BlueBug Update

I have released an update to BlueBug today that addresses the following issues that were brought up in comments:

  • v1.1 - 9/9/2008 - RELEASED
    1. Added a line to the config.php to limit registered users to posting. Add $config[registered] = 1; in your config.php file to only allowed registered users (if upgrading).
    2. Added a last insert id function to the Database class.
    3. Administrators now get emails when new tickets have been added.
    4. Assign to list for tickets now properly displays all users.
    5. When a user is assigned to a ticket, they are notified by email.
    6. Priority # changed to text for easier reading.
    7. Users are now emailed when their ticket is closed, if they are registered.
    8. There is now a user administration area in the admin panel.

Google Chrome

I have to say this is one of the niftiest features I’ve found so far in Google’s Chrome:

CentOS w/out Yum

Took me about 20 minutes to figure out why this wasn’t working when installing yum:

After you follow the instructions at http://wiki.centos.org/TipsAndTricks/BrokenVserver You get to the part where your trying to install rpm-python. This doesn’t work quite as you’d hoped.Â

Error:

# rpm -Uvh rpm-python-4.4.2-48.el5.i386.rpm

warning: rpm-python-4.4.2-48.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

error: Failed dependencies:

        rpm = 4.4.2-48.el5 is needed by rpm-python-4.4.2-48.el5.i386

So clear all the other RPM’s you installed, download these three from the repository (varies if your using 64 bit or i386)

sar command

I’m always trying to find a good method of monitoring system performance and logging it, but today I ran into a rather strange issue that I couldn’t find on google.

sar 0 was returning high idle percentages:

# sar -u 0

08:17:29 AM       CPU     %user     %nice   %system   %iowait     %idle

08:17:29 AM       all     18.11      0.01     11.66     70.22    3549.42
running top didn't produce 3.5k % idle and in fact the system was nearly 98% idle.Â
The quick fix is to simply run
yum update sysstat
That fixed the problem immediately on the box I was using.
Hope this helps someone else.

ifconfig & Netmasks

Whenever moving IPs around on servers I always find myself looking up the hex for a netmask.

Ever run into this

$ ifconfig

inet xxxxxxxxxxx netmask 0xfffffff0 broadcast xxxxxxxxxxxxxx

And need to know what the fffffff0 was for Here it is:

Dotted Decimal Hex Number of Addresses
255.0.0.0 FF000000 16777214 (16777216-2)
255.255.0.0 FFFF0000 65534 (65536-2)
