Does sevenforums have any network specialists. like internetworking?

[Skylais]

Just wondering, i wanted to ask some simple questions. Such as what emulator program one might using when configuring switches and routers through telnet or ssh.

I'm not a network specialist, but you are asking simple questions. From windows I use PuTTY for SSH like most people. From linux SSH is built into the terminal. Hyperterm can also be used to configure switches and routers.

If you wish to have a tabbed interface than SuperPuTTY can be added on top of the normal putty application, this can be helpful when managing multiple telnet sessions

https://code.google.com/p/superputty/downloads/detail?name=SuperPutty-1.3.0.11.zip&can=2&q=

If you use GNS3 then by default you should already be running SuperPuTTY or PuTTY



If not and studying for any cisco certifications then I would strongly recommend trying out GNS3 for router emulation since in more complex topologies for CCNP and CCIE you may not have the equipment necessary.

   Tip

You can bridge GNS3 with real equipment by creating a cloud and tying it with a bridged loopback interface

65. What is the purpose of a DNS server?

The DNS server is used to maintain the mapping between the IP addresses and names of various devices.


That is the answer by cisco for that question, its confusing. I thought DNS translated ip to domains like googles ip being translated to Google. ?

Nope, it's the other way around You put www.google.com into your browser and the computer will use DNS to find it's IP address so you can be routed to the appropriate server that holds Google.



On a DNS server there is simply a hostname with an IP address next to it. Think of it like a phone book, when you wish to phone someone say 'Bob' your phone doesn't dial bob but rather look at it's phonebook for bobs number to dial. DNS is the same process with domain names (name) and IP addresses (number).

This is what it looks like on the DNS server side:



When a device goes to this server asking 'What is the ip address of 'Home-Laptop'?' the server will respond back - 192.168.1.50

Hopefully this helps,
Josh

Thanks, made the only a in class. 95.
Class average was 63. Will admit, balancing a cisco course on top of a bunch of high level high school classes, including some that count as college credit is very taxing. I like internetworking so far, especially using the CLI and learning commands and stuff.

Aye cisco is good crack but you've really got to find that speciality otherwise you'll be spending your entire life learning syntaxes!
