Cacti 1.1.36 mail sending error

[kgujas]

Hi, i have cacti 1.1.36 on ubuntu 16.04 , and I still have the problem with mail sending ... with TLS , SSL or no security I always getting this error , SMTP connect() failed.

Anyone else have this issue ? Please help me, what to do first ...

Have you try to change metod to sendmail? it work? I don't have problem with my cacti server.

[netniV]

What are your settings for sending mail? Are you using SendMail, SMTP, etc?

[cigamit]

We should automatically changes the ports when someone changes the encryption from None to TLS or SSL.

[netniV]

I have thought that in the past. Should put it on the action list even if there's no response for this issue.

The only way I can get SMTP to work on my systems is to disable openssl from php.ini. I can select no security and it will still try and to an ssl handshake (seen in Wireshark) no matter what I set it to.

[kgujas]

My config is , php 7.0.25 , mariadb 10.0.34 .... email sending not working with smtp ( with ssl,tls , no security , port 25,465,587 , with or without authentication ) with sendmail i got this error , Sending Message... Could not execute: /usr/sbin/sendmail -t

with the same SMTP setting my old cacti 0.8.8 works OK.

[kgujas]

in my php.ini openssl is like this ;extension=php_openssl.dll

[andermat8]

@kgujas, it's in there twice, make sure both are commented out. This is a band-aid / workaround that has worked for me anyway. Make sure to do a php -m to verify it is not loaded.

[netniV]

Disabling openssl will prevent plugins like routerconfigs from working. If you are not using those, it shouldn't be a major issue but do be aware of that.

[kgujas]

thanks , i run php -m and openssl is listed , now i'm trying to find where is it in the file twice

[kgujas]

Hi , i don't see anywhere in the php.ini the second line for openssl , what I see have the ; but when I run php -m openssl is listed ... please some help ...
is any problem with cacti 1.1.36 and php 7.0.25 and mariaDB 10.0.34 ?

[netniV]

@kgujas There may be an easier fix than disabling SSL, please check the PR #1481

[andermat8]

I was going to test this out but under 1.1.37 (dev tree) the Send a Test Email link is broken. I'll try and create a test report instead.

[netniV]

Remind me where the Send A Test Email part is?

[andermat8]

Configuration/Settings/Mail/Reporting/DNS under the Emailing Options section, actually there would be a link on the heading on the far right to send a test email.

[andermat8]

Seems to work after updating functions.php with openssl enabled. Thanks!

Hi , I'm not a big Linux expert , but I need a tool for monitoring my system... My CactiEZ 0.7 works ok . I installed the cacti 1.1.36 with help from tutorial from this site, https://www.itzgeek.com/how-tos/linux/ubuntu-how-tos/setup-cacti-network-monitoring-tool-on-ubuntu-14-04-linux-mint-17.html Maybe something wrong here I don't know ... Can someone give mi a link or tutorial How to install cacti 1.1.36 that works 100% ?

thanks

[kgujas]

everything works OK from this tutorial , except email sending ...

[netniV]

So, that tutorial will get you a linux system running cacti with a mysql or mariadb database. It does not cover, how to install sendmail and/or configure the SMTP settings needed for sending email out. Cacti offers you a couple of options which can be found in Console -> Configuration -> Settings -> Mail/DNS/Reporting (tab)

Your choices are:

• PHP Mail() which will use whatever settings have been defined in the PHP.INI file
• SendMail which will use a local installation of SendMail to queue and ultimately send the messages out. This has to be installed and configured separately to Cacti.
• SMTP which requires you to enter all the details needed to be able to send email out. This normally includes the server that will send email out, a username and password (as a bare minumum). Some others require you to secure the connection too using TLS, etc.

Unfortunately, we can't tell you what they should be because that would depend on your network and configurations. If you already have this working on another server, imitate the settings from there.

[kgujas]

I set up config form email for SMTP , with same settings like on old CactiEZ , but I have error for sending mail

[andermat8]

I'd recommend running wireshark and filter on port 25 while sending the email to see what you get. If you are seeing TLS handshake then security is not disabled. Did you update functions.php with the recommended changes?

[kgujas]

is it in LIB folder ? It's strange but I don't see it in that folder ?

[andermat8]

It is in the cacti\lib folder, not the php\lib folder.

[kgujas]

Thanks you all for help me. Finally my cacti 1.1.36 sending mail OK , success .... I have changed my cacti/lib/functions php with suggested config and it's working now ok.

The functions.php update has now been merged into the develop branch.
