My attempt to install vcenter server to manage overall hypervisor was not a successful one.. i didnt read the hardware requirements in the first place and i’ve just figured it out after the error message popped up… soo.. i did some search on the hardware compatibility list and it says that only Xeon based server processor is supported.. unable to tinker further on the various features on Vs made me sad 😥

Terminal Access Controller Access-Control System (TACACS) is a remote authentication protocol that is used to communicate with an authentication server commonly used in UNIX networks. TACACS allows a remote access server to communicate with an authentication server in order to determine if the user has access to the network. TACACS is defined in RFC 1492, and uses (either TCP or UDP) port 49 by default. A later version of TACACS introduced by Cisco in 1990 was called Extended TACACS (XTACACS). The TACACS protocol was developed by and is proprietary of Cisco Systems.
TACACS allows a client to accept a username and password and send a query to a TACACS authentication server, sometimes called a TACACS daemon or simply TACACSD. This server was normally a program running on a host. The host would determine whether to accept or deny the request and send a response back. The TIP (routing node accepting dial-up line connections, which the user would normally want to log in into) would then allow access or not, based upon the response. In this way, the process of making the decision is “opened up” and the algorithms and data used to make the decision are under the complete control of whoever is running the TACACS daemon.
TACACS+ and RADIUS have generally replaced TACACS and XTACACS in more recently built or updated networks. TACACS+ is an entirely new protocol and not compatible with TACACS or XTACACS. TACACS+ uses the Transmission Control Protocol (TCP) and RADIUS uses the User Datagram Protocol (UDP). Some administrators recommend using TACACS+ because TCP is seen as a more reliable protocol. Whereas RADIUS combines authentication and authorization in a user profile, TACACS+ separates the two operations.

Learning and Learning

I’ve installed GNS3 and its CISCO emulator dynamips on my virtual machine and have also tried to download its IOS from undisclosed source. i’ve tried to access, understand more about networking and its various devices and often used command as well as to firm up my knowledge on the basic internetworking concept.. i’m plannin to join the CCNA exam perhaps sometime towards the end of this year.. hopefully the company will support to pay the exam fee as a part of employee training / development purpose…
Well.. life’s been much more exciting here in Bandung, Indonesia.. although i don’t have the privilege to hands on tinkering with their blade & vsphere, they at least gave me a glance through what is what.. and as i sat down, they’ll answer my questions in a very much pleasure tone.. and the more i know.. i realized that my learning path is still faaaaaaar far away and this perhaps was just the beginning…
and at least i need to start somewhere…
Last week i made my mom angry for staying at my friend’s house.. she was worried and and mad as i told her that i’ve spoken to her earlier last week.. but in fact she forbid me to stay at my friend’s house without any acceptable reason.. well.. i’m a grown up man don’t i? i very much requires reason on WHY she doesn’t want me to stay @ my friend’s house.. looks like she doesn’t have any reason why.. and i don’t quite like her attitude on being such a naggy mom.. i didn’t spoke to her since.. well.. sighs.. i understand that she’s totally care for my well being but hey.. tellin me to go shower early, sleep @ 10pm, etc isn’t the care i want..
so.. for girls / moms out there.. please read this.. life’s just like a supply & demand.. u gotta find balance somewhere.. and although i do know that it’s kinda skewed / tilted on the ‘care’ side, (i knew u’ll think that i didnt appreciate what i have now etc bla bla bla..) i’ll try to learn to appreciate it k.. and please note that ‘overcaring is equal to naggy’ stands valid.
