Syntax
object.Execute( [RemoteHost],
[RemotePort], [UserName], [Password],
[Command], [Timeout], [Options] )
Parameters
- RemoteHost
- A optional string argument which specifies the name of the
server to connect to. The string may either be an IP address or a
fully qualified domain name. If the argument is omitted, the value
of the HostAddress or HostName property will be
used.
- RemotePort
- An optional integer argument which specifies the port number to
connect to. This method may be used to either connect to the rexec
service or the rshell service, and which service is selected
depends on the port number provided. If this argument is omitted,
the value of the RemotePort property will be used.
| Value |
Description |
| rshPortExec |
A connection is established with the server using port 512,
the rexec service. This service requires that the client
provide a username and password to execute the specified
command. |
| rshPortRshell |
A connection is established with the server using port 514,
the rshell service. This service uses host equivalence to
authenticate the user. With host equivalence, the server
considers the client to be equivalent to itself, and as long as
the specified user exists on the server, the client is
permitted to execute commands on behalf of the user without
requiring a password. Host equivalence is configured by the
server administrator. |
- UserName
- An optional string argument which specifies the username which
used to authenticate the client session. If this argument is
omitted, the value of the UserName property will be
used.
- Password
- An optional string argument which specifies the password to be
used to authenticate the user. If this argument is omitted, the
value of the Password property will be used. A password is
only used if the client is connecting to the rexec service. The
rshell service uses host equivalence to authenticate the user and
this argument will be ignored.
- Command
- An optional string argument which specifies the command to be
executed on the server. If this argument is omitted, the value of
the Command property will be used.
- Timeout
- An optional integer argument which specifies the number of
seconds that the client will wait for a response from the server.
If this argument is omitted, the value of the Timeout
property will be used. This value is only used for synchronous
connections where the Blocking property is set to True.
- Options
- An optional integer argument which specifies one or more
connection options. This argument is reserved for future use and
should be omitted.
Return Value
A value of zero is returned if the operation was successful,
otherwise a non-zero error code is returned which indicates the cause
of the failure.
Remarks
The Execute method executes the specified command on a
server. Output from the command may be read using the
Read method. Input can be supplied to the program using the
Write method. To search for a specific sequence of bytes in
the output returned by the server, use the Search method.
