IP Polling
“Polling” refers to Proxy’s process of searching the network for host PCs. When
Proxy searches for IP-based workstations it allows you to select one or more
broadcast addresses in one of the following ways:
Š
<Local Network>— searches your local subnet based on a standard IP
broadcast. This type of poll may only work on a local segment, and
results may vary based on your particular IP stack implementation.
<Local Network> is always available in the broadcast address list. Each
time you bring up the Connect dialog, Proxy automatically performs a
<Local Network> poll (if this feature is set in the Preferences dialog).
Š
IP Broadcast address — searches for a host PC on a specific IP address
in dot notation form a.b.c.d. For example, 198.186.160.55 would search
for a host PC by sending a packet to the address 198.186.160.55 only.
Š
IP Scan address range — searches for a host PC on a range of IP
addresses in dot notation form a.b.c.d(e). For example,
198.186.160.5(99) would scan all addresses starting at 198.186.160.5 for
99 addresses.
Š
Symbolic DNS name — searches for a host PC using a symbolic DNS
name. For example, machine.company.com, would first do a DNS
lookup on the name machine.company.com, then send a packet to its IP
address.
Depending on how much of the network you choose to poll, your search for IP-
based workstations could take anywhere from a couple of seconds to much
longer. A status bar in the Connect dialog shows your polling progress; if need
be, you can choose
Stop Poll to stop your search.
Adding a Broadcast Address
To add an address to the Broadcast Address list:
1 Click
Insert
to bring up the Add/Edit Broadcast Address dialog box,
then click the Broadcast to address button.
2 Enter a valid IP broadcast address or DNS name in the Address field.
3 Enter an optional description string in the Description field.
4 Click
OK
.
Your address will now appear in the Broadcast address list. If you
entered a DNS name, the Address field will be set to its IP address, and if
you have not entered a Description that field will contain the DNS name.
