How to open tls authentification on IBM CLOUD in application mode - ibm-cloud

I am using ibm cloud as mqtt broker and the device is raspberry pi 3. And I have already realized TLS authentification connection in device mode. But I don't know how to open such connection in application mode.
In none SECURE mode, my program is good:
host='orgid.messaging.internetofthings.ibmcloud.com'
clientid='a:orgid:appid'
username='xxx'
password='yyy'
client=mqtt.Client(clientid)
client.username_pw_set(username,password)
client.on_connect = on_connect
client.on_message = on_message
client.connect(host, 1883, 60)
client.loop_start()
But when I tried to use the following code to apply TLS, the server refused me.By the way such code works well in device mode.
client.tls_set(ca_certs="a",certfile="b",keyfile="c"
,cert_reqs=ssl.CERT_NONE)
client.connect(host,8883, 60)

I fixed the problem:
caFile ='message.pem'
client.tls_set(ca_certs='message.pem',cert_reqs=ssl.CERT_NONE)

nginx - Trying to push to facebook live

I try to push stream to facebook from nginx server withi this summary:
- install nginx (with rtmp module) on debian
- nginx.conf
rtmp {
server{
listen 9999;
chunk_size 4096;
application live {
live on;
record off;
push rtmp://live-api.facebook.com:80/rtmp/key;
}
}
}
and error received:
2018/01/23 09:31:10 [error] 6826#0: connect() to [2a03:2880:f002:12a:face:b00c:0:1411]:80 failed (101: Network is unreachable)

Is there something wrong ?
I'm still in searching to resolve this
Thank in advance
replace 'key' from your push URL with your private key found in https://www.facebook.com/live/create
Sometime in peak hour, the facebook RTMP server stop accepting new request. Happened to me so many times while simulcast Youtube/FB Live / Twitch on Nginx RTMP Module.
Another solution is, fire up free tier AWS EC2 AMI Linux, install NGINX with RTMP Module and pushing from there.

Can't get Zabbix to email alerts

I've recently spun up a new Zabbix 3.0 instance on Ubuntu 16.04 using Php 7.0 and I am running into a lot of issues trying to get it to e-mail the Zabbix administrators. We are trying to use Amazon SES to send out the e-mails. For our setup, we have a usename & password that was generated by SES we are using port 587 with SSL/TLS connection. I've made sure that the alert is enabled and that the E-mail media type was enabled as well. I've also double checked the Zabbix is compiled with SMTP & TLS support. I've also verified that the Zabbix server can get to the Amazon SMTP endpoint on port 587. From the messages it seems to be some form of a communication issue, but everything I've tried isn't really getting me anywhere.

Just for reference, I do have Zabbix running off of HTTPS. To get that configured I just made a change to the Apache sites-enabled default file to point to the certificate on the local machine. They are signed certificates. I had also installed the most recent openssl package
Has anyone ran into this issue before or know of what might be happening?
Any help would be appreciated!
Thanks :)
587 is STARTTLS, use 465 for SSL/TSL (don't forget to configure security group):
You may have problems with email/email domain verification. Be sure that's OK.

ADMU0509I: The Application Server "server1" cannot be reached. It appears to be stopped

