I am currently working with ATWINC1500 wifi network module on their WiFi click7 board which communicate with PIC32 (FreeRTOS Curiosity PIC32MZ EF).
I'm trying to create tls client example (TLS 1.2) using MPLAB Harmony v3. Socket has been opened successfully, I got the hostname and its IP address, but when I call the connect API, I got the SOCKET_MSG_CONNECT callback with error code (connect aborted). it's related to the certificate??
How installing the root certificate of my server in ATWINC1500 using MPLAB harmony v3.
How I can verify that my certificate has been installed
In Harmony 3, I need the setting of cipher suites or they are enabled by default, because I found this API (WDRV_WINC_SSLActiveCipherSuitesSet) but it's not used.
Thanks.

I've been having a lot of problem to make my target setup work: hosting a headless server on GoogleCloudService, that webGL clients hosted on a platform like itch.io could connect to. I'm using Mirror and its SimpleWebTransport for connecting.
The server runs fine, and I can connect from my local server browser when SimpleWebTransport's "use WSS" and "use SSL" bools are off.
When uploading the build and running the client through itch.io tho, it's giving an error saying it needs to use WSS to connect.So I re-uploaded everything with the WSS and SSL options ticked on the SimpleWebTransport. I've also followed a guide to activate a load balancer and make an instance group so I could have a google-managed SSL certificate produced.
Now trying to connect this way gives me a new error (cf attachement).
What could I be missing setup wise? I see in the SimpleWebtransport there's a field for a path to the certificate, should I be using it and how? I do see the following error in my server's console:
FileNotFoundException: Could not find file "/home/saturn_slides_gmail_com/cert.json"
Also, is it ok that i'm using port 7778 in Mirrors' setup as well as in GCS's instance group settings? Or should i be using some other ports.
thank you !
I'm a new comer to using the overseas server. Recently I bought a vps from virmach in order to see foreign websites like google and wiki.
I've been trying for a long time configuring my shadowsocks on my server.
However, when I was using shadowsocks-qt5 to connect my server, it was timeout.
And of course I can't access google correctly.
What I want to ask is the reason why I failed.
Here are things that I do remember to do:
stop the firewall on both computers;
build the .json file which I referred to blogs in China.
Here are the outline of my shadowsocks.json on my server:
{
"server":"0.0.0.0",
"server_port":8388,
"local_address":"127.0.0.1",
"local_port":1080,
"password":"XXXX",
"timeout":600,
"method":"aes-256-cfb"
}
Other useful(maybe) information:
my client OS version: Ubuntu 18.04.3 LTS
my server OS version: Ubuntu 16.04.6 LTS
the client I choose is from: https://github.com/shadowsocks/shadowsocks-qt5
I could not help but wandered, are there any other possible reasons I've forgot? Can anyone inform me some helpful details to solve this puzzling problems? Thanks a lot!
I have not set up my own VPS but I have instead subscribed to the server provided by caonima.io, so I can't speak for any server related issues. Additionally, I have no affiliation with caonima.io. I did however successfully set up my client on Ubuntu 16.04 after having some issues connecting to GFW-blocked (China's Great FireWall) websites.
From what I understand from my solution, the client configuration is NOT the only step of setup. There are two layers of proxy access that need to be completed:
Client Configuration. Configure your client with the server and connection information. A successful connection looked like this for me with my command line interface
shadowsocks-libev command line client successful connection
System or Browser Proxy Configuration. You will need to configure either your browser or web access tool to use a proxy, or set system-wide proxy settings. To set system wide proxy settings, go to system settings > network > network proxy and enter the proxy information. Setting Socks host to localhost:1080 resulted in successful GFW-blocked website access (as shown below)!

