snmp Timeout No Response from

[cirox]

Hi,

i read a lot of docs but i cant get it working. I have setup cacti on a etch box working well with localhost graph. php.info shows:

Code: Select all

NET-SNMP Support 	enabled
NET-SNMP Version 	5.2.3

Now i want to monitor other boxes. So i had to install net:snmp right?
ok, after i spent a lot of time to find the right packages i installed the packages in this way:

i installed an the remote host, i want to monitor and on the local box with cacti

Code: Select all

libsnmp9
libsnmp9-dev
libsnmp-base
snmp
snmpd

so i got the snmtpd.conf an remote host and local box as well

then i read the cacti snmpd how-to again but now i am really confused. I start with minimalistic conf (cause i want to understand it)

Code: Select all

rocommunity public

i restarted the snmpd daemon and this is working

Code: Select all

snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux srvx.xxx.tld 2.6.18-4-686-bigmem #1 SMP Thu May 10 00:23:00 UTC 2007 i686

ok, but now i want to monitor via snmp from my cacti box to this remote host but an cacti box i get:

Code: Select all

snmpwalk -v1 -c public 78.47.xxx.xxx 1.3.6.1.4.1.9.2.1
Timeout: No Response from 78.47.xxx.xxx

there is no firewall an i started tcpdump on box, i want to monitor:

Code: Select all

srvx:~# tcpdump -ieth0 -n port snmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
11:47:27.321121 IP 217.20.xx.xx.4302 > 78.47.xx.xx.161:  GetNextRequest(25)  .1.3.6.1.2.1
11:47:28.324448 IP 217.20.xx.xx.4302 > 78.47.xx.xx.161:  GetNextRequest(25)  .1.3.6.1.2.1

so i think before getting cacti to work i should get this working:

Whats is wrong?

No. net-snmp in this context refers to an optional module for php. The target systems will require sth like a net-snmp rpm. Version 5.4.1 is current.

You surely configured snmpd.conf on the remote machine?

Code: Select all

snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux srvx.xxx.tld 2.6.18-4-686-bigmem #1 SMP Thu May 10 00:23:00 UTC 2007 i686

Well, this enables you to SNMP query localhost. This is surely useful. But you will have to apply the configuration procedure to each of your targets
