something Posted August 14, 2002 Posted August 14, 2002 Hello, I am very new to linux. Last night I installed a copy of RedHat 7.3 on a dual P3 server. I selected "server" option during RH install, chose “no firewall” and let it install its bits and pieces. I then read the "Linux Server howto" thread in its entirety and followed the steps listed on how to get it up and running. What I would like to know is how do I check if people can access the server from the outside world? As I chose not to have a firewall (just while I’m checking it all) how can I double check if the specific ports are indeed unblocked? Any help or suggestions here would be greatly appreciated. Thanks.
something Posted August 14, 2002 Author Posted August 14, 2002 I've used a Port scanner to scan the port 28070 on my server and it says that it is blocked. What can I do to fix this?
NerfYoda Posted August 17, 2002 Posted August 17, 2002 your port scanner may only be checking TCP ports. In your console type in "netstat -a". This will show you which TCP & UDP ports are open on your server.
