The
NetworkTestTool is a TCP/IP based tool to verify the network
connectivity between the various CommCell components. It also enables you
to troubleshoot network connectivity and data transmission between any two
CommCell computers. It provides a single point interface to all basic network tests.
The NetworkTestTool can be used in the following modes:
If you are using a MAC computer, run the following
command before running the NetworkTestTool:
Utility mode provides options to ping, verify and troubleshoot network
connectivity. In this mode the tool supports several options like
lookup,
cvping and service check. The following sections
explain the various options:
Lookup
Lookup option enables you to run a command to perform a turnaround name lookup of the
specified host using a specified IP version. It performs a DNS (Domain Name
Server) lookup for the host name in the network before trying to establish a
TCP/IP connection.
To
perform lookup:
From the command prompt, give the path i.e.<software
installation path>\Base> folder and run the command using the
syntax below:
CVPing option enables you to troubleshoot and test the network connectivity
between two clients. You can test the network connectivity
between various resources of a network by establishing
TCP/IP connection to the destination computer. The CVPing performs a name lookup
check and pings the IP address of the destination computer to check the network
connectivity.
To
check network connectivity:
From the command prompt, give the path i.e.<software
installation path>\Base> folder and run the command using the
syntax below:
The network connectivity is verified,
and the result is displayed.
Service Check
Service check utility enables you to gather basic network information
regarding application specific services. If you have more
than one instance then you will have to specify the instance name you wish to verify.
Also, ensure that the destination computer is registered with the CommServe
where you are running the tool from.
To
check network connectivity:
From the command prompt, give the path i.e. <software installation path>\Base
folder and run the command using the syntax below:
servicecheck - Option to use service
check for network verification.
Log - The location of the log file.
The location must be specified when providing the command.
HostName - Host name of the
destination computer.
UseIPv4/UseIPv6/UseIPAny - The
protocol used for network communication. The default protocol is IPv4.
HostIP <IPAddr> - The
destination computer's IP Address. The default IP address is Local host.
If you provided the host name of the destination computer, the
HostIP is not needed.
Instance <InstanceName> -
The instance name of the destination computer. The default instance is Instance001.
Platform <RemotePlatformType>
- Type of the remote platform (CommServe, MediaAgent and the CommCell
Console modules.) All the platforms are checked by default.
When executed in the server mode the server listens to an incoming client
connection. You can specify the port for listening and the TCP/IP protocol version to
be used. Once the connection is established with the
client, the connectivity is verified. The following section explains the various
options and their usage.
To
check network connectivity using NetworkTestTool from Server computer:
From the command prompt, navigate to the <software
installation path\Base> folder and run the command using the syntax
below:
Server -
Option to run network check from server computer.
log <location> - The location
of the log file. The location must be specified when providing the
command.
SrvPort <PortNum> - The port
number of Server. The default port number is 25000.
UseIPv4/UseIPv6/UseIPAny - The
protocol used for network communication. The default protocol is IPv4.
BindIP <IP Address> - If the client computer has multiple NICs,
specify IP address to which the tool will bind. If you do not specify
any IP address, the tool will bind to the IP address specified using the
sBindToInterface registry key on the client. If this registry key is
not created on the client, the tool will bind to all NICs on the client.
Instance <Instance Name> - If the client computer has multiple
instances of Calypso, specify any one instance name. The
tool will use this instance to check the connectivity.
When executed in the client mode, the client attempts to connect to the
server. Once the connection is established, after the initial handshake the
client sends buffer(s) to the server to verify the data transmission. You can
specify parameters like the port and the TCP/IP protocol to be used for the connection.
You can also specify parameters for the data transmission such as the buffer
count and the delay between transmitting the buffers. The following section
provides the various options and their usage.
The server and client modes work in conjunction.
To
check network connectivity using NetworkTestTool from Client computer:
From the command prompt, navigate to the <software installation path\Base>
folder and run the command using the syntax below:
Client - Option to run network check from
client computer.
log <location> - The location
of the log file. The location must be specified when providing the
command.
SrvHostName <HostName> - Host
name of the Server.
SrvHostIP <IPAddr> - IP
Address of the Server. The default IP address is Local host. If you
provided the host name of the server, the
SrvHostIP is not needed.
SrvPort <PortNum> - The port
number of Server. The default port number is 25000.
UseIPv4/UseIPv6/UseIPAny - The
protocol used for network communication. The default protocol is IPv4.
BindIP <IP Address> - If the client computer has multiple NICs,
specify IP address to which the tool will bind. If you don not specify
any IP address, the tool will bind to the IP address specified using the
sBindToInterface registry key on the client. If this registry key is
not created on the client, the tool will bind to all NICs on the client.
Instance <Instance Name> - If the client computer has multiple
instances of Calypso, specify any one instance name. The
tool will use this instance to check the connectivity.
FirstBufferDelay <Delay> - Number
of seconds to delay before sending/receiving first buffer. The default
value is 0.
InterBufferDelay <Delay> - Number
of milli-seconds to delay before sending/receiving each buffer.
The default value is 0.
BuffsizeClientToServer <BufSize> -
The size of the buffer (Bytes) to transmit from client to server.
The default size is 16 KB.
BuffsizeServerToClient <BufSize> -
The size of the buffer (Bytes) to transmit from server to client.
The default size is 16 KB.
BufferCount <count> - Number of buffers of random data to
be sent/received to/from the server. The default value is 0.
PortServer <PortNum> - The port
Server on which test should be run. The default value is 25001.
PortClient <PortNum> - The port
Client on which test should be run. The default value is 25002.
The ChangeNetworkPwd tool allows you to change the network password of one
ore more clients
with a stronger password in order to increase the security of your network.
Follow the steps below to update the network password:
On the CommServe computer, open the command line window and provide the path to the <software
installation path>\Base> folder.
Execute the following command using the
syntax below:
listAllWeak - Option to list all the
clients that need a stronger password.
updateAllWeak - Option to update all the
clients in the CommServe that need a stronger password.
<clientName> - The name of the client on
which the password will be updated.
vm <InstanceName> - The name of the
instance where the CommServe is running. If the instance is not specified,
Instance001 is used.
For example, the following command will update the password for client1.
ChangeNetworkPwd client1 -vm instance002
The password is updated for the client(s). To verify the success of this
command, navigate to the <software installation
path>\Log Files folder and review the
ChangeNetworkPwd.log file.
