RE: Port binding problem
Google/translate0Thank You!0Good Post!0Bad Post! link
If I dont't login to love0day@warchall to execute the curl command, I can't control my local port even if 4200.
But I can control my port to 4200 when I execute the command after ssh to love0day@warchall.So It must be the casue of ISP.
I don't know why it must be 42. There is some difference between them? I know use what parameter of curl,but the port number make me crazy.

"So It must be the casue of ISP." This doesn't just follow. As I said before, do some research first.

If you want you can PM me with what you are trying exactly and what the result is, without spoiling it for others.

With curl from any port less than 1024, this problem is not working. The tshark output shows the connection is made from local port 42 but the problem page shows a random port number. While with any port greater than 1024 the problem page and tshark output shows the same port number. Why?

Do you understand the difference between "remote port" and "server port"? (naming may vary)
