Free sparco pool filter warranty software for linux

Compact Filter is a network packet filter for Linux. It features an easy-to-use compact filter representation and high performance.
The main features are: easy to use interface, compact filter representation (memory efficient), and very high performance.
A difference between CF and other firewalls, such as Netfilter, is its representation of the ruleset. In CF the user writes a filter which is then compiled and optimized in user-space. The optimized filter is then loaded into the kernel (using netlink). Consequently the in kernel packet filtering code only needs funtionality for setting up a filter and filtering packets, while the more complex code of optimizing the filter remains in user-space.
Because of the continuous increase of the bandwidth and the security threats, firewalls have to evolve towards more efficient filtering schemes. The truth is that the existing scheme does not scale so well with the combined growth of bandwidth and rulesets.
Our aim is to try another approach to perform packet filtering where we minimize the complexity of the filtering process. This result in, both, a reduction of the required CPU power to filter packets and a simpler (and smaller) kernel code. Of course, we are pushing all the smart and complex part out to the user-space, but, developing in user-space is much simpler and safer.
Enhancements:
- changed -d option to delete all filters
- added -D option to delete a specific filter
- changed default policy to permit rather than deny
- added -l option on flex to support --yylineno on older versions of flex
- new and improved install guide

Shrew Proxy/Filter is a tiny proxy built on WEBricks HTTPProxyServer, extended for both URL and content filtering. Shrew Proxy/Filter is designed to be small, simple to configure, and easy to install.

It is extremely small, lightweight, and works quite well. All blacklists (both URL and content) are plain text, so most published lists can be simply dropped in and used.

Kmail POP filter with antispam/scoring contains improvements for KMAIL POP filters.

Read the content of file README for the use information and for applying the patch.

Filter rules with action with one score value (only for kde-3.5.x)

- The porting for the other versions will come make only from request.
- This is useful to set up one action on a message from match the more filter rules (as an example, a rule on XP, rolex and another on best, price, and ....)
- The action is set up when the sum of score value is at least 100%.

For kde 3.x

- Highlight of the e-mail marked for the download or the delete.
- Tool-tips on the text that exceeds the dimension of the columns.

- Ordering also for type action.
- Set action to delete of the messages that have one type of action or they are old at least X of days.

- A single key press (key D, E, L, Up, Down) for every message (stop of, watches, selection, watches, sets up, for every message).

- Use of one single list view for all the various types of match message-filters.
- Adding for every message the visualization of the name of filter that is matched with the message.
- Possibility of, easy and quickly, to see only the messages that they correspond to one action.

- Filter from to the header of the body of the message (therefore it is possible to filter for the name of the file attached).
- Filter from initial rows of the body of the message.
- The user can specify the minimal and maximum number of rows of the body of the message to download (the number of rows comes calculated in proportion to the dimension of the message) .

smf-clamd is a Sendmail milter for the ClamAV (Clam AntiVirus).
Sendmail filter for ClamAV aims to be lightweight, reliable and simple. Sendmail filter for ClamAV is written in C.
Main features:
- It has a hosts/networks whitelist;
- It can scan messages less than a defined size only;
- It rejects infected messages at the SMTP DATA stage;
- It can add an information header with scan results to scanned messages;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required;
- No temporary files are created.
Enhancements:
- A workaround for the Sendmail socket unsafe error on some platforms was implemented.
- Clean email messages logging was removed.
- Configuration file, default user, and working directory were changed.
- The format of log records was changed.
- Some samples of start-up scripts were added.
- The new TODO tasks were added.
- Cosmetic enhancements were made.

DNS Blacklist Packet Filter project is a Linux netfilter client that decides whether to accept or drop packets based on the results of a DNS blacklist query (such as MAPS, SORBS, or SPEWS, to name a few).

One use is to filter all incoming SMTP SYN packets for spam filtering.

smf-spamd is a Sendmail filter for SpamAssassin. Sendmail filter for SpamAssassin aims to be lightweight, reliable, and simple rather than have a myriad of options.
It only scans the messages less than defined size, has a hosts/networks whitelist, performs subject tagging if SPAM is detected, adds an information header, copies SPAM messages to the defined "garbage" mailbox, rejects SPAM messages at the SMTP DATA stage, and logs all filter activities to syslog.
The code is small (does not exceed 580 lines), fast, stable, and few resources are required. No temporary files are created.
Main features:
- It has a hosts/networks whitelist;
- It can scan messages less than a defined size only;
- It can tag the Subject if SPAM has been detected;
- It can add an information header with scan results to scanned messages;
- It can copy SPAM messages to the special "garbage" mailbox;
- It rejects SPAM messages at the SMTP DATA stage, if SPAM score is greater than a defined value;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required;
- No temporary files are created.
Enhancements:
- Incorrect handling of missed Message-Id: header was fixed.
- Cosmetic enhancements were made.

The fairly fast packet filter (FFPF) is an approach to network packet processing that adds many new features to existing filtering solutions like BPF.
fairly fast packet filter is designed for high speed by pushing computationally intensive tasks to the kernel or even network processors and by minimising packet copying.
By providing both access to richer programming languages and explicit extensibility, it is also considerably more flexible than existing approaches.
FFPF provides a complete solution for network monitoring that caters to all applications available today. Exploiting its extensibility, the language can even be used as a meta-filter to `script together filters from other approaches, such as BPF.
Main features:
- fast: processes significantly more packets per second than LSF (reference)
- scalable: transparently supports hardware assist, like that given by the Intel IXP2x00 network processors
- backward compatible: supports all existing libpcap based applications
- extensible: separates functionality from the framework. FFPF currently ships with implementations of BPF, Aho Corasick, Boyer Moore Horspool, and many more
- modular: new functions can be written in as little as 3 lines of code
- secure: relies on Keynote for authentication and resource control
- open and standard adherent: licensed under the GNU General Public License (GPL). It implements the Monitoring API (MAPI) draft as designed by the EU-SCAMPI consortium
Enhancements:
- enabled kernelspace processing
- enabled all 5 buffer implementations (Continuous, Fixed-size slot, Variable sized slot, Double ring and Index)
- added TCP stream reassembly and early implementation of zero-copy reassembly
- added PCAP input and output support, for userspace testing and offline use
- added additional minor functions: TCP Synprotect, output to files, ...
- added support for UDEV
- extended controlplane: flowspaces can now be queried for live state
- fixed up many bugs, hacks and irregularities.
