Hosts file changes don't apply for TCP connections
0
A program on my windows PC makes a TCP connection to a IP address e.g.
122.122.122.122
I have made a TCP server on my local machine and made the following change in my hosts file
192.168.1.123 122.122.122.122
because I want that program to connect to my server instead of 122.122.122.122
the problem that the program is still connecting to 122.122.122.122 instead of my server and ignoring hosts file changes.

In most OSes, the hosts file is only for name to IP address mappings, not for replacing one IP address with another. So I wouldn't expect this to work.

Additionally to the comment from Spiff the syntax is wrong: it should beIP namesand notname IP, i.e. the IP which should be used for the given name is in the first column.

Does the program really use a hard coded IP rather than a name? How do you know it makes a connection to that IP? Curious to know how you've determined this.

@SteffenUllrich Sorry, I just edited that, it's not like that in my hosts file

You can't reroute an IP address using the hosts file. If your program binds on all interfaces, you can probably bring up a secondary interface with the IP 122.122.122.122 (netmask 255.255.255.255)
