AIX monitoring with SNMP doesn't work

Hello,
We're trying to configure SNMPv3 on AIX to check its status through XI but we doesn't succeed.
We followed your instructions based on
https://assets.nagios.com/downloads/nag ... g-SNMP.pdf
The logging is not written on /usr/tmp/snmpdv3.log as specified on conf file, instead we got error message on /usr/tmp/snmpd.log as follow:
06/11/21 15:45:18 EXCEPTIONS: decode_SNMP_Message: pr_seq:missing mandatory parameter: module SNMP OBJECT/class=UNIV/id=1 got CONT/5 (::ffff:<IP_Nagios_Server>)
We added following lines on conf files:
VACM_VIEW defaultView system - included -
VACM_VIEW defaultView interfaces - included -
VACM_VIEW defaultView tcp - included -
VACM_VIEW defaultView icmp - included -
VACM_VIEW defaultView udp - included -
VACM_VIEW defaultView snmp - included -
VACM_VIEW defaultView 1.3.6.1.2.1.25 - included -
Since it didn't change anything we made following change (change excluded by included):
VACM_VIEW defaultView snmpModules - included -
But still not working.
Any idea on how to resolve our issue please.
Thanks & regards

Hi,
Can you please try this - I want to see where we're at with communication between the
xi server and the AIX box:
On the xi server:
cd /usr/local/nagios/libexec
./check_snmp_storage.pl -H <ip of AIX machine> -C <v3 communityname> -m "^/$" -w 2 -c 4
This check should return disk usage information from the remote AIX server, something like:
/: 11%used(1550MB/13892MB) (>4%) : CRITICAL
If it doesn't please provide the following files from the AIX machine:
/var/tmp/aixmibd.log
/var/tmp/hostmibd.log
/var/tmp/snmpdv3.log
/var/tmp/snmpmibd.log
/etc/snmpd.conf
Here is a good resource for AIX:

Thanks

Hi
On the nagios server run:
Code: Select all
nmap -sU -p 161 <ip of AIX machine>
Note: You may have to install nmap
If you get:
Code: Select all
Host is up (0.00068s latency).
PORT STATE SERVICE
161/udp closed snmp
Then you need to allow port 161 UDP on the AIX machine's firewall
Once you get:
Code: Select all
Host is up (0.00068s latency).
PORT STATE SERVICE
161/udp open|filtered snmp
then try these four commands:
Code: Select all
snmpwalk -v1 -c ABB <ip of AIX>
snmpwalk -v2c -c ABB <ip of AIX>
snmpwalk -v1 -c ABB <ip of AIX>
snmpwalk -v2c -c ABB <ip of AIX>
Thanks

Hello,
I inform you that the port is open as you can see via the following command :
Code: Select all
[root@DCPNAGIOSXIN1 ~]# nmap -sU -p 161 <ip of AIX machine>
Starting Nmap 7.70 ( https://nmap.org ) at 2021-06-15 09:30 +01
Nmap scan report for <Name AIX machine> (x.x.x.x)
Host is up (0.00065s latency).
PORT STATE SERVICE
161/udp open|filtered snmp
Nmap done: 1 IP address (1 host up) scanned in 6.01 seconds
[root@DCPNAGIOSXIN1 ~]#
And following your request here is the result of the four commands :
Code: Select all
[root@DCPNAGIOSXIN1 ~]# snmpwalk -v1 -c ABB <ip of AIX machine>
Timeout: No Response from x.x.x.x
[root@DCPNAGIOSXIN1 ~]# snmpwalk -v2c -c ABB <ip of AIX machine>1
Timeout: No Response from x.x.x.x
[root@DCPNAGIOSXIN1 ~]# snmpwalk -v1 -c ABB <ip of AIX machine>
Timeout: No Response from x.x.x.x
[root@DCPNAGIOSXIN1 ~]# snmpwalk -v2c -c ABB <ip of AIX machine>
Timeout: No Response from x.x.x.x

Try this :
snmpwalk -v1 -c public <ip of AIX>
snmpwalk -v2c -c public <ip of AIX>

Hi gsmith,
We tried both snmpwalk command and we got the same message :
Timeout: No Response from <IP_AIX>
We changed the community from public to <our_community> for both commands.
In SNMP version 2c we got the same Timeout / No Response error message
In SNMP version 1 it works
The SNMP v1 is already working as the AIX was monitoring by an old version of Nagios Core.
Since we deployed XI in replacement of the old version, we lost the AIX monitoring ability, since XI is using only SNMP version 2c or 3.
Any other suggestions ?
Thanks & regards

Hi
What does the link show?
edit /etc/snmpdv3.conf
change:
Code: Select all
COMMUNITY ABB ABB noAuthNoPriv 0.0.0.0 0.0.0.0 -
to:
Code: Select all
COMMUNITY ABB ABB noAuthNoPriv <ip of nagiosxi> 255.255.255.255 -
Code: Select all
stopsrc -s aixmibd
stopsrc -s hostmibd
stopsrc -s snmpmibd
stopsrc -s snmpd
startsrc -s aixmibd -a "-c ABB"
startsrc -s hostmibd -a "-c ABB"
startsrc -s snmpmibd -a "-c ABB"
startsrc -s snmpd
Then try the snmpwak from the nagiosxi server.
Thanks

Hello,
Please find the order result below :
Code: Select all
[root@DCPNAGIOSXIN1 ~]# cd /usr/sbin
[root@DCPNAGIOSXIN1 sbin]# ls -l snmp*
-rwxr-xr-x. 1 root root 33352 11 août 2020 snmpd
-rwxr-xr-x. 1 root root 33504 11 août 2020 snmptrapd
-rwxr-xr-x. 1 root root 177455 7 nov. 2013 snmptt
-rwxr-xr-x. 1 root root 6488 7 nov. 2013 snmptthandler
[root@DCPNAGIOSXIN1 sbin]#
We have modified the file in the AIX server, as well as the execution of the mentioned commands.
But when we launch the snmpwalk nothing happens.
Code: Select all
[root@DCPNAGIOSXIN1 ~]# snmpwalk -v 2c -c ABB x.x.x.x
Timeout: No Response from x.x.x.x
Best Regards,
