* March 7th 2002 Simon Edwards <simon@simonzone.com> - 1.9.12 release - Should work ok with recent autoconf versions now, and will probably work on KDE3 too. (Thanks to Carsten Pfeiffer) - No longer requires that packets creating a NEW tracked connection have thier SYN bit set. It can now pick up previously dropped (tracked) connections. (Blocking !SYN was causing too many log entries and a bit of trouble elsewhere). - Added CDDB, MSN Messenger, VNC and PPTP support. * Feburary 20th 2002 Simon Edwards <simon@simonzone.com> - 1.9.11 release - Bugfix: Now doesn't try to enforce the Strong ES model. Linux 2.2 and 2.4 as it turns out, use the weak model. - Fixed a nasty flaw in the way UDP reply packets were handled. (Thanks to Sander Plomp for noticing this). - Added control over TCP timestamps usage (defaults to off). - Windows Networking (NETBIOS) fixes. - Small SSH fix. - Added support for Telstra's BigPond Cable authentication/heartbeat. - Changed the GUI layout on the Protocol tab. Hopefully it's clearer now. - Additions to the manual. * January 17th 2002 Simon Edwards <simon@simonzone.com> - 1.9.10 release. - A "Restore to factory defaults" button. - Small changes to some of the text strings in the GUI. - Explicitly requests /bin/bash when running the scripts from the GUI. - Additions and improvements to the manual. * December 20th 2001 Simon Edwards <simon@simonzone.com> - 1.9.9 release. - Fixed a small bug in the DHCP rules. (It was blocking lease refreshes on Win). - Fixed ipchains support, looks like it's been broken for a while. - Resetting the network subsystem now handles ipchains or iptables in /usr/sbin/ too. - Added AudioGalaxy and DirectPlay (most Microsoft games), Halflife support. - Fixed a tiny crash bug in the case where the protocol DB file can't be found. - Made the source port usage info in the protocol DB tighter. - Looks for ipchains/iptables in /usr/local/sbin too. * November 29th 2001 Simon Edwards <simon@simonzone.com> - 1.9.8 release. - Added proper multi-language support to the protocol DB. - Fixed a nasty bug in the generated firewall scripts that could cause the machine to appear to hang at boottime. - Fix a small design bug concerning the user defined protocols. (Accepts any source port now, instead of just ones in the dynamic range). - Guarddog now looks for ipchains or iptables in /usr/sbin/. * November 19th 2001 Simon Edwards <simon@simonzone.com> - 1.9.7 release. - The README file has been updated. Please read it. - Firewall script now returns a proper exit code. - Fixed Diablo II protocol entry. (I hope) - Added Microsoft's "SMB over TCP" protocol to the DB. - Added XDMCP to the DB. - The iptables part now only accepts NEW state tracking entries that are SYN packets. - Fixed a buglet where clicking 'Ok' is the firewall disabled didn't exit the program after reseting the network subsystem. - Added DHCP support to the "Advanced" tab. (Thanks to Ludovic Lange for the patch). - Added "Log Aborted TCP connections" option. This can detect half-open stealth scans. (Now every nmap scan type can be logged). - Specifies the log level to iptables as a number. (iptables>=1.2.3 wants a number) - Scripts now explictly use bash instead of just plain sh. (bash is the official standard linux shell anyway). - Fixed NFS support. - Scripts now explicitly use gawk(1) instead of just plain awk(1). - Fixed a problem that would stop the firewall script from working properly for people who use a language setting other than English. (thanks to Ludovic Lange detecting submitting a patch for this). * September 28th 2001 Simon Edwards <simon@simonzone.com> - 1.9.6 release. - Fixed a bug that would cause Guarddog to crash if you pressed ctrl+u while editing an address. - Removed use of ++ in the firewall script. - Added the netbios port 138 stuff to the DB and rolled all the netbios entries into just one entry: Windows Networking. - Renamed "Authentication" in the DB to the more accurate "ident/auth". - Added LDAP, LDAP-SLL, SWAT, Diablo II, IPP and Nessus to the DB. - Should handle broadcast packets better. (Your logs should not fill up with netbios/smb broadcasts). - Firewall script doesn't make as many assumptions about which directories the unix tools live in. * August 29th 2001 Simon Edwards <simon@simonzone.com> - 1.9.5 release. - Small clean ups. - The "Advanced Protocol Help" now works. - Fixed a nasty bug in the definition for ICQ that leaving the firewall wide open. - Fixed the annoying "[: -eq: unary operator expected" buglet that some people were seeing. - Fixed to work when virtual interfaces are defined. - Now handles NIC broadcast addresses properly. - Added code to enforce the Strong ES model (RFC 1122 section 3.3.4.2). - Now correctly avoids trying to use DNS when there are no decent NICs available. (This was causing slow reboots with iptables complaining when it could not resolve host names). - Added the ability to Import/Export the firewall script to the Advanced tab. It also has a "Description" text box for the benefit of