On my server (Debian 3.2.54-2 x86_64 GNU / Linux), I use this command to test the connection to APNS (Apple Push Notification Server):
telnet gateway.sandbox.push.apple.com 2195
Trying 17.172.232.46 ...
Trying 17.172.232.45 ...
Trying 17.172.232.18 ...
telnet: Unable to connect to remote host: Connection timed out
ping gateway.sandbox.push.apple.com
PING gateway.sandbox.push-apple.com.akadns.net (17.172.232.46) 56 (84) bytes of data.
telnet did not help me connect. What is the reason for this?
1) Do I need to ask the administrator to configure the firewall so that telnet goes through port 2195?
2) When we use telnet for a server with this port, which port on our side will be open?
telnet gateway.sandbox.push.apple.com 2195
means that port 2195 on APNS will be open, so which port on our computer will be open to establish a connection?
