On ubuntu this file exists:
However the same file does not appear on CentOS Distributions. What is the equivalent file on CentOS?
Red Hat family distributions (including CentOS and Fedora) use
/var/log/secure where Debian-family distributions use
Note that in newer Fedora (or RHEL/CentOS 7 if someone has gone out of their way to configure it this way), you may have no traditional syslog daemon running. In that case, the same data can be shown with
journalctl (which defaults to producing text output in the syslog format).
In Red Hat Family distributions like CentOS and Fedora... instead of /etc/syslog.conf... it uses /etc/rsyslog.conf
