Hello,
So i have 2 VPS's, i try to connect to a remote server

the remote server is configured (i believe php code) to block connections from severs. you can only access itif you are browsing from home or something like that

but my case is, i can connect them from one vps but the other vps is denied.

I wonder how the remote server knows this connection is from a server or from a normal internet browser

thanks

Mostly likely the case is that a firewall is simply blocking the access completely. From that browser command prompt, you can run iptables -L to list the rules. iptables -F would flush the rules, but not save it. The way to save the rules depends on your distribution.

From a browser, it isn't using your workstation to connect. It is providing you a window to send a command and PHP processes that and uses a shell function to execute it and returns you the result. I doubt you are using SSH in this case. Now if you are using SSH, the PHP script could add allow your IP address by adding a rule to iptables and then remove you, but I highly doubt this.
