If It Scares You: Cisco ASA 5510

Posted by David  •  Aug 31st, 2014 12:37:34 am - Subscribe | Mood: good | Music: FF IV Orchestra

This is a new type of entry, much like my Linux postings that I have recently been doing, but in these blogs I will be posting about things that made me uncomfortable, but I did them anyways. Success's & failures.

Well most of you know me as a web developer, but I do other things than web dev. In this past year I have taken myself outside of my comfort level and broaden my knowledge in other areas.


"If it scares you, you should probably do it."


This week I was asked to open a specific port on an Cisco ASA 5510, and also configure a Windows Server to adhere to that port on the ASA. I am unable to get into specifics but I can tell you that this was outside of my scope, but I welcomed it.

Success
That day (Thursday) I successfully con figured the server to listen to the non-traditional port and also configured the router allow the broadcasting of it. After a reboot of the server and an outside internet connection I was able to establish a connection. SUCCESS!

Issues
The next day I received notice that certain users were not able to connect to certain shares on the server. To top it off one of them was in a upper level position. EEK!

Solution
After finding the issue, and finding the solution I relayed my concerns to my sysadmin and he was able to get the disk share re-established. At which point I simply remapped my end users on the client ends. (not all had to be remapped)

I guess in the end, the configuration issues that I made to the Cisco ASA 5510 (router) and the reboot of the server was not my doing, but the fact that I was able to get the connection re-established was.

I embrace change, tasks like this regurgitate me. In the mean time I plan on continuing my knowledge with the ASA and seek other tasks as received. It is in my hopes to one day be a full stack administrator, in the mean time...let's all get out of our comfort level, and do something that scares us.

If it scares you, you should probably do it.

Today I was mentioned on the Daily Tech News Show podcast for August 27, 2014. I submitted a press release regarding Seagate is now shipping an 8 TB 3.5-inch hard drive with a SATA 6 gigabit-per-second interface.

I really enjoy this show, and not all the links I submit to the show are read or mentioned, but I really enjoy sharing content with the masses as you know by all my entries. happy.gif

Apache Web Server Crashes on High Load

Posted by David  •  Aug 24th, 2014 10:31:54 pm - Subscribe | Mood: good | Music: No Music

Need to send traffic to your Apache Web Server, in hopes that you will not bring it down by HTTP or ICMP request? Well read on.



Well this is unique entry, recently a friend and I we're bench testing a couple servers on different nodes using the Apache Benchmark Tool. In our findings we noticed that 2 of the domains that we tested feel to they're knees due to memory issues. Now then, in no way do I condemn black hat conduct but sometimes the only way to protect your OWN servers is to use penetration testing tools to stress the server.

Now, there is a plethora of software that can do this locally on the server or for remote usage, but for this entry I will refrain from that.

I recommend that you take a look at my friends blog on how to protect yourself from an EVASION of traffic.
