Hi all Iâm integrating the SysLogSender of Goran as an extension of SystemLogger and my system gets blocked when I try to send something. I just did the same as in the original version (and know nothing about upd and port). I suspect that on mac is not working the same. https://developer.apple.com/library/mac/documentation/macosx/conceptual/bpsy... Does any of you have some ideas? my code look like that: | logger | logger := SysLogSender new addHost: 'localhost' port: 514. Log dispatcher addLogger: logger. Log dispatcher startAllLoggers. send: message to: host port: port "Send formatted UDP message to host and port." | sock | sock := Socket newUDP. sock setPeer: NetNameResolver localHostAddress port: port. sock sendData: message. sock waitForSendDoneFor: Socket standardTimeout. sock close Stef
