I recently needed to tag the first 5,389 messages in a mailbox using Mutt. This is much easier than you might think.

1. shift-t - By default, the command to tag messages based on a pattern is bound to shift-t. If you've changed this in your muttrc, use whatever you've bound …

You've certainly noticed when look at individual BGP routes on your Cisco routers that the route is advertised to specific update-groups. It isn't obvious from that output just what those update-groups are.

Router#show ip bgp 8.8.8.8       
BGP routing table entry for 8.8.8.0/24 …

If you need to comment something out of your .vimrc, start the line with a double quote (").

"autocmd BufRead *.xml :source ~/.vimrc.xml

It's embarrassing to admit how long it takes to find the answer to that question.

When I upgraded to OS X 10.7 (Lion), I started using the built-in IPSec VPN client rather than Cisco's VPNClient. I experienced problems immediately. At first it appeared that the connection was being made, but no traffic was passing. When I tried pinging by IP address, I found that …

I released a new version of my Google PageRank Tool for WordPress last week. Google recently changed the URL for PageRank information which necessitated a change in the plugin. The new plugin has been tested with WordPress 3.2.1.

You can download the latest version of the plugin from …

This is an annoying problem:

Switch#write

Switch#dir nvram:

Cisco Catalyst switches simulate NVRAM on their flash. Once in a blue moon, this simulated NVRAM will become …

If you're a frequent user of GNU screen on your Mac, you are probably tired of using ctrl-a [ to enter scrollback mode. Adding the following lines to the .screenrc configuration file in your home directory in order to scroll with your mouse:

defscrollback 5000
termcapinfo xterm* ti@:te@

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 …

If you see an error like the one below in your Cisco ASA log files, check with the other end and make sure your transform-set matches.

QM FSM error (P2 struct &0xd7fed708, mess id 0xcc86fb64)!

The QM FSM error message usually relates to a configuration mismatch. Although checking the crypto …

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 …

Why is it always a pain to find this stuff in the documentation?

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 …
