→ Applies to: SynetoOS 4.x


These are the services used for alert notifications:

svc:/network/sendmail-client:default
svc:/network/smtp:sendmail

 

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

 

Step 2 (optional). Change into Solaris shell (in case you're directed to an unsupported shell)

un sh

 

Step 3. Get root privileges

sudo su -

 

Step 4. Check logs on messages file

cat /var/log/messages | grep sendmail


Step 5. Check the service file logs

cat /var/svc/log/network-sendmail-client:default.log
cat /var/svc/log/network-smtp:sendmail.log
cat /var/svc/log/system-fm-smtp-notify:default.log

 

Step 6. Check the first line for the address used to send email notifications

cat /var/storage/mail_sender_address.conf 

 

Step 7. Check the .ini file that contains the current SMTP configuration as indicated in the GUI

cat /var/storage/mailer.ini

EXAMPLE OUTPUT

cat /var/storage/mailer.ini
transport = smtp
host = smtp.gmail.com
port = 25
ssl = 0
auth = 0
username = synetotestalert@domain.com
password = passexample
sender = synetotestalert@domain.com
