When I issue $ ping google.com on the terminal, the command doesn’t do anything. When I Ctrl+c out of it, it reports 100 percent packet loss.
I have tried this command on:
a DispVM based on debian-11-dvm
a debian-11-minimal based qube
my sys-net qube (which is a debian-11-minimal based qube, as set up by following the minimal templates qubes-os documentation)
I am having this problem on a cafe public wifi.
I am able to connect to the internet just fine, apart from this ping-problem. My sys-net network manager reports that it is connected to the cafe’s wifi network. The sys-whonix has synced its sdwdate stuff. I am on tor browser, writing this post on qubes-os forum. My clearnet web browser is able to browse websites—all is fine but the ping command…
I do not understand this. Can someone help me understand?
In short, it’s the protocol used to send ping and conduct diagnostics on a network. Since it’s not needed for daily activities (browsing, emails, etc…), which instead use TCP and UDP, network administrators may choose to block ICMP requests to prevent, for example, some network scans or other exploits of the ICMP protocol.
