I experienced this bug on a Debian 5.0.6 x86_64 system, having at
For this I used the standard configuration of smnpd, except 2 things:
First: In /etc/snmp/snmpd.conf change lines 60 to 63 to look like this:
# sec.name source community
#com2sec paranoid default my_community
com2sec readonly 0.0.0.0/0 my_community
#com2sec readwrite default my_community
Second: In /etc/default/snmpd replace 127.0.0.1 with the ip of the
Now start snmpd (e.g. "/etc/init.d/snmpd start") and run (from any host
having ip access to the machine):
snmpwalk -c public -v1 HOSTNAME_OR_IP 184.108.40.206.220.127.116.11.1
If you do this immediately (maybe 5 to 15 seconds) after starting or
restarting snmpd it will show you the correct speed for the gigabit
Ethernet interface (should be IF-MIB::ifSpeed.2 = Gauge32: 1000000000
which is 1000Mb/s).
But about a short time later, the speed will show up as 10000000 which
I also looked up the speed using "ethtool eth0". It shows 1000Mb/s all
An Debian 5.0.5 system in a Qemu version 0.12.3 showed the same
behaviour for an rtl8139 network card.
The snmpd version 18.104.22.168 package in Ubuntu 10.04.1 (x86) shows the same
behaviour, but I DIDN'T changed snmpd.conf from "default" to "0.0.0.0/0"
and /etc/default/snmpd from "127.0.0.1" to the public ip.
The net-snmp package (version 5.5-9.1) in openSUSE 11.3 (x86) doesn't
not show this behaviour.
