it's really weird my netstat show an host in the routing table that is not in rc scripts... is possible that this host is trying to do something strange like... getting my IP address or something ?? someone can have an idea on why my routing table is like that ?? Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 137.204.49.254 UGSc 55 265 ep0 127.0.0.1 127.0.0.1 UH 2 6457 lo0 137.204.49/24 link#2 UC 0 0 ep0 137.204.49.17 0:20:af:b7:21:d9 UHLW 3 140397 lo0 137.204.49.30 0:60:8c:92:ae:a2 UHLW 0 10 ep0 1082 137.204.49.254 aa:0:4:0:1a:95 UHLW 56 0 ep0 428 my host is 137.204.49.17 the other 137.204.49.30 is a PC on the same lan and I do not know why it is in the routing table noone added it and it is not in rc scripts as a default route or alternative route path, so I do not understand can someone help me ?
