I resolved it, the problem was due to DNS and missing reverse entries for these hosts. Guess what, it was the logs in the syslog-ng that led to its own resolution !!! _____ From: syslog-ng-admin@lists.balabit.hu [mailto:syslog-ng-admin@lists.balabit.hu] On Behalf Of Badat, Qassim, ALABS Sent: Friday, May 14, 2004 11:58 AM To: syslog-ng@lists.balabit.hu Subject: [syslog-ng]cisco host not being resolved Hi, I am new to syslog-ng so excuse my ignorance. I have installed syslog-ng 1.6.2 on Solaris 8. I am getting the logs but the host names are not being resolved. . Strangely logs from another vendor's does have the names resolved by syslog-ng. Any idea whats causing the problem for cisco ? My syslog-ng.conf file: options { long_hostnames(off); sync(0); }; source sys { sun-streams ("/dev/log" door("/etc/.syslog_door")); internal(); }; source net { udp(); }; destination network { file("/var/log/syslog-ng"); }; log { source(net); destination(network); }; log { source(sys); destination(network); }; Regards, QB
