Linux servers are extremely powerful multitasking, multi user machines which utilize ssh browser for control and management. If you've got a Linux server, you will most likely get a grip on it together with Secure Shell or SSH.

SSH uses port 22 and protection services, along with terminal products and services. A few weeks ago, Telnet has been the protocol used to communicate with and control remote servers. As with the case of FTP, a better variant of the protocol has been needed for modern hosting scenarios. You will need to put in an SSH client to enable communication with your web host. You're going to want the IP address of the SSH server and your consent credentials. This will be available from the web host. It is possible to find a variant of this application together with your favourite search engine.

Once downloaded enter the port and authentication information in the options section of PuTTY, and make sure you save this settings.

Using PuTTY, login to a server. When connected you will notice that a small re-sizable window introducing your Linux server login prompt. Give you the appropriate credentials and you will then find the principal system prompt for the Linux server.

Since Linux is multiuser, other users could be logged into the machine. This really is but one of the advantages of using Linux in a system environment. Numerous users may authenticate and make use of the resources of the machine. Users may have different functions, such as administrator, user, etc.. Your ssh browser will soon be restricted to the rights granted to your particular user accounts.

It is most likely not just a good idea to login as the root user. The root user, or super user accounts can make changes which you may not want. It's ideal to work with a regular user account for regular pursuits. Depending on the distribution you're using, you can implement a command like:

This command allows one to perform administrative tasks, and never admin level statements. You may be supplied an instant for your private password. When your account name is on the "sudo su" list (see your administrator about any of it), then you'll be given administrator privileges, and soon you logout of the admin accounts. Upon logging out, you will soon be back in your regular user accounts.

Once you've gained access to your own server, you'll be able to issue shell commands to navigate and manage the host. The commands used depend on the "flavor" of casing being used by your machine. Most Linux users will probably be using the "bash" shell but could use the "dash" casing instead.

In short, logging into a remote host's shell, you will have to utilize the ssh protocol. You can utilize the free PuTTY application with this. In the future articles we'll examine useful shell commands that every administrator needs to possess in their tool box.
