I was hosting a site there, but the administration is unresponsive and I gave up on them. Lovely place, though.
replyIt’s great when you want to check on a server or IP from an outside network. You can do that from a phone but with SDF you have your full desktop terminal if you like and a clean cache.
replyThey allow port scans?
replyI did use nmap on a Linux VM going over the free ProtonVPN for this purpose, but at some point Proton broke something (it may be related to their VPN accelerator feature) and checking any port always reports "Open" (even if it's not), so sadly that made this cool use case entirely useless for me. It definitely was nice to know you had no open ports other than the ones you purposefully opened. :)
