Prompt how to take data from .1.3.6.1.2.1.25.3.5.1.2 if it OCTET STRING

hrPrinterDetectedErrorState OBJECT-TYPE
        SYNTAX  OCTET STRING
        MAX-ACCESS read-only
        STATUS  current
        DESCRIPTION
                "This object represents any error conditions detected
                by the printer.  The error conditions are encoded as
                bits in an octet string, with the following
                definitions:

                     Condition         Bit #

                     lowPaper              0
                     noPaper               1
                     lowToner              2
                     noToner               3
                     doorOpen              4
                     jammed                5
                     offline               6
                     serviceRequested      7
                     inputTrayMissing      8
                     outputTrayMissing     9
                     markerSupplyMissing  10
                     outputNearFull       11
                     outputFull           12
                     inputTrayEmpty       13
                     overduePreventMaint  14

                Bits are numbered starting with the most significant
                bit of the first byte being bit 0, the least
                significant bit of the first byte being bit 7, the
                most significant bit of the second byte being bit 8,
                and so on.  A one bit encodes that the condition was
                detected, while a zero bit encodes that the condition
                was not detected.

                This object is useful for alerting an operator to
                specific warning or error conditions that may occur,
                especially those requiring human intervention."

It appears you have little understanding of SNMP in general. The `hrPrinterDetectedErrorState` object is defined in RFC1759 (the RFC is more readable at this link). I presume you wish to poll printer information using SNMP. I assume that the IP address you're polling is that of a printer you don't need to know the name of the printer you just want the information from the printer You want to poll two objects. From the RFC: Read more... (1325 Bytes) This is a table, indexed by two integers. To read this table I would do the following: Read more... (3 kB) The output I get when querying the printer on my local LAN is: `C:\temp>perl -w checkprintercover.pl Cover description: Copier cover status: doorClosed(4) Cover description: Finisher cover status: doorClosed(4)` [download]	[reply] [d/l] [select]

Hi all. I neew you wisdom. I'm going to pool status information from network printers. I'm using code: `foreach my $k (@ips) { my $hostname = "10.0.0.$k"; my $password = "public"; my ( $session, $error ) = Net::SNMP->session ( Hostname => $hostname, +Community => $password , Version => 1 ); if (!defined($session)) { printf("ERROR: %s.\n", $error); next; } }` [download] in @ips I have last octet of IP's The problem is if one of the printer is swiched off the programm break Could you tell me what I'm doing wrong? Thanks in advance!	[reply] [d/l]
