Why is Exceed using Ports 7, 23 or 37?

LAST MODIFIED DATE: September 24, 2004

VERSION: This applies to Exceed version 7.0+

PROBLEM:

Running a packet trace, you may notice that Exceed may be sending icmp packets on ports 7 (echo), 23 (telnet) and 37 (timeserver). Depending upon your firewall configuration this may be causing problems.

SOLUTION:

Exceed uses this mechanism to help resolve the local IP address. It is most common in a multi-homed system. By default Exceed will use the above mentioned ports.

You may add the following registry key:
\HKEY_LOCAL_MACHINE\Software\Hummingbird\Connectivity\<VersionNumber>\Exceed\Transport
Then add the string TCPPorts and set a value to a port(s) of your choosing.

The TCPPorts value is a string of the port numbers separated by commas, or blanks.
For example, to use HTTP and Telnet ports you can create the following value:
TCPPorts = 80,23

If you wish to use UDP rather than TCP, change the name of the string to UDPPorts.
