snmp on router

Hi all!
I have a router that has snmp so I'm trying to use it, but I never get a
response from the router. Also, there is no snmp port opened, so does that
mean the router simply doesen't listen to a snmp request?
How ca I tell if snmp works on the router? Configuration lets me choose its
comunity.

Thanx!

What programs are you using, what router are you using? Have you
configured the router to accept snmp requests? Here's a smaple of an
snmp request (every device supports this one, I think):

$ snmpget router public system.sysUpTime.0
system.sysUpTime.0 = Timeticks: (44188600) 5 days, 2:44:46.00

OR

$ snmpget router public .1.3.6.1.2.1.1.3.0
system.sysUpTime.0 = Timeticks: (44216400) 5 days, 2:49:24.00

where router is the name or ip address of the router and public is the
SNMP community string (public is the default read-only string).

When I try using snmpget with the wrong password (mine is not set to
public) I get:

$ snmpget ng public system.sysUpTime.0
Timeout: No Response from ng.

You are correct that snmp is on 161 (snmp-trap is 162 and that's stuff
that get sent to logs not the snp requests and responses). Double
check your password (same case et al) and make sure that the USR is
setup to allow snmp requests from your local LAN (usually a
192.168.x.x addr). Good Luck.

Oh, have you checked with USR?
