George posted an excellent blog on hostname nomenclature a while back, but something we haven’t discussed much in this space is a naming convention for the BIG-IP configuration objects. Last week, DevCentral community user Deon posted a question on exactly that. Sometimes there are standards just for the sake of having one, but in most cases, and particularly in this case, having standards is a very good thing. Señor Forum, hoolio, and MVP hamish weighed in with some good advice. [app name]_[protocol]_[object type] Examples: www.example.com_http_vs www.example.com_http_pool ...
July was a busy month. I took the first three weeks off and drove much of what’s left of the “mother road” on Historic Route 66.with the family, our Ford Expedition, and way too many nights in our 31’ travel trailer. Great memories and stories for a lifetime out of that trip. I was home long enough to unpack, do laundry, and repack for a great week in Chicago with the DevCentral team. On Monday, we had a great time diving in to F5 technology goodness with the MVPs (and hoolio and Chris Miller!) at the Thinkubator. It was a...
DevCentral community member geffr had a problem. The BIG-IP Application Security Manager module logs to the local3 facility but he needs to send them to the local7 facility on a remote server. Before giving up entirely, he posted to this thread in the Monitoring & Management group forum, where user nitass helped him jump through the syslog-ng hoops (click here for tips & tricks on syslog-ng) to the working solution posted below. It’s pretty straight forward. Define a template, a filter, and a destination, and then put the pieces together in a log statement. ...
This has been a perplexing issue for many users. How do you introduce an intermediary (LTM going forward) between client and server when in the same network segment? It’s easy when the LTM sits at gateways, but within a segment, it doesn’t work that well without some help. Why? Well, with tcp-based connection-oriented protocols, a handshake (consisting of a client syn packet, a server syn-ack packet, and a server ack packet) sets up the connection. When you introduce the LTM, a problem arises: Client –> syn –> BIG-IP BIG-IP –> syn-ack –> Client...
The BIG-IP WebAccelerator joins ranks with the Local Traffic Manager and the Global Traffic Manager as modules that received some major upgrades with version 10. Not familiar with the WebAccelerator? Affectionately called WA in these parts, the WebAccelerator is "an advanced Web application delivery solution that provides a series of intelligent technologies that overcome performance issues involving browsers, Web application platforms, and WAN latency." That's straight from the glossy, I couldn't say it any better than that. The DevCentral team has been filming a documentary series (Real IT, check it out!) on speeding up the site for our users in...
Welcome back for another episode of the ABC's of NSM. What's NSM you say? We'll go with Network and System Management, but you could throw Security in there as well. We'll work our way through the alphabet over the next several weeks looking at tools and concepts along the way for all the administrators out there. By the way, you can thank Joe for the format & Don for the title (I couldn't for the life of me come up with one.) Today's letter F is for FreeRADIUS, an open-source package allowing administrators to host a RADIUS (remote...

By the way, you can thank Joe for the format & Don for the title (I couldn't for the life of me come up with one.) Today's letter A is for arpwatch, a utility that keeps track of mac/IP pairings. This has obvious upside for making sure IP's aren't switching in non-DHCP...
You know it, and I know. At the end of the day, those who own the box are on the hook for failures. Said owners, therefore, are not so eager to let you on the lot to kick the tires, and they certainly are not going to let you take a test drive. I get that. Risk is scary, and consequences are real. Enter partitions. First introduced in version 9.4, partitions allow the BigIP administrators to grant twofold access to the system: what objects can be accessed, and what the user with rights to that partition can do with those...
Every now and then someone pushes out a utility that just makes you yell "YES, that's exactly what I never knew I always wanted." BCV, or BigIP Config Visualizer, is one of those utilities. You supply a bigip.conf file, and BCV presents you with an image file for every virtual server defined in the config. Your images can be exported in jpg, png, or svg format. Exporting via svg gives you the ability to open (and edit) the image in Visio, which is pretty handy. Here's a snapshot of a lab vip: F5er Micheal Thompson cranked this out...
