I’ve been a Linux Administrator for about 6+ years now and I love Linux now more then I did then. Though I do not particularly like being a Admin or an Engineer any more. I actually prefer being an Architect or a Systems Programmer. As bad as the economy is right now, there are quite a few jobs out there. Especially for Linux System Administrators/Engineers!

The problem these days, is that the Linux SA’s which WERE and ARE still highly regarded. Are being flooded with LAZY admins that have and continue to flood the Networking and Microsoft world. In the past year, I have met a few interesting Microsoft Engineers who actually knew the product very well. Besides the normal right click and actually knew how to script and automate ( This baffled me ).

So here’s the issue I’m trying to resolve. This worked before. Now I authenticate successfully via ssh, but get the error message you’ll see below. Any takers?

Login and leave your answer in the comments section. If your solution works I’ll give you credit here, and put you at the top of the list for some LinuxDynasty swag!

This has come up on a couple of projects I have been involved in lately. It seems that this is becoming frequently used as a redundancy configuration for Linux-based Oracle Server applications on the network.

 In Cisco lingo this is called an EtherChannel. In Linux-speak it’s called Bonding. The protocol used – as required by the Linux software – is LACP (Link Aggregation Control Protocol).

He guys, I’m here listening to the debate and all I can think about is should I take the time to learn Ocaml. Always seems like there is not enough time in the day to be come an expert in one language to pick up another language. All of my focus has been on python and trying to become a better python programmer.

Today I came across Ocaml, Objective C Meta Language. Now I want to learn that. But how do I continure to improve my Python skills while learning Ocaml????

 

I would love to here your comments…..

This HowTo demonstrates how to configure some basic parameters on your Cisco Router or Cisco Switch running IOS. These commands were run on IOS version 12.4-6.T11. This is the standard stuff that I’d typically put on every Cisco Router or Cisco Switch running IOS in the network. 

**Note feel free to post any questions or comments in the Forums section on this site.

I figured we’ve jumped around a bit, but not shown some basic Cisco information from the low-level up. This HowTo format will appear more often in the future. It will consist of the output from the capture of a real procedure on the router, followed by either diagnostic or configuration commands.

In this case you’ll see the bootup sequence of a new Cisco 1811 router (which is basically the same sequnce as for any Cisco IOS device), then I’ll run the "sho ver" (short for "show version") command. I used "PUTTY" a free download terminal client to record the information below.

I had to create a script that will output every host that has went down in the past day and how many times that host went down and at what times did that host go down and when it came back up in a nice readable format ( Executives who do not know what they are looking at ). Now this is the first release of my script and I do mean first release as I really want to expand it to not just do daily reports from nagios.log but as well as get the archives and any to pass it dates.

I hope you Nagios users who have to send reports to your executives find this script useful but check back soon as I’m going to be adding more to it or even changing it into its own class. As of right now it consist of three functions. The only draw back of the script is that it takes a while to parse the log file since it has to find all the uniq hosts in nagios.log and find only the hard down and hard up events compared to the uniq hosts.

For now I run this script in cron at 6AM and have the txt file that it creates sent to a list of users at 7AM on a daily basis.  Again this is my first revision it will go through alot more and if you have suggestions or you have expanded on this script by all means let me know so I can post it up here or you can become a member and post it yourself. Also if you have request please become a member and ask in the forums section.

UPDATE!!!
Cambid, fixed the regex in the script. It  should now match correctly in all environments!
