Can curl make a connection to any TCP ports not just HTTP HTTPS

Question

Can curl make a connection to any TCP ports not just HTTP HTTPS  I need to check for an open port  for example  11740   Is this possible

User · Answer

Of course   curl http   example com 11740 curl https   example com 11740   Port 80 and 443 are just default port numbers

Yes  it s possible  the syntax is curl  protocol     lt host gt   port   for example   curl example com 1234   If you re using Bash  you can also use pseudo-device  dev files to open a TCP connection  e g    exec 5 lt  gt  dev tcp 127 0 0 1 1234 echo  send some stuff   gt  amp 5 cat  lt  amp 5   Receive some stuff    See also  More on Using Bash s Built-in  dev tcp File  TCP IP

Since you re using PHP  you will probably need to use the CURLOPT PORT option  like so   curl setopt  ch  CURLOPT PORT  11740    Bear in mind  you may face problems with SELinux    Unable to make php curl request with port number
