I know next-to-nothing about Redhat 9, but ... > If i want to monitor, for example, the traffic on my network per protocol , i > mean, TCP, X11, HTTP, ARP, POP, etc, what should i do??. I want to configure > mrtg to monitor my firewall and i have some doubts: You need either to log netflow from your upstream Cisco router, or you need to run something like Ourmon (http://ourmon.cat.pdx.edu/ourmon/) which will provide equivalent stuff stored in rrdtool. MRTG, in a default installation, reads byte counters on your network interfaces. So MRTG doesn't see any protocol information -- just the byte counters. That isn't to say you *can't* get this information into MRTG -- anything is possible. For example, in FreeBSD, I make IPFIREWALL (ipfw) rules that identify anything I want -- IP, netblock, port, port range, etc. The ipfw rules have byte counters, which I can add up and feed to MRTG, to get per-protocol stats. But it's an entirely manual process, and I have to know exactly what I'm looking for in order to set up the ipfw rules to look for it. Likewise with MRTG -- you have to define your targets before you can build logs of their traffic. You'd have to come up with a solution that worked with your particular platform. Last I heard, Redhat didn't use ipfw. If it has something equivalent that will let you gather the stats you need, pouring the data into MRTG is just a SMOP.