people who want to juggle firewalls for several machines. - Since adding Import/Export of firewall scripts, it has become meaningful to run Guarddog as a non-root user to create scripts to be used elsewhere. It is now possible to run Guarddog as a mere mortal with reduced functionality. - Reformatted the changelog. * August 12th 2001 Simon Edwards <simon@simonzone.com> - 1.9.4 release. - No long uses the konsole to run the firewall script in. Guarddog now has it's own window that it can run the firewall and other scripts in. - When run, the firewall script was says what it is doing. Much friendlier. - Gnutella and NetMeeting support added. - Fixed a small bug that sometimes caused the same modprobe command to output multiple times. - Fixed a bug that was causing configuration to get scrambled when read in. * July 9th 2001 Simon Edwards <simon@simonzone.com> - 1.9.3 release. - Fixed a crash if you click to the right of the checkboxes on the protocol page. - Fixed a bug that would cause Guarddog to fail to read the existing firewall if it doesn't contain at least one user defined zone. - Add 'Connections' list which allows the user to select which zones the current zone should be connected to. - Rearranged the GUI somewhat. It's now much better layed out and sports icons and symbolic hints in places. - Added builtin help box on the protocol panel. Shows information and help about a given protocol. - Also replaced a lot of input boxes in the GUI with spinboxes. * June 14th 2001 Simon Edwards <simon@simonzone.com> - 1.9.2 release. - Netfilter/iptables is now supported. The generated firewalls use either ipchains or iptables automatically at run time. It also uses iptables state tracking modules to handle annoying things like FTP. This provides a *much* tighter firewall than old ipchains. - Advanced logging also part of the new iptables support, including rate limited logging and even log messages to warn when rate limiting is in effect. Reflected in the GUI is a whole new tab pane dedicated to logging. - The address lists now happily accept domain names instead of just IP addresses. - Also fixed a nasty bug in the ipchains firewall that was causing the wrong zone policies to be applied to packets. We don't call these a development versions for nothing folks! * May 9th 2001 Simon Edwards <simon@simonzone.com> - 1.9.1 release. - Protocols can now be set to either Deny/Accept and now also Reject. - It is now possible to specify user defined protocols. i.e. open/close specific ports. - 'printer', 'syslog' and 'ntp' have now been added to the network protocol database. * April 14th 2001 Simon Edwards <simon@simonzone.com> - 1.9.0 release. - The first developer release aiming at version 2.0. The 1.9.0 and higher code is a rewrite and redesign. Significant changes are the use of XML to store a database of information about network protocols. The work and code is also shared with Watchdog. I intend to fully document the XML format I've designed in the hope that others will find it useful and support it. - Guarddog now has the concept of 'zones' which allow you to place different hosts and networks into groups which can then have different firewall policies. - Router configurations are a target for 2.0, but this development version still doesn't support them, yet. * January 17th 2001 Simon Edwards <simon@simonzone.com> - 1.0.0 release, finally. - No real changes except for updates and additions to the documentation. * December 22th 2000 Simon Edwards <simon@simonzone.com> - 0.9.5 release. - Generated firewalls now setup the kernel networking protection. - Generated firewalls are now tighter, only opening the Local Port range instead of all non-privileged ports where appropriate. - Added option to always Reject Auth requests. (This can speed up POP connections). * November 30th 2000 Simon Edwards <simon@simonzone.com> - 0.9.4 release. - Small fix for ISDN users. (Thanks to Joerg Buchland). * November 22th 2000 Simon Edwards <simon@simonzone.com> - 0.9.3 release. - Now requires KDE 2. Most of the GUI code has been rewritten for KDE 2. - GUI has also been cleaned up somewhat. - It also attempts to automatically identify which interface is being used to access the net. (Thanks to J. F. Gratton). - Added an option to completely disable the firewall. * September 2nd 2000 Simon Edwards <simon@simonzone.com> - 0.9.2 release. - RealPlayer support added. - Small changes to the GUI to fix a few layout problems. Still not perfect, but much better. - Manual is much more complete now. Now has a tutorial and FAQ section. * June 11th 2000 Simon Edwards <simon@simonzone.com> - 0.9.1 release. - Packaged with RPM for Mandrake 7.1 (should also work with Redhat). - Some display glitch fixes, still more remain, grrr. - Should now be able to find the protocol database file ok. Sorry to those people who tried to get it to run from source and failed. - Uses sane defaults for checkboxes in new firewalls. * June 2nd 2000 Simon Edwards <simon@simonzone.com> - 0.9 Initial developer release.
