Title: Script cannot access network when triggered by udev rule Status in systemd package in Ubuntu: New Bug description: I have a script that is triggered by a udev rule, and that needs to connect to a remote host. The example below works fine in 16.04, but fails in 18.04. It seems that the process executing the script is somehow limited wrt. network access. The script works fine when started from a shell prompt. To reproduce: - create /tmp/myscript: #/bin/sh wget -o /tmp/wget.log -O /tmp/index.html http://www.google.com - create /etc/udev/rules.d/52-netaccess.rules ACTION=="add", ATTRS{idVendor}=="cafe", MODE="0660", GROUP="root", SUBSYSTEM=="usbmisc", RUN+="/tmp/myscript" - Plugin a USB device with vendor ID 0xcafe, and check the wget output in /tmp/wget.log. On ubuntu 18.04 wget fails with this output: --2019-08-19 14:49:43-- http://www.google.com/ Resolving www.google.com (www.google.com)... failed: Name or service not known. wget: unable to resolve host address 'www.google.com' If I use an IP address in the URL there is no resolve error, but then wget blocks in the socket connect() syscall (according to strace). At some point the script is killed.
