Frequently asked questions ( 5 )

Is there any way to make IPTraf run in the background and collect statistics to a log file?

there was no elegant way of doing so. Version 2.1.0 and later have the -B command-line parameter to force IPTraf to dump all its screen output into oblivion and move into the background.

Does IPTraf run on FreeBSD?

IPTraf was designed from the ground up to use the Linux

PF_PACKET mechanism, not libpcap.

I try to start IPTraf but it tells me that is already active in another process?

Probably due to a faulty installation or abnormal termination. If you're sure you've installed the software properly, you may have stale lock files from a previous abort.

How to configure IPTraf but it tells me only the first instance can configure?

By this command you can clear the Issue the iptraf command with the -f parameter.

Why I get the error message "Unable to open raw socket" when using IPtraf?

you must be running version 2.2.x of the Linux kernel. Be sure to include it if you're compiling a custom kernel. The "Packet Socket" driver must be installed.
