Here's what my config looks like now, after the second variant:<br>

@version: 3.30<br>
<br>
@include "scl.conf"<br>
<br>
options {<br>
threaded(yes);<br>
chain_hostnames(no);<br>
stats_freq(43200);<br>
mark_freq(3600);<br>
};<br>
<br>
source src { system(); internal(); };<br>
<br>
filter samba { program("samba"); };<br>
filter ssh_messages { facility("AUTH") and level("INFO"); };<br>
filter syslog { not filter("ssh_messages") and not filter("samba"); };<br>
<br>
destination console { file("/dev/tty12"); };<br>
destination messages { file("/var/log/messages"); };<br>
destination sshd_log { file("/var/log/sshd/sshd.log"); };<br>
destination smb_logs { file("/var/log/samba/samba.log"); };<br>
<br>
log { source(src); filter(samba); destination(smb_logs); flags(final); );<br>
log { source(src); filter(ssh_messages); destination(sshd_log); <br>
flags(final); };<br>
log { source(src); filter(syslog); destination(console); };<br>
log { source(src); filter(syslog); destination(messages); };<br>
<br>
<br>
Still, sshd messages are appearing in /var/log/messages.<br>
