If your carrier doesn't allow 10 digit dialing for local numbers, you are probably pretty annoyed that you can't just hit the redial button on those missed calls. It's possible to rewrite these dialed numbers in your phone system, but I wanted to do this on my Cisco 7961 IP …

I've dealt with a few servers that have long lived popper (POP3) processes. These processes should be closed once the connection is closed, but they occasionally hang around. Once they get in this state, they will never close on their own. After a while, hundreds of these processes will just …

If you're using policy-maps on your Cisco Catalyst switches to handle rate-limiting, you may have noticed that on some models, the show policy-map interface command does not seem to work. The CLI accepts the command and returns properly formatted output, but the output is all zeroes. There is no information …

One of the beauties of using a Linux-based Mail Transport Agent (MTA) like Sendmail is the ability to pipe mail into programs. You can use this in conjunction with a filtering application like procmail, with a custom application that collects data about the email, or anything else you can imagine …

After cracking open a brand new Catalyst ME3400G, we weren't able to get it upgraded to the latest version of software. In fact, we couldn't even ping anything on the local subnet.
In order to use Cisco's Metro Ethernet switches, it's important to understand the new concepts that are introduced …

I use snmptrapd to catch SNMP traps and then put them into a MySQL database using a pretty generic trap handler. This gives me the opportunity to generate such useful information as:
> SELECT HOUR(time) AS "hour", COUNT(*) AS "bounces" FROM snmptraps
WHERE hostname = 'XXX' AND time > '2011-07-25'
AND trap_oid …Posted on in Networking

I was recently part of a discussion regarding whether or not lowering the
load-interval on a Cisco router or switch interface from the default of 300
seconds had an impact on performance.
Both sides made good points, but
both were based on assumption and conjecture.

A really interesting discussion has been going on in the LinkedIn IT Architect group. If you aren't a member of the group, I highly recommend you join. The question that fired off the discussion was, "Is 'the cloud' just another name for a hosted / out-sourced (web application) service? If not …

Historically, the RPMforge repository has aimed to create add-on RPMs for RHEL, CentOS, and Scientific Linux. Although their goal was not to replace base packages, avoiding that has not always been possible. In mid-November 2010, RPMforge created the rpmforge-extras and moved all packages that replaced base packages into the repository …

"Keeping a meeting interesting is a problem that often hurts team leaders who are trying to motivate sales staffs."
Although Tom Donnelly's Inc article is really targeted at sales meetings, I think it has some points that are relevant for all managers. Keeping team members engaged in a meeting is …

My wife uses a Canon FS100 for taking home videos of the kids. If you aren't familiar with it, it's a fairly light-weight camcorder that uses SDHC cards rather than tapes. The only real grievance I have with it is that the video codec it uses is not compatible with …

A while back, I sent an email describing the strategic management process. Although the email was written for an internal audience, it's generic enough to be reproducible here...
Strategic Management is a five step process:
