Situation: Some firewalls only allow a single
pcAnywhere host to use an IP port. Additional pcAnywhere hosts behind that
firewall must use different ports. You want to know how to change these
ports.
Solution: Changing pcAnywhere IP ports involves editing
the Windows registry. If you need to do this frequently, creating .reg files is
the safest and most convenient way to make the change. This is particularly
handy for remotes that may have to connect to more than one host behind the
firewall.
To create the .reg file:
1. Click Start, and then click Run. 2. Type regedit in the
Open window, and then click OK. 3. Locate and select the following
key: HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\pcAnywhere\CurrentVersion\System
4.
Click Registry and then click Export Registry File. The Export Registry File
window appears. 5. Enter a file name (this could be a name such as 5631.reg
for the standard port numbers, or any significant name), and save the file to
the desktop. 6. Close the registry and navigate to the newly created .reg
file. 7. Right-click the file and click Edit (left-click will import the
file back to the registry). 8. Delete all but the following
lines:
You can use this file both as a template to
create .reg files for additional ports and as the .reg file to restore
pcAnywhere to its default port values.
To create a .reg file to change
pcAnywhere to a different set of ports:
1. Copy the default .reg file and rename the new copy. 2. Right-click
the new .reg file and click Edit. 3. Change the DWORD value for each
port. IMPORTANT: These values are in hexadecimal. You must replace
them with the hexadecimal values of the new port numbers. For assistance with
determining the hexadecimal values, please see the section How to determine
hexadecimal values below. 4. Save and close the file.
Repeat this
process for as many hosts or remotes as
required.
Example
The default pcAnywhere port numbers
are 5631 (DataPort or TCP) and 5632 (StatusPort or UDP). The hexadecimal
values of these ports are 15FF and 1600, respectively.
You create a new
.reg file to change the pcAnywhere ports to 5641 (TCP) and 5642 (UDP). The
hexadecimal values of these ports are 1609 and 160A, respectively. The
contents of a .reg file with these values will look like
this:
To
change the port values of pcAnywhere, double-click this file. This imports the
new values into the registry.
Port Matching
A
pcAnywhere remote does not necessarily have to be set for the same IP port as
the host. However, some firewalls may be configured so that the pcAnywhere
remote must respond on the same port as the host, otherwise, they will not
connect. In this type of situation, the remotes must match the ports for the
hosts.
Restricting pcAnywhere Ports
You can force a
pcAnywhere host or remote to use only the registered ports. To do this requires
a registry change.
1. Click Start, and then click Run. The Run window appears. 2. Typeregedit in the Open box and then click OK. The registry editor
opens. 3. Locate and select the following
key: HKEY_LOCAL_MACHINE\Software\Symantec\pcAnywhere\CurrentVersion\System
4.
Click Edit, point to New, and then click DWORD value. A new DWORD value
appears in the right frame. 5. Give this value the name
TCPIPPortCompatibility and press Enter.
The default data value of
this entry is "1". The value "0" is automatically assigned when you create the
new DWORD entry. This is the correct value to limit pcAnywhere to the registered
ports.
A Scenario
You are a remote user and you have
three hosts behind a WinRoute firewall that you need to connect to. Each of
those hosts operates on a different set of ports. In this example, the hosts are
StationA, StationB, and StationC.
To connect to these
hosts, you need to create three .reg files - one for each set of ports. In this
example, these files are StationA.reg, StationB.reg, and StationC.reg.
To
connect to StationA, double-click the StationA.reg file. If you do this on a
Windows 98 computer, you will be prompted with the following dialog
box:
Click
yes.
NOTE: Windows 95 and Windows NT 4.0 do not prompt you. They
import the registry file immediately.
When your data is entered into the
registry, you see the following:
pcAnywhere on the remote will now connect to any host
operating on the ports 5631/5632.
When you need to connect to your host
on StationB, you will have to double-click the StationB.reg file to change your
remote to connect to any host operating on the ports 5641/5642. The same applies
to connecting to StationC.
REMEMBER: Ports 5631/5632 are the
standard pcAnywhere IP ports. Always keep a .reg file to restore you to those
ports.
How to determine hexadecimal values Hexadecimal is a 16
based counting system. In the decimal system, we count from 0 (zero) to 9, in
the hexadecimal system, we count from 0 (zero) to F. (0, 1, 2, 3, 4, 5, 6, 7, 8,
9, A, B, C, D, E, F).
To convert a decimal value to hexadecimal:
1. Click Start, point to Programs, point to Accessories, and then click
Calculator. 2. Click View, and then click Scientific. 3. Click the
Decimal radio button. 4. Type the decimal value of the port you want to
use. For example, 5631. 5. Click the Hexadecimal radio button. The value is
converted. In this case, 5631 is converted to 15FF h. (The "h" indicates that
the value is in hexadecimal format, though this is not needed in the
registry). 6. Close the Calculator.
