Hi all:
Thanks go to whoever fixed the bug in cygwin1.dll that caused syslog
to fail as soon as a udp packet was sent to it. The bug was introduced
sometime around 1.3.12, but is fixed now. So here is my recipe for
building syslog-ng-1.5.24.
Download syslog-ng-1.5.24 and libol-0.3.6. Patch the syslog source
with the patch at the end of this message. The patch adds a -N flag to
stop the syslog server from forking so that windows services mechanism
and cygrunsrv will properly detect that the program/service is
running. The man page is updated with this flag, but the html/sgml
isn't patched. The patch also stops resolv.h from being included
under __CYGWIN__, and defined the typdef uint32_t as unsigned.
After applying the patch, touch src/main.c.x src/filter.c.x, then
configure and make the two packages. Then run cygrunsrv as:
cygrunsrv -I syslog -a '-N' -p /path/to/syslog -c /var/log
and
cygrunsrv -S syslog
I use the syslog server with backlog to send the event log on my
windows 2000 SP3 system to a file. I did most of my testing without
tcp wrappers enabled, but I did finally get it to compile with the
wrappers. To do this, change the lines that read:
old_LDFLAGS=$LDFLAGS
LDFLAGS=-lwrap
to read
old_LIBS=$LIBS
LIBS=-lwrap
and you will get
checking for hosts_access in -lwrap... yes
rather than
checking for hosts_access in -lwrap... no
Hopefully the syslog-ng people will include this patch in newer
versions.
