Comment 2 for bug 1957792

iputils was updated in centOS 8 stream:

iputils-20180629-8.e..> 2022-01-10 15:06 148K

vs
iputils-20180629-7.e..> 2021-02-24 04:41 148K

Noted change:
2022-01-03 - Jan Macku <email address hidden> - 20180629-8 - Make ping unprivileged (#2030107)

The multinode-ipa job has two node - an undercloud and an ipa (secondary node).

On the undercloud node:

[zuul@node-0001959385 ~]$ rpm -qa | grep iputils
iputils-20180629-7.el8.x86_64

[zuul@node-0001959385 ~]$ ping redhat.com
PING redhat.com (209.132.183.105) 56(84) bytes of data.
64 bytes from redirect.redhat.com (209.132.183.105): icmp_seq=1 ttl=237 time=67.1 m

On the ipa node:

[zuul@ipa ~]$ rpm -qa | grep iputils
iputils-20180629-8.el8.x86_64

[zuul@ipa ~]$ ping redhat.com
ping: socket: Operation not permitted

So the ipa node must update and get the newer version.

Testing the downgrade:

[zuul@ipa ~]$ sudo dnf downgrade iputils-20180629-7.el8.x86_64
