Salah satu tool monitoring trafik yang lumayan menarik untuk di coba adalah smokeping. Aplikasi ini khusus di buat untuk mengamati paket loss, latency dan jitter. Berikut cara installasinya,

root@brokenz:~# aptitude install smokeping curl libauthen-radius-perl libnet-ldap-perl libnet-dns-perl libio-socket-ssl-perl libnet-telnet-perl libsocket6-perl libio-socket-inet6-perl apache2

Sedikit ubah settingan konfigurasi di /etc/smokeping/config.d/General

root@brokenz:~# vi /etc/smokeping/config.d/General

*** General ***

@include /etc/smokeping/config.d/pathnames

# Please edit this to suit your installation
owner    = Falko Timme

cgiurl   = http://xxx.xx.xx.xx/cgi-bin/smokeping.cgi
mailhost = smtp.gmail.com
# specify this to get syslog logging
syslogfacility = local0
# each probe is now run in its own process
# disable this to revert to the old behaviour
