Where are logs and error messages stored?
Look in /tmp/bessd.INFO, /tmp/bessd.WARNING, and /tmp/bessd.ERROR
My pipeline isn’t providing the right output. How do I tap the packets being forwarded in BESS?
BESS supports tcpdump on all module input/output gates. To do this, type tcpdump <MODULE> [in|out] [gate number] [any tcpdump flags/args you want] in bessctl. For example,
localhost:10514 $ tcpdump port_inc0 out 0 -ne | less
will show packets, including their Ethernet header. | less was used to not drown by tons of packets.
