Hi everybody,

I have no idea how I got in this mess, but I've lost the ability to use
ping as a regular user.  sudo still works.

What do you get with:
sysctl net.ipv4.ping_group_range


For me:
sysctl net.ipv4.ping_group_range
net.ipv4.ping_group_range = 0   2147483647

Thanks everybody who replied.

OK, I've been doing a lot of network experiments, staying up waaaay too late, and I have no recollection of doing this. It was set to:

> net.ipv4.ping_group_range = 1      0

Changing as recommended and I'm back in business...
