Hi, I can observe something strange with new UPS equipped with InsightPower SNMP card. I'm trying monitor it from Debian Etch (kernel 2.6.8) and net-snmp apps in version 5.2.3. For example:
[EMAIL PROTECTED]: ~]$ snmpget -v1 -c plmik01 ups1 system.sysName.0 Timeout: No Response from ups1. but if I turn on debug mode... [EMAIL PROTECTED]: ~]$ snmpget -d -v1 -c plmik01 ups1 system.sysName.0 Sending 44 bytes to UDP: [192.168.1.100]:161 0000: 30 2A 02 01 00 04 07 70 6C 6D 69 6B 30 31 A0 1C 0*.....plmik01 . 0016: 02 04 77 64 4E 5E 02 01 00 02 01 00 30 0E 30 0C ..wdN^......0.0. 0032: 06 08 2B 06 01 02 01 01 05 00 05 00 ..+......... Received 45 bytes from UDP: [192.168.1.100]:161 0000: 30 2B 02 01 00 04 07 70 6C 6D 69 6B 30 31 A2 1D 0+.....plmik01˘. 0016: 02 01 00 02 01 00 02 01 00 30 12 30 10 06 08 2B .........0.0...+ 0032: 06 01 02 01 01 05 00 04 04 55 50 53 31 .........UPS1 As You can see, response came from UPS: 45 bytes with expected string "UPS1". I tried to catch responses with tcpdump: [EMAIL PROTECTED]: ~]# tcpdump -n host ups1 22:03:02.373063 IP 10.197.84.43.38697 > 192.168.1.100.161: C=plmik01 GetRequest(28) .1.3.6.1.2.1.1.5.0 22:03:02.381429 IP 192.168.1.100.161 > 192.168.1.43.38697: C=plmik01 GetResponse(29) .1.3.6.1.2.1.1.5.0="UPS1" As You can see, answer looks good. I don't know why snmpget and snmpwalk always give me timeout answer. I think it's something specific in UPS SNMP card. What I tried: - on the same client upgrade snmp apps package to 5.3.1 (form Debian Sid) - timeout, but responses are coming - on the same client download net-snmp-5.4.tar.gz and compile it myself - timeout, but responses are coming - on another Debian Etch server - the same problem - on another Ubuntu station - the same problem - I installed net-snmp-5.4.0-1.win32.exe on Windows XP - work fine - I installed net-snmp-5.4.0-1.win32.exe on Windows 2003 Server - work fine as well - I prepared simple Perl script using Net::SNMP on Debian - timeout, but I'm able to catch responses - set option -t with big value on Debian - it doesn't help Generally, I can retrieve answer from UPS using net-snmp apps on Win OS, but I have a problem to do this using net-snmp apps on Linux based OS. There is no problems with firewalls, LAN, routing and something like that. Thanks for all Your suggestions. best regards, wilku -- Artur WILCZEK <[EMAIL PROTECTED]> ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
