  The fbdev driver for x.org's server works with any framebuffer.  :-P

Have you seen the Archos Android tablets? There are 2 of them out,
right now (first hit the market late last year), also with other
models on the way; it looks like Archos is actually behaving as a
good member of the FOSS community, too.

Radio Shack and Best Buy both carry some selection of them in stores,
if you haven't seen them; if you have..., thoughts?

Maybe.

Swapping to flash is often a more realistic option than people expect--
partly because modern flash-disks (with onboard controllers performing
wear-levelling) are *way* more resilient than people expect, and partly
because the way that swap ends up being used is vastly different from
what people expect--most notably, if there are parts of a program's
in-memory image that are rarely (or never) used, then those parts
can get swapped-out (once) to make room in RAM for disk-buffer/-cache,
and then may never be touched again.

Of course, it all depends on the program--if Xorg and whatever client
applications you want to run actually, *actively* use all of the memory
that they allocate all the time, then maybe `swap to flash' (or even
`swap' at all) isn't such a great option. One interesting thing to note,
though, is that `active' doesn't just mean `the program is running';
even if something is running, if you're not interacting with it,
and it's not doing something of its own accord, then there's a good
chance that the entire process can safely be swapped out and then
not touched until you switch back to it.

It looks like a fresh instance of Xorg occupies ~14 MB of RAM
on my laptop. Hmm

   RAM may or may not be a problem.  It's got 32 MB, which is more
than anything Project Athena had at first, but software seems to take
up more and more memory as times goes on.  Maybe swapping to flash?

We've had this strange routing problem several times over the last year. 
It makes no sense to me either, but power cycling the Comcast-provided 
SMSC cable modem/router has solved the problem in all four cases at 
three different clients. In one instance, the traceroute made it to the 
very last hop before their web server, and then died. I wondered if it 
could be some odd TTL issue. Comcast's tech support has been pleasant, 
but not very informative about the cause. Since power cycling works, and 
is quick, I haven't tried to diagnose it further though I'd like to know 
why it happens. In one of the other cases the route to a specific IP 
number immediately went along a completely different path than another 
IP that was in the same destination network. The other case appeared to 
start playing leap frog half way to the destination (hop E to hop F to 
hop E, etc.). The fourth occurrence I just had them power cycle. There 
may have been more cases, but I documented how to power cycle the cable 
modem for them (they are all small enough that it hasn't been a major 
issue) and haven't heard about recurrences.

  What leads you to believe this is a DNS problem?

  What happens when you try to access the site?  Do you get an error
message?  If so, what is the error message?

  Can you ping the website by name?  Can you ping the website by IP address?

  If you do a DNS lookup for the website name using "host" or "dig"
(or even "nslookup"), does it work?  Do this both using your default
DNS servers, and by explicitly specifying various DNS servers, e.g.:

dig ANY nnerenmls.com.
dig ANY nnerenmls.com. @68.87.71.226
dig ANY nnerenmls.com. @8.8.8.8
  What OS and version are you running?  Are you current with updates?

  What web browser and version are you using?  Have you tried clearing
your cache and cookies?  Have you tried a different web browser?  Have
you tried a  different computer?

  What model Comcast-provided equipment do you have?  Are you using a
router, or is the computer directly connected to a cable modem?  (Be
aware that some Comcast equipment combines a cable modem with a
router.)

   If you have your own router: Are you running the latest firmware?
What if you connect your computer directly to the cable modem?

  Etc., etc.

at least one interested article in it every month for the last

Thanks,

I think we're experiencing the same problem you describe.  I'm not actually
at the office that's affected, so I haven't done a traceroute or a dig at
the time when it's out.  I just know that the user's browser returns a "Site
not found" error as if DNS didn't work.  Granted, you'd get the same result
if routing didn't work, so I think it's actually a routing glitch.

