If February 22, 2011

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don’t deal in lies,
Or being hated, don’t give way to hating,
And yet don’t look too good, nor talk too wise:

If you can dream–and not make dreams your master,
If you can think–and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;
If you can bear to hear the truth you’ve spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build ‘em up with worn-out tools:

If you can make one heap of all your winnings
And risk it all on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breath a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: “Hold on!”

If you can talk with crowds and keep your virtue,
Or walk with kings–nor lose the common touch,
If neither foes nor loving friends can hurt you;
If all men count with you, but none too much,
If you can fill the unforgiving minute
With sixty seconds’ worth of distance run,
Yours is the Earth and everything that’s in it,
And–which is more–you’ll be a Man, my son!

–Rudyard Kipling

Upgrading Cisco Linksys Wireless Router Firmware (WRT54g v5) November 4, 2010

este post no tiene nada que ver con virtualizacion.    Me toco ser de aquellos que tenian acceso a internet por telefono (uuuuuuuhhhh hace tiempo de eso, de ahi viene mi cuenta de AOL), luego probe el “broadband” de Cablevision 😉

tomamos la decision de cambiar luego la conexion con esa empresa telefonica que domina el mercado en Mexico (si lo reconozco, estoy enriqueciendo a Slim!!!)  . En fin, como parte de tener seguridad en la conexion, y publicar wireless en la casa, desde que estaba con Cablevision adquirimos un Router Cisco Linksys (modelo WRT54g v5), el cual hace su trabajo de manera increible.    El tema es que desde que por alguna razon, mientras no este conectado a la VPN, los videos de YouTube en ocasiones se trababan, en ocasiones se ejecutaban bien, en ocasiones ni siquiera empezaban (por supuesto que no podemos vivir sin YouTube cierto??).    Probe con todo lo recomendado aqui en el portal de soporte de YouTube (o si, tienen uno!!!) pero sin exito.

Quitamos el router y voila!!!   los videos se visualizan sin ningun problema. Asi que identificamos el issue, algo tenia el router que no permitia ver los videos en YouTube.   Asi que me fui a investigar el tema del router. Resulta que viendo los release notes de las actualizaciones de firmware, encontramos el issue!!!  (Resolves issues with certain Internet video streaming), asi que manos a la obra, habia que actualizar el firmware, y asi es como lo hicimos:

– Lo primero que se tiene que revisar, es que modelo y version se tiene del router Cisco Linksys, y esto se obtiene si se mira la parte inferior del router , para ello, la imagen inferior muestra un ejemplo del modelo y version:

modelo y version

en mi caso, tengo el modelo WRT54G, version 5.

– lo siguiente es bajar el update de firmware, para ello, tendrian que ir al siguiente link: http://homesupport.cisco.com/en-us/wireless/lbc/WRT54G. Ahi seleccionan el modelo y version, y proceden a bajar el software.

– Recomendacion: antes de proceder a realizar el upgrade, es recomendado realizar un respaldo de la configuracion del router, para ello ir al menu (desde la interfaz web de administracion) Administration – Config Management – Backup – Config.bin. Hay que guardar este archivo en nuestra equipo.

– Upgrade el firmware. Desde la interfaz web de administracion, ir al menu Administration – Firmware upgrade . Ahi escojan el archivo que bajaron anteriormente. Y presionen upgrade (una vez que el proceso se inicia, no presionen ningun link en la interfaz, solo esperen a que el upgrade termine.   y por ultimo, verifiquen que se realizo el upgrade (en mi caso, tenia version 1.0.0, y despues version 1.02.8).

upgrade linksys

y al finalizar, incluso me cambio el logo a Cisco 🙂     (ahhh, y ya puedo ver videos en YouTube usando mi Wireless Router, y no el de la empresa que provee el servicio de Broadband)

still around….. November 3, 2010

Que tal, ha pasado un buen de tiempo desde que publique mi ultimo post en este blog

eso no quiere decir que haya perdido mi pasion por la virtualizacion, es solo que el trabajo y los viajes no me han permitido dedicar un espacio a mis cosas personales (este blog entre ellas)

pero en fin, esta semana tengo un respiro (minimo), asi que espero al fin publicar algunos posts que he tenido en “draft”

ha sido tanto el tiempo que me he “desconectado” de la comunidad, que tengo acumulados casi 2000 posts por leer dentro de la comunidad de VMware,  puf!!!!!  tanto asi que me perdi muchas de las noticias del VMworld (al que recien he obtenido acceso)

solo queria decir, I am still around…….

System Administrator Appreciation Day July 30, 2010

pues se llego el ultimo viernes de julio, y por ende, es el dia de “celebrar”

http://www.sysadminday.com/

aqui un ejemplo de lo que se lleva a cabo en un datacenter ;D     (deberian echarle un vistazo a lo de unified fabric!!)

Mexico 1 – 3 Argentina June 28, 2010

nada que ver con virtualizacion, pero pues no puedo dejar de hacer notar algunos comentarios acerca de este partido:

– Primer gol de Argentina, por obvias razones los jugadores de Mexico (todos) se van en contra de los arbitros.

– Segundo gol de Argentina, todos los arbitros se van en contra del jugador de Mexico (es una broma sarcastica, digo….)

– Aunque parezca increible, Adolfo Bautista corrió 5.297 kilómetros y Óscar Pérez 5.522, de acuerdo con la FIFA.

– La alineacion de Mexico nada tenia que ver como la que jugo (en grande) contra Francia.

En fin, solo falta poco para el 2014, en Brasil!!!  Espero que respeten a la nueva ola de jugadores

Mexico 2- 0 France June 17, 2010

este no es un post de virtualizacion, solo queria expresar que el dia de hoy Mexico a jugado un gran partido, y por primera vez, ha derrotado a Francia en un Mundial.   Vamos Mexico!!!

I am back!! May 17, 2010

bueno, finalmente despues de bastantes dias fuera del pais (en Damasco, Siria); estoy de regreso, y con las pilas recargadas!!!   — si estaban preocupados por mi persona, estoy bien 😉

asi que esperen nuevos posts que tengo por ahi pendientes de publicar

Saludos

my VCP kit for vSphere has arrived!! March 22, 2010

n ocasiones simplemente se tienen momentos de felicidad, que no sabes como compartir.

Finalmente mi kit de VCP on vSphere ha llegado, y aqui una muestra de como se ve (o si, VMware ha cambiado los colores!!)
