so

ip.ip_p = 17 '\021'
ip.ip_dst.s_addr = 16777216
ip.ip_src.s_addr = 3649090094

i don't understand what 'set -o' (shell cmd ?!), you suggest, can do with that.

Note: as the debian box is a gateway with VPN, there are ipsec/freeswan and openvpn tunnels
Note2: even with -E, ntop doesn't use lsof (/usr/sbin/lsof) and nmap (/usr/bin/nmap) cf web config page, so where ntop supposes them to be ?
