Re: [syslog-ng] Problem sending logs to central log server..

In your server config, the only listener you have on udp port 514 is defined in src_eventdb, and all src_eventdb entries are commented out. -Patrick Sent: Mon Sep 19 2011 11:40:15 GMT-0600 (MST) From: rek2 <rek2gnulinux@gmail.com> To: syslog-ng@lists.balabit.hu Subject: [syslog-ng] Problem sending logs to central log server..

Hello, I'm trying to sent all my logs from one openbsd server with syslog-ng to a linux ubuntu central log server also with syslog-ng of course but only the syslog-ng logs are been logged.. also when I do a "logger test" for example it gets log locally but not remotely to the log server... here are my configs:

for the log server is basically the defaul of ubuntu with my addtions at the end.. you will see some commented is me trying to fix this issue.

cat syslog-ng/syslog-ng.conf # # Configuration file for syslog-ng under Debian # # attempts at reproducing default syslog behavior

# the standard syslog levels are (in descending order of priority): # emerg alert crit err warning notice info debug # the aliases "error", "panic", and "warn" are deprecated # the "none" priority found in the original syslogd configuration is # only used in internal messages created by syslogd

###### # options

options { # disable the chained hostname format in logs # (default is enabled) chain_hostnames(0);

# the time to wait before a died connection is re-established # (default is 60) time_reopen(10);

# the time to wait before an idle destination file is closed # (default is 60) time_reap(360);

# the number of lines buffered before written to file # you might want to increase this if your disk isn't catching with # all the log messages you get or if you want less disk activity # (say on a laptop) # (default is 0) #sync(0);

# the number of lines fitting in the output queue log_fifo_size(2048);

# enable or disable directory creation for destination files create_dirs(yes);

# default owner, group, and permissions for log files # (defaults are 0, 0, 0600) #owner(root); group(adm); perm(0640);

# default owner, group, and permissions for created directories # (defaults are 0, 0, 0700) #dir_owner(root); #dir_group(root); dir_perm(0755);

# enable or disable DNS usage # syslog-ng blocks on DNS queries, so enabling DNS may lead to # a Denial of Service attack # (default is yes) use_dns(yes);

# maximum length of message in bytes # this is only limited by the program listening on the /dev/log Unix # socket, glibc can handle arbitrary length log messages, but -- for # example -- syslogd accepts only 1024 bytes # (default is 2048) #log_msg_size(2048);

#Disable statistic log messages. stats_freq(0);

# Some program send log messages through a private implementation. # and sometimes that implementation is bad. If this happen syslog-ng # may recognise the program name as hostname. Whit this option # we tell the syslog-ng that if a hostname match this regexp than that # is not a real hostname. bad_hostname("^gconfd$"); keep_hostname (yes);
