Any one who has tried to run Cisco’s ASDM (ASA Security Device Manager) with an IPS unit installed and running probably already know where this is going. Under Configuration and IPS your a provided a link that connects the broswer windows (ASDM) to the management interface of the IPS SSM module for the ASA. From there you are presented with ASA like login which is where the problems begin. If your are running the default java config the IPS screen will crash stating that you do not have enough memory allocated for java. In both Windows and Linux the solutions for this are pretty straight forward. In OS X however much searching and digging did not reveal the magic spot to change the memory settings. Thats where I come in. Read the rest of this entry »

I’m going to make this quick and to the point. Look for details in my upcoming post “Cacti the killer monitoring app? I have now installed Ubuntu 7.04 Server and Cacti in some form more than 18 times in the past two weeks. Most of those have been a frustrating failure! I am by no means a *nix god so most of my problems probably had to do with not knowing the ins and outs of the Ubuntu OS. My failures can probably also be directly attributed to a lack of 7.04 install guides for cacti. So with so many failed attempts and 3 Fully successful attempts both on HP hardware, Dell Hardware and a VM Ware server Virtual Machine I am going to post my 8 basic steps to making cacti work.

Not much to say here. This points to Cisco’s site. I just got tired of googling it. Enjoy.

From a Network Engineer’s point of view this is exactly what is wrong with todays home networking methodology. Every night when I get home from work I follow the same rough routine. I plop down on the couch power on my laptop and connect to my home network via wireless. After doing so I check my connection logs for the day to my AP, my overall bandwidth usage via PRTG and my syslog server messages from my firewall. I do this to ensure that all is well on my little spoke of the internet. But I know for a fact that those of us who perform this little daily dance are in the minority. Instead what you get is scores of people purchasing wireless routers and just throwing them on their cable or DSL modem and going on with life, like they didn’t just leave their front door open with a big neon WELCOME HACKERS sign over it.

Whether you have been a part of the networking community for years or are stumbling across this post in a search for a way to identify how much traffic your server or network connection is using, Paessler Router Traffic Grapher is for you. Historically if your were trying to get a handle on traffic, CPU utilization, Memory utilization, Process Count and countless other SNMP counters over a historical period you would use MRTG, HP OpenView, WhatsUP, Orion or CiscoWorks. But with all those solutions you run into one or both of the following problems. Read the rest of this entry »
