If you have to enter a password in your operating system, you’re more secure. dms.spb / How to Tell If You’re Vulnerable to Snooping This means your traffic can be snooped on. The router allows you to access the Internet, but it doesn’t actually encrypt the network-it’s still open. However, after you authenticate, you’re still using an open Wi-Fi network. RELATED: How to Share a Hotel's Single Wi-Fi Connection With All Your Devices It also allows the hotel to limit the number of devices that can access the Internet-but you can share that single hotel Wi-Fi connection with multiple devices. In a sense, you are-the hotel’s “captive portal” prevents you from accessing the Internet until you authenticate yourself. If you connect to an open Wi-Fi network and then see a page with information about the hotel and have to enter a room number or another password to connect, you may think you’re connected to a secure network. Thanks in advance for any pointers.Captive Portals Only Limit Access to the Internet I guess my confusion right now is how to write a Windows script that will run the pings and provide an output to NSClient++ to hand off to Nagios. If someone can point me toward some links that explain what I'm trying to do I believe that I can figure it out by reverse engineering and understanding the commands. I've got years of experience at Layer 3 and below but am really new to programming (Windows and Linux). The vast majority of my VPNs allow ping from Host A to Host B so having my Host continuously ping their Host and report to my Nagios server via passive_checks should do what I want. I would have to contact each vendor and negotiate with them the addition of my Nagios Server ip address to their vpn tunnel. I cannot ping across the vpn from my Nagios server because it is not defined in the vpn routing/policy. Generally speaking, this means that the allowed traffic is from Host A (/32) to Host B (/32) since neither party wants to expose any more of their network than necessary. The allowed tunnel traffic is defined by the routing/policies of the associated vpn devices. These are site-to-site IPSEC VPNs where the tunnels are built from vpn concentrator to vpn concentrator (firewall to firewall) over the Internet. After searching the documentation available all I can say is My Brain Hurts! Confusion reigns supreme!Ĭan anyone out there point me in the correct direction and help cut through the noise? What I'd like to do is run a batch program or script on my local Windows servers that pings the vpn associated remote hosts and use passive checks from the local server to monitor the vpn state. I also cannot install anything on the remote vendor servers. I can't do a host alive check from my Nagios server because it isn't defined as a host in any of the vpns and I cannot add it to the vpns. These are all Windows to Windows host vpns. We have 50+ vpns to other vendors with various remote vpn terminating equipment so the vpn state monitoring varies vpn to vpn. Now my boss wants to be able to monitor the host to host connectivity through our network of vpns. I have managed to install the Nagios server and successfully monitor 60+ Windows servers for disk space, etc. Please be patient with me as I am a noobie to Linux and Nagios.
