Just a little while ago I checked my kuma status page and noted that several checks were failing. In troubleshooting, I found that at least the ping command had a problem.
ping www.google.com ping: socket: Operation not permitted
Needless to say, this became rather annoying and off to google I went. I quickly found these two pages that described the problem and a fix for it. While I don’t understand yet how the problem started on my system, I am glad I found a fix.
