How can I use Telnet to access
a news server?
|
Most of us use a news client (e.g., Outlook Express) to access
public newsgroups. However, the Network News Transfer Protocol
(NNTP) used for newsgroups is quite simple, and you can access
a news server from a Telnet client by specifying port 119. For
example, from the command prompt, type
C:\> telnet msnews.microsoft.com 119
You'll be greeted with a prompt specifying the NNTP service
version--for example,
200 NNTP Service 5.00.0984 Version: 5.0.2195.4386 Posting Allowed
You can use several commands to control the newsgroup Telnet
session. The available commands include
- LIST--Displays a list of all newsgroups on the server. The
output will show the group name, the last article ID, the
first article ID, and an indicator to specify whether you
can post to the newsgroup.
- GROUP --Moves to a particular group.
- HEAD --Displays the header of a specified article
(if you don't specify an article ID, the command uses the
current article and selects the first article in the group
upon moving to a group).
- BODY --Displays the body of a specified article.
- ARTICLE --Displays the header and body of a specified
article.
- NEXT--Moves to the next article.
- LAST--Moves to the previous article.
- HELP--Provides Help from the news server.
- POST--Posts a new article to the group. You must include
the following information:
post
From: <your email address>
Newsgroups: <newsgroup name (e.g., microsoft.test)>
Subject: <subject>
<message text>
.
You must enter a period (.) on a blank line to finish.
- QUIT--Exits the news server.
How do I assign multipled IP
addresses to a single NIC?
|
It is possible to assign more than one IP address to a single
NIC (Network Interface Card). To configure extra IP addresses
under NT 4.0 perform the following:
- Right click on Network Neighborhood and select Properties
(if you are unable to do this start the Network Control
Panel applet via control panel)
- Select the Protocols tab
- Select 'TCP/IP Protocol' and click the Properties button
- Select the 'IP Address' tab and you will see your normal
IP address. Click the Advanced button at the bottom of the
dialog
- Select the Adapted and click Add under the IP addresses
section
- Enter the new IP address and subnet mask. Click Add
- Click OK to the advanced dialog
- Click Apply then OK to the TCP/IP dialog
- Close all other dialogs
- Reboot the computer
Under Windows 2000 the procedure is the same except to get
the TCP/IP protocol properties you need to:
- Right click on "My Network Places" and select Properties
- Right click on "Local Area Connection" and select Properties
- Select "Internet Protocol (TCP/IP) and select Properties
- The procedure is then as above except the reboot is not
necessary
How do I enable IP forwarding
in Windows 2000?
|
In Windows NT 4.0, you enable IP forwarding by checking "Enable
IP Routing" in the Advanced TCP/IP configuration dialog box.
However, to enable a multihomed Win2K box to act as an IP
router, you must perform the following steps:
- Start regedit.exe.
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\Tcpip\Parameters.
- Double-click IPEnableRouter.
- Set the value to 1. Click OK.
- Close regedit.
- Reboot the machine.
