Hi all! I have just run netstat -na and I have noticed that I have port 18300 (tcp) open. I have run fuser as root, but without output. What is this port? Any Idea? A trojan? I am wondering what is it port 1 (raw). Please tell me something about that too. Here it is the output of netstat -na: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:901 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:139 0.0.0.0:* LISTEN tcp 0 0 192.168.0.3:139 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:7741 0.0.0.0:* LISTEN tcp 0 0 192.168.0.3:6000 192.168.0.1:2813 ESTABLISHED tcp 0 0 192.168.0.3:6000 192.168.0.1:1025 ESTABLISHED tcp 0 0 192.168.0.3:1333 192.168.0.1:139 ESTABLISHED tcp 0 0 192.168.0.3:1022 212.171.48.156:22 ESTABLISHED tcp 0 0 192.168.0.3:1023 192.168.0.1:22 ESTABLISHED tcp 0 0 :::18300 :::* LISTEN udp 0 0 192.168.0.3:137 0.0.0.0:* udp 0 0 0.0.0.0:137 0.0.0.0:* udp 0 0 192.168.0.3:138 0.0.0.0:* udp 0 0 0.0.0.0:138 0.0.0.0:* udp 0 0 0.0.0.0:7741 0.0.0.0:* raw 0 0 0.0.0.0:1 0.0.0.0:* port 7741 is lisa.
