Because many other security applications use PHP, this product may allow you to apply skills you have already learned. #Firewall builder use telnet vs ssh portablePHP Ipchains project () The primary strength of this product is that it is based on PHP, which is a truly portable language, and is well supported by Apache Server. Its "secure logging" feature will employ encryption so that the firewall can log to remote systems without the fear of sniffing attacks. NetFilter-1 () If it lives up to its promise, this particular project could produce a truly useful piece of software, because it is trying to mimic the Check Point Firewall-1 product. Heimdall Linuxconf Firewall () A promising effort, mainly because it proposes to be an add-on to the Linuxconf application. Jb dynFW () This project appears to be interested in creating a personal firewall product, as opposed to a multihomed firewall. The following is a partial list of applications being developed at the current time: #Firewall builder use telnet vs ssh how toGenerally, this time could be better spent learning how to use Iptables or Ipchains commands. Consequently, you may have to spend a great deal of time configuring your window manager. #Firewall builder use telnet vs ssh upgradeThe more advanced GUI applications often require you to upgrade to either the very latest version of a particular window manager, such as KDE or Gnome, or to use an idiosyncratic version or configuration. Although some, such as Mason, are quite impressive, limitations still persist: As of this writing, Mason does not support Iptables. Most of these applications are still in beta form, so remember that they often provide limited functionality. #Firewall builder use telnet vs ssh codeIf you cannot review the source code yourself, then employ someone to check it, especially if you plan to use it in an enterprise environment. Often, these downloads do not provide public keys or hash values for their code therefore, before using any of the applications, make sure that you review the source code. Weighing the Benefits of a Graphical Firewall UtilityĪs you consider using any of the GUI applications covered in this section, keep in mind the following issues: Įas圜hains Eas圜hains has a ncurses-based GUI, and supports Ipchains and Iptables. It is also quite unstable on most versions of Red Hat Linux through version 7.1. It allows you to create rules for multiple interfaces, networks, and hosts. įirewall Builder Firewall Builder is in many ways the most ambitious open-source GUI tool. Although it purports to be stable, it appears to have problems working with common versions of KDE. Knetfilter A GUI firewall designed to work with the KDE desktop environment. Do not confuse this product with the HTML Mason utilities meant to dynamically generate HTML for Apache Server. In spite of this, Mason's approach to rules creation is both unique and sound, as it attempts to create rules based on your network traffic about your firewall needs. As of this writing, Mason does not support Iptables. Mason A unique product, Mason is designed to first listen in on traffic passing through your firewall, and then generate Ipchains or ipfwadm (the precursor to ipchains and Iptables) rules. Although Firestarter does support multiple interfaces, it, like most of the open-source GUI firewall applications, is best used only as a beginning to a firewall on a multihomed system. You may need to adjust some of these automatic settings. Like many automated firewalls, it creates multiple rules to filter out known and expected attacks. It can be used to create a personal firewall, but also supports multihomed systems. The more effective firewall scripts and GUI tools include the following:įirestarter A fairly sophisticated graphical tool that supports both Ipchains and Iptables. Many of these utilities are quite useful, although they are mostly effective in beginning your firewall configuration you will likely have to customize the rules these applications generate. Similarly, developers are also busy creating GUI applications that make the job easier. Several attempts have been made to automate the process of creating a firewall in Linux.
