reverse telnet [7:26631]
Exactly what is reverse telnet and how does this relate to TCP portnumbers? >From what I know, normally a server, e.g. a router, is running a Telnet deamon. This deamon is waiting for incoming connections on its serverport 23. So I guess, after the init, a client sends a packet Dest Port = 23, then the server responds with Source Port 23, Dest Port = something above the 1023 range and we have Telnet. I red that with reserve telnet, port 2000 + tty number is used. So how must I figure this: does the client send to packet to the Telnet deamon on the router on Dest port 2003? or how does this work and why is it called reverse?

Tnx for the feedback. Did you do CCNP / CCDP as well? If so how do these exams compare to the Written CCIE?

function of loopback interface [7:27181]
>From what I've read the functions/benefits of the loopback interface includes that "it provides an entry point for console based telnet sessions in the event that all physical interfaces are down". Why is this a benefit? You can always connect through the console to configure the router even if you do not have a loopback interface defined, can't you? So exactly, what are the profits that this can be done "telnet-based"? A practical example would be great.

Re: Passed CCNA&CCNP in a month [7:27142]
I find most people here are confusing certification with being knowledgeable. If you are knowledgeable enough to do your job well, why go for the certification anyway? Status? On the other hand, employers ask for certifications more and more, and mostly won't give you a job with a content or salary which is compatible with the knowledge-level required for certifications, at least when acquiring it the hard way. The reason some certifications are easily obtained like MCSE, CNE and the likes are that M$ and Novell are using the revenues for the certifications as an extra source of income, without bordering to make good exams with a database of 1 or more questions, which not only depends on learning some facts. Here lies the answer, just let M$, Cisco and so make the examquestion database so extensive that learning the answers to all the question in fact would be the same as learning all the relevant material without having access to the exam qeustions. Personally, I'm using a combined approach. I want to understand fully what I learn and will learn more than strictly is necessary for the exam, but I will use any good prep-exam/braindump in the days for my exam just to ensure my efforts will yield the desired result.
