I installed the globalping-probe yesterday on my TrueNAS system. Here is the version information:
- Name: globalping-probe
- App Version: 0.41.4
- Version: 1.0.1
- TrueNAS 25.10.0.1 - Goldeye
I set up my probe, but apparently, I’m not able to ping out:
Looking at the log files from https://dash.globalping.io/ , I see this:

Okay, so the information is reaching the external website, but not the pings. Checking at the TrueNAS server level:

So far, so good. Checking at the Docker level:
$ ping a.gtld-servers.net
ping: socktype: SOCK_RAW
ping: socket: Operation not permitted
ping: => missing cap_net_raw+p capability or setuid?
$ ping k.root-servers.net
ping: socktype: SOCK_RAW
ping: socket: Operation not permitted
ping: => missing cap_net_raw+p capability or setuid?
$ ping time.apple.com
ping: socktype: SOCK_RAW
ping: socket: Operation not permitted
ping: => missing cap_net_raw+p capability or setuid?
Okay, but does DNS resolve at the Docker level?
$ nslookup a.gtld-servers.net
Server: 208.67.222.222
Address: 208.67.222.222#53
Non-authoritative answer:
Name: a.gtld-servers.net
Address: 192.5.6.30
Name: a.gtld-servers.net
Address: 2001:503:a83e::2:30
Unfortunately, ifconfig and ip addr are unknown commands.
$ ifconfig
/bin/sh: 7: ifconfig: not found
$ ip addr
/bin/sh: 8: ip: not found
My TrueNAS Docker configuration is as follows:
What am I missing here?
