Функции SNMP

For my purposes in PHP coding, I have the following SNMP options set, always.  These aren't documented very well in PHP's docs, but they make dealing with the SNMP results a LOT easier:<?php// Return back the numeric OIDs, instead of text strings.snmp_set_oid_numeric_print(1);// Get just the values.snmp_set_quick_print(TRUE);// For sequence types, return just the numbers, not the string and numbers.snmp_set_enum_print(TRUE); // Don't let the SNMP library get cute with value interpretation.  This makes // MAC addresses return the 6 binary bytes, timeticks to return just the integer// value, and some other things.snmp_set_valueretrieval(SNMP_VALUE_PLAIN);  ?>

Here's a fresh list of API for SNMPv1, SNMPv2c, and SNMPv3 as of PHP 5.2.4:SNMPv1------string snmpget(string host, string community, string object_id [, int timeout [, int retries]]);string snmpgetnext(string host, string community, string object_id [, int timeout [, int retries]]);array snmpwalk(string host, string community, string object_id [, int timeout [, int retries]]);array snmprealwalk(string host, string community, string object_id [, int timeout [, int retries]]);bool snmp_get_quick_print(void);void snmp_set_quick_print(int quick_print);void snmp_set_enum_print(int enum_print);void snmp_set_oid_output_format(int oid_format);int snmpset(string host, string community, string object_id, string type, mixed value [, int timeout [, int retries]]);SNMPv2c-------string snmp2_get(string host, string community, string object_id [, int timeout [, int retries]]);string snmp2_getnext(string host, string community, string object_id [, int timeout [, int retries]]);array snmp2_walk(string host, string community, string object_id [, int timeout [, int retries]]);array snmp2_real_walk(string host, string community, string object_id [, int timeout [, int retries]]);int snmp2_set(string host, string community, string object_id, string type, mixed value [, int timeout [, int retries]]);SNMPv3------int snmp3_get(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);int snmp3_getnext(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);int snmp3_walk(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);int snmp3_real_walk(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);int snmp3_set(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id, string type, mixed value [, int timeout [, int retries]]);General-------int snmp_set_valueretrieval(int method);int snmp_get_valueretrieval();int snmp_read_mib(string filename);SNMPv3 options--------------SNMPv3 offers a different authentication/authorization scheme than previous versions of SNMP.  To aid in using the API listed above, here is a brief explanation of each of the unique parameters used in the snmp3_* functions.$sec_name - the "username" used for authentication to the system$sec_level - the authentication scheme ('noAuthNoPriv', 'authNoPriv', or 'authPriv')$auth_protocol - the encryption protocol used for authentication ('MD5' [default] or 'SHA')$auth_passphrase - the encrypted key to use as the authentication challenge$priv_protocol - the encryption protocol used for protecting the protocol data unit ('DES' [default], 'AES128', 'AES192', or 'AES256')$priv_passphrase - the key to use for encrypting the protocol data unitThere are good code snippets available on http://forums.cacti.net/about5403.html for more information.
