Having said that there are two main reasons for not getting a response, the most likely cause of this problem is actually something else again.
The 'snmpwalk' command takes a point in the overall MIB tree, and tries
to display all the values that lie within this subtree. However, it
actually does this by issuing a series of "getnext" requests, until
the variable returned lies outside the subtree of interest. If the
very first request returns such an undesired value, then the command
will terminate, without having displayed anything at all.
If an expicit starting point is given to 'snmpwalk', then it is reasonably
clear what is happening, and that there is simply nothing in the subtree
specified. However, if 'snmpwalk' is called without giving an explicit
starting point, then it will display the contents of the 'mib-2' subtree.
It will not attempt to traverse any 'private.enterprise' subtree, such as
the UCD-specific objects (including any local extensions).
