe -R 100000 -H 0x3f15a3fe e:\setup.exe
(coming from "fe a3 15 3f")

Server starts successfully.
I am running command: snmpwalk -c public -v 2c 127.0.0.1:1610
It gives
Error in packet.
Reason: authorizationError (access denied to that object)
File: /home/sshekhar/.snmp/mibs/snmp.acl has 700 access set to it.
I am new to SNMP and all I am looking forward is to configure JBoss 6.4 to use SNMP for monitoring.
Also, there is no data written in file: /home/sshekhar/.snmp/mibs/snmp.acl
Also, I created a user using
net-snmp-create-v3-user -ro -A password -X password -a MD5 -x DES myUser
Now, when I am trying to run the command snmpwalk -c public -v3 -u myUser -a MD5 -x DES -X password -A password localhost:1610
it gives me error saying snmpwalk: Unknown user name
snmpwalk -v1 -c public localhost:1610 gives no result
snmpwalk -v1 -c groupv3 localhost:1610 gives End of MIB
Can anyone please help me in understanding what might be the error and what should be my next steps to debug/resolve the issue?
I'm afraid I don't have an exact answer for you, but I can give you a little context about the SNMP versions-
SNMPv1 and SNMPv2c only use community string for authentication
An example SNMPv1 walk is as follows (community string is "public):
snmpwalk -v1 -c public 192.168.1.1
And an example SNMPv2c walk:
snmpwalk -v2c -c public 192.168.1.1
SNMPv3 has quite configurable authentication, using up to:
Security name (aka username)
Security level (noAuthNoPriv, authNoPriv, noAuthPriv, authPriv)
Auth protocol (e.g. SHA, AES)
Auth key (string)
Privacy protocol (e.g. MD5, DES)
Privacy key (string)
(optional) Context name
(optional Engine ID
As you can see, it can be quite complex- the "security level" is a setting that sometimes needs to be specified, it defines how much of the SNMPv3 security model you're using- if you're using an auth protocol and key and a privacy protocol and key, you'll need to use authPriv; if you're using none of those, you'll need to use noAuthNoPriv (just the security name).
An example SNMPv3 walk is as follows:
snmpwalk -v3 -u some_username -a SHA -A 'some_auth_key' -l authPriv -x AES -X 'some_privacy_key' 192.168.1.1
Basically, I'd recommend trying to setup SNMPv1 or SNMPv2c until you can get everything working nicely- I can't speak for JBoss, but on most networking devices this is simply a matter of picking an SNMP version (e.g. v2c) and specifying the read only community string (e.g. "public").
When/if you get to configuring SNMPv3, you might just have to be flexible with some of the different settings I find (again, in the context of network devices) that you won't find one setting that'll work on lots of different vendors of devices, you'll have to try some different auth protocols, different privacy protocols etc.
Best of luck!
I am rebuilding an Icinga server that has been left behind by a previous employee. I have everything up and running, except for a bunch of MIB files for 3com switches that I cannot get to work.
The server is a CentOS 6 OpenVZ container.
In the original server there is a bunch of mib files in the default location at /usr/share/snmp/mibs/ and the 3com ones at /usr/share/snmp/mibs/3Com_4500/MIBs. The 3Com mibs work fine:
/usr/lib/nagios/plugins/check_snmp -H 10.10.111.11 -P 2c -C public -o hwDevMFanStatus.65536 -s "active(1)" -m A3COM-HUAWEI-LswDEVM-MIBSNMP OK - active(1) |
In the new server, the MIBs in the 3com folder do not get acknowledged and I get errors like the following:
/usr/lib/nagios/plugins/check_snmp -H 10.10.111.11 -P2c -C someuser -o hwDevMFanStatus.65536 -s "active(1)" -m A3COM-HUAWEI-LswDEVM-MIB
External command error: No log handling enabled - turning on stderr logging
Cannot find module (A3COM-HUAWEI-LswDEVM-MIB): At line 0 in (none)
hwDevMFanStatus.65536: Unknown Object Identifier (Sub-id not found: (top) -> hwDevMFanStatus)
/etc/snmp/snmpd.conf is identical for both servers and so is /etc/sysconfig/snmp.
set does not show any ENV variable related to snmp or mib.
Thanks
You are confusing snmpd.conf and snmp.conf the former being the configuration file for the SNMP daemon whereas Net-SNMP applications use snmp.conf.
The mibs/mibdirs directives you are interested in would be specified in snmp.conf (see also man snmp.conf.
