Unable to add service client for a net.tcp WCF service
I am trying to add a client for a WCF service that is net.tcp based. When I use “Add Service Reference” and provide this URL:net.tcp://localhost/service1.svc, it gives following error.

How can I configure a reverse SSH connection to the connecting computer?
I’m going to be deploying a number of machines in the near future which will be behind routers. It won’t be feasible to set up dynamic DNS on each router and port forwarding, so is there a way I can configure these machines to initiate a TCP connection to my computer and then have my computer initiate a SSH connection to the remote computer over that connection?
Allowing a user to let listen to a port below 1024
I need to allow a user (different from root) to run a server listening on port 80.
Is it better to set -j REJECT or -j DROP in iptables?
There’s an example of iptables rules on archlinux wiki:
How to close ports in Linux?
I have some question in closing port, I think I got some strange things.
Simple way to create a tunnel from one local port to another?
I have a development server, which is only accessible from 127.0.0.1:8000, not 192.168.1.x:8000. As a quick hack, is there a way to set up something to listen on another port (say, 8001) so that from the local network I could connect 192.168.1.x:8001 and it would tunnel the traffic between the client and 127.0.0.1:8000?
Redirect stdin and stdout to ports
I’d like to take a program P that reads from stdin & writes to stdout, but connect it to nc or whatever such that it reads from a certain port and outputs to another port.
/dev/tcp not present in Linux
I am porting C/pro*c code from UNIX to Linux. The code is:
Why are the first 1024 ports restricted to the root user only?
This is more idle curiosity than anything else. A friend of mine asked me ‘which port range is it that only root can use under Linux?’ I told him 0-1024 were restricted. Then he asked my why it was so and… I was at a loss. No idea whatsoever.
Kernel socket structure and TCP_DIAG
I’m working on a software which connects to a Real Time data server (using TCP) and I have some connections dropping. My guess is that the clients do not read the data coming from the server fast enough. Therefore I would like to monitor my TCP sockets. For this I found the “ss” tool.
