If you got a 404 message, that tells me that maybe a personal webserver is running on that port and you just don't have any pages for it to serve. you may be able to go into Composer and turn this off. Sounds like a security risk to me in any event. Brian Kelsay >>> J C 06/03/04 05:07AM >>> I seem to be having an issue with netscape navigator 7.1. I don't use Netscape hardly but it came with the ditro I'm using, Slackware 9.1. I run nmap on my network quite often. What I have found is that everytime Netscape is running port 5180 is open. Nmap does not give any info regarding the port and says it's unknown. I tried to establish a connection with port 5180 and I recived a 404 error like some sort of web service is running on it. Does anyone know anything regarding Netscape and that particular port? Thanks.
