A new version of bwmon is out, fixing problems with recent kernels for which there is no more ip_conntrack module. As a replacement, the conntrack utility from conntrack-tools is used. You will have to enable conntrack accounting using sysctl:

sysctl -w net.netfilter.nf_conntrack_acct=1

Features

• Uses ip_conntrack or conntrack-utils to track connections
• Alternative, cross-platform "pipe" traffic monitor
• Easily customizable: Written in Python
• Combination of conntrack+pipe monitors possible
• Open Framework: Create new monitoring methods
• Support for SLA parameter input (bandwidth allocation)
• Support for SLA violation notification to external services
• Fully documented source code and user manual
• New in version 1.1: Support for conntrack-tools as replacement of the old ip_conntrack module (recent kernels)
