Hello Yup, I realized that. I thought it was supposed to be the ip of the client. So I am using filters to cater for the different clients..only issue is I will end up with lots of filtering.. Do you have any example for logging firewall logs..

Let's see an example: addresses of your server are the following (in this example your server has two network cards): 192.168.20.1 (eth0) 10.30.20.1 (eth1) 127.0.0.1 (loopback) source apache_access{tcp(ip("192.168.20.1") flags(no-parse)); }; syslog-ng will listen only on eth0:192.168.20.1 source apache_access{tcp(ip("10.30.20.1") flags(no-parse)); }; syslog-ng will listen only on eth1:10.30.20.1 source apache_access{tcp(flags(no-parse)); }; syslog-ng will listen on all addresses of your server (eth0:192.168.20.1, eth1:10.30.20.1, lo:127.0.0.1) source apache_access{tcp(ip("10.10.0.1") flags(no-parse)); }; syslog-ng cannot listen on this address, because it's not an address of the server, you will receive "Cannot assign requested address" error message. If you have no specieal reasons to limit it, just don't give "ip()" option because it is not required (as Patrick wrote) 2010.07.19. 8:14 keltezéssel, Khaleelah Peerbocus írta: Still if I wanted to configure a different source on the syslog-server as below (I will eventually use filtering if I do not succeed in creating another source) source apache_access{tcp(ip("192.168.180.179") flags(no-parse)); }; destination d_apachemssql { pipe("/tmp/apachepipe.pipe" template("INSERT INTO logapache(datetime,host,program,pid,message)VALUES('$R_DATE','$HOST','$PROGR AM','$PID','$MSGONLY');\n")template-escape(yes) flags(no-multi-line)); }; log { source(apache_access); destination(d_apachemssql); }; I get the following error when trying to start syslog-ng Error binding socket; addr='AF_INET(192.168.180.179:3331)', error='Cannot assign requested address (99)' Error initializing source driver; source='apache_access', id='apache_access#0' Error initializing message pipeline; From: syslog-ng-bounces@lists.balabit.hu [mailto:syslog-ng-bounces@lists.balabit.hu] On Behalf Of Patrick H.

It specifies the IP address which syslog-ng will listen on. If not provided, syslog-ng will listen on all interfaces. Seconly, you do not need a separate source for every client. You can use filter rules to match on the client's hostname if you need to. You might want to go through the administrator's guide, it is an extremely good documentation source with lots of examples. http://www.balabit.com/dl/guides/syslog-ng-ose-v3.1-guide-admin-en.pdf Sent: Sunday, July 18, 2010 11:28:25 PM From: Khaleelah Peerbocus <mailto:systems2@maccs.mu> <systems2@maccs.mu> To: 'Syslog-ng users' and developers' mailing list' <mailto:syslog-ng@lists.balabit.hu> <syslog-ng@lists.balabit.hu> Subject: [syslog-ng] configuring different sources on the syslog-ng server Hello I would like to get some clarification on the source tag in both syslog client and server. I have different clients hosting apache / weblogic My Syslog-ng Server has ip 192.x.x.x Apache (client) has ip 192.x.x.1 Weblogic (client) has ip 192.x.x.2 In all the clients syslog configuration files, i have added destination apacheaccesslog { tcp("192.x.x.x " port(3331)); }; destination weblogiclog { tcp("192.x.x.x " port(3332)); }; My issue is in the syslog-ng server configuration file, if i add source apache_access {tcp(ip(192.x.x.x) port(3331)); }; Should the ip be the server ip or the client ip (in this example, i have put the syslog-ng server ip). Does the port number differentiate the different sources we are receiving the log files ??? logo-emailsignature.jpgKhaleelah Peerbocus Systems Analyst Mauritius Cargo Community Services Business Registration No.: C08077158 VAT Registration No.: VAT20427044 1st Floor, Trade and Marketing Centre, Mer Rouge Port-Louis, Mauritius Tel: +230 206 2970 - Cell: +230 498 7897 Fax: +230 216 8858 Email: <mailto:HDagent6@maccs.mu> systems2@maccs.mu - Website: <http://www.maccs.mu/> http://www.maccs.mu _____ ____________________________________________________________________________ __ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.campin.net/syslog-ng/faq.html ____________________________________________________________________________ __ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.campin.net/syslog-ng/faq.html -- pzolee
