SNMPWALK Problem for 1.3.6.1.2.1.1 on netcomro@172.27.252.3::::::v4only
at /usr/bin/cfgmaker line 950
WARNING: Skipping netcomro@172.27.252.3: as no info could be retrieved

I saw a snmp service(snmptrapd) down. I put it up and the result was the same. ;-(

Traps it seems use port 162

http://catb.org/~esr/faqs/smart-questions.html

Here we Can't use telnet, I tried ssh onstead and seemed working.

I ask to see if The router is accepting both 161 and 162 , also along the route.
They will do it afternoon today and I post the results here.
Tks

nc ?

Didn't understand what it means.

netcat # since there's no telnet client.

How was this cfgmaker installed exactly?
What OS and build is this on?
What version of snmpd?

Can you snmpwalk manually to 172.27.252.3 for the 1.3.6.1.2.1.1 OID?
version 2 I suspect.

The log isn't enabled.
Comes an error: No security name specified.

Show us the command used please.

Two tries:
snmpwalk 172.27.252.3 1.3.6.1.2.1.1
No log handling enabled - turning on stderr logging
snmpwalk: No securityName specified
And
snmpwalk 172.27.252.3
Same result

I had used the second to test SNMP connection in the past.

Is the snmpd.conf on 172.27.252.3 configured for access ?\

Maybe it's time I ask you what you are trying to achieve.
What is the goal?

You're using snmpwalk incorrectly:
Example:
So I refer you to http://www.net-snmp.org/

So, on 172.27.252.3 you'll need to configure the "community" (you used "netcomro" earlier?)
and what they'll have access to.

Lots of examples on the web:

I asked them to verify for me, they will answer this afternoon.
Is there any way to test and tell them the problem is there ?

Test what?
I have only your improper use of the snmpwalk command.
Edited: See above^

Also:
You didn't answer:

So, I'm waiting on that before I invest too much more time.
Make certain ports 161 and 162 are open on the snmp host being queried and the client machine doing the query.

I don't have NC command.
The Community is correct.
