Suse + SNMP

Hi everybody

I need help with with SNMP daemon for Suse Linux. The simple situation - a have to send traps to 2 hosts if something is wrong in my OS.

Config snmpd.conf:

[CODE]mta-in-00:~/bck # cat /etc/snmp/snmpd.conf
syslocation mta-in-00.localdomain
syscontact Customer Name admin@customer.com
sysservices 78

trapsess -v 2c -c “public” 192.168.47.1:8165
trapsess -v 2c -c “public” 192.168.47.2:8165
[/CODE]

Log:

But if something is wrong in my system - ethernet cables are removed, hdd is full, sendmail is shutdown - there is no any traps.

Of course, i don’t have any firewall, Iptables is clear
It looks that everyting is ok, but daemon doen’t know when and what to send. I guess i missed something.

I need your help :slight_smile: Thanks and br/// Ilya

This looks fine to me, and matches what the LAN trace shows; send stuff to
these two hosts on port 8165 (UDP). This apparently works since that’s
what the LAN trace shows.

I’m not sure what you are showing here. This is from the system that is
supposed to be SENDING the messages to the 192.168.47.(1|2) systems,
right? What do listening ports have to do with sending data? Nothing, so
this confuses me.

So it is working, and sending to the specified port. Are you listening,
on the other machines, on this non-standard port? I presume so.
[color=blue]

But if something is wrong in my system - ethernet cables are removed,
hdd is full, sendmail is shutdown - there is no any traps.[/color]

How are you determining that there are not any traps? If the network
cable is unplugged that may not be surprising (maybe snmpd is clever and
caches things… I do not know as I am not an SNMP expert) but if the
service is shutdown, and if that should normally cause a trap, then I
cannot think of why that would not work. Could you help a newbie
understand how to configure certain types of traps? Have you tried
continuing the LAN trace on this box when doing things like stopping the
service to see if an attempt is even made to send something (I presume so,
but would like confirmation on what “there is no any traps” really means)?

You really should use the ‘ip’ command, just for the record. ifconfig is
outdated (see its manpage) and has been for years.

Of course, i don’t have any firewall, Iptables is clear
It looks that everyting is ok, but daemon doen’t know when and what to
send. I guess i missed something.

I need your help :slight_smile: Thanks and br/// Ilya[/color]

Did you configure your system to send those other types of traps? See the
snmpd.conf manpage, but I stole this from there, which seems to imply you
need t specify something, at least to a newb like me:

Process Monitoring
The hrSWRun group of the Host Resources MIB provides information
about individual processes running on the local system.  The prTable of
the UCD-SNMP-MIB complements this by reporting on selected  services
(which  may  involve  multiple  processes).   This
requires that the agent was built with support for the
ucd-snmp/proc module (which is included as part of the default build
configuration).

proc NAME [MAX [MIN]]
monitors the number of processes called NAME (as reported by
" -acx") running on the local system.

If the number of NAMEd processes is less than MIN or greater
than MAX, then the corresponding prErrorFlag instance will be set to 1,
and a suitable description message reported via the prErrMessage instance.

Note:  This situation will not automatically trigger a trap
to report the problem - see the DisMan Event MIB section later.

If  neither  MAX nor MIN are specified, they will default to
infinity and 1 respectively ("at least one").  If only MAX is specified,
MIN will default to 0 ("no more than MAX").  If MAX is 0 (and MIN is not),
this indicates infinity ("at least MIN").
If both MAX and MIN are 0, this indicates a process that
should not be running.

procfix NAME PROG ARGS
registers a command that can be run to fix errors with the
given process NAME.  This will be invoked when the corresponding prErrFix
instance is set to 1.

Note:  This command will not be invoked automatically.

The procfix directive must be specified after the matching
proc directive, and cannot be used on its own.

If no proc directives are defined, then walking the prTable will
fail (noSuchObject).

Good luck.

ab has it right: snmpd will (except for some very basic traps concerning itself) not send traps all by itself, unless configuring “DisMan” properly.

Again from the snmpd.conf man page, a bit above from what ab quoted:

ACTIVE MONITORING The usual behaviour of an SNMP agent is to wait for incoming SNMP requests and respond to them - if no requests are received, an agent will typically not initiate any actions. This section describes various directives that can configure snmpd to take a more active role.
