Description of problem:
SELinux is preventing ssh-keygen from 'open' accesses on the plik /etc/passwd.

*****  Plugin catchall (100. confidence) suggests   **************************

Aby ssh-keygen powinno mieć domyślnie open dostęp do passwd file.
Then proszę to zgłosić jako błąd.
Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp.
Do
można tymczasowo zezwolić na ten dostęp wykonując polecenia:
# ausearch -c 'ssh-keygen' --raw | audit2allow -M my-sshkeygen
# semodule -X 300 -i my-sshkeygen.pp
