Learn Windows XP Professional: Troubleshooting TCP/IP – Part 2 (Page 4) Page 4

RSH – RSH is a TCP/IP utility that enables clients to
run commands directly on remote hosts running the RSH
service without having to log on to the remote host. RSH is
one of the UNIX r-commands available on all UNIX
systems.

[NOTES FROM THE FIELD] –
Microsoft’s implementation of TCP/IP includes the RSH
client software but not the RSH service. If a user on a
computer running in a Windows domain tries to use RSH to run
a command on a remote UNIX server that is running the RSH
daemon, the domain controller will be required by the RSH client
in order to resolve the username of the user.

REXEC – REXEC runs commands on remote hosts
running the REXEC service and authenticates the user name on
the remote host before executing the specified command.

REXEC host [-l username] [-n] command

• host –
  Specifies the remote host on which to run command.
• -l username –
  Specifies the user name on the remote host.
• -n –
  Redirects the input of REXEC to NULL.
• command –
  Specifies the command to run.

FINGER
– FINGER is a TCP/IP utility used for viewing information
about a user on a system running the finger service.

Typing the command  finger
jason@windowsxp.2000trainers.com  displays information about
user Jason on a server called windowsxp.2000trainers.com.

FINGER
[-l] [user]@host [...]

• -l –
  Displays information in long list format.
• user –
  Specifies the user you want information about. Omit the
  user parameter to display information about all users on
  the specified host.
• @host –
  Specifies the server on the remote system whose users you
  want information about.

[NOTES FROM THE FIELD] –
Microsoft’s implementation of TCP/IP includes the
FINGER client software but not the FINGER service. You are
able to run the FINGER client on a machine running a Windows
operating system that is connected to the Internet in order
to obtain results from a remote UNIX server running the
FINGER daemon as a FINGER gateway.

That’s a
wrap for this week. Be sure to check back in next week for
the next article in this series.

In
the meantime, best of luck in your
studies and please feel free to contact me with any
