The thread can build PDUs and bind variables to PDUs, as it performs its duties. I tried also to uncomment Code: #rocommunity public localhost and changed localhost by centreon server ip, same error: error when getting SNMP version: no response from remote host My command is Then you can use the C method to encode and send SNMPv1 traps. An undefined value is returned if some error happens during encoding or sending, or if no matching response is received after the wait/retry schedule is exhausted.

If this is too small, then a table walk will need unnecessarily many request/response exchanges. fdasfdsfsd View Public Profile View LQ Blog View Review Entries View HCL Entries Find More Posts by fdasfdsfsd Thread Tools Show Printable Version Email this Page Search this Thread Advanced Monitors as like nothing happend. http://www.webhostingtalk.com/showthread.php?t=34580 Differences Between Traditional API and Single API Usage 5a6 > void *sessp; /* sessp = snmp_sess_open(&Session); > if (sessp == NULL) { 19c20,22 < /* Pass sptr to snmp_error from here

This document describes the operation of the SNMP Library with a focus on its session management functions. Have I just overlooked anything simple? It *shouldn't* matter but lets go ahead and add this line to your configuration as well..Code: [Select]set admin manager-ip 192.168.1.250 255.255.255.255
So, just to compile our check list..We have ensured that:-SNMP

Sessions created using the Single API do not interact with other SNMP sessions.

  1. Closing a Session releases the memory and system resources used for these purposes.

  4. The MIB parsing functions use global shared data and are not multi-thread safe when the MIB tree is under construction.

In SNMPv2 traps and informs, the equivalent information is contained in the bindings. return undef unless defined $req; $timeleft = $timeout; while ($retries > 0) { $this->send_query ($req) || return $this->error ("send_query: $!"); # IlvJa # Add request pdu to capture_buffer push @{$this->{'capture_buffer'}}, $req On most POSIX-like systems this will be set to ### MSG_DONTWAIT, on other systems we leave it at zero. ### my $dont_wait_flags; BEGIN { $ipv6_addr_len = undef; $SNMP_Session::ipv6available = 0; $dont_wait_flags return undef unless defined $req; $this->send_query($req) || return $this->error ("send_trap: $!"); return 1; } sub request_response_5 ($$$$$) { my ($this, $req, $response_tag, $oids, $errorp) = @_; my $retries = $this->retries; my

Once copied, changing that input structure's data has no effect on the opened SNMP Session. If you choose to use Traditional API calls, call them from a single thread. its range is from -(2^31) to (2^31)-1. If you walk a table multiple times, and the size of the table is relatively stable, you should use the return value of C (which is the number of rows it

Reload to refresh your session. Previous ## versions of the code simply did a bytewise comparison ("eq") of the ## two sockaddr_in structures, but this didn't work on some systems ## where sockaddr_in contains other elements Applications that call snmp_sess_init() do not need to read MIBs nor setup environment variables to utilize the Library. If it is Linux Related and doesn't seem to fit in any other forum then this is the place.

Unfortunately, the SNMPv3 support was added about the same time as the thread support and since they occurred in parallel the SNMPv3 support was never checked for multi-threading correctness.

This version uses the ``powerful C operator'' to retrieve many table rows with each request. It is useful on hosts that have multiple addresses if a specific address should be used, for example because of firewall rules. This can be accomplished by invoking snmp_sess_init from the main thread and discarding the buffer which is initialised. 3. All Rights Reserved.
