Custom Sizing Your MMC RDP Console

Following on from yes­ter­days post I was look­ing at some of the options and real­ised that you actu­ally set the size of you RDP console.Since I use a Mac Book Pro with a wide screen the stand­ard res­ol­u­tion are not very help­ful, and I like to have fixed size win­dows, chan­ging them to use the avail­able width is a good thing™

Multiple RDP Consoles — Who Knew ?

I have been work­ing with Windows folks for a long time, and I have not seen this tool used before. As a net­work­ing guy maybe I missed it.
I often deploy a num­ber of Windows serv­ers to mon­itor and man­age net­works (typ­ic­ally with open source and Ciscoworks). I recently dis­covered the MMC Snap-​​​​in for Remote Desktops which makes my life simpler […]

Flush DNS Cache on MAC OS X

Mac OS X  —  Clearing or flush­ing the DNS Cache

Once you go to a Web site, or do any DNS lookup, the IP gets cached for quite a while. This becomes a royal pain if you’re a sys­tems admin­is­trator who is in the middle of migrat­ing domains from one server to another. Executing the fol­low­ing clears the cache, restarts the cach­ing daemon, […]

Cisco Application Control Engine (ACE) — Introduction and Comparison With F5

My new interest of the moment is the Cisco Application Control Engine or ACE mod­ule. I have just received a pair of them and plan­ning on start­ing the con­fig­ur­a­tion in the next couple of days. So per­haps some dis­cus­sion on the ACE is in order, and why I am con­sid­er­ing using both F5 LTM AND the Cisco ACE in this network.

iTerm and Dynamips — Write to All Terminals at Once

I am often find myself need­ing to stop, make a con­fig­ur­a­tion change to Dynagen, and then restart. To make sure I don’t miss any­thing I go to every screen and write the configuration.

In iTerm, there is the abil­ity to send the same com­mand to all screens at once, excellent!

Suspending and Resuming Dynamips

As someone who travels often, and always look­ing to make use of the travel time, I was pleased to find that I can sus­pend and resume the Dynamips routers. This saves me bat­tery on longer trips, or lets me have more CPU when I run­ning other applic­a­tions such as Parallels /​ VMware to give me some Microsoft Visio joy. iTerm ses­sions are not ter­min­ated by doing this, they just don’t show any data until you resume the sessions.

Dynamips and the Leopard Terminal

I wanted Dynamips to act more like the way I think and it keeps on open­ing mul­tiple ter­minal win­dows but I like to use iTerm.

Configuring iTerm for Dynamips

To get star­ted with my lab faster I use iTerm to pre­pare a full set of pos­sible ses­sions. This post walks through how to do this which should help you to get star­ted faster. Also some key­board shortcuts.

On Layer 2 Access Designs and MPLS

I look­ing closely at Data Centre Designs at the moment, and been con­sid­er­ing whether a looped tri­angle or a looped square is the best for edge switches. I find it dif­fi­cult to detect a dif­fer­ence that makes a clear pur­chas­ing decision. So I sat down to think about this. I did some pic­tures and thinking.

Unzip Cisco IOS Images for Dynamips

I have a dir­ect­ory ‘dyn­alab’ in my ‘Documents’ where I have put ALL my Dynamips /​ Dynagen related files. I cre­ated a dir­ect­ory there which has all my IOS images, this makes more sense to my mind. Makes it easier to backup.

Dynamips on a MacBook Pro

I am doing some proof of concept for an MPLS data centre and did some­thing I have not nor­mally done. I used my MacBook Pro to run Dynamips /​​ Dynagen. I am very pleased with 9 3640 routers run­ning Enterprise Plus, and 2 2611 Routers with IP and run­ning less than 60% CPU across both cores

This means that I have still have […]
