goutmp - Minimal bindings to C stdlib pututmpx(), getutmpx() (/var/log/wtmp) and /var/log/lastlog

Any Go program which allows user shell access should update the standard UNIX files which track user sessions: /var/log/wtmp (for the 'w' and 'who' commands), and /var/log/lastlog (the 'last' and 'lastlog' commands).

Overview

Golang bindings for basic login/utmp accounting

Functions

func GetHost

func GetHost(addr string) (h string)

return remote client hostname or IP if host lookup fails addr is expected to be of the format given by net.Addr.String() eg., "127.0.0.1:80" or "[::1]:80"

func Put_lastlog_entry

func Put_lastlog_entry(app, usr, ptsname, host string)

Put the login app, username and originating host/IP to lastlog

func Unput_utmp

func Unput_utmp(entry UtmpEntry)

Remove a username/host entry from utmp

Types

type UtmpEntry

type UtmpEntry struct {
	// contains filtered or unexported fields
}

UtmpEntry wraps the C struct utmp

func Put_utmp
