Screenshot possibly opens networking or network storage location
Closed, ResolvedPublic


On a coffee-shop/hotel WiFi opening GNOME Screenshot repeatedly pops up intercepted networking certificate alert.

Reproduction Steps:

  1. have a network connection that requires web authentication
  2. have a cloud storage location for calendar/files/etc (normal nextcloud setup)
  3. open Screenshot
  4. see security alert appear

Expected result:
That Screenshot would not require network access to simple execute/run/open up.

Looking at GNOME's Screenshot with Strace I don't see a call to external networking resources. Running this command;

strace -e trace=%network -e connect /usr/bin/gnome-screenshot


connect(5, {sa_family=AF_UNIX, sun_path="/run/user/1000/bus"}, 110) = 0
connect(7, {sa_family=AF_UNIX, sun_path="/run/user/1000/wayland-0"}, 27) = 0
connect(10, {sa_family=AF_UNIX, sun_path="/run/user/1000/bus"}, 20) = 0
connect(11, {sa_family=AF_UNIX, sun_path=@"/tmp/dbus-dKaYsqlE1q"}, 23) = 0
connect(16, {sa_family=AF_UNIX, sun_path="/run/user/1000/pulse/native"}, 110) = 0

I'm not on the same network you're on and I don't know if you have changed the settings of GNOME screen shot in anyway so you may get different results. But it doesn't look like GNOME screenshot is using network for anything other that local dbus communication.
