I'm working on a QT app for OS X that uses multiple executables. We sign the .app by signing each executable within the .app, then signing the whole .app with the "-f" option. This is the procedure Apple recommended when we contacted them. However, each time our app starts, the user is prompted with a warning that our application wants to connect to the internet. This warning is repeated every time the application is restarted, even if the user chooses to grant it access. Any suggestions for where our process could be going wrong would be useful. For what it's worth, all executables and the

Sinch has been working just great over the internet and various NATed networks. But I've just tried the device behind an enterprise firewall, and suddenly we can't make calls. More specifically devices can call each other, but the moment onCallEstablished is called (audio streams are connected), the calls drop out. No audio from the remote end is ever heard. It definitely only happens on this particular network. I'm assuming that this is a firewall issue, but have no idea what ports we need to have opened on this firewall to allow the voice calls? Edit: Whilst experiencing this issue, I was

Step error: 1. sudo ufw enable 2. Command may disrupt existing ssh connections. Proceed with operation (y|n)? y 3. exit Before ssh again and can not access. On Security Group, port 22 is opening But firewall disable port 22. How to access server again? You could use the following simplest way (user-data) to turn off the ufw then access the instance and edit your firewall. stop the instance Edit the user data to disable the ufw once and let you access the instance start the instance Following is the user data: Content-Type: multipart/mixed; boundary="//" MIME-Version: 1.0 --// Content-Type:

My Spring application is running on a machine that is behind a NAT firewall (pfSense). The machine's internal IP is a.b.c.d , and the NAT IP is w.x.y.z The Spring configuration's serviceUrl is set to my internal IP ( a.b.c.d ) on port 1100 , and when I start the application, I provide the following switches: -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=w.x.y.z -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false As shown above, I set -Djava.rmi.server

Does anyone know why Eclipse is asking for incoming network connections? I searched around and saw mentions of Code Completion with PyDev, but I disabled code completion in PyDev, restarted, and was still prompted for incoming network connections. PyDev spawns a shell and connects to it to request information on builtin modules (besides using it to debug a process). I.e.: The shell is spawn at https://github.com/fabioz/Pydev/blob/master/plugins/org.python.pydev/src_completions/org/python/pydev/editor/codecompletion/shell/PythonShell.java and used in: https://github.com/fabioz/Pydev/blob/master

I'm attempting to set up an environment in which a TransactionScope originating on a web server (asp.net) will flow a transaction through WCF to an application server and subsequently through to the database. Since I'm forced to use a SQL Server 2005 database, this often causes the transaction to be 'promoted' to a distributed transaction (several service calls could be wrapped in this TransactionScope), which means the Distributed Transaction Coordinator needs to be enabled. I've successfully got it working on a local box where the web server and app server are hosted on the same machine,
