It -performs two different functions: -<ul> -<li>TkPPPoE lets you <em>define</em> connection properties. This step must -be done as root. -<li>TkPPPoE lets you <em>start and stop</em> PPPoE connections. This step -may be done as a normal user, depending on how you configured the connection. -</ul> - -<h1>Defining Connections</h1> - -To define connections, start TkPPPoE as root. You can do this from -a terminal by typing <code>tkpppoe</code>, or from the KDE or GNOME menus -by selecting <b>Internet : TkPPPoE</b>. The following window pops up: - -<p> -<center><img src="mainwin.png" width="361" height="73" alt="Main Window"> -</center> - -<p> -Because you have not yet defined any connections, the connection property -window also pops up: - -<p> -<center><img src="props-basic.png" width="440" height="259" alt="Connection Properties - Basic"> -</center> - -You can pop up the connection property window at any time by clicking -<b>New Connection...</b> You can edit the properties of an existing -connection by selecting the connection's name and clicking -<b>Properties...</b> -<h4>Basic Information</h4> - -Let's fill in the basic information: -<ul> -<li>For <b>Connection Name</b>, enter a unique name for this connection. It -can be anything you like, but must contain only letters, numbers, underscores -or dashes. In particular, it can't contain spaces. If you have only one -PPPoE connection, a good name is <b>Default</b>. -<li>For <b>User Name</b>, enter the user name supplied by your ISP. Enter -only the user name; do not enter an "@isp.com" part. -<li>For <b>Network</b>, you may have to enter your ISP's domain name. -(For example, <b>isp.com</b>.) Some DSL providers add this to your user -name; others do not. You may have to experiment a bit. The two most likely -choices are your ISP's domain name, or blank. Try both. -<li>For <b>Password</b>, enter the password your ISP provided you with. -</ul> - -<h4>NIC and DNS</h4> -Click on the <b>NIC and DNS</b> tab: - -<p> -<center><img src="props-nic.png" width="440" height="259" alt="Connection Properties - NIC and DNS"></center> -<p> -<ul> -<li>For <b>Ethernet Interface</b>, enter the Ethernet interface connected -to the DSL modem. It is something like <b>eth0</b> or <b>eth1</b>. Click -on <b>...</b> to browse a list of detected Ethernet interfaces. -<li>For <b>DNS Setup</b>, you have three options: -<ol> -<li><b>From Server</b> means that the system will obtain DNS information from -the PPPoE server. This is the correct choice for most ISPs. -<li><b>Specify</b> means that you will enter the IP addresses of your DNS -servers manually. In this case, enter the addresses in the <b>Primary DNS</b> -and <b>Secondary DNS</b> entries. -<li><b>Do not Adjust</b> means that you want RP-PPPoE to leave your -DNS setup alone. Use this if you are running your own caching DNS server -or know that you don't want the DNS setup touched. -</ol> -</ul> - -<h4>Options</h4> -Click on the <b>Options</b> tab: - -<p> -<center><img src="props-options.png" width="440" height="259" alt="Connection Properties - Options"></center> -<p> -<ul> -<li>If you want ordinary users to be able to start and stop this connection, -enable <b>Allow use by non-root users</b>. If you do not enable this, -non-root users will be able to monitor the connection, but not control it. -<li>If you want to use synchronous PPP, enable <b>Use synchronous PPP</b>. -This is recommended as it conserves CPU usage, but may not work on some -(misconfigured) Linux kernels. -<li>For <b>Firewalling</b>, you have three options: -<ol> -<li><b>Stand-Alone</b> installs a simple firewall ruleset for stand-alone -machines. Use this if you have only a single computer connected to the DSL -modem. -<li><b>Masquerading</b> installs a simple firewall ruleset for using -your Linux computer as an Internet sharing device. If you have two Ethernet -cards, you can connect one card to the DSL modem and the other to an -internal LAN. The masquerading firewall ruleset lets internal machines -share the DSL connection. -<li><b>None</b>. If you already have your own firewall rules, or you wish -to run servers on your machine, select None. This is <em>not recommended</em> -unless you take steps to secure your machine, and know what you are doing. -</ol> -</ul> - -<h4>Advanced</h4> -Click on the <b>Advanced</b> tab: - -<p> -<center><img src="props-advanced.png" width="440" height="259" alt="Connection Properties - Advanced"></center> -<p> - -In most cases, you can leave <b>AC-Name</b> and <b>Service-Name</b> blank. -In some cases, your ISP may require you to enter information in these fields; -contact your ISP for more information. - -<h1>Controlling Connections</h1> -For these examples, run <code>tkpppoe</code> as a normal user (not root). -The main window appears like this: - -<p> -<center><img src="mainwin-nonroot.png" width="206" height="73" alt="Main Window - Non-root"> -</center> -<p> -<ul> -<li>To start a connection, press <b>Start</b>. The two LEDs flash red -and grey. If the connection is established, they turn green. -<li>To stop a connection, press <b>Stop</b>. -</ul> - -<p>The two rectangles to the right of the connection name are the -<em>status LEDs</em>. The top LED corresponds to transmitted data and -the bottom to received. The LEDs are colored as follows: -<ul> -<li>Grey -- connection is not established. -<li>Flashing red/grey -- connection is being started. -<li>Green -- connection is up, but idle. -<li>Yellow -- connection is up and data is being sent or received. -<li>Red -- connection has been lost, but the system is trying to reestablish it. -</ul> - -<p> -When a connection is established, two graphs appear: - -<p> -<center><img src="mainwin-busy.png" width="206" height="73" alt="Main Window - Established Connection"> -</center> -<p> - -The left (red) graph shows transmitted packets and the average -transmission speed (in bits per second) over the sample time. The -right (green) graph shows received packets. - -<h1>Miscellaneous Information</h1> -<ul> -<li>The connection menu has an entry called <b>User's Manual</b> which -will pop up this user manual (if you have Netscape installed.) -<li>You can define multiple PPPoE connections, but you should not use -more than one simultaneuously unless you feel comfortable editing scripts -and setting up routing tables. By default, TkPPPoE tries to add a default -route for connections. This does not work well with multiple simultaneous -connections. -<li>If you exit from TkPPPoE, connections which are up remain up. You -have to explicitly stop connections if you want them terminated. -</ul> -<hr> -<a href="http://www.roaringpenguin.com/pppoe/">TkPPPoE</a> is Copyright 2001 by <a href="http://www.roaringpenguin.com">Roaring Penguin Software Inc</a> and -is licensed under the GNU General Public License. -<p>Screenshots show TkPPPoE running under the <a href="http://www.xfce.org">XFCE</a> desktop, a lightweight UNIX and Linux desktop. -</body> -</html> diff --git a/mdk-stage1/rp-pppoe/gui/pppoe-wrapper.1 b/mdk-stage1/rp-pppoe/gui/pppoe-wrapper.1 deleted file mode 100644 index 4fbf2bce2..000000000 --- a/mdk-stage1/rp-pppoe/gui/pppoe-wrapper.1 +++ /dev/null @@ -1,45 +0,0 @@ -.\" $Id$ -.TH PPPOE-WRAPPER 1 "26 February 2001" -.UC 4 -.SH NAME -pppoe-wrapper \- SUID wrapper for starting and stopping PPPoE connections. -.SH SYNOPSIS -.B pppoe-wrapper start linkname -.P -.B pppoe-wrapper stop linkname -.P -.B pppoe-wrapper status linkname - -.SH DESCRIPTION -\fBpppoe-wrapper\fR is a small SUID program which allows non-root users -to start and stop PPPoE links.
