AWK e log Syslog

[Kandango]

Colegas, preciso fazer um script para refinar esse tipo de log abaixo:

Esse script é do log dhcp do meu firewall, e eu precisava saber quem estaria online nos ultimos 5 minutos, sendo assim penso em fazer um script com AWK para refinar esse log, e gostaria de ter uma saída neste formato:

Usuário | IP | MAC | Data/Hora


se alguém puder ajudar, ficarei muito grato.

cat log | grep DH | awk {'print $9 $11 $1 $2 $3'}

Cara,

arp -a , mostra quem se comunicou com o seu host nos últimos 20 minutos aproximadamente. Acho que isso pode te ajudar.

Abraços,
