Hi Guys,
I wanted to know what console login mean!
Are there any other kinds of login too?
And what is the need/use of console server?
Please help?

Console login is when you have a monitor connected or a serial device connected and you want to login to the local console

There are two ways (usually) that you can log onto the console, if you have a monitor and keyboard attached to the system then that would be your console. If you do not have a monitor and keyboard then the system uses serial port A for console connectivity, you would have to connect a terminal or a pc running terminal emulation to the serial port.

In a datacenter environment where there are a lot of systems, the serial ports of all the systems are connected to a terminal server. The terminal server would have an ip and each serial port would be assigned a port number, and you would telnet into the port -

telnet xxx.xxx.xxx.xxx yyyy where xxx is the ip address of the terminal server and yyyy is the port number of the serial port you are trying to console into.

What i understand is that console login is the only way i can access the server when it is in siingle user mode ( or when it is rebooting or when it is shutdown ). SSH, telnet and others will get disconnected.

Please tell me if i am right!

Yes, that is true unless you startup the network services and then run those services. Other then that console is just used to say where root can login from.
