How to get SNMP data using pysnmp?

问题 I want to get snmp data by using python pysnmp module. I was using command line to get SNMP data but now I want to read it using pysnmp module. SNMP command - snmpwalk -v 1 -c public <ip address>:<port> xyz::pqr I was using command like above. Now I tried something like below - import netsnmp def getmac(): oid = netsnmp.VarList(netsnmp.Varbind('.1.3.6.1.2.1.17.7.1.2.2.1.2')) res = netsnmp.snmpgetbulk(oid, Version = 1, DestHost='ip', Community='pub') return res print getmac() I'm facing error

net-snmp parse code, How to parse MIB?

问题 I am learning net-snmp code-base. To parsing MIB. In parse.c and parse.h code keeps a hash bucket. (indexed bucket (tree list)) . There is also a tree structure, Which contains a next pointer pointing to Next node in hashed list of names. struct tree{ . . struct tree *next; // Next node in hashed list of names int modid; // The module containing this node } I printed the MIB, SNMP-FRAMEWORK-MIB:snmpFrameworkMIB(10) type=24 Next-> ' ipSystemStatsHCOctetGroup ipSystemStatsOutFragReqds

is it possible to programatically change an executable name (ucmd) of a unix process?

由 只愿长相守 提交于 2019-12-06 08:59:35
问题 Is it possible to programatically change an executable name (ucmd) of a unix process as reported by ps? unix/POSIX way would be nice but Linux specific solution would suffice. I want to change what is reported here > ps -o ucmd CMD zsh ps not this, this I know ;) > ps -o command COMMAND zsh ps -o command thanks P.S. Not trying to create a rootkit, its just that net-snmp looks at this name when checking processes and my program has a different name when called from init and directly from /etc

Linux snmp导入MIB库

由 柔情痞子 提交于 2019-12-05 17:33:56
Linux 中所使用的net-snmp自带了一些标准的MIB，但是世界上支持snmp的设备有无数种，各厂家都有自己的定义，这些定义不可能都包含在net-snmp自带的MIB中，因此，想要正确轮询一个这样的设备，必须载入厂家自己的MIB文件。 一般我们下载回来的MIB文件可能后缀名为.mib，为了清晰起见，一般改成 MIB_NAME.txt这样的形式，当然不改也可以，这个MIB文件叫什么名字无关紧要。 系统要载入一个MIB文 件，net-snmp必须知道从哪里载入。默认情况下是下边两个目录: 1. $HOME/.snmp/mibs 2. /usr/local/share/snmp/mibs 不过也有些发行版会改变这个默认路径，那么可以用下边两种方法之一获取它所使用的路径。 1.如果系统安装了net-snmp-config: # net-snmp-config --default-mibdirs 2.如果未安装net-snmp-config: # snmptranslate -Dinit_mib .1.3 2>&1 |grep MIBDIR init_mib: Seen MIBDIRS: Looking in '/root/.snmp/mibs:/usr/share/snmp/mibs' for mib dirs ... 二、net-snmp加载MIB文件方法

Get OID's type (syntax) from MIB using Net-SNMP API

由 故事扮演 提交于 2019-12-05 15:36:46
How can I get the syntax type and read/write access for an OID using NET-SNMP API? I am writing an SNMP tool that reads and sets values on a remote machine using SNMP protocol. Before setting the value, I need to check its type and access permissions (whether it is allowed to write this value on the server or not) from the MIB file. Unfortunately, I could not find any mention regarding how to do this in the Net-SNMP documentation. Roughly speaking: oid name[128]; size_t name_length = OID_LENGTH(name); strict tree *tp; read_objid("sysContact.0", &name, &name_length); tp = get_tree(name, name
