CCNA / CCNP Lab Setup

My CCNA/CCNP Lab

I’m building a lab at the house to use to study for CCNA and CCNP certification. On the left are some old Cisco routers and switches scrounged from work. On the right are some routers and switches I bought on eBay. I have a Cisco 3620 with an Async cable connected to all of the console ports so I can access all of the systems console ports thought the 3620.

It’s just about ready to go — I’m just waiting for an order of DCE/DTE crossover cables to arrive and then I’m in business. I hope to be able to get things set up so that I can administratively reconfigure the systems without having to make a lot of patch cable changes to create different scenarios… we’ll see.

Finally, in the bottom left corner, is an Ubuntu Linux system I’m using for general management of the switches. It’s got tftpd set up, and can receive syslog messages from the systems if I need to do some heavyweight log troubleshooting. Eventually, I hope to get it set up as a TACACS server as well.

Update #1 — mounted the equipment into a rack that was donated to this cause.

SSH Tunnel Howto

This was previously available on my homepage at Cornell, I’m trying to centralize all my websites to a single location and I include it here for your enjoyment.

Where I work, the Cornell University School of Electrical and Computer Engineering, the network only allows secure encrypted connections into the servers on the network. If you want to transfer files to and from the network, you need to use a program that supports SFTP or SCP2 transfer protocols. For users of Microsoft OS’ I recommend using SSH from SSH, Inc. which can be downloaded from ftp://ftp.ssh.com/pub/ssh/.

Unfortunately, many web design programs and other applications that use FTP do not support SFTP or SCP2, Macromedia Dreamweaver 2004 is the first and only to date that I’ve heard of that does have SFTP support built-in. Don’t worry… there is a way to get around this limitation by following a few simple steps.
