ASA SSL Clientless VPN Plugins

These plug-ins are buried so deep in the Cisco site, it took me a good hour to track them down. These allow you to add functionality to the clientless SSLVPN on an ASA through Java. These ROCK for setting up remote administration (without a full VPN) for a network.
SSH Plugin
RDP2 Plugin (supports Win2008/W7)
VNC Plugin
*Note - for the RDP2 plugin, the ASA does not have a built-in plugin type for it. You must manually type "RDP2" as the plugin type when uploading it to the ASA* - click thumbnail below for screencap.

Which Certification Should I Pick?

You may be asking yourself which certification track you should focus on. If you are already in a set career path, like network engineering or system administration, then your best bet is to select something from your given area of expertise. Cisco's track for networking or microsoft's track for systems administration are rock solid.

If you are interested in taking any direction with your career or are looking for some change, take a look at certification magazines annual certification salary survey to get some ideas. The highest paid certifications are typically some of the hardest to earn, but if you really want to change your careers direction, you are bound to ride the wave with a high paying cert.

Brocade Certified Network Engineers (BCNEs) Highest Paid

Storage has seen a huge amount of growth and interest in the more recent years. The average cost of a megabyte seems to have been halved year over year since the 80s.

Tidbits

Tekcert Tibits provide a quick snapshot on how to configure different technologies that align with exam topics.

 

EIGRP - Basic EIGRP configuration with three routers and different connectivity types between routers.

ISO to USB Stick

DVD

I recently was attempting to install CUCM 7 on an older MCS-7825 server...unfortunately, the server is old enough that it only had a CD-Rom drive (and CUCM 7 is on DVDs)...Stumbled onto this utility:

http://sourceforge.net/projects/unetbootin/

Allows you to "burn" an ISO image onto a USB stick (and make a bootable USB drive in the process). Nice! Worked well for my CUCM install, but has a million other uses too.

Cisco Revises CCNP Certification Track

Cisco recently revised their CCNP track to make it align with actual job requirements (such as troubleshooting problems on networks full of Cisco equipment).What do these changes mean for current Cisco Certified Network Professionals? Well, not much other than  you still get to take a 642 level exam to renew it. However, for all you non-CCNPers out there, tighten your belts and sharpen your pencils because you are in for a bit of a change.

Recover ASA Software from ROMMON

Houston we have a problem...

Just putting these commands in a handy place since this seems to happen more often than I thought...

rommon #1> ADDRESS=192.168.1.10
rommon #2> SERVER=192.168.1.1
rommon #3> GATEWAY=192.168.1.1
rommon #4> IMAGE=asa800-232-k8.bin
rommon #5> PORT=Ethernet0/0
rommon #6> tftp

Testing AAA on ASA/PIX

Stole this one from the Cisco Reader Tip - very handy! Allows you to test AAA user authentication from the ASA command-line:

ASA# test aaa-server [authentication|authorization] <aaa_server_group> [host
<name>|<host_ip>] username <user> password
<pass>

For example:

ASA# test aaa-server authentication TACGroup username johndoe password cisco123

if authentication is successful - INFO: Authentication Successful
if authentication fails - ERROR: Authentication Rejected: Unspecified
