Contact an ICE server with Java on a Linux server

bokang

I am inquiring about running an ICE server implemented in Java.
When running in Windows with the same source and classpath, the server starts up without any problems.
Running on a Linux server will result in the following error:

I can not confirm the error, so I will contact you.

Hi,

You've enabled the syslog logger but your Linux syslog daemon doesn't accept remote connections. You should either disable this logger (by setting Ice.UseSyslog=0) or change the syslog daemon configuration to accept connections. Since you also set Ice.LogFile, I suppose you want the logging to go to a file in which case you shouldn't set Ice.UseSyslog (or set it to 0).

Cheers,
Benoit.
