Hello,
I am using syslog-ng 1.5.14. I am trying to get the log messages to display the full hostname instead of the short name.
For instance,
Feb 4 10:06:42 mailhost su: 'su toto' succeeded for ylau on /dev/pts/0
We have several servers with the name "mailhost" so I would like it to show mailhost.nyc1.globix.net so I can tell which one it is.
Here are the options I have set:
options { sync (0); time_reopen (10); log_fifo_size (1000); create_dirs (yes); chain_hostnames (no); use_dns (no); use_fqdn (yes); };
Where is it picking up the short name and how can I get it to show the full name? Sometimes the log shows IP addresses, that is OK.
hmm. if keep_hostname is true, it should not touch the hostname, if it is false, the hostname should always be rewritten. if (!self->keep_hostname || !logmsg->host) { ... rewrite host ... } Thus, if keep_hostname() is false (default), the hostname is always rewritten. Ops, I think I have the problem. get_source_hostname() function in sources.c: if (... received from network ...) { ... resolve source ip, chomp domain if use_fqdn is false ... } else { ... this message is local ... getshorthostname(), even if use_fqdn() is true. } thus the hostname you are picking up comes from a local message.
