It appears that syslog-ng has an issue on OpenBSD/sparc64, as it does not determine the hostname of the remote system, making all messages appear to be from the syslog-ng server. The bug appears to be well hidden in sources.c. In line 98, the call to do_recv (as seen in gdb backtrace) is made, which requires a socklen_t* parameter. The catch is in line 88, where salen is declared as size_t and then cast to socklen_t; on sparc64, size_t is 64bit and socklen_t is 32bit and that causes the salen variable to always contain 0, causing the known bug. If you change line 88 to socklen_t salen = sizeof(sabuf), the host name of the sending host is determined correctly and written in the logfiles. That also explains why syslog-ng works correctly on OpenBSD/i386, but not on sparc64. Bostjan Golob IT department, Gimnazija Bezigrad, Ljubljana, SI
