A few years ago a fully-dedicated 100Mbps up-link for a dedicated server was a dream for many folks. Not anymore! The bandwidth pricing went down drastically, the internet connectivity speed has increased a lot. Nowadays even a budget dedicated server has 100 Mbps up-link and the question is how much bandwidth you can push? Let’s [...]
Remember the time when 50GB monthly traffic for a dedicated server was so much bandwidth. Nowadays, 1000GB, 3000GB or even higher traffic monthly limits are common, but there are quite a few dedicated server companies lately offering 10TB (10000GB) monthly traffic limit. This is quite a huge monthly limit and 99%+ web sites will never [...]
If you are running squid or any other proxy software and you want to hide your real IP for security or privacy you should adjust your proxy server source or config to disable the following HTTP Headers: REMOTE_ADDR = proxy_server_ip HTTP_VIA = proxy_server_ip HTTP_X_FORWARDED_FOR = proxy_server_ip With squid (version 3) you can setup the following [...]
Are you looking forward to balance HTTP or HTTPS traffic to multiple back-end servers? Nginx is one of the best choices – it’s very lightweight, requires less resources and it’s completely free. You need to compile the nginx (there are many resources and howto’s) and add the following lines to your nginx.conf file: upstream webcluster [...]
Nginx developers have released two patches – one that fixes null pointer reference, gx_http_parse_complex_uri() buffer underflow. Update immediate or your site can be attacked and nginx stopped remotely (so I heard). Download the latest stable version and recompile the binary. Then run kill -USR2 nginx_master_pid Make sure you see new master nginx process running (you [...]
The amount of web traffic that plays a role in dynamic Internet content is large, and it has become much larger as users demand higher levels of personalization. It has become more important for content providers to provide information that is tailored to the specific needs of the customer. The biggest challenge with achieving this [...]
It’s always better to use SSH not Telnet if you are connected from a remote location and someone may snoop your password. You must enable SSH on the Cisco gear by using: crypto key generate rsa Tune timeout and re-tries: ip ssh timeout 120 ip ssh authentication-retries 3 Look up if you have SSH enabled [...]
Many popular websites and blogs have some serious problems with uptime and reliable hosting. Some hosting services are just, plainly put, bad yet others simply suffer from issues with bandwidth and reliability. Using a Content Delivery Network can definitely help with uptime, as well as decrease the load on your shared hosting account or dedicated [...]
I suggest setting up maximum memory that named can use – e.g. for zones and caching. in named.conf use the following value in options {}; settings: max-cache-size 50M; This means that named shouldn’t use more than 50MB of system memory when available. A pretty good hack to make sure named doesn’t take all the server [...]
This is a very good question. I have been running Windows based workstation for over 10 years and it’s been a pleasant experience, unless I get the blue screen from time to time. Anyway, I am always using ZoneAlarm lite firewall software – it’s completely free and is good enough for most home users. Of [...]

A virtual private server is one server that has been partitioned near the root, and is split into numerous servers which are dedicated. The good thing about this is that the user can share the cost of the connection, as well as the maintenance and hardware. Like the shared hosting, you can split the cost [...]
A control panel is tied with an operating system to maintain and check the controls and settings of it. The major functions performed by control panel are controling of web hosting accounts, account features, disk space, traffic, POP3/IMAP settings, disk partitions, software, network connections, date, time and other options. It also is used for managing [...]
By default Centos, RedHat and Fedora starts multiple daemons that are actually not needed, for example: nfs nfslock cups gpm and I am suggesting you disable these services asap. You can turn it off via chkconfig command or even remove from the execution at init levels as well. chkconfig –del cups chkconfig –level 3 cups [...]
My personal choice is Cpanel – it’s somehow more friendly for me and has a lot of more features. However, DirectAdmin requires less resources from my own experience. Anyway, I will stick with Cpanel – I have used it for years and it does a nice job with hosting small web sites. For large site, [...]
