I have below two tcpdump, Want to know what are "syslog.info" and "local6.info" column meaning? and what are the representation of syslog.info and local6.info
06:56:07.533143 IP 10.10.40.10.52126 > 10.18.40.58.514: SYSLOG **syslog.info**, length: 189
06:56:07.669902 IP 10.10.40.15.37866 > 10.18.40.58.514: SYSLOG **local6.info**, length: 292
void openlog(const char *ident, int option, int facility); where priority is facility | level. In the string version above facility syslog and local6 corresponds to LOG_SYSLOG and LOG_LOCAL6, and info is the level which corresponds to LOG_INFO. As for semantic:
LOG_SYSLOG: messages generated internally by syslogd(8)
LOG_USER (default): generic user-level messages
LOG_INFO: informational message
