New issue online
By Brad Shimmin at 07:23 PM
Hi folks. Sorry for the vacation from posts here. Coincidentally, I'm in the midst of a vacation. I'll be back in the midst next week. Until then, you're welcome to check out the first installment of our April 3rd issue of Network Computing. This issue features a review of Web Services Platforms by Lori MacVittie. You can also check out a number of extras (an audio interview, special techquiz, and test applications you can play with) on her Project Blog.

Here's a quick rundown of the rest of our issue stories and online goodies.


As always, you can grab the entire contents of the new issue from our RSS feed, or you can browse for stories here.

Interference
By Lori MacVittie at 04:04 PM

If you've been following along you'll know that we recently moved our infrastructure over to our Cisco switches/routers.

One of the things we've been doing is implementing our management network - hooking into the APC UPS and getting all the management software to remotely administer the machines if necessary. So that means each machine has 3 network connections: a primary, a secondary for failover and the management network. Well, the management network was set up but not completely configured. The interfaces are trying to DHCP and we don't have a DHCP server on that management network. So the interfaces - a PPP connection - ends up with the default "I can't get an address" address.

This was causing headaches. For some reason, our DNS server decided that this "no address" address was its primary connection and was returning it in response to queries for it IP address. Since this is also our ADS server, you can imagine the problems on the network just from that. Then to add to the problem our mail server did the same thing, putting both of them on the same address and wreaking complete havoc throughout our network.

I shut down the management interfaces and rebooted (cause rebooting Windows is the best fix for problems) and voila! All is well again.

Next up: CRM
By Lori MacVittie at 08:01 PM

Having finished up testing Web Services platforms now we're getting ready to test CRM solutions for NWC Inc.
This is a cool review, because we'll be keeping the winner of this review as our CRM solution.

We've been imaging our disks to get ready for the review as well as unboxing our six new servers that will serve as additional infrastructure for the lab.

Our DNS server was having problems resolving addresses, and the issue turned out to be an issue with an access list on our Cisco router. After a frustrating half hour of checking and rechecking configurations, we finally had connectivity back and were able to resolve addresses again.

Then, because we hadn't had enough challenges in the last few days, we had to find out why our NetBotz was spewing e-mail to a nonexistent user @nwc.com. After finally remembering what the uname/password was for the device, we were able to ascertain that a single field was misconfigured with a bad user name. We changed that, but found that the device was still spewing forth an unacceptable number of alerts - all of them notifying us that a set of external sensors were not responding. Probably because they don't exist. :-) So Steve changed those settings and finally our NetBotz is back online and acting normally again.

Special Top 11 List
By Brad Shimmin at 04:54 PM
Sometimes our twice-monthly Last Mile feature in Network Computing just won't hold all of the great ideas we receive from our readers. In this case, we just couldn't hold onto the following Top 11 List, which harkens back to February's SQL server security problems. We hope you enjoy it. Top 11 excuses overheard at Microsoft's security response help desk.
  1. Windows 2000. XP. NT. SQL. Who can keep all those server thingies straight.
  2. Everyone knows that you have to install the really important patches twice.
  3. It is pronounced "sequel". If you don't pronounce it right, we can't help you.
  4. I'm sorry, you'll have to wait for the sequel to find out if that issue gets resolved.
  5. I already patched it twice before. Isn't that enough? Jody Marc Cohn
  6. I called our internal tech support and they haven't applied any packs, so it must not be a Microsoft issue, must be a customer issue.
  7. Slammer Worm? I'm sorry, we don't respond to calls regarding health problems at correctional facilities. That's more of a hardware issue, anyway.
  8. This wouldn't have happened, if you were using Microsoft's Internet Security and Acceleration server.
  9. S-Q-L server? Can you spell that for me?
  10. We only load the odd-numbered service packs, wasn't that an even number?
  11. Oh no, not another TREMORS movie!
Special thanks to Dave Baldwin, Douglas Lancaster, Paul Godfrey, Linda Anders, Steve Warren, Jerry Reusch, Gary Sterenberg, Robert Pilz and Corinne Kroening for their submissions.

Want more? You can check out our current Top 11 list, or you can submit your list items for an upcoming issue.

