port

问题 I have a Red Hat server running tiger-vncserver. This is a hardened system and security doesn't like having so many ports open for VNC users so currently we have 15 (5901-5915). We are getting more users onboarded and anticipate more users after, not sure how many though. Is there a way to make every user have a stateful VNC connection available but share ports? From security's perspective, we would only use like port 5900 or something. If it matters, I am using Apache Guacamole in lieu of a

问题 can't connect to an dotnet app running in an aws EC2 instance on port 7070 I've added the port to the security group and when I check if the port is open (netstat -ntlp) I get the output below: tcp 0 0 127.0.0.1:7070 0.0.0.0:* LISTEN 27021/dotnet Is there anything I'm missing? 回答1: I was able to fix the issue by downloading nginx to my EC2 instance (https://gist.github.com/soheilhy/8b94347ff8336d971ad0) and forwarding my custom port to port 80 Hopefully this will help! 来源： https:/

问题 I am connecting through a QTcpSocket to a QTcpServer . I can specify the listening port on the Server side, but the client chooses a random port for its connection. I have tried to use the method QAbstractSocket::bind but that made no difference. Here is my code: void ConnectionHandler::connectToServer() { this->socket->bind(QHostAddress::LocalHost, 2001); this->socket->connectToHost(this->ip, this->port); if (!this->socket->waitForConnected()) { this->socket->close(); this->errorMsg = this-

问题 My website (https://www.tjbrackett.com/contact), which is on Apache, cannot access my Express app that is on the same server over HTTPS. Before I added an SSL certificate to the site, the setup ran perfectly. When I revert the SSL cert, it works again. The error I'm receiving on the front-end is ERR_CERT_AUTHORITY_INVALID. I've tried setting up a proxy/reverse proxy. I'm not sure if I set them up correctly. I've done a self-signed SSL cert on the Express app. I've tried to serve the Express

问题 I'm working on a project where we want to assign a whitelist packet filters for incoming traffic on a firewall and we are using python script with requests library to make some https requests to some servers outside of that network. For now the script is using ephemeral ports to connect to the servers, but we would like to make these https requests through specific ports. This would allow us to create strict whitelist for these ports. How can I specify the port to the requests library through

问题 I have installed sun jdk 1.6 x64 and tomcat in a linux x64 machine through ssh, i don't have root privileges so i installed both in my home dir. I managed to successful run tomcat but if i try to enter mydomain.com:8080 there's no answer from the server.
