Description
Because hostname and timezone are both string types, they are being confused by the parser, even though timezone parsing should throw an exception if an invalid value (such as a hostname) is encountered.
If you observe here even though hostname is localhost it’s not considered as hostname since it was parsed as timezone and exception was thrown and further it has got parsed:
<14> Nov 16 00:01:25 localhost postfix/smtpd[1713]: connect from www.opennms.org[10.1.1.1] true UEI : uei.opennms.org/syslogd/user/Info Time : Wed Nov 16 00:01:25 IST 2016 NodeId : 0 Ip Address : null Host Name : null Log Message : connect from www.opennms.org[10.1.1.1] Syslog Message : connect from www.opennms.org[10.1.1.1] Nov 15 18:31:25 Facility : user Priority : Info
This is parsed correctly:
<19> Nov 17 14:28:48 CST %AUTHPRIV-3-SYSTEM_MSG[0]: Authentication failed from 10.10.10.10 - sshd[20189] true UEI : uei.opennms.org/syslogd/mail/Error Time : Thu Nov 17 14:28:48 IST 2016 NodeId : 0 Ip Address : null Host Name : null Log Message : Authentication failed from 10.10.10.10 - sshd[20189] Syslog Message : Authentication failed from 10.10.10.10 - sshd[20189] Nov 17 08:58:48 Facility : mail Priority : Error
If we keep hostname first and time zone we can see following, hostname is parsed correctly:
<14> Nov 16 00:01:25 localhost postfix/smtpd[1713]: connect from www.opennms.org[10.1.1.1] true UEI : uei.opennms.org/syslogd/user/Info Time : Wed Nov 16 00:01:25 IST 2016 NodeId : 0 Ip Address : 127.0.0.1 Host Name : localhost Log Message : connect from www.opennms.org[10.1.1.1] Syslog Message : connect from www.opennms.org[10.1.1.1] Nov 15 18:31:25 Facility : user Priority : Info Process : postfix/smtpd Processid : 1713
But here time zone is considered as hostname:
<19> Nov 17 14:28:48 CST %AUTHPRIV-3-SYSTEM_MSG[0]: Authentication failed from 10.10.10.10 - sshd[20189] true UEI : uei.opennms.org/syslogd/mail/Error Time : Thu Nov 17 14:28:48 IST 2016 NodeId : 0 Ip Address : 10.10.2.2 Host Name : CST Log Message : Authentication failed from 10.10.10.10 - sshd[20189] Syslog Message : Authentication failed from 10.10.10.10 - sshd[20189] Nov 17 08:58:48 Facility : mail Priority : Error Process : %AUTHPRIV-3-SYSTEM_MSG Processid : 0
