[-- Attachment #1 --] Hello to all, Today I've run nmap to scan my server ports and I found a port that I don't know (Well Known Ports: 0 to 1023) [nmap] 1023/tcp open unknown I login at the server I there it is again and netstat shows: [netstat -n] tcp4 0 0 *.1023 *.* LISTEN Could my server be in security problems? What service or program open this port and how do I turn it off? Thanks very much, Nuno Teixeira [-- Attachment #2 --] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=iso-8859-1"> <META content="MSHTML 5.50.4522.1800" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV><FONT face=Arial size=2>Hello to all,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Today I've run nmap to scan my server ports and I found a port that I don't know (Well Known Ports: 0 to 1023)</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>[nmap]</FONT></DIV> <DIV><FONT face=Arial size=2>1023/tcp open unknown</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>I login at the server I there it is again and netstat shows:</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>[netstat -n]</FONT></DIV> <DIV><FONT face=Arial size=2>tcp4 0 0 *.1023 *.* LISTEN</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Could my server be in security problems?</FONT></DIV> <DIV><FONT face=Arial size=2>What service or program open this port and how do I turn it off?</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV> </DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Thanks very much,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Nuno Teixeira</FONT></DIV></BODY></HTML>
