Thanks very much for the suggestion, I'll try that. I've been surprised how much information I get from iptraf-ng, which I only discovered recently. I knew about "arp -a", but I'm told I should be using "ip neigh". However, that doesn't give the name of each device on the network (if known), as arp does. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin
