That's a lot! This clearly explains what's going on. I've tried simple python example from https://docs.python.org/2/library/syslog.html#syslog.openlog which is a wrapper around openlog/closelog/syslog(3) calls. And bingo, I see messages in EventLog. I'm surprised that current logger implementation uses /dev/log or network socket only, and there is no way to ask it to use openlog/closelog/syslog(3) calls. However in the man page it tells that it used them back in days.That's sad. I've tried to play with --socket-errors= logger option also. No luck. As workaround I could write logger in python/perl/any_lang that uses openlog/closelog/syslog(3) calls, name it logger and place somewhere earlier in PATH > You should ensure that /dev/log does not exist as a regular file, as that could > affect logging: > $ ls -lF /dev/log > If not a socket (= flag), check the contents for your logging tests. > Then delete /dev/log, and retest. > > You may need to run something like: > https://www.codeproject.com/Articles/18086/Syslog-daemon-for-Windows-Eventlog > to put syslog messages into the Windows Event Log. > > -- > Take care.
