<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body text="#000000" bgcolor="#FFFFFF"> Hi, If I understand correctly, this mailing list can be used for questions about udev as well as about systemd. If that's not correct, somebody please let me know and I will go elsewhere (and if you know where that "elsewhere" should be, please let me know, that would be helpful!); I don't mean to use the list incorrectly. I want to call a webhook inside a script run via a RUN directive in a udev rule. When I try to do this, curl says it's unable to resolve the host name of the URL I am asking it to fetch. To collect more data about the cause of this issue, I also tried doing a "ping -c 1 8.8.8.8" inside the script, and it gets, "sendmsg: Operation not permitted." I assume this means udev scripts are running inside some sort of restricted environment or something, but I can't figure out what controls the restrictions on that environment, whether I can loosen them, or how. I'm on Ubuntu 18.04. Any advice? Thank you, Jonathan Kamens </body> </html>
