CSF Firewall, version updated!(csf v5.11)

CSF firewall commonly known as Configserver Security and Firewall has become one of the popular firewall not just because of its easy of use it also provides a cpanel interface and can be easily installed and tuned by any users.

Yesterday, we upgraded CSF to latest version which is 5.11 to offer more protection to our client.

Here are some major changes in the new version:

Added a new 7th argument to BLOCK_REPORT that includes the log lines that triggered the block (excludes LF_NETBLOCK and LF_PERMBLOCK)

Added new CLI option csf –tempallow (csf -ta) which works in exactly the same way as csf –tempdeny (csf -td) except it provides a method of temporary IP allows for a given duration. csf -t, csf -tf and csf -tr now apply to both deny and allow entries

Allow the use of a duration suffix in csf -ta and csf -td for m, h and d (minutes, hours and days). Only one suffix allowed and only integers

Updated UI entry for adding and removing temporary allows and blocks

Display temporary block TTL in days hours minutes and seconds

Added new CLI option csf –watch [ip] (csf -w [ip]) and configuration option WATCH_MODE. This new option logs SYN packets from a specified source as they traverse the iptables chains. This can be extremely useful in tracking where that IP is being DROPed or ACCEPTed by iptables. See readme.txt for more information

Modified csf and lfd init scripts to be LSB-compliant

Modified BOGON/DSHIELD/SPAMHAUS block list retrieval to only download the list if it has not already been retrieved within the configured interval. This is to help prevent blacklisting by the list provider for repeated downloads after frequent lfd restarts

Fixed problem with csf -q and csf -sf not restarting the firewall if there was a previous startup error.

How to choose a Good Domain Name

The domains are registered regularly at a record level, new domain expansion and innovative thinking still offer thousands of brilliant choices. However while looking for a desired name it is important to consider the purpose of a domain name first and it should be shorter and memorable that enable your visitor’s to reach your website easily.

Consider following points before registering a domain name;

Short & memorable: – People don’t remember longer domain name easily, the shorter your domain, name, it would be easy to remember and also it minimize the chances of typographical mistake while your users typing it to reach your website. Also consider a domain name which has marketability so that you can brand them easily.

Momentous – A short domain is not worth without connotation, like if you go for 4xf0l.com it would be not easy to type or remember. Select a domain that narrates and reflects your website in their domain name so that people can understand and remember them easily such as flickr.com, twitter.com in this case.

Apparent & Concise –Clear & precision are vital factors when choosing a domain name, it should sounds well and should be effectively communicated over the phone.

Exposure: In order to take full advantage of your sites exposure, consider to include matching keywords in your domain unless you’re going to consider a very short, clear and meaningful domain name. Even two words that which can best describe your web site are good to go with, however avoid using dashes, underscores and numbers into them. It would be best if you perceive both the human and search engine while deciding a domain name to buy.

Best Domain Extension: Select best domain extension like .com is still the best choice and similarly .net could be the best second desired choice although you may also consider country specific tld like .com.bd, co.uk, .us, .asia or .us In case if you have planned to target a country or region like for example if you’re developing a site to target BD country specific you should go for .com.bd
