What does WhatRoute Do?
Trace Internet Paths
The program is designed to find the names of all the routers
through which an IP packet passes on the way from your Macintosh to
the destination host. In addition it measures the round-trip time
from your Macintosh to the router thus enabling you to determine slow
links (hops) in the Internet. It can also find dead links - ie
routers that don't respond etc etc. If you have access to a UNIX
machine you should read the man page that accompanies
PING Remote Hosts
WhatRoute will PING remote hosts. In this function a small packet
is sent to a remote host and then the time taken for a reply to be
received is recorded.
The DNS Query function is borrowed from the BIND software. The
results of DNS Query show all the DNS Resource Records associated
with an Internet host or domain. The explanation of this stuff is the
beyond the scope of this document and for further information, I
recommend the O'Reilly book, DNS and BIND.
Popup menus give you the choice of Query Class and Query Type. The
different record types are discussed in detail in DNS and BIND
You can also query alternate servers to those specified in your
TCP/IP control panel. This uses the BIND 4.9.5 resolver and is
seperately configured in the DNS Options dialog. The setup is
identical to that required on a UNIX system but is also very similar
to the configuration in your Open Transport TCP/IP control panel.
DNS Query is the only function in WhatRoute that uses the BIND
resolver. All other functions use the settings from your TCP/IP
WhatRoute includes a Finger client. This enables you to
find information about users logged in to other hosts, providing that
host is running a Finger server. A lot of system administrators
consider this to be a security risk, so you may not find this command
to be particularly useful.
To use the command, type firstname.lastname@example.org in the text entry
To find all users on a host, type @host.somedomain.com in the text
This command enables you to find out about people, networks etc
who are registered in the InterNic database.
The default server is rs.internic.net
To get a full list of instructions, clear the text entry field and
click the Whois button. This will list the Help file from the
Whois server running on rs.internic.net
If you wish to use an alternate server, type @host.somedomain.com
after the Whois command
WhatRoute can be configured as a TELNET server. This enables you
to log into your Macintosh from a remote machine and execute
traceroute, ping and dnsquery commands.
