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.

More tunneling issues

At the end of January, I called out to the Lazy Web for advice on how to get a Cisco 2611 to authenticate a PPPoE connection and well, it's finally working (with no input from said Lazy Web):

interface ATM0/0
 description XXXXXXXXXX Secondary Internet Connection
 no ip address
 no atm ilmi-keepalive
 pvc 6/42
  encapsulation aal5snap
  protocol ppp dialer
  dialer pool-member 1
 !
 dsl operating-mode auto
!
interface Dialer0
 description Authentication Happens Here
 ip address XXX.XXX.XXX.XXX 255.255.255.0
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp chap hostname XXXXXXXXXXXXXXXXX
 ppp chap password 7 XXXXXXXXXXXXXXXXXX
!
dialer-list 1 protocol ip permit

But I do have to admit some confusion over why it suddenly started working. I had this configuration pretty much in place by the end of January but I just couldn't even see the customer's router by DSL (which, as you can see there, is a backup connection in case their router's primary connection goes down). It's hard to debug this since you don't even see the traffic unless you pass an authencation request through the physical lines owned by The Monopolistic Phone Company, and because the radius authentication server wasn't getting any requests, that meant that our Cisco router wasn't seeing any DSL traffic from the customer.

Very annoying.

Then earlier this week BAM traffic suddenly was getting through. It's almost as if The Monopolistic Phone Company took their own sweet time in actually enabling the DSL circuit on our customer's phone line.

Good thing too, since their current provider is having issues with connectivity (and twice this week I've had to reprogram their router's primary IP address). Now the issue is why the router is prefering the DSL connection over their primary connection (which is the exact opposite of what is supposed to happen).

Update on March 2nd, 2006

I found out why why the DSL was being prefered over the Ethernet connection.


Stupid student tricks, now that the statutes of limitations has expired

When I saw the video of Atlanta students driving the speed limit (link via Instapundit) I was reminded of the time I participated in such a stunt about a decade ago.

It wasn't consciencely planned; it just more or less happened, and it wasn't on an interstate highway (or any type of highway) but on a road (major road, but road nonetheless). There were three of us, each in our cars, spanning the road all driving the speed limit and watching (much like in the video) the traffic piling up behind us. Periodically, one of us would slowly creep ahead (which is something the students above didn't do), but not so much as to let anyone pass us, and watch as all the cars behind us would start shuffling, attempting to get behind the slightly faster car. The one driving just slightly faster would then slow down to match speed again, and someone else would start to pull ahead, and the car shuffle would start yet again.

We found it very amusing, and I'm surprised, it being Lower Sheol and all, that we weren't forcibly shoved off the road and shot.

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.
