Basic Configurations for TrapHandling
Hi Friends !, I am new to snmp so please guide me. I have a Cisco/Bay router,. I just want the interface up/down or traffic beyond certail levelshould generate a trap on Linux machine and linux machine should fire a program/script according to that. A small script maybe send a email. what are the config reqd on Cisco/Bay and what are the configs reqd on Linux. Thanx Regards Anil Linux iqs-anil 2.4.20-8 (RedHat 9) net-snmp-5.0.6-17 net-snmp-utils-5.0.6-17 perl-5.8.0-88

Re: Sending traps from an agentX subagent, and snmpd robustness
I asked last week how best to send traps from an agentX subagent, where the trap originates in a separate thread from the main SNMP thread. With Rob Storey's help I've arrived at the the following solution, which works fine so far. In summary, the main thread creates a pipe, and the main loop uses select() to wait until either the pipe or the net-snmp fd's are readable. The other threads write trap information to the pipe; when it's readable, the main thread reads the trap data from the pipe and calls send_v2_trap(). I couldn't use agent_check_and_process() to wait for events because it ignores fd's registered with register_readfd(). Only receive() in snmpd.c uses external_readfd[]. So I wrote a stripped-down clone of agent_check_and_process. In pseudo-code: - snmp_select_info() - add pipe fd to fdset - select() - snmp_timeout() or snmp_read() - run_alarms(), netsnmp_chek_outstanding_agent_requests() - read pipe if it's readable send traps A separate question. The main agent (snmpd) listens on TCP AgentXSocket localhost:705. If I do telnet localhost 705 and hit return, snmpd starts hard-looping and doesn't answer any more requests. Of course the telnet protocol will look like rubbish to an agentX protocol endpoint, but it shouldn't self-destruct. Has anyone else observed this. Netsnmp 5.1.2 on Solaris 8.

SNMP and CIM
Hi all, Any clues on where to get more data about CIM and SNMP interworking would be greatly helpful. I did some googling, I got CIM and LDAP interworking but not CIM and SNMP.

Re: Route Metrics
Hi, Thanks for the info. On our systems, the net-snmp version is 5.0.1 which doesnot have the ipCidrRouteNumber. Can I directly upgrade the snmp version to latest one with the rmp available on the net-snmp.org? Also, I have gone thorugh the walking a column of the ipRouteTable. The child for (like ipRouteDest) and counting the number ipRouteTable is ipRouteEntry which has many child nodes like ipRouteDest(1), ipRouteIfIndex(2), ipRouteMetric1(3), ipRouteMetric2(4), ipRouteMetric3(5), ipRouteMetric4(6) etc. snmpwalk through this ipRouteEntry gives the following results. RFC1213-MIB::ipRouteDest.0.0.0.0 = IpAddress: 0.0.0.0 RFC1213-MIB::ipRouteDest.127.0.0.0 = IpAddress: 127.0.0.0 RFC1213-MIB::ipRouteDest.172.17.12.0 = IpAddress: 172.17.12.0 Please let me know how to count the number of responses from this and also what would that response stand for?

Unfortunately, that object isn't implemented yes in net-snmp. The best bet that is currently going to work for HP-UX and Linux is going to be walking a column of the ipRouteTable (like ipRouteDest) and counting the number of responses. Warning: for machines with large route tables (several thousand routes), this will take a while, and the timeout may need to be set really high (like 30 seconds or more, depending on the table size). The inetCidrRouteTable, new in 5.2 for Linux (any volunteers to port to HP-UX or other platforms?), is much faster, at the expense of being a bit of a memory hog. -- Robert Story; NET-SNMP Junkie Support: http://www.net-snmp.org/ irc://irc.freenode.net/#net-snmp Archive: http://sourceforge.net/mailarchive/forum.php?forum=net-snmp-users You are lost in a twisty maze of little standards, all different. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.
