snmpd crash when started with udp, dltsudp, tlstcp

I am running net-snmp 5.8 r0. I can get snmpd, snmptrapd and snmpget working with dtlsudp and tlstcp. Except for some corner cases: If I have a trap session defined in the snmpd.conf file, but the snmptrapd is not running. snmpd gets a SIGSEGV at startup time. (If I start snmptrapd first, then ev

Re: Finding mib2c

If you extracted the tarball, then you can find it in the local directory. If you have installed it on your system (assuming a make install was done) /usr/local/bin/mib2c At least that is where it is on my Ubuntu install. On Tue, Dec 17, 2019 at 9:53 AM Philip Rowe wrote: > Hello, > > > > I am

Re: snmp agent responds to v3 requests and v2c only requests

You should be able to do what you have laid out. Here is a possible starting point. To restrict who can access SNMP and what community string they use: com2sec IP/CIDR For example: com2sec mysec 10.10.10.0/24 'my_string' all access from any IP on that subnet to get specific IP: 10.10

Re: Snmpv3 users details are not deleting from /var/net-snmp/snmpd.conf file

I am no expert, but do deal with creating and deleting SNMP v3 users in my job. You may have to use the tool, snmpuser to remove V3 users without restarting the snmpd daemon. >From the man page: " *snmpusm* is an SNMP application that can be used to do simple maintenance on the users known to an

Re: Automatic update of snmpd.conf to show new users

I am more of a user of the net-snmp library so take what I say with skepticism. The snmpusm should be updating the usmUserTableby sending messages to the snmpd to do the work. You can query this table to verify that the users are created in it. Once in this table, I would suspect that these users

Re: Re-registering sysContact and sysLocation with subagent

Someone just this month asked about taking control of the system description. I would suspect that sysContact and sysLocation would follow the same way. Their solution was to unregister the OID then register your own handler. unregister_mib() API. https://sourceforge.net/p/net-snmp/mailman/mess
