The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

Spillover from yesterday

Today started out like yesterday ended. I was awaken by a call early this morning because a server I manage was down. I call over to the datacenter to have it rebooted, only to have it still down half an hour later.

Sigh.

Get into the data center to find: Keyboard error. Press <F1> to continue across the screen.

Sigh.

After that, I had to give the new server the old IP address, only it kept refusing to accept the new IP address, saying that some other machine was using it. That's odd, I thought. I could have sworn the old machine was unplugged from the network. And lo, when I checked, it was.

Turns out Smirk had moved the site that was on the old server to one of our servers temporarily, but neglected to inform me of that little detail.

Sigh.

Then a rash of calls and support tickets screaming about email. Over and over again I had to inform our customers that because of the denial of service attack, email got backed up and our email server was having to process a huge backlog of emails just please be patient.

Sigh.

Things calmed down after that.

And I'm not saying anything past that—I don't fancy jinxing myself.


That little routing issue

I also did manage to find a work-around for the little OSPF problem I've been having. What's happening is that on the customer's router, when the T-1 link is up, the routes, including the all important default route, are populated through OSPF. If the T-1 goes down, then all the OSPF generated routes disappear, including the all important default route.

Upshot—if the T-1 goes down, the customer can't see the Internet.

But oddly enough, when the T-1 goes down, OSPF still shows a neighbor connection through the DSL link. But it won't populate the routes.

The work-around? A static default route through the DSL connection but weighted so heavily that the default route through OSPF (in which case goes through the T-1) is preferred if it exists.

So now, the T-1 goes down, the OSPF routes disappear, leaving the static default route over the DSL so the customer can still see the Internet.

It works, but I don't like it.

Obligatory Miscellaneous

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
