Windows Agent compiled without TLS support

[mrogers-9898]

Hey All,

The Zabbix agent for Windows has not been compiled to support encryption.

When starting with any encryption related parameters it spits out

zabbix_agentd.exe [17072]: "TLSConnect" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd.exe [17072]: "TLSAccept" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd.exe [17072]: "TLSPSKIdentity" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd.exe [17072]: "TLSPSKFile" configuration parameter cannot be used: Zabbix agent was compiled without TLS support

There is a ticket about it - https://support.zabbix.com/browse/ZBXNEXT-3047 - should anyone want to vote to assist getting it actioned.

Has anyone compiled the Windows agent versions themselves with TLS support?

[mrogers-9898]

I've been able to figure out how to compile the agent on Windows.

But I've not been able to figure out how to alter the configuration so it compiles with TLS support.

The src comes with makefiles for the Windows agent, but I cannot for the life of me figure out how to change them for TLS.

I can see in the (bash?) configure script, these values are added if we option for SSL and it passes verification;

OPENSSL_CFLAGS=-I/usr/include
OPENSSL_LDFLAGS=-L/usr/lib
OPENSSL_LIBS="-lssl -lcrypto"
found_openssl="yes"

Obviously those paths are not Windows paths.

[mrogers-9898]

I've made some slow progress. Perhaps someone with some Windows C++ dev work can shed the light on where to go next.

I got the makefile to enable openssl through adding a few values at the top, which they persumably populate through proper switches, which I can't find documentation for.

Makefile_tls.inc

TLS = openssl
TLSLIBDIR = E:\openssl
TLSINCDIR = E:\openssl-1.0.2f

So it attempts to compile, however I get compiler errors.

Hi,

I've successfully compiled the agent version 3.0.1 for Win64 platform.

OpenSSL 1.0.2.7 is used.

Microsoft Visual C++ Redistributable is required (https://www.microsoft.com/fr-FR/down....aspx?id=48145).

You can download it here : http://dl.free.fr/mEJSaErXp

Regards,

[mrogers-9898]

oh that's great!

Would it be possible for you to outline at all your process?

[dedisoft]

- You must have Perl and a C compiler (I use Visual Studio 2015)
- Download OpenSSL and Zabbix Source
- Compile OpenSSL (see Readme)
-Modify the file zabbix/src/libs/zbxsysinfo/common/system.c like this :

(at line 68), replace :

/* timezone offset */
#if defined(HAVE_TM_TM_GMTOFF)
gmtoff = tm->tm_gmtoff;
#else
gmtoff = -timezone;
#endif

By :

/* timezone offset */
#if defined(HAVE_TM_TM_GMTOFF)
gmtoff = tm->tm_gmtoff;
#else
#ifdef _WINDOWS
gmtoff = -_timezone;
#else
gmtoff = -timezone;
#endif
#endif

Set CPU, TLS, TLSLIBDIR, TLSINCDIR variable and compile Zabbix.

That's done.

Regards,

I need Zabbix Agent 3.0.4 openssl 1.0.2h Win64
Where can I download it?
I tried to compile it, but without success.
Alternatively, I would ask for instructions to compile
