telnet uses and explanations

I have been looking and reading about telnet, but still cannot grasp the uses for it. I know it has some uses in rooting and things of that topic. I was reading on wikipedia about it also, but on to the main question. Will telnet do whatever I may need it to do through a wireless connection on my laptop? I was trying to run through an article on HBH earlier and could not get any results that it was saying I could get. Maybe some tips or points would be appreciated. Bluntness is greatly accepted and not taken harshly.

Telnet is a tool, not an "exploit". It doesn't do anything special, really. Just another way to remotely access a computer with credentials.

It's been widely replaced by ssh, since telnet traffic can be sniffed.

Don't worry about it, it's not a critical part of modern security systems.

Thank you Lesser, so SSH is the new thing to use, huh? Well I guess I will read up about it and learn some of it. Thanks. I thought you were leaving? Anyway glad to have you stay awhile.

I'm hibernating.

SSH is has the same concept like telnet, (where two computers exchange data among each other) but SSH uses a secure channel, where it needs public-key cryptography for authentication.

telnet, however, does not encrypt the data transmitted. In a simpler way, It means that all the data are sent in plain text and anyone with a packet sniffer can grab the details (user name, password, etc.)

it can also be intercepted for man- in -the middle attacks due to lack of authentication using IP spoofing.

Most systems such as Linux and Macs support SSH (i can't remember if they still support telnet) Windows has a telnet client by default but is no longer included with Vista. Who needs it, everyone uses PuTTY anyway.

so ssh cannot be used as an exploit, but it can be used to monitor or spy on people sending emails to eachother? I have been reading about it and realized the use of it, but I was thinking of other uses for it, like monitoring emails or intruders on your emails. correct?

No. SSH is a TCP/IP protocol and is used to connect to other computers.

It's like this :

my computer and laptop has VNC. Let's say I have some files I need on my laptop, and I'm in college, which is around 10km away.

So I connect to the internet with my laptop, and I use my SSH client to connect to my computer by entering my home pc's IP address / dedicated domain name, open VNC viewer to view and grab what I needed.

And then my dad asked me to check the network in case my brother / sister is using the internet for too long and to see if anything is wrong with the network and check what sites and emails they are sending / using.

So, I'll simply install a packet sniffer on the home network's server and check the system logs.From the captured data, I can simply check their e-mail details, website logins, types of files downloaded, etc.

If you want to know more, there are lots of website tutorials and books explaining this protocol.

To anyone: If i'm wrong in any part, just tell me and sorry in advance.

thank you
