Re^3: Reading IP from a file and SNMP

[Anonymous Monk]

That's good news! Could you be more specific or just show me some lines of code. I was reading the docs of net-snmp and tehre was only an exapmle of C async poll. Thanks!

there are a couple examples in the net-snmp/perl/SNMP/examples directory. there's also a bit in the SNMP perldoc. for the most part you just add a callback to the get command (which will get called when the reply comes back) and then call SNMP::MainLoop.

use SNMP;
my $session = SNMP::Session->new( ... );

sub callback {
  if ( !defined( $_[0] ) {
    warn "request timed out: $session->{ErrorStr}\n";
  }
  # do something with VarbindList $_[0]
}

$session->get( [[ $oid ]], \&callback );

SNMP::MainLoop();

my code is a bit more complex, taking a list of hosts, a number of outstanding reqests and a set of OIDs. it returns all of the info in a hash. i'll see if i can clean it up a bit for posting.
