How to display the data in a row of a table
Hi,
i can use snmptable to display the whole table, but
how to disply a row of table?
The type of table index is IpAddress and i set
the index via snmp_set_var_value() as the following:
_get_first[next]_data_point() {
...
vptr = put_index_data;
snmp_set_var_value(vptr, (u_char *)&addr_ip, sizeof(in_addr_t));
...
}
When i tried the following command for instance with index 230.0.0.1,
"snmpget -v 2c -c private recMCAddressTable.230.0.0.1"
i got:
"...::recMCAddressTable.230.0.0.1 = No Such Object available on this
agent at this OID"
What is the correct usage of snmp command to dispaly a row of table?
thanks.
Li-Juen

Though having said that, our internal architecture doesn't allow for multiple SETs to be processed at once for exactly reasons like this: dependencies. Thus you're actually safe to fire a bunch of SETs at the agent where a middle one is a key change. *but* you can still run into problems: 1) networks don't guarantee order delivery of packets. Thus, they could arrive out of order if fired off quickly. 2) there is no assurance that the keychange SET itself will fail if it is messed up or fails for some reason and every SET after it would fail because it would be using the newer key. The net-policy project on sourceforge is a side-project of mine that has a robust configuration engine that accounts for issues like this and one of the things we do there is make sure that SETs that go out are sent one at a time to the host.

Re: Net-SNMP w/ Solaris 10 libseaProxy/Extensions.so doesn't work!
On Tue, Mar 07, 2006 at 11:38:50AM -0500, Jean-Sebastien Morisset wrote: > Thanks Keith! Attached is the core file. The command used to generate it The problem here is that 5.3.0.1's definition of netsnmp_session is incompatible with the one in 5.0.9, against which the seaProxy module was built. Specifically, the community name is being overwritten with the maximum SNMP packet length by the seaProxy code (which intends instead to set rcvMsgMaxSize), then the _sess_copy function attempts to memmove from this bogus pointer. The changes that caused this appear to have been made in the 5.2 timeframe (5.1.3.1 looks like it's ok) with the addition of a few new fields to the session. It's not clear to me whether seaProxy's behaviour is allowed here (that is, whether netsnmp_session is intended to be an opaque type). The general Net-SNMP answer seems to be that it's allowed, but the Solaris answer might be different. If it's not allowed, the bug is in Sun's SEA code and we might fix it - I say might because the code has been Obsolete for a long time. If the behaviour is allowed, you just won't be able to use the old SEA stuff unless you rebuild it (once it's available) against newer Net-SNMP headers. This would also mean that Solaris SEA will never (term used loosely) be upgraded past 5.1.x, because the SDK interfaces are classified either Stable or Evolving - which is effectively the same as Stable - and thus we can't allow them to be broken in a minor release of Solaris. I'm investigating this right now, but the answer isn't going to help you much immediately anyway. In general I recommend that you not use SEA anyway, as it's EOF and has been for some time. I'd be curious to know what you're getting from it that you can't get from the standard and add-on Net-SNMP MIBs. -- Keith M Wesolowski "Sir, we're surrounded!"

For testing purposes, you could use iptables on linux to block the inform response. Alternatively on the manager system create an incorrect host route (route via loopback perhaps) to the device sending the inform. This will send the inform response to a black hole. Then again you can take the easy way out and shut off the trap receiver. That will stop an inform from being sent and you watch the inform packet arrive via tcpdump or other means of sniffing the wire. -- -- rouilj John Rouillard System Administrator Renesys Corporation 603-643-9300 x 111 --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

If you work on a system with "netlink" support (a linux system, for instance) and don't shrink from a bit of C coding you can make a solution that gives the alarms immediately, and costs absolutely nothing on run-time. The trick is to open a netlink socket and subscribe to link change messages. Then generate the alarms using the net-snmp C API interface. There is an example in one of the tutorials, and it works, I have tried it. 100-200 lines of code.
