[MASOCH-L] RES: RES: Problemas com mrtg / snmp

[Márcio A. Sepp]

Bruno,


Segui sua orientação e fiz o seguinte arquivo /etc/snmp/snmp.conf:

# cat /etc/snmp/snmpd.conf
com2sec mynetwork 127.0.0.0/8   public
group  MyROGroup  any           mynetwork
view  all    included  system
view  all    included  interfaces
access  MyROGroup ""      any       noauth    0      all    none   none
#



Agora, veja as saídas das duas views:

# snmpwalk -v 1 -c public localhost system
SNMPv2-MIB::sysDescr.0 = STRING: OpenBSD crypto.zyontecnologia.com.br 4.4
GENERIC#0 i386

SNMPv2-MIB::sysORUpTime.1 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.2 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.3 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.4 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.5 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.6 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.7 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysORUpTime.8 = Timeticks: (1) 0:00:00.01
SNMPv2-MIB::sysORUpTime.9 = Timeticks: (1) 0:00:00.01


Mas a saída para as interfaces continua a mesma. Veja:

# snmpwalk -v 1 -c public localhost interfaces
IF-MIB::ifNumber.0 = INTEGER: 0
End of MIB

No proprio arquivo da distribuição vem bastante exemplo (comentado),
basicamente você precisa de 4 coisas (mynetwork e MyROGroup sao nomes que
voce "bola", NETWORK substitua por sua classe C ou quem deseja acesso ao
snmpd. no exemplo, public é a palavra da community, pode usar outra que
quiser)

1) um com2sec (somente sua rede/24 vai poder acessar o servidor)

com2sec mynetwork NETWORK/24 public

2) um group

group  MyROGroup  any        mynetwork

3) um ou mais view (o que voce quer que seja visto, a palavra "all" sera
usado no access para identificar o que pode ser lido)

view  all    included  system
view  all    included  interfaces

4) um access para juntar tudo isso, tipo

access  MyROGroup ""      any       noauth    0      all    none   none
