Hightower Posted February 24, 2010 Posted February 24, 2010 I'm in the process of playing with Nagios. So I've installed the NSClient++ app onto a test server and opened the 12489 port in the local firewall. I've followed the instructions set out in the docs, but I get an error could not fetch information from server. Anyone got any ideas for this? I've used Google but not much look finding anything helpful.
pete Posted February 24, 2010 Posted February 24, 2010 Is the service running? The nsclient installer doesn't always manage to start the service (on some 2008 boxes). If you run the plugin manually, does it give the same error - i.e pete@server:/usr/local/nagios/libexec$ ./check_nt -H IPADDRESS -p 12489 -v UPTIME Should return system uptime. Also look at NSC.ini in the nsclient++ program dir and check the allowed_hosts=NAGIOSIPADDRESS line is correct.

I've tried running that code above (and others) from CLI on nagios box and produces the same error I see in the web GUI. Also ensured the password is blank and hosts is blank (which allows everyone access) - but also tried it with a password and with the IP address of the nagios machine.
pete Posted February 24, 2010 Posted February 24, 2010 Anything useful in the nsclient log on the machine?

pete Posted February 24, 2010 Posted February 24, 2010 (edited) Couple of things. 1) You're not on the latest version - 0.3.7 is current. Downloads - NSClient++ - Trac. You're missing a few bugfixes. 2) These lines are of interest: 2010-02-24 13:01:44: error:CACHEd:\documents\Visual Studio 2005\Projects\NSCP\branches\stable\include\Socket.h:645: bind failed: 10048: Only one usage of each socket address (protocol/network address/port) is normally permitted. 2010-02-24 13:01:44: error:d:\documents\Visual Studio 2005\Projects\NSCP\branches\stable\include\Socket.h:668: Socket did not start properly, we will now do nothing... 2010-02-24 13:01:44: error:d:\documents\Visual Studio 2005\Projects\NSCP\branches\stable\include\Socket.h:645: bind failed: 10048: Only one usage of each socket address (protocol/network address/port) is normally permitted. 2010-02-24 13:03:03: debug:CACHEd:\documents\Visual Studio 2005\Projects\NSCP\branches\stable\include\Socket.h:637: Bound to: 0.0.0.0:5666 And that log does seem rather chatty compared to what I'd normally expect. If you telnet to 12489 from the Nagios box (or use nmap -p 12489 nsclientIPAddress) does the port show as open? Edited February 24, 2010 by pete
Hightower Posted February 25, 2010 Author Posted February 25, 2010 If you telnet to 12489 from the Nagios box (or use nmap -p 12489 nsclientIPAddress) does the port show as open? PORT STATE SERVICE 12489/tcp open unknown Nmap done: 1 IP address (1 host up) scanned in.... Downloading latest version to try that now. Will post back soon!
Hightower Posted February 25, 2010 Author Posted February 25, 2010 Don't want to speak to soon but seems the latest version of NSClient has got it working. Will post back soon when definate!
Hightower Posted February 25, 2010 Author Posted February 25, 2010 Yep - that newer version has got it going! Just got to spend a little time doing the rest of the servers, and working out what services I need to monitor. Having trouble getting it to monitor a HP ProCurve switch too. The ping returns ok but it can't get the uptime through snmp: External command error: Timeout: No Response from IPADDRESS:161.
pete Posted February 25, 2010 Posted February 25, 2010 Yep - that newer version has got it going!

The ping returns ok but it can't get the uptime through snmp: External command error: Timeout: No Response from IPADDRESS:161. Assuming the community is set correctly on the switch, it has snmp turned on, the switch and nagios are expecting the same version of snmp and the nagios box is allowed snmp access (iirc you can filter access on HP switches). Does snmpwalk send anything useful back? pete@server:~$ snmpwalk -v 1 -c public SWITCHIP (-v = snmp version, -c = community name) Should dump a few screens of info similar to SNMPv2-MIB::sysDescr.0 = STRING: ProCurve J9088A Switch 2610-48, revision R.11.22, ROM R.10.06 (/sw/code/build/nemo(ndx)) SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.11.2.3.7.11.77 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (58377345) 6 days, 18:09:33.45 SNMPv2-MIB::sysContact.0 = STRING: Redacted SNMPv2-MIB::sysName.0 = STRING: Room 25 Procurve 2610-48G SNMPv2-MIB::sysLocation.0 = STRING: Room 25 SNMPv2-MIB::sysServices.0 = INTEGER: 74 IF-MIB::ifNumber.0 = INTEGER: 55 IF-MIB::ifIndex.1 = INTEGER: 1 IF-MIB::ifIndex.2 = INTEGER: 2 IF-MIB::ifIndex.3 = INTEGER: 3 IF-MIB::ifIndex.4 = INTEGER: 4 IF-MIB::ifIndex.5 = INTEGER: 5 IF-MIB::ifIndex.6 = INTEGER: 6 IF-MIB::ifIndex.7 = INTEGER: 7 IF-MIB::ifIndex.8 = INTEGER: 8 IF-MIB::ifIndex.9 = INTEGER: 9 IF-MIB::ifIndex.10 = INTEGER: 10 IF-MIB::ifIndex.11 = INTEGER: 11 IF-MIB::ifIndex.12 = INTEGER: 12 IF-MIB::ifIndex.13 = INTEGER: 13 IF-MIB::ifIndex.14 = INTEGER: 14 snipped for brevity
Hightower Posted February 25, 2010 Author Posted February 25, 2010 I've tried an snmpwalk of all versions (1, 2c, 3) and each one returns Timeout: No response from IPADDRESS. As far as I can tell SNMP is enabled, but the only config settings I can find on switch (even when telnetting in) is for the community strings. That said, the public community string is already set with read access.
pete Posted February 25, 2010 Posted February 25, 2010 I've just had a look on a Procurve 2610 here and I can't see anything special about our config. Startup configuration: ; J9088A Configuration Editor; Created on release #R.11.22 hostname "Room 25 Procurve 2610-48G" snmp-server contact "Redacted" snmp-server location "Room 25" no telnet-server trunk 49-50 Trk1 Trunk ip default-gateway gatewayIP sntp server dcIP timesync sntp sntp unicast snmp-server community "public" vlan 1 name "DEFAULT_VLAN" untagged 1-48,51-Trk1 ip address IP MASK exit ip authorized-managers serverIP ip authorized-managers workstationIP ip authorized-managers nagiosboxIP ip authorized-managers workstationIP spanning-tree Trk1 priority 4 ip ssh password manager Can you snmpwalk anything from the nagios box?
Hightower Posted February 25, 2010 Author Posted February 25, 2010 Just did an SNMPWALK from nagios to an APC UPS I have recently setup - works fine to that
RabbieBurns Posted March 6, 2010 Posted March 6, 2010 Hightower: Let me know how you go with nsclient++ on any win7 or win2008R2 servers (if youve got any), I cant get the service to install / auto start on those..
