What is OTTool?
OTTool is a free utility which provides a synopsis of the AppleTalk and IP
configuration parameters within Apple Computer's Open Transport networking
architecture. In addition, OTTool allows users on IP networks to make
Domain Name Server (DNS) queries, ping devices using ICMP Pings, trace
IP routes (UNIX traceroute), scan through ranges of IP addresses asking
for resolutions, and to query a DNS for Mail Exchange and System Info. On
MacOS PowerPC machines, it will also dump the IP ARP cache. We would
like to hear your suggestions and comments regarding the software. Please
send your feedback to firstname.lastname@example.org.
What changed in OTTool since version 1.0ß4?
We received a lot of suggestions for improving OTTool from users. With
version 1.0, we
* added IP ARP cache display
* added Balloon Help throughout the application
* added smart zooming of all windows
* fixed some minor bugs, including incorrect pinging of non-existent nodes
Thanks for the suggestions, and keep them coming!
AppleTalk and IP Configuration Parameters
When launched, OTTool gathers the AppleTalk and IP network configuration
parameters from your Macintosh and displays them in the OTTool window. The
AppleTalk parameters are on the left side of the window and the IP
parameters are on the right. The following network information is retrieved:
ICMP Ping dialog
At the top of the ICMP Ping dialog is a set of three editable parameters
contained within the following sentence: "Send [A] packets with [B]
second(s) interpacket delay waiting no more than [C] second(s) for a
reply." [A] is the number of ICMP packets to send to the device,
[B] is the number of seconds between each packet that is sent, and [C] is the
number of seconds that OTTool should wait before considering a packet
Once you have set variables A, B, and C to your liking,
click the Start
button to begin pinging the device. As OTTool is pinging the device, the
following real time information is displayed in the lower portion of the
ICMP Ping dialog:
OTTool implements UNIX traceroute functionality. After typing an IP
address or domain name, press the Trace button. This will cause the
TraceRoute window to be displayed. Each IP router through which data
to the selected IP address or domain name will be displayed preceded
by a hop count. For each hop, OTTool sends three packets, so up to three
IP addresses (one for each router) may appear for each hop. After the
trace has completed, double-clicking on any displayed address will
bring up the OTTool Ping dialog, and ICMP pinging will commence,
as described above. Also, to copy a domain name (if available) or an
IP address from the TraceRoute window to the scrapbook, select the
domain name or IP address, and select Copy from the Edit menu.
Scan Address window
OTTool allows domain name resolutions to be made for a range of
IP addresses. After typing an IP address or domain name, press the
Scan button. This will cause the Scan Addresses window to be
displayed. IP addresses will appear five at a time, in ascending
order, and a reverse DNS query will be made for their domain name.
To query for domain names in descending order, hold down the Option
key and press the Scan button. Scanning IP addresses is a good way to
test domain name servers and to explore Internet sites. To cancel
the scanning process, press the Apple key and period, at the same
time. After the scan has completed, double-clicking on any displayed
address will bring up the OTTool Ping dialog, and ICMP pinging will
commence, as described above. Also, to copy a domain name (if
available) or an IP address from the Scan Address window to the
scrapbook, select the domain name or IP address, and select Copy
from the Edit menu.
Mail Exchange/SysInfo dialog
OTTool allows queries of Domain Name Servers for standard
Mail Exchange and System Information for a given domain name.
After typing an IP address or domain name, press the MX button.
This will cause the Mail Exchange/SysInfo dialog to be displayed.
Note that this information may not be available for the domain
name selected as not all Domain Name Servers have been configured
with this information.
ARP Cache window
For MacOS machines equipped with a PowerPC, OTTool will display
the ARP cache. The ARP cache is maintained by Open Transport and
is used to map IP addresses to hardware addresses. For example, on
Ethernet networks the ARP cache will contain mappings from IP
addresses to Ethernet addresses. This information is useful for
such applications as identifying Ethernet hardware when examining
Ethernet protocol analyzer output. Choose ARP Cache from the
Windows menu, then click Refresh in the ARP Cache window to
query Open Transport for the ARP Cache contents. Click Refresh in
order to display the ARP Cache at any given point in time.
