Please, help

More info needed

To help you, more info is needed.

1. Zabbix sends email to the local port 25 (mail client like postfix/sendmail)

-If this is the issue, check the zabbix logs on why. Zabbix > administration -> audit or check the actual zabbix logs.

2. your mail client forwards it to a different server.

-if you have ISP that blocks 25 out, you need to setup a relay server of your ISP in the postfix/sendmail.

-if you have all ports open, check logs like /var/log/maillog if the mail was received locally and forwarded to a different server. The log will tell you which server it was forwarded to or if it's in the deffered queue.

Regards,

Luke

1) In dashboard and audits I have something like this:

I don't see anything about sending emails.
2)
I have something like this:
root@ht-50814ffc17b2c:/etc/zabbix/alert.d# sudo netstat -ntlp | grep :25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 621/sendmail: MTA:
Is this mean that 25 port is open?

I don't have this location /var/log/maillog

In var/log/ I have only:
alternatives.log.1 dpkg.log mysql.err syslog.3.gz
apache2 dpkg.log.1 mysql.log syslog.4.gz

In logs of Zabbix Server I find something like this:

I used chmod 755 on this files. Is this case in this situation?

[lukeiam]

Which mail client is your Linux using?

I try to used two clients. One is Msmtp and second is sendmail.

I was going to mention on another post of yours that the scripts were owned by root. Why don't you chown them to zabbix.zabbix and see if that helps?

Also, why is the log message showing double slashes?

sh: 1: /etc/zabbix/alert.d//zext_msmtp.sh: Permission denied
sh: 1: /etc/zabbix/alert.d//gmail.sh: Permission denied
sh: 1: /etc/zabbix/alert.d//gmail.conf: Permission denied

I am probably looking like a noob, but I don't know how to do that I don't know what You mean by that.

Also, why is the log message showing double slashes?

sh: 1: /etc/zabbix/alert.d//gmail.sh: Permission denied

sh: 1: /etc/zabbix/alert.d//cli_sms_clickatell.php: Permission denied

Again, I don't know why. Wgat should I check?

[tchjts1]

When you see "permission denied", it generally means that the user trying to execute the scripts, doesn't have permission, for whatever reason.

In your other post, I saw that the scripts were owned by user "root" and group "root". Probably your Zabbix server is running as user zabbix. You can tell this by running ps -ef|grep zabbix

But you also show that you chmod'd it to 755, meaning all users have permission to execute it. So I don't know where the permission denied is coming from.

[kqfp31]

I have something like below. What this is mean. Is this mean that user Zabbix have only permission to this locations?

[Colttt]

chown zabbix.zabbix /etc/zabbix/alert.d/*

some log-information?!

please login as zabbix-user and try you scripts!

[tchjts1]

To do what Shadow suggests, you can assume the zabbix user by doing sudo su - zabbix and entering your password for the root user.

Now that you are user "zabbix", you should be able to see where the issue lies. Try navigating to your scripts dir and running some of them.

[kqfp31]

But when I am doing this command, nothing happend:


Which logs should I check?

[Colttt]

grep -i zabbix /etc/passwd

which shell do you have?! /bin/false ??
when yes, you must set it to /bin/bash.. otherwise zabbix can´t login

[kqfp31]

How to do this?

root@ht-50814ffc17b2c:~# grep -i zabbix /etc/passwd
zabbix:x:110:115::/var/run/zabbix/:/bin/false
