Hejsa

Jeg har en debianboks med to netkort i (2 stk. skod RTL8139A) til at lege
router.
Jeg har så forsøgt at lave nogle grafer over trafikken på kortene ved hjælp
af MRTG. Det er gik fint, troede jeg, indtil jeg opdagede at   MRTG ikke
registrerer den indgående trafik (som i: den viser f.eks. 5 kbit ind på
eth1, når jeg henter en iso med 60 Mbit). Jeg kan ved hjælp af "snmpwalk
.interfaces" se at ifInOctets for eth1 fint opdaterer, og selvfølgelig er
næsten lig ifOutOctets for eth0. MRTG kan fint måle udgående trafik.

Min opsætning i mrtg.cfg ser således ud:

Target[eth0]:
.1.3.6.1.2.1.2.2.1.10.2&.1.3.6.1.2.1.2.2.1.16.2:public@localhost
MaxBytes[eth0]: 12500000
Title[eth0]: Trafik på internt netkort
PageTop[eth0]: <H1>Trafik på internt netkort</H1>

Target[eth1]:
.1.3.6.1.2.1.2.2.1.10.3&.1.3.6.1.2.1.2.2.1.16.3:public@localhost
MaxBytes[eth1]: 1250000
Title[eth1]: Trafik på eksternt netkort
PageTop[eth1]: <H1>Trafik på eksternt netkort</H1>


Og lige en lille snmpwalk på .interfaces:

Er det nogen som kan se fejlen?
