Squid Proxy Server - Port numbers - HTTP - HTTPS etc

in flag

I have a virtual proxy client and I have a squid proxy server.

root@arch:/etc/squid # cat /etc/squid/acls/ports.acl
80 # http
21 # ftp

root@arch:/etc/squid # cat /etc/squid/acls/sslports.acl
443 # https
3001 # ntop

I am curious about port numbers and squid. I know that the port number is not "magic", you can use any port from 1-65535 you like. Ports in the range 1-1023 are "well-known ports" which are assigned worldwide to specific applications or protocols.

But basically, I want to understand that when I change 443 to something else or when I add port numbers like

root@arch:/etc/squid # cat /etc/squid/acls/sslports.acl
4888 # https
3001 # ntop

What is the matter? I have a proxy server and another client machine. I am trying to see these changes on the client machine browser but nothing I can see. For example: https://www.example.com:443 works

But I change https https://www.example.com:4888 , isn't it supposed to work also?

Can you please help me to understand?

What do you mean by "supposed to work"? Did something fail? What exactly failed? What errors did you receive?

root@arch:/etc/squid # cat /etc/squid/acls/sslports.acl 4888 # https 3001 # ntop In this configuration, I was thinking that https websites now has port number 4888 So, if I browse to https://www.example.com:4888, I was expecting to see the normal page. But instead, I got problem loading page.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
