Hi, I installed ossec local on my cloud server, and configure ossec.conf as
follows, I tried to detect new additions using
<alert_new_files>yes</alert_new_files>.
<global>
<email_notification>yes</email_notification>
<email_to>my_em...@example.com</email_to>
<smtp_server>ns0.bt.net.</smtp_server>
<email_from>my_em...@example.com</email_from>
</global>
<syscheck>
<!-- Frequency that syscheck is executed - default to every 22 hours
-->
<frequency>79200</frequency>
<alert_new_files>yes</alert_new_files>
<!-- Directories to check (perform all possible verifications) -->
<directories report_changes="yes" realtime="yes"
check_all="yes">/etc,/usr/bin,/usr/sbin</directories>
<directories report_changes="yes" realtime="yes"
check_all="yes">/bin,/sbin</directories>
<directories report_changes="yes" realtime="yes"
check_all="yes">/home/user_name</directories>
</syscheck>
The local_rules.xml is like,
<group name="local,syslog,">
<!-- Note that rule id 5711 is defined at the ssh_rules file
- as a ssh failed login. This is just an example
- since ip 1.1.1.1 shouldn't be used anywhere.
- Level 0 means ignore.
-->
<rule id="100001" level="0">
<if_sid>5711</if_sid>
<srcip>1.1.1.1</srcip>
<description>Example of rule that will ignore sshd </description>
<description>failed logins from IP 1.1.1.1.</description>
</rule>
<rule id="554" level="7" overwrite="yes">
<category>ossec</category>
<decoded_as>syscheck_new_entry</decoded_as>
<description>File added to the system.</description>
<group>syscheck,</group>
</rule>
</group> <!-- SYSLOG,LOCAL -->
Now, if I added a file in home/user_name, there is no email notification
coming through the SMTP server. I am using smtp.bt.net, using
dig -t mx smtp.bt.net
to get the SMTP server. Whats the possible reasons that I am not getting
the email?
Many thanks
