Syntax error when using the tcp-keep-alive() option
Hi there, I'm working on using syslog-ng within our environment mainly due to the ability to use syslog with tcp. I will be traversing firewalls and therefore the tcp-keep-alive() option is vital for me. However when I try to turn this on in my tcp source it gives me a syntax error. I have pasted in the relevant part of the config below. I'm pretty sure I have it right. The strange thing is that when I search the source code for the option I can't find anything as if it has been removed from version 2.0 (the version I'm using). Does anyone know what may have happened to the tcp-keep-alive option in version 2.0 and, if I'm right and it isn't there, what are the options in syslog-ng that I could use to prevent the sessions timing out on firewalls? source testsrc { tcp( ip(0.0.0.0) port(5514) max-connections(300) keep-alive(yes) tcp-keep-alive(yes) ); }; Thanks.

As syslog-ng 2.0 was forked earlier than tcp-keep-alive option was added, this missing keyword was missed. I've now committed an implementation of a so_keepalive option (renamed for consistency), but an obsolete tcp-keep-alive() keyword was also added for compatibility. It should be available in tomorrow's snapshot. -- Bazsi
