Hi!
You really like to bend the rules, don't you :) Keep it up, I like it!
I tried this in a Juniper EX:
admin@EX2200# show snmp | display set
set snmp community public authorization read-only
set snmp community test authorization read-only
set snmp community "test\\" authorization read-only"

Hi!
What are you trying to accomplish? Is Centos running on the switch or a
system trying to read SNMP from a switch? Giv us some sample outputs.

Hi again!
If that's all you need, you do a walk with PHP (or faster alternative)
and push the data into a database with a timestamp. From there you can
monitor the links as often as you like, just as long as you remember
that the data you read is as old as the pollings feeding the dB with data.
Hi!
Yes, lots of things to consider... I have done some information
gathering on CMTSes (cable modem routers) reading out several thousamd
parameters. In general I can say that an snmpBULKwalk (command line) or
its equivalents in other languages are MUCH faster than reading
individual objects
Hi!
As a general suggestion, do you allow reading the entire (or the same
part of the) MIB tree? It's not uncommon to have setups that set
specific "views" in the SNMP setup.
Do an snmpbulkwalk of the entire "enterprises" tree to see how much that
differs:
/usr/bin/snmpbulkwalk -v2c -c ***
Hi!
Just like JMJ wrote, the device that is supposed to answer the request
has not implemented that specific OID/MIB tree. If you run the walk
detailed below, you'll see that it jumps directly to .1.3.6.1.4.1.8072.2
and never dives into .1.3.6.1.4.1.8072.1 since the first OID the SNMP

Hi!
It is sufficient to just copy the file as you dedcribe. Just make sure you have
an unbroken chain of references to the root of the MIB tree. If you have a
reference in your file to "enterprises" for instance, you should be fine.
You can also put the file in another dir and append that path w
Hi!
Just a thought: do the checks succeed or is the high number of open
files due to unsuccessful polls that keep hanging around retrying? If
so, try to decrease the timeout and number of retries. I think there are
often ridiculously high timeout limits in SNMP NMS software. Who wants a

Hi!
Why would you need a PEN at all? You can always use the experimental
tree, starting with .1.3.6.1.3. in the OID. You can then use a personal

Hi!
I'm not an expert of pass_persist, but I think you only need to specify
this line:
pass_persist -p1 .1.3.6.1.4.1.2021.13.16 /opt/aac/bin/snmp_ipmi_bridge.py
It will pass all requests in the .1.3.6.1.4.1.2021.13.16 tree to the

No, SNMP is not the way to go. I can't think of any device that can be
ordered to renew the IP address via an SNMP command. The two are simply
not that tightly related.
Clients generally renew the DHCP lease after half the lease time
assigned by the DHCP server. If that renewal fails, th

The obvious solution would be to stop using Windows and start using a

Now, that's an interesting issue, just my thing! Assuming you have a way
of gatering data (as you indicate) using a script, you can make that
data snmp readable using snmpd and the "pass" or "pass_persist" feature.
What you need to do:
1 - Edit /etc/snmp/snmpd.conf and add the following line:

I think you need to explain a little more in detail where this timeout
occurs. What SNMP manager do you use? If you just perform standard
queries from the command line, you can use the following options to
tweak the timeout:

Hi!
I see no reason why this shouldn't work:

PowerNet-MIB::iemStatusProbeCurrentTemp.2
but this:
snmpget -v2c -c public 10.10.70.40 .1.3.6.1.4.1.318.1.1.10.2.3.2.1.4

Sometimes people on this list proudly state that "you always get an answer to

Hi again!
Another way of reducing polling time is to have multiple jobs polling
modems, say 4 jobs:
Job 1: Polls modems with IP modulo 4 = 1 (10.0.0.1, 10.0.0.5 and so on)
Job 2: Polls modems with IP modulo 4 = 2 (10.0.0.2, 10.0.0.6...)
Job 3: Polls modems with IP modulo 4 = 3 (10.0.0.3, 10.0.0.7
Hi!
I assume the SNR needs to be calculated at that specific point in time and
that can take a little while. RX power is probably easier for the modem to
keep track of internally.
I tried 100 reads using a bash script:
time for (( i=0 ; i-100 ; i++ )) ; do time snmpget -v2c -c public
172.19.11.2
Hi!
What if you replace "head -29 walk.txt" with "head -100 walk.txt | tail
-29" to get another set of OIDs? Still 29 OK not 30? In that case, it's
definitely D-link just supporting 29 OIDs just because they didn't feel
more was required.

Hi!
First of all, use snmpbulkwalk as much as you can on SNMP v2c or v3
devices, it is much faster than snmpwalk.
root@fw01:~# head -150 walk.txt | cut -d' ' -f1 | xargs snmpget -d -r 0 -v
2c -c public 10.67.11.254
Too many object identifiers specified. Only 128 allowed in one request.
OK, 128 i
I think you only installed the Net-snmp application, not the libs for it.
Someone else can probably guide you all the way if necessary.

Hi!
If you're going to create a value after you get it via the SET, does it
matter what you reply to the GET? If possible, reply with an empty
string, or some other pre-defined string of your choice instead of
replying NONE.

Hi!
First of all the obvious: is the manager REALLY coming from IP
192.168.1.50 when the packets hit the RHEL box? No NAT in between? No
dual NICs or IPs? Just to make sure:
tcpdump -nnvv -c 10 port 161
Then try to access the RHEL box with SNMP from the manager. If source IP
is really 192.1
Hi!
Of course it is possible...
snmpbulkwalk -v 2c -c public 172.19.13.13 -m ""
-m tells the snmp command where to look for MIB files and -m "" tells it
to look nowhere!

Hi!
Is it "legal" to have a value assigned to an OID that has a child like
this:
.1.3.6.1.3.123.1 = Integer 1
.1.3.6.1.3.123.1.2 = Integer 1
or is there a rule saying that a parent (.1.3.6.1.3.123.1 in this case)
cannot have a value? We base an extension on this, but another piece of
