I'm trying to make my RMI service work across a Firewall. I followed instructions in this answer to run both RMI Registry and my RMI service on port 1099, yet, I'm seeing different port numbers being opened on RMI client and server when I do netstat .

Firewall impeding Bonjour network debugging

由 白昼怎懂夜的黑 提交于 2019-12-08 04:18:36
问题 I’m trying to debug a Bonjour network routine, and every time I run it, the Mac’s firewall asks “Do you want the application ProjectName to accept incoming network connections?” I click “allow,” give it the administrator name and password, and the app is duly added to the firewall’s list of allowed incoming-connections apps…until the next run. Debugging this sync routine is cumbersome as it is. It’s really a nuisance having to type in the admin and password for every run. Of course I could

How to avoid client firewall closing connection because inactivity while processing data on Grails

由 痴心易碎 提交于 2019-12-08 04:04:00
问题 I have one Grails working on the server on Tomcat. This app is an web interface to export information from the MySQL server. This information can be exported depending on the selection that you did, but takes some time. The biggest part or process is around 40min. This is the time that it needs to export all the information from the database and return to user compressed in one zip file. Everything is working correctly but we have a problem with one client.

Opening open GCE firewall on elasticsearch instances for external connection

由 前提是你 提交于 2019-12-08 00:40:54
问题 I've just created a elasticsearch cluster in GCE using "Click to Deploy", but I can only access it by using a tunnel. This is not a choice in my case, since there are other developers that I don't want to give gcloud access to. I would like to open port 9200 for elasticsearch so they could just connect to it by IP address and not with tunnel. How can I achieve this? 回答1: Open port 9200 in your GCE firewall for the elasticsearch instances. elasticsearch instances created by "Click to Deploy"

What firewall ports do I need to open to allow Sinch and WebRTC to work?

由 扶醉桌前 提交于 2019-12-07 13:30:50
问题 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
