All you need to certify yourself

Hostname is the name of the router. It’s up to us what we name it. It’s like giving a name to our own systems. If we are using a command line interface to access the router or switch, then we can see the current name of the device before the prompt.

I had been looking for shortcuts in the Linux environment. Unfortunately I couldn’t find a single place where I could get all the shortcuts like Windows. In Windows, I can go to help and support and find out the keyboard shortcuts.
I got some of the keyboard shortcuts of Linux from another blog:
Ctrl+B – Move the cursor back one character.
Ctrl+A – move to the START of the line
Ctrl+E – move to the END of the line.
Ctrl+U – delete from the cursor to the beginning of the line.
Ctrl+K – delete from the cursor to the end of the line.
Ctrl+W – delete from the cursor to the start of the word.

SSH is the preferred protocol for remote communication with Cisco products. SSH is more secure than Telnet because all the data is sent with encryption.
To see if SSH in Cisco router or switch is enabled or not issue the following command:
Certhacker#show ip ssh
%SSH has not been enabled
You can see that SSH has not been enabled on the router or switch. To enable SSH do the following:

Static routes are those which are manually added by a network administrator. Their purpose is to hardcode a route for a specific network or host. The opposite of a static route is dynamic route which is automatically created by the router.
The syntax to add a static route in Cisco IOS (router) is as follows:
certhacker(config)# ip route <IP> <netmask> <Next Hop router interface>

New version of CCNA dumps has been released by Pass4Sure. The previous version was 8.14 but in July the new version released is 7.58. This versioning is really strange to me. It would be great if anyone guides me through these version numbers. EaglePk has given the link to the latest Pass4Sure downloads. Please correct me if there’s another version later than this one. Thanks.
Download Links for V7.58 are as follows:

It has been quite some years when I started my career in the IT service industry. I have been in IT support and was quite confident that I have got all the skills to manage an IT department. But a few days back, I attended a training on ITIL which stands for Information Technology Infrastructure Library which got me into thinking that being aware of technical things is not all what is needed. Managing the IT department is more than having technical skills.

Cisco: The Complete Reference is a lofty title for a book, and one that you could take
in a multitude of different directions. Some think that a book with this title should be
the “end all and be all” of Cisco books, including every possible Cisco technology and
the most obscure details of those technologies. Unfortunately, that book would
consist of over 50,000 pages, and it would be obsolete by the time you got it. (Cisco
has been trying for years to write that book; it’s called the Cisco web site, and it’s still
not complete.)
