GOnetstat

Netstat implementation in Golang.

This Package get data from /proc/net/tcp|6 and /proc/net/udp|6 and parse /proc/[0-9]/fd/[0-9] to match the correct inode.

Usage

TCP/UDP

tcp_data := GOnetstat.Tcp()
udp_data := GOnetstat.Udp()

This will return a array of a Process struct like this

type Process struct {
    User         string
    Name         string
    Pid          string
    Exe          string
    State        string
    Ip           string
    Port         int64
    ForeignIp    string
    ForeignPort  int64
}

So you can loop through data output and format the output of your program in whatever way you want it. See the Examples folder!

TCP6/UDP6

tcp6_data := GOnetstat.Tcp6()
udp6_data := GOnetstat.Udp6()

The return will be a array of a Process struct like mentioned above. Still need to create a way to compress the ipv6 because is too long.
