Does any one know how to setup a function FTP test
Like: check that user A can do a login and logout on ftp server.

Set up a shell script which does it for you. You can make it in whatever script language you feel comfortable in.

Any suggestion how to do this script?.

Any suggestion how to do this script?. or how to get the data faield to zabbix?

#!/bin/sh
HOST='ftp.users.qwest.net'
USER='yourid'
PASSWD='yourpw'

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
quit
END_SCRIPT
exit 0

I would probably go with a PHP script and use cURL for accessing the FTP server, but that's since I have most experience in coding PHP scripts, so it depends on what you prefer.

Hi

if you have curl installed on your ZABBIX-Server, and most of
us have it, because of the Web Monitoring part, then use it
in an external script.

You can specify some or all parameters (hostname, username, password)
either in the ZABBIX item of type External check or hardcode
it in the script.
Place the script in the directory where the configuration parameter
ExternalScripts in your zabbix_server.conf points to, set the execute
permissions correctly and start checking the FTP login.

The script basically looks like

curl ftp://username:password@host >/dev/null 2>&1
echo $?

The first parameter of the script is set by ZABBIX to the item's
hostname. If you want to check this host, just use this.

To enhance this solution you could add a valuemap for the exit codes
of curl and specify it in the configuration of the item.

HTH,

Norbert.

Sounds great :-)
When checking if curl i can se that
[root@zabbixdb1 ~]# /usr/bin/curl -V
curl 7.15.5 (i686-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5
Protocols: tftp ftp telnet dict ldap http file https ftps
Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz

And the script is added to:
[root@zabbixdb1 tmp]# more /etc/zabbix/externalscripts/ftp_check
curl ftp://test:´xxxxxx@xxxxxx >/dev/null 2>&1
echo $?

But how do i integrate this in zabbix?

Add an item of type External check to the host,
set whatever you like as the description and set ftp_check[] as the Key.
Type of information: Numeric (integer 64-bit)
If you want you can define a value map for the curl return values.
Be sure to set the right permissions for the script !
The settings depend on your setup. The easiest but not the safest (everybody can read
the script and the password in it) way is to do a chmod 755 ftp_check.

In the same simple way any Nagios plugin can be used.
Just ignore the output (after testing that it works) and pass the exit
code to a ZABBIX external check.

We use this just for remote checks like LDAP, DNS, etc.

Be aware, that this needs resources so you should not use
it for all possible checks.
Although it would be possible to do some checks (like number of processes running) via Nagios' check_by_ssh plugin: don't use it.
That's why there is a ZABBIX agent doing active Checks.

Because most of the Nagios plugins return the response time, we
use zabbix_sender in the check script to store those values in ZABBIX, too.

Norbert.
