ping fails with "Operation not permitted"

[ChrisArena52]

When I do a ping, I get this error:

cubie@cubieboard:~$ ping www.google.com
ping: icmp open socket: Operation not permitted

There is a discussion of this elsewhere: https://discuss.zendesk.com/hc/en-us/articles/202374517-Linux-ping-command-fails-with-icmp-open-socket-Operation-not-permitted-

Doing the following fixes things:

root@cubieboard:/bin# chmod 4755 ping
root@cubieboard:/bin# ls -tlr ping
-rwsr-xr-x 1 root root 34752 Nov  8  2014 ping

Then ping works:

cubie@cubieboard:~$ ping www.google.com

Can ping be given the correct permission so that this maneuver isn't required?

 

Thanks,

Debian related bug?

I'll put an adjustment into rc.local ....

had the same problem here,

setcap cap_net_raw+ep /bin/ping

executed as root, solved it, remains ok after boot.
