WBC 2010 – Day 3

guru — Fri, 06 Aug 2010 15:58:52 +0000

Final for Republic of Rome tonight. This is going to be my last year running the game. I would love to be able to say it is bitter sweet or some such…. But I have just burned myself out. After running it for so many years I just need a break and to be able to enjoy DonCon.

On a brighter note hopefully we can mix in a steak dinner tonight before the final

WBC 2010 – Day 1

Today was my first full day at the WBC. The demo of Republic of Rome went pretty well with some new player interest. The first heat just began with two tables. From what I am told there are a lot of time conflicts this year so we will see what happens for the second heat

SSL Certificate Installation Cisco ASA 5500

This was driving me nuts – I kept screwing up the order. Network Solutions throws you for a loop by giving you 4 different CRT files when you just needed two parts of the chain – so for future reference

More for my own reference – I totally forgot how to do this

Excellent powershell tool that builds a visio diagram based on information it pulls out of Virtual Center – super super handy. Kudos for sure

How to allow active FTP on a Cisco ASA.

This took me forever to figure out for some reason:

class-map inspection_default
 match default-inspection-traffic
!
!
policy-map asa_global_fw_policy
 class inspection_default
 inspect ftp
!
service-policy asa_global_fw_policy global

Netapp: High CPU/NFS Ops – low network input

guru — Tue, 27 Jan 2009 21:21:03 +0000

Troubleshooting note to self

—

High CPU and NFS operations, however network input is low

Symptoms

High CPU and NFS operations, however network input is low

Cause of this problem

Numerous NFS clients continuously send the filer NFS operation requests, but the clients/users may not have permission to access the filer’s data.

Solution

If the output of the filer’s sysstat command displays higher than normal NFS operations per second and higher than normal CPU utilization, and sysstat displays low network input, determine if NFS clients are sending invalid requests to the filer that are being denied. To determine which NFS clients are sending numerous packets to the filer, complete the following steps:

Note: Enabling NFS per client statistics may cause a slight performance impact.

Enable NFS per client statistics:

options nfs.per_client_stats.enable on
To zero the statistics, enter:
nfsstat -z
To display the usage of all NFS clients that mount the filer, enter
nfsstat -l
Investigate the client(s) with the highest usage. Sample nfsstat -l output:
filer> nfsstat -l
10.10.10.1 client1 NFSOPS = 49 (1%)
10.10.10.2 client2 NFSOPS = 47 (1%)
10.10.10.3 client3 NFSOPS = 745 (96%)
10.10.10.4 client4 NFSOPS = 48 (1%)
10.10.10.2 client5 NFSOPS = 50 (1%)

In the sample output above, client3 has the highest usage and is most likely causing the packet storm.
Turn off NFS per client statistics options nfs.per_client_stats.enable off
Investigate NFS clients that show high usage in nfsstat -l output for processes that may be causing the packet storm.

Argh another power supply blown

guru — Wed, 24 Dec 2008 01:12:39 +0000

I came home today to yet another power supply blown. This time in the jukebox just when I wanted to sit down and listen to some tunes. Talk about annoying. After much knashing of teeth I swapped out the PS and things are working. I wonder if the house has some dirty power…