Hot Time in the Old Town
By Tom LaSusa at 06:36 AM

Well, we had a heck of a day yesterday.

Temperatures in the NWC Inc. lab got all the way up to a high of 86 degrees when I opened the door in the morning. I shut down most of the equipment in the Green Bay Real World Lab section of our facility, and got on the phone with our realty management company. A call to the air conditioning repair guy yielded a friendly service tech in about an hour.

It appears that our air conditioning unit was low on freon, and had iced up. Iced up to the tune of three or four inches of ice. Our service tech, Tom, used the patened Smoke Wrench (a propane torch) to melt most of the ice. Then he recharged the freon, and we were good to go. No more Data Center Sauna for us.

This morning things seems to be working fine. I will keep you posted if anything changes.

Don't search the Web. Search what's said on the Web
By Brad Shimmin at 07:10 PM
With Google.com virtually the only game in town, it's good to see new engines like Teoma* every now and then. So I was really pleased to stumble upon Roogle earlier this year. I played with it a little bit and submitted our site. But I didn't spend very much time with the engine. This past week, the company changed its name (for obvious reasons) from Roogle to Feedster and is hard at work serving up search results not from site spiders but from RSS feeds. With its new name and nearly 14818 posts and over 1309 RSS urls, I think I'll spend some more time there.

The importance of this should be immediately clear. When you publish to the Web, you create two types of documents, those that are meant to be searched, and those that are not (like pages that contain nothing but indexes of stories, for example). By focusing on RSS feeds, Feedster bypasses this problem elegantly, letting the searcher look only for documents that are deemed readable, useful, even desirable. Of course it can return results as RSS feeds.

*I highly recommend Teoma, BTW. This engine not only organizes results by popularity, it presents meaningful collections of relevant sites, allowing users to quickly refine and re-refine a given search query. Pretty spiffy.

Syslogging away
By Lori MacVittie at 02:12 PM

We decided to set up a dedicated syslog server to aggregate messages from the routers and switches, so after a load of RedHat onto a litlte 1U server and the editing of a few configuration files our syslog server is up and running and doing its assigned duties.

Our addition of SQL server went well - of course, all we did was install the thing so far. We're holding off on actually replicating data for a month or so - we've got an upcoming review that it just so happens will take care of that chore in real time for us. ;-)

Sendmail Bug, Lessons Unlearned
By Tom LaSusa at 11:45 AM
We've just posted an online-only BuzzCut about Sendmail, the predominant SMTP e-mail server program on the Internet today. Last week, it was publicly revealed to have another security bug -- and a pretty serious one at that.

New Site Content
By Tom LaSusa at 10:57 AM
Afternoon Everyone,

The second half of the March 5, 2003 issue is now online. This week, David Joachim returns "On Location" to Children's Hospital Boston, where a data-mining application originally conceived to forecast staffing and supply needs now helps them spot bioterrorism outbreaks. In addition, we've got a review of Web security proxies --a.k.a., Web application firewalls. Plus plenty more, including some Sneak Previews, BuzzCuts and of course our Last Mile.

As always, you can grab the entire contents of the new issue from our RSS feed, or you can browse for stories here.

Woo hoo!
By Lori MacVittie at 06:50 PM

I just happened to ping one of our class C's the other day out of frustration and guess what? Something responded. Hmmm...

Instead of adding a route, dudes at our ISP just assigned one to the DSL router. Without mentioning it to us. Nice.

After an hour spent reconfiguring our router, voila! We are live. And after two days of ripping out cables and putting in new ones we are almost ready to go. We're paying careful attention to cable management this time. We've even gone so far as to color code them - blue for primary network connections, another color for secondary, green for management and another for our IP based KVM.

We'll also be adding some databases to our infrastructure. While we're running as close to a real world production environment as possible, there are some things we require in order to support our editorial goals. DB2 is working fine, but we need to be able to test on multiple databases, so we'll be adding SQL Server shortly and, hopefully, one more RDBMS in the next few weeks. We'll replicate data between them to synchronize our corporate data and this should offer a bit more flexibility on the editorial side as well as better representing the real enterprise, which often runs at least 2, if not 3 or more, databases.

So cross your fingers - if all goes well tomorrow we'll be live again by the end of the day.
