Useful Information

If you use web hosting where the provider has specified the amount of space available,  junk emails can cause the space to fill up quickly.  Some hosting providers like Hostgator also specify the maximum number of inodes you can have in a shared hosting account, and each email corresponds to separate inode.

In Cpanel , you can  disable catch all by setting default ID to :fail: no such user here

For reseller / VPS/ dedicated server, you can also login to the WHM >> Tweak Settings and set “Default catch-all/default address behavior for new accounts. fail is usually the best choice if you are getting mail attacks.

Shell/SSH access on a Linux, BSD or Unix-type server is access to a command prompt on the server itself. This enables you to issue commands as a user of the system – for example, for changing permissions on files, copying, moving, deleting and moving to a folder.  Most of the cheaper web hosting packages do not offer shell access.

On a dedicated server or VPS, you will probably also have “root” access (like Administrator access in Windows) and you will be able to compile and install programs, update and patch your system and a whole lot more.  Though most web hosting Control Panels like Cpanel offer many features, they have many limitations, like you cannot find the files last modified or delete certain files easily.

Some of the popular  SSH clients are:

• Putty – http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html  - popular SSH client, most widely used, small file size, available as an .exe file
• Openssh – http://www.openssh.com/

In the last two years I have been surprised how perfect strangers seem to know my birthday and people I have never heard of, who have got hold of my email addresses which I have never published online. Unlike most democratic countries, in India there is some ambiguity on the privacy rights of private citizens. And if the information obtained by snooping is misused, who will compensate me for the damage / harassment caused?
