[syslog-ng] Using usertty

[Gabor Nagy (gnagy)]

Hi Alex!

I've checked your attachments and I see that the messages are sent to pseudo-terminals and the serial port too:
[2020-10-23T16:40:20.647481] Posting message to user terminal; user='thanos', line='/dev/ttyS0'
[2020-10-23T16:40:20.647518] Posting message to user terminal; user='thanos', line='/dev/pts/0'
[2020-10-23T16:40:20.647530] Posting message to user terminal; user='thanos', line='/dev/pts/1'
[2020-10-23T16:40:20.647541] Posting message to user terminal; user='thanos', line='/dev/pts/2'

Can you check which terminals are the user 'thanos' logged in?
E.g. use the following command on the command line:
$w thanos

If you don't see a tty with ssh login, that can explain it.

About the serial port, maybe it's misconfigured.
Syslog-ng uses simple open/write calls on the device files , e.g. /dev/ttyS0. Can you try out if you can write in the /dev/ttyS0 file with a simple "echo test" command, please?
Can you tell us a bit more about your host and how did you set up the serial port?

Regards,
Gabor

Hi,
I am trying to use usertty(*) to send log all messages with severity equal or higher than critical to every user logged.

But I am not getting any messages in serial port or ssh.

I am sending the configurations and the debug log in attachment.

Can you help me to understand what is happening?

Thanks in advance,
Alex
