-
- Introduction
- ------------
-
- SmoothWall is a self-contained, stripped down Linux distribution for providing
- Internet access via modem, ISDN, and cable to a LAN. Currently it only
- supports modems, however) Web pages configure PPP, etc. It runs on a 386 with
- 8meg and up. No prior knowledge is required to use SmoothWall. Access to the
- Internet from the LAN is through IP masquarade.
-
- Once installed, SmoothWall is configured via a number of webpages, such as the
- page for configuring PPP, and the page for setting passwords. The main page
- features buttons for triggering a dial attempt, and hanging up the link. Status
- info, such as the state of the PPP link, including how long the link has been
- active for, is also displayed here. All configuration can be performed via the
- web frontend.
-
- Telnet and ftp access can also be enabled or disabled, should either be
- needed. In a nomral installation, noone need even know they are there.
- tcp_wrappers prevents connections from the Internet. No services are available
- from the external interface.
-
- SmoothWall differes from single-floppydisk approaces to the problem of Internet
- access for a LAN in that it is an expandable "appliance". Because it runs
- apache, it can be made extremely easy to configure. Because it is installed
- onto a harddisk, full logging can be done and much more space is available to
- support more hardware.
-
- The base system files are from VA-Linux 6.2.1 (which is more or less RedHat 6.2)
-
- Features
- --------
-
- * PPP Dial on Request dialing. Dial and Hangup is controlled via a webpage.
- The buttons are password protected.
-
- * Application helpers, including: ftp, irc and icq. These enable those
- application to operate fully across the masquaraded link.
-
- * IPChains firewall. Full firewalling of the Internet link, with anti-spoofing.
-
- * DNS proxy cache (dnrd).
-
- * DHCP server.
-
- * Remote shutdown feature.
-
- * Network traffic graphs (ipac).
-
- * Fully configurable via any browser capable of showing tables. Includes pages
- for viewing system and firewall logs.
-
- * Telnet access for those who need to make custom changes.
-
- * Upto 5 ISP profiles.
-
- * SSH server.
-
- Hardware requirements
- ---------------------
-
- 386 with 8meg. Lowest spec so far tested is a 486DX4 with 32meg. Should
- easily run on a DX2 with 8meg. Any 2.2.16 suppored network card. Modem,
- internal (NOT WinModems) or external. 100meg of IDE harddisk. An IDE CDROM.
- Alternativly, the common "old style" CDROM interfaces are supported, such as the
- oundBlaster ones. Only the SB16 driver has been tested, but the others should
- all work. You will probably need to supply IO/IRQ information.
-
- Installation
- ------------
-
- The CDROM is bootable. If you are installing onto a machine which lacks
- bootable CDROM support, you will need to create the bootdisk. Use dd to write
- the image to a floppy:
-
- dd if=/path/to/cdrom/smoothwall-disk1-X.Y.Z of=/dev/fd0 bs=1k count=1440
-
- Now you can boot from that floppy disk and proceed as per a CDROM install.
-
- If the machine lacks a CDROM drive, you may also install via a ftp or webserver,
- which has made the smoothwall files available for download by the machine you
- are installing onto. To do this, first write the disk2 image to a second floppy
- disk, as you did for disk1. Then copy the smoothwall.tgz to somewhere in your
- web or ftp server. Finally, when asked to choose the installation method choose
- HTTP or FTP. You will be asked to insert disk2 (it contains the network
- drivers) and after configuring the network, you will need to supply a URL to the
- smoothwall.tgz file. The file will then be downloaded to a temporary place
- before being installed, as per a normal CDROM install.
-
- Currently network card detection is non existant, so you will need to supply the
- Linux module name, and any optional module parameters. Generally, PCI hardware
- is alot easier to setup then ISA.
-
- Example cards and modules:
-
- NE2000 (or clone), ISA, on IO address 0x300 ne io=0x300
- NE2000 (or clone), PCI ne2k-pci
- Intel EtherExpress Pro 100 eepro100
-
- After the files have been copied onto the harddisk, you will need to supply two
- passwords. One is the Linux "root" password. This is the password you need if
- you wish to login, either at the console or via telnet. As installed,
- SmoothWall has only one user account, root. The second password is the
- SmoothWall "admin" password. This is the password that is needed to configure
- ppp, the DHCP server, etc. After setting up the passwords, the harddisk will be
- made bootable, and the machine will reboot.
-
- Configuring
- -----------
-
- Upon rebooting, the keyboard can be used to login directly to a Bash shell. Go
- to another machine and point the web browser at:
-
- http://(SmoothWall IP or hostname)
-
- SmoothWall has two "web users". The first, called "admin", is the one for
- configuring SmoothWall. This is needed for: configuring PPP, configuring DHCP,
- and enabling telnet/ftp, and viewing the logs. The other user is called "dial"
- and is able only to dial and hangup the link.
-
- PPP setup
-
- Probably the first thing you will to do is configure PPP. Click the PPP setup
- link (you will have to supply the admin username and password) and enter the PPP
- details. Click the Save button before returning to the main page. You should
- now be able to dial the link up and get a connection. When the link is
- established the SmoothWall machine will beep. It will beep twice when the link
- goes down. See "Configuring desktops" for a brief explanation of how to
- configure Linux and Windows desktops to access the Internet through the
- SmoothWall box.
-
- Change passwords
-
- On this page you can change the "admin" and the "dial" passwords.
-
- Remote access
-
- You can enable or disable telnet or ftp access here. Click Save to activate the
- changes. Both are disabled as per default.
-
- DHCP configuration
-
- SmoothWall may optionally run a DHCP server, easily capable of configuring
- dozens of desktop machines within its subnet. In the DHCP configuration page
- you will see boxes for entering a start and end address range. This is the
- range over which the DHCP server will give machines which ask for an address, so
- no other machines (eg. servers) should use this range. Two DNS server address
- can also be specified. This will be the address the DHCP server gives the
- desktops to use as their DNS servers of choice. Because SmoothWall runs a DNS
- proxy, the default is to use the SmoothWall box itself. If you run a local DNS
- on your network, specify it as the Secondary DNS. The two lease time fileds can
- almost certainly be left alone, but are available for people who have special
- requirements. You must enable the DHCP server by ticking the Enable box if you
- want to use it. Click Save to start (or stop) the DHCP server. It will be
- started again automatically when SmoothWall reboots.
-
- The default gateway that the DHCP server is fixed to point back to the
- SmoothWall box.
-
- Shutdown control
-
- This page contains a single button labeled Shutdown that can be used for, you
- guess it, remotely shuting down SmoothWall. After the shutdown process has
- finished, you will hear a beep. You can then disconnect the power.
-
- Log viewer
-
- This page lets you view three types of logs: PPP logs, DHCP logs and kernel
- logs. The PPP log is useful for diagnosing PPP connection problems.
-
- Firewall log viewer
-
- Here you can see the IPChains logs in a nice tabular format. Every packet
- logged is a denied packet.
-
- Status information
-
- This page is available to everyone, even people without the dial password. It
- shows basic system information, such as memory usage and network interface
- information. It also displays a list of services and wether or not they are
- currently running.
-
- Network traffic graphs
-
- Four graphs show network traffic on the ethernet and the Internet link, in
- incoming and outgoing directions. The graph is updated every half an hour.
-
- Configuring desktops
- --------------------
-
- If you are using the DHCP server, it is simply a matter of telling the operating
- system to obtain an address via DHCP. If not, then the machine will need an IP
- address, DNS server, and a default gateway. The first is up to you. The DNS
- and default gateway should both be set to the SmoothWall IP address.