I have a program on my computer that runs as SYSTEM and it is trying to launch an exe(opc server) on a remote machine x.x.x.x. But I get a DCOM error in my machine's eventviewer.
DCOM got error "2147942405" from the computer x.x.x.x when attempting to activate the server: yyyyy
I followed almost all the suggestions on the internet about opening dcomcnfg and adding users limits.default for launch and activation and Everyone,system,interactive,network from link (ftp://ftp.softing.com/pub/outgoing/opc/DCOM/DCOM-Settings-en.pdf) but nothing works.
Would anybody have nay other ideas on how to make this work.
According to MS Technet:

With my VERY limited understanding of Certificate servers you may have one of the scenarios:
Client PC's are trying to connect to a Certificate server that no longer exists
Client PC's have a certificate that is valid but the Certificate server no longer exists
A Certificate server is broken
Clients do not have the proper authority to request the Certificate
I say this is limited knowledge as I am currently trying to remove AD Certificate services from a Domain Controller and I can see that in the System event log the exact same messages are being logged as I have stopped the Certificate services to asses the impact. If I get further information I will post back.
My play framework web application sends automatically emails to user using Apache commons email library, everything works fine on my machine, but when I deploy it on an Ubuntu server it is unable to send email.
It throws exceptions like org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.googlemail.com:465 (I also tried different configuration with smtp.google.mail port 465,25 and 587 with or without ssl and tls)
and connection timed out.
I starting to believe that is a problem of some configuration of my ubuntu server.
Any suggestion?
If i type ufw status command I receive status disabled.
Thanks
I am going to close this question, because I found the solution. Basically my Server provider (Scaleway) has a security configuration where SMTP is blocked. I asked them to unlock It.
I am trying to connect to ejabberd server using smack API 4.1.2 (no asmack) on android device. while running smackClient program , I am getting below error
java.net.SocketTimeOutException:Failed to connect to abc.example.com/182.*.*.* (on port 5222) after 30000ms,'abc.example.com:5222' failed because java.net.ConnectionException: Failed to connect to abc.example.com/182.*.*.* (on port 5222) after 30000ms
Connection to same ejabberd server using same android device is working fine using xmpp clients like xabber. so Issue is surely with client code I have written. Below is the snippet of my code
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
.setUsernameAndPassword(userName, password)
.setServiceName("abc.example.com")
.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setSendPresence(true)
.build();
connection = new XMPPTCPConnection(config);
connection.connect();
connection.login(userName, password);
I am missing something in my client code that xabber is having so xabber connection is working from same device using same credential.
Please help
Hard to tell without real IP and names in your example. However, my best guess would be about how the address to your IP server is resolved.
There seems to be discrepancy in your example with server (example.com) and service name in your code (abc.example.com).
My guess it that your client is attempting to connect to another machine that the one the XMPP server is running on.
So, here are the things to check when you have issues with a server not replying:
Check how the address of the domain is resolved. You may need to specify another machine name that the domain. If this is a test domain, there is possibly not a DNS setup, so you may even need to specify server IP (while still configuring the client to use an XMPP domain, that's two different things).
In client, log the IP you are trying to connect to, to make sure this is the one where the server is running.
If server is not on the main domain server, you may even need to do DNS SRV record queries for XMPP C2S service.
For me , it took hours to find the solution.
I forget to turnoff the VPN application(Express VPN) .Network tunneling was the root cause .
And change the Network protocol version properties as below ,
Choose the 1st option (Obtain DNS server address automatically).
My experience: I used following code
DomainBareJid xmppServiceDomain = JidCreate.domainBareFrom("desktop-urvfr83");
//DomainBareJid xmppServiceDomain = JidCreate.domainBareFrom("192.168.1.3");
InetAddress addr = InetAddress.getByName("192.168.1.3");
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
.setUsernameAndPassword("alir", "111111")
.setHostAddress(addr)
.setResource("phonn")
.setXmppDomain(xmppServiceDomain)
.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setPort(5222)
.build();
but it could not connect and produced timeout connection exception. When I disabled windows firewall it worked correctly and connected.
