Filed under: Web-Hosting,www — Unichost @ 5:33 am

FLUSH DNS in different platforms

In Microsoft Windows, you can use the command flushdns to flush the DNS resolver cache.
Open the command prompt and type the following:
C:>ipconfig /flushdns
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.

In Mac OSX Leopard, you can use the command dscacheutil -flushcache to flush the DNS resolver cache:
bash-2.05a$ dscacheutil -flushcache

In Mac OSX versions 10.5.1 and before, the command lookupd -flushcache performed the same task:
bash-2.05a$ lookupd -flushcache

In Linux, the nscd daemon manages the DNS cache. To flush the DNS cache, restart the nscd daemon.
To restart the nscd daemon, use the command
#/etc/init.d/nscd restart

When I login to SSH and push the up arrow, the previous commands are shown. How do I clear or delete that log?

Clear the history for current login or current user.
#history -c

First find the history file for particular user.
Delete .bash_history file, will be recreated again next time.
#locate .bash_history
#rm .bash_history

It is not a best practice to totally disable the ssh command history on any dedicated server or vps server. It’s a quick reference to user’s past actions on server.

How to check php settings by using phpinfo on server?

Each server is setup differently whether it is a dedicated server or a virtual server, phpinfo() is commonly used to check configuration settings and for available predefined variables on a given web server.

phpinfo() is a valuable debugging tool as it contains all the data, information related to environment, GET, POST, Cookie, Server etc.

To create the file simply add the following lines of code to a blank document.

Save the file as phpinfo.php and place it in the desired directory. Lastly, call the script from a browser.

This php file will output detail information about the current state of PHP: PHP compilation options and extensions, the PHP version, server information and environment, the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License as well.

If the cPanel service is down, you can’t perform any of the task trhough WHM to resolve the issue. In fact this service should get start automatically as per the documentation says, but there are chances it will not come up if there is a problem with the configuration. So, what’s the resolve? Get into the server via ssh. What if you don’t have that? Sorry, that’s the only option left with you, so you will need to get connected with the system admin/ vps or dedicated hosting provider / data center technicians to get the cPanel cpsrvd service restarted for you, or start the cpsrvd service if it is stopped.

If you have access to ssh, it’s good. You can perfrom one of the folloing command on your server. Login to server with root access. Then, run one of the following commands:

If you are sure that cPanel service is stopped… ?
To check the status…
#service cpanel status
cpsrvd (pid  7575) is running/stopped…
If stopped… to restart the cpanel service…
#service cpanel restart
#/etc/init.d/cpanel restart
#/etc/rc.d/init.d/cpanel restart

The command will stop the services first and then start the cpsrvd daemon again.
You should be able to login to cpanel/whm from your browser now.

How do I know if I have a secure connection for online transactions?

Filed under: Online Security,Web-Hosting — Unichost @ 7:08 pm

Online transactions – Major security concern.

Address of the secured website/online store always starts with http(s). So ssl_certificatebefore you enter any transaction details on the trasanction page, check if the page is secured with the certificate verified. In the web browser: Internet Explorer or FireFox or Opera or Safari etc., you will see a lock icon (lockpad) in the Security Status bar. In IE the Security Status bar is located on the right side of the address bar.

The certificate that is used to encrypt the connection also contains information about the identity of the website owner or organization. To get the more information about the installed SSL certificate, you can click the lock to view the identity of the website.

If everything is okey you are in safe hands.

Happy shopping!

Why dont you provide unlimited bandwidth and unlimited web-space plans

Filed under: Bandwidth,Web-Hosting — Tags: , — Unichost @ 6:44 pm

Do you provide an unlimited data transfer and unlimited web-space hosting package?

No, we do not provide unlimited hosting packages as there is no such ‘unlimited’ thing exists. In order to ensure high quality bandwidth and uptime to our respected customers we don’t allow anyone to be hosted on our web server to use unlimited bandwidth, data-transfer / throughput.

There are some hosting provider exists that offer free hosting or offer “unlimited bandwidth” and “unlimited web-space” plans. But after reading their acceptable use policies you will find that no site is allowed to use an “excessive” amount of resources. If you use too much resources, whether it is disk-space, bandwidth or CPU time, these “unlimited” hosts will ask you to upgrade or leave or will suspend your website.

We don’t give false promises.
