Cannot make a connection to the Telnet Server

Either
- wrong IP address for the Telnet Server
- The Telnet server is not running
- A firewall stopping access on port 23.
- The iPhone/iPod is not on the same network as the Telnet Server

 
 

How to connect to a Telnet Server from the Internet (EDGE)

To allow a connection with the iPhone on the EDGE network or another wifi network, maybe at your local Cafe, you must configure the router/firewall protecting your office network to allow traffic on port 23. This could be a security risk! Read the router manual for advice.
 
An example:
 
I have a router at my office, which connect to the Internet. It has IP address 88.1.2.44 on the Internet. The router has a fixed IP address on the Internet, if your internet provider (ISP) gives a dynamic address, a solution could be to use a service as NO-IP
 
Our Office Linux PC has a fixed IP address on the local network (wifi) at 192.168.2.2
 
In the router firewall configuration I have configured, if it receives data on port 23, forward it to 192.168.2.2.
 
When on the EDGE network with the iPhone, I will in Telnet as Server IP address write
 
  • 88.1.2.44 , and as port 23 (Not the IP address for the Linux box!)
 
 

How to enable the Telnet Server in Mac OS X Leopard (10.5)
