cgolmnfct

Go wrapper of libnetfilter_conntrack subset using cgo, under heavy development

sample

see examples

installation

Need running ``mktypes.sh'' before build.

Need delete tesglib/types_linux.go or comment out the lines on testing I do not know how to avoid this...

requires

• libmnl, libnetfilter_conntrack

• cgolmnl (https://github.com/chamaken/cgolmnl)

links

• libmnl: http://netfilter.org/projects/libmnl/

• libnetfilter_conntrack: http://netfilter.org/projects/libnetfilter_conntrack/

struct

All of internal structs are opaque as...

• struct nf_conntrack / Conntrack
• struct nf_expect / Expect
• struct nfct_bitmask / Bitmask
• struct nfct_labelmap / Labelmap
• struct nfct_filter / Filter