I have setup a WebSphere Application Server on my RHEL 7 virtual machine. When I start the server, it starts fine and I can access the admin console but when I try to stop or get the status of the server using the script
sh stopServer.sh -server1 / sh serverStatus.sh server1
It gives the following message,
ADMU0509I: The Application Server "server1" cannot be reached. It appears to be stopped.
My wsadmin scripts are not working, when I run the script
sh wsadmin.sh -user wasadmin -password Password
I get the following error
WASX7023E: Error creating "SOAP" connection to host "localhost"; exception information: com.ibm.websphere.management.exception.ConnectorNotA
vailableException: [SOAPException: faultCode=SOAP-ENV:Protocol; msg=; targetException=java.net.MalformedURLException]
WASX7213I: This scripting client is not connected to a server process; please refer to the log file /opt/IBM\WebSphere/AppServer
/profiles/AppSrv01/logs/wsadmin.traceout for additional information.
I can access the console on the browser without any issue.
To expand on this more specifically. The file ssl.client.props looks like this typically around the com.ibm.ssl.protocol property:
$ grep -i tls -C 2 /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/properties/ssl.client.props
#-------------------------------------------------------------------------
com.ibm.ssl.alias=DefaultSSLSettings
com.ibm.ssl.protocol=SSL_TLS
com.ibm.ssl.securityLevel=HIGH
com.ibm.ssl.trustManager=IbmPKIX
--
#-------------------------------------------------------------------------
#com.ibm.ssl.alias=AnotherSSLSettings
#com.ibm.ssl.protocol=SSL_TLS
#com.ibm.ssl.securityLevel=HIGH
#com.ibm.ssl.trustManager=IbmX509
This property can take a number of values:
This property is the SSL handshake protocol that is used for this SSL
configuration. This property attempts Transport Layer Security (TLS)
first, but accepts any remote handshake protocol, including SSLv3 and
TLSv1. Valid values for this property include SSL_TLS, SSL, SSLv2
(client side only), SSLv3, TLS, TLSv1, SSL_TLSv2, TLSv1.1, and
TLSv1.2.
These values are described in this table:
References
ssl.client.props client configuration file
Appendix A: Protocols and Cipher Suites
For me this problem came when the security level of the WAS was not consistent.
In the IBM console, it was set to TLSv1.2 and in ssl.client.props file it was set to SSL_TLS. Once they were changed to the same value my console could connect to WAS.

Indy10 HTTPS - socket error 10060 - connection timeout

I'm getting "Socket Error #10060, Connection timed out" when trying to access a https link.
Here is how you can reproduce it with INDY 10.6.2.0 and OpenSSL 1.0.2d DLLs (also happens with older Indy 10 version and dlls):
create a project and add a TButton, TIdHTTP and TMemo objects to the form
add to button onclick this code:
IdHTTP1.Request.UserAgent:='Indy';
IdHTTP1.HandleRedirects:=true;
Memo1.text:=IdHTTP1.Get('https://www.itv.com');`
now compile and run it, it will download correctly the file.
BUT if you are using a service like www.smartydns.com which redirects DNS request to their server, INDY sample above will not work and fail with "Socket Error #10060, Connection timed out" message.
Have tried it with WGET too (https://eternallybored.org/misc/wget/) and in version 1.13 its initializing the SSL handshake and freezes, but works without problems with version 1.15.
So the question is, what IdHTTP settings do I have to use to make it work, or is it a bug in Indy10 ?

Fiddler Error Connecting to HTTPS Applications !SecureClientPipeDirect failed

Fiddler Error Connecting to HTTPS Applications
Fiddler Log:
!SecureClientPipeDirect failed: Authentication failed because the remote party has closed the transport stream. on pipe to (CN=services.bigpond.com, O=DO_NOT_TRUST_BC, OU=Created by http://www.fiddler2.com)
I have followed other posts but no answers
The typical explanation for this message, as documented in many places, is that the client application has not been configured to trust Fiddler's root certificate. As such, the client closes the connection to Fiddler when it sees the untrusted certificate.

In Kestrel I'm using an SSL cert.
I 'downgraded' the TLS protocol in order to get this to work.
This is not something you'd do in production - but in production you shouldn't be using kestrel. I'm not saying this is the best overall config, but this is mainly to show the SslProtocols option.
WebHost.CreateDefaultBuilder(args)
.UseKestrel(options =>
{
options.Listen(IPAddress.Any, 5000); // http:localhost:5000
options.Listen(IPAddress.Any, 44300, listenOptions =>
{
// https://dotnetthoughts.net/enable-http2-on-kestrel/
//listenOptions.Protocols = Microsoft.AspNetCore.Server.Kestrel.Core.HttpProtocols.Http2;
listenOptions.UseHttps(#"S:\WORK\SSL\example.com.pfx", "cert-password", httpsOptions =>
{
httpsOptions.SslProtocols = System.Security.Authentication.SslProtocols.Tls;
});
});
})
.UseStartup<Startup>();
