Cooking 101: 20 Lessons to kick start your cooking skill. I consider myself a decent cook. I don’t make anything overtly extravagent but I always have fun cooking in the kitchen. There’s some good information in these lessons including more efficient ways to do things – for instance I have never chopped an onion the “right” way but the method they describe would be faster.
I’ve written about networked printer insecurities before and I came across another great article called Hacking Network Printers (Mostly HP JetDirects, but a little info on the Ricoh Savins) by Adrian “Irongeek” Crenshaw. Don’t forget that those network printers are fully functioning computers these days and should be treated with the same security measures.
I recently found that the Barnyard process on my IDS sensors were unexpectedly throwing errors in /var/log/messages:
barnyard: FATAL ERROR: Error (The table 'data' is full) executing
query: INSERT INTO data(sid, cid, data_payload) VALUES('5', '9158',
I logged into my master MySQL database server and checked the size of the sguildb data file:
# du -ha sguildb/data.MYD
Oh, there must be a 4G filesize limit. Let’s see how many rows I have in data:
mysql> select count(*) from data;
| count(*) |
| 3719121 |
1 row in set (0.00 sec)
I probably need to bump up the number of rows. This article at the MySQL site helped.
mysql> SHOW TABLE STATUS FROM sguildb LIKE 'data';
That output gave me the rows and avg_row_length I need for the following command. I decided to bump up the max_rows to double what I currently had (2*3719121):
mysql> ALTER TABLE data max_rows = 7438242 avg_row_length = 1154;
Query OK, 3719121 rows affected (16 min 0.57 sec)
Records: 3719121 Duplicates: 0 Warnings: 0
I bought some wireless components to do wireless auditing at work. It’s a bit confusing picking out exactly what you need and what works well so I wanted to make a note of what I got (from Netgate, recommended):
The card worked out well as it contains a widely supported Intersil Prism 2.5 chipset and has two external antenna leads. I was also tuned into a great bootable OS based on KNOPPIX called Auditor. It has 300 some security tools and worked well in performing wireless audits using tools like Kismet and Wellenreiter. Also, wavemon, a monitor for wireless devices, works extremely well for pinpointing the location of wireless devices. In fact, I liked Auditor so much I installed it on the hardrive of the laptop.
Here’s a picture I took of the wireless hardware.
