Hi, Sorry about the mistake, I was asking for hints about the cache timeout values. It can't be modify when changing the xxx_TIMEOUT define statement ( ie.e stays at 60 seconds ) Any hints?

Errr... that second form looks invalid. mib2c only takes a single root OID. It would either be mib2c -c mib2c.table_data.conf my or mib2c -c mib2c.table_data.conf myTable Not both.

snmpd on ARM, error with /proc/bus/pci
Hello all, I am using snmpd on a ARM based target running Linux. This target have no PCI. When I try to start snmpd I have the following error: /etc/init.d/snmpd start Starting network management services:pcilib: Cannot open /proc/bus/pci pcilib: Cannot find any working access method. snmpd. Of course, as I have not PCI on my target, I have no pci entry in /proc/bus. I have looked inside the configure script of net-snmp and libpci is needed for if-mib description. How could I properly disable this ?

mib2c on entire MIB -- gluing the bits together
Hi, I'm a new Net-SNMP user, learning how to code my first MIB subagent for a pre-written MIB file. I gather, from searching these archives, that mib2c is intended to be run on a single MIB node with a single type of data, so if I had the following MIB: myMIB myMIB.scalar myMIB.table I would run mib2c on myMIB.scalar and again on myMIB.table, generating two sets of .c/.h files, correct? What do I then need to do to glue the bits together into a working subagent? Presumably I somehow need to run mib2c on the root node, myMIB, to generate code that registers and delegates calls to the scalar and table nodes. And what about the subagent wrapper that talks to the master?

mib2c.table_data.conf, cache timeout period does'nt seems to change.
Hi, For tables implemented with the mib2c.table_data.conf script (option 1, for cache enabled) the default timeout period of 60 seconds is working well but when I lower that value with the #define statement (5, then 30) the timeout period stays steady at 60 seconds) The code for the table is generated with the script mib2c -c mib2c.table_data.conf my myTable, option 1) Hold a local cached copy of some external data which is then used to service incoming requests. mib2c -Scache=1 -c mib2c.table_data.conf myTable I'll try some other stuff today.

UDS
Hi all, I have 2 questions regarding UDS in SNMP: 1. Does SNMP ( any version ) support abstract names? if so, from which version? and how they are configured? Note: UDS abstract name is a UDS socket which is opened in the process memory rather than as a file path. 2. snmpd opens /etc/snmptrap UDS. What is the reason for this socket and how can one disable it?

Intermittent time-outs
Hi everyone!
Here's a pretty weird problem. We have a NMS server and a bunch of
servers and equipment to keep an eye on with the help of net-snmp.
Intermittently snmpwalk will fail to get data from one of the servers
and end its attempt with this:
[root@nms ~]# snmpwalk -v2c -c $PASS $SERVER
Timeout: No Response from $SERVER
What happens to snmpd on the server that is being monitored is the
following (in strace parlance):
[root@server ~]# ps axuwf |grep snmp

My first thought was to check the Internet link (yes, the server is
not on the LAN or in DMZ), which looked fine by the way, and the
server actually is a SIP server serving quite a bit of calls, but
there were no issues related to poor link quality with the calls at
all.
I then tried to snmpalk localhost right on the server where snmpd is installed:
[root@server ~]# snmpwalk -v2c -c $PASS localhost
Timeout: No Response from localhost
Now, this timeout lasts only for as long as (approximately) 20-30s.
The problem is that Cacti running on NMS server has stopped to draw
graphs since a long time. That is why I set out to figure why it was
so. However, I couldn't pinpoint exactly what the problem is so far.
Interestingly, the graps started reappearing again, but they're kind
of incomplete. It looks to me as if Cacti poller fails to communicate
with the server's snmpd for whatever reason. See screenshot at
http://i.imgur.com/PI3yE.jpg to get a visual on these graphs and alleged
incompleteness. Note, that this graph used to work just fine for some
time. This is the server that was set up and configured by someone
long before me, so I don't know whether anything has been changed.
I've been told that there were no changes to the configuration of the
NMS but the problem arose simply out of the blue. Can't tell how
accurate that information is, but let's just assume it is.
I've no clue how to further troubleshoot this problem and whether the
timeouts I see in strace are the problem. Thought I'd write this
message and hopefully someone will be able to help.
Here's the system information where snmpd runs:
[root@server ~]# uname -a
Linux server 2.6.18-164.el5PAE #1 SMP Thu Sep 3 04:10:44 EDT 2009 i686
i686 i386 GNU/Linux
[root@server ~]# cat /etc/redhat-release
CentOS release 5.3 (Final)
[root@server ~]# yum list installed |grep snmp

net-snmp-perl.i386 1:5.3.2.2-5.el5_3.2installed
net-snmp-utils.i386 1:5.3.2.2-5.el5_3.2installed
Btw I checked some other hosts that has pretty graphs, and there are no
these time-outs happening there. The configs for these two hosts are not
awfully different, in fact pretty similar.
I'd appreciate any help here, 'cuz I'm literally clueless as to how to get rid
of these timeouts.

help for newbie config: aliases and host-specific configs
I basically need to do: $ snmpwalk -v2c -mALL -c rescore-public 128.x.y.z From what I gather in the man pages I should be able to do $ snmpwalk alias:myalias and/or $ snmpwalk myalias I can specify those options as the default in ~/.snmp/snmp.conf. But when I try to make them host-specific, nothing works. I've tried two approaches: First, adding "alias myalias 128.x.y.z" in snmp.conf and putting everything else in hosts/128.x.y.z.conf (and also hosts/myalias.conf and alias:myalias.conf). With -DALL I can see that hosts/128.x.y.z.conf is actually parsed, and the version, for example, is accepted, but then I see securityName not specified. Adding -v2c to the command line fixes this. So I'm not sure why the host-specific settings are not being honored. The second approach I've tried is to have no global ~/.snmp/snmp.conf file at all, and a hosts/myalias.conf with "transport 128.x.y.z" This has similar results to the alias method. I am not subscribed to the list, so please be sure to explicitly include me on any replies.
