Did you run the -config scripts to setup the services? Did you restart all services after any changes? # for srv in cygserver syslog-ng cron; do \ for o in -Q -E -Q -S -Q; do \ cygrunsrv $o $srv; done; done Check /dev/log: # ls -lF --color /dev/log srw-rw-rw- 1 SYSTEM SYSTEM 0 Jul 10 12:28 /dev/log= if you don't see a pink /dev/log with "=" flag, and it's just black with no "=" flag, rm /dev/log and restart syslog-ng as above. Do not forget to *ALWAYS* shut down all Cygwin services before running setup to upgrade any Cygwin packages. You can check the status of all services with a command such as $ cygrunsrv -VL | sed -Ee '/^Service\s*:\s*/{s// /;s/\s+$//;s/\s*(\S+)\s+$Installation\spath\s*:\s*.*$$/ (\1)/;H;};/^Current\sState\s*:\s*/{s// /;s/\s*$/ /;H;};$!d;${x;s/\n|\s+$|^\s+//g;}' cron Running cygserver Running syslog-ng Running -- Take care.