I'll try getting some answer from Comcast, although I'm just plain fatigued
with dealing with them for any purpose. [1]

[1] Did you know that as a business class customer, you get three mutually
exclusive logins to access and manage your account.  One uses credentials
that are given to you at the time of account creation (was likely setup
years ago, so of course you've forgotten those).  That login gives the
ability to subscribe to and setup additional services that you don't give a
crap about - like a sharepoint service.  You'll need a separate login to
manage the VOIP aka "digital voice" service (but the 'portal' doesn't
include access to important aspects like managing your billing address).
 Any you'll need another login to manage your customer profile etc. -- your
real account.  And if you call technical support to change something like
your billing address, they will need to reset your account username and
password in order to make the change.  Their procedure is to set your
username AND password  to the phone number of your service.  I suspect that
it's trivial to gain illegitimate access to a large number of comcast
digital voice subscriber accounts.

I guess I should have prefixed that with make sure it's a DNS issue and not
a routing issue.  Because my prior experience with Comcast Business with the
symptom being one site being inaccessible makes me believe that it's a weird
routing issue.

This routing issue is apparently a pretty common issue with Comcast
Business.  The person who made the suggestion to reboot the router was tech
support at SaaS provider that we were having a problem accessing.
 Apparently they have had a few customers with strange routing issues with
Comcast Business where rebooting the Comcast router resolved it.

You can test for this issue by doing a traceroute before and after rebooting
the router and comparing the output.  I think you'll find out that the DNS
resolution is the same before and after you reboot.  At least if it's the
same issue that I've run across with Comcast Business.

So, you are telling us that the site becomes "inaccessible" in the
sense that it seems to fall out of the DNS?

> Any ideas on what could cause this and how to troubleshoot?

When you know you are experiencing this problem, it might be useful to
run these commands and provide us with the output:

  dig @68.87.71.226 nnerenmls.com A nnerenmls.com SOA 
  dig @8.8.8.8 nnerenmls.com A nnerenmls.com SOA 

If might be good to save the output of these too at a point in time
when you know that everything seems to be working too.

We have that problem here time to time.  It doesn't appear to be a DNS issue
in our case it's always been a very strange routing problem that happens
after a bunch of correct hops.

We are lucky enough to have a 2nd internet connection and when we have this
problem here I can traceroute from each connection and the comcast one
normally will get to the correct datacenter and then take a different hop
from our T1.  I've never been able to make any sense out of it.  But for
this reason I have a few sites setup to route out our T1 so that it doesn't
cause any interruptions in our business.

Rebooting the comcast router in our case has always resolved this routing
problem.  I'd be interested in any theories as to what causes the routing to
go awry after many hops and outside of comcast's network.

Those /are/ Comcast DNS servers in their "opt-out" configuration which means
that those are the servers that do regular DNS.   The other list is for
Comcast's "Domain Helper" service which is their "service" to answer your
typos with ads.

cable modem requires reboot because one site falls off DNS?

[Greg Rundlett (freephile)]

I have a strange problem where one (and only one as far as we know)
particular website becomes inaccessible to our office.

The "fix" for this problem is to reboot the Comcast cable modem, however I
don't understand how the modem could be the culprit.

The website in question is nnerenmls.com  and the modem is configured to use
Comcast's DNS servers
68.87.71.226
68.87.73.242

One red herring:  It would seem that Comcast changed their DNS servers,
because the ones currenty in the modem configuration do not appear in the
list http://dns.comcast.net/dns-ip-addresses.php  I thought to myself, "I
just switch to Google's Public DNS servers" (8.8.8.8 and 8.8.4.4)  I'm
pretty sure they are not going to change.  However, it doesn't make sense to
me that one website would fail, while general DNS would still be working.
 And, at the time of the failures, other people using Comcast can resolve
that domain meaning it doesn't even appear to be an issue where the target
domain is occasionally falling off the web.

Any ideas on what could cause this and how to troubleshoot?
