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.

Uh oh …

My other boss, R, wanted a new site added to the server down in Miami. No problem, it's not something I haven't done before. So I go through the steps needed to add the site, and in this case, the site requires its own IP address (because of the group its in). Not a problem—just pick one of the currently unused addresses, add it to the network interface and there we go. Done, I log out to do other things (like post pictures of Casa New Jersey).

Well, there's a slight problem. The Miami server is also the one that my sites are stored on, and when I went to log back in when trying to post the previous entry, I got an error I've never seen before:

ssh_exchange_identification: Connection closed by remote host

Uh oh.

I can pull up websites, so that's fine. But ssh? FTP?

Nope. Can't log in.

I make multiple attempts, from several different locations across the Internet, trying to log in but the server is not letting me log in.

I do a Google search on the error, and it's heartening to see that this isn't a rare problem at all. But further reading doesn't reveal a solution to my particular problem. No, I didn't change /etc/hosts.allow or /etc/hosts.deny and it was working earlier when I added the site and IP address—

IP address. I added an IP address to the network interface.

And I'm guessing that was enough to throw sshd into suspicious mode and refuse logins.

Well, fine. I knew the solution—restart sshd (and the FTP server—apparently that was having fits too). But how? I can't log in.

Ah, but there is the power pole. Log in to the power pole (through a <cough> <cough>control panel<cough> <cough>) and power cycle the outlet the server is on. Not a great solution, but hey, it'll save me a trip down to Miami.

So I call C, who is responsible for the power pole setup. But well … there's a snag. Since the last debacle the IP address of the power pole was supposed to be updated, but he wasn't sure if it was.

Great.

But C needs to get with our network engineer to actually determine that, so until tomorrow (well, later today) no one will be able to log in to the server.

Sigh.

Obligatory Picture

Obligatory Links

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.
