A shell account is a user account on a remote server , traditionally running under the Unix operating system , which gives access to a shell via a command-line interfaceprotocol such as telnet or SSH . 
Shell accounts have been made available to the public by Internet Service Providers (such as Netcom (USA) , Panix , The World and Digex ), although in rare instances. They were used for storage , web space , email accounts , newsgroup access and software development .   
Shell providers are often found to offer shell accounts at low-cost or free. These shell accounts Generally Provide users with access to various software and services Including compilers , IRC clients , background processes , FTP , text editors (Such As nano ) and email client (Such as pine ).   shell Some providers May aussi allow tunneling of traffic to bypass corporate firewalls .

If you are comfortable with the command-line interface That Linux provides, you will probably be comfortable with a Linux account on a Linux or Unixcomputer managed by an ISP. Once your modem connects to the other modem and you log in, it is the same as an xterm session or a console login (without graphics capabilities) on your Linux box, except that the remote computer is connected to the Internet. You usually use a standard Unix shell, with roughly the same choices available on your own Linux system, BBS provides.

Most recent vulnerabilities are not remotely exploitable Directly On Most systems. This means that most systems are not at risk for remote attacks from the Internet. Many of the vulnerabilities can be taken advantage of by someone with a regular shell account on the system.
