question regding monitoring

[kcpant]

Hi friends,

some questions regarding monitoring traffic on my linux machine:

my linux server works as a proxy, mail server and iptables with NAT is also configured on it.two ethernet interfaces are installed on it, first is connected to external link to DSL router, and second is connected to internal network. now,
1. is there any tool which can be used to easily analyze iptables logs? i have tried one , firelogd, but it's not working. can anybody please tell me how it can be configured on RHL 8.0? or any other tool?
2. how can I run MRTG on this system, to give me graphs about traffic passing through my Internet interface( connected to DSL)?I have installed snmpd , but when I check it by snmpwalk, it is not responding. I know that best way is to configure my DSL router for snmp, but this router I suppose does not support SNMP ( it's a zyxel a600 DSL router).please guide me how can I achieve the goal of monitoring traffic on my WAN interface using MRTG.

thanks & regards

Hi kcpant,

what kind of analysis do you want to do ?

Have you ever heard about logwatch ?

About MRTG I gave you a link for a version that complains with your RH8 in another thread.

Hi Xyko,

I had managed to install & configure MRTG on my server on sat itself( I'm sorry, I haven't informed forum about that).

I'll try logwatch now...

Thanks & regards
