Zabbix 5.0 on Ubuntu 20.04

[RSA]

After install and start Zabbiz-sever i have some problem with ping hosts in zabbix web:
ping from server

root@Zabbix:/home/rsa# ping 10.17.111.249
PING 10.17.111.249 (10.17.111.249) 56(84) bytes of data.
64 bytes from 10.17.111.249: icmp_seq=1 ttl=62 time=3.73 ms
64 bytes from 10.17.111.249: icmp_seq=2 ttl=62 time=3.20 ms

ping from web:

• ping -c 3 10.17.111.249; case $? in [01]) true;; *) false;; esac

You ran the command line test as root. On most Linux systems, 'root' has no restrictions and can do things a normal account can't.

The Zabbix web interface runs as a non-privileged user. That's good, and it's what you want, but it means that some commands or operations will be restricted.

The "socket: Operation not permitted" likely means that "ping" is restricted. Different distros treat the "should a nonprivileged account be able to run ping?" question differently, so it may be that there's something specific to Ubuntu that needs to be configured or set, to make ping available to the web user. It might be using the "setcap" command, to add the appropriate network capabilities(7) to the ping command, or it might be adding the web user's "group" to some sysctl config file, to indicate that the web user is allowed to use the ping command. If you find documentation recommending you just make "ping" set-uid root, that's probably outdated, and these days I would continue looking to see if there's some other recommendation for your particular distro to make ping available to a normal user account.
