snmp

[Patrick]

how can I use snmp to find the hostname of a host using just the IP?

You'd need to query the iso.org.dod.internet.mgmt.mib-2.system.sysName
object.
( 1.3.6.1.2.1.1.5.0 )

i'm new to this , how would I do that? thanks

You need to use an snmp query utility. SNMPUtil.exe from the resource kit
for example.

SNMPUtil GET %SNMPAgent% %CommunityName% .1.3.6.1.2.1.1.5.0
i.e.
SNMPUtil GET MyPC Public .1.3.6.1.2.1.1.5.0

If the community name is changed, I would need to know that to pick up
an info off of the box?

 

[Patrick]

what is the OID?

 

[Dusty Harper {MS}]

yes, you need to know the community name

Object ID. That is the number that I initially posted along with what it
means.

..iso.org.dod.internet.mgmt.mib-2.system.sysName
..1 .3 .6 .1 .2 .1 .1 .5 .0

 

[Patrick]

thank you, where can I find a list of all object id's used in snmp?

They are in the MIB files as well as defined in the RFCs
