#167004 — TCP/IP over Bluetooth

According to https://en.wikipedia.org/wiki/Bluetooth ,
Bluetooth was "... originally conceived as a wireless alternative 
to RS-232 data cables."  Therefore TCP/IP inside PPP on a 
Bluetooth connection is hypthetically possible.

Has anyone tried it with a debian system on one end at least?

Thanks,           ... Peter E.

Google it? It appears to work fine now days - maybe issues with
NetworkManager though - idk. But no I haven't setup PAN, just 1 minute
(literally) with Google tells me this.

Unforch for many, its also a link you have to subscribe to, possibly with 
an accompanying fee to pay to access it. I value what little privacy I 
have left.  I'm also on SS and need to watch my cash flow.

I was blocked, 5 times so far, at the front page of the current issue.  I 
could poke around in the 4 sale areas, but could not access any other 
content, such as that sublink without signing up.

I was taken to the regular old front page too (probably because shawn's
m-dot URL is optimized for smartphones and they sense I ain't no
smartphone), but once at the front page I tacked on the '/article/10915'
part and away I went.

In other words,

http://www.linuxjournal.com/article/10915

works fine here.

Other front page links (I tried two) work fine for me also.

I finally did get to the article, but had to clear it with privacy badger 
and ghostery and no-script was already disabled. I have no clue what 
their cookies send back, but I printed it so I don't have to go thru 
that folderol again.  The sign up overlay never did fully render. But it 
had a close button that worked.

At one point, Privacy Badger was reporting 9 trackers, and Ghostery was 
blocking 24 data suckers. Noscript wasn't blocking anything as its been 
disabled for weeks.

The data these sites collect and sell, gets me 100 new spams every day. 
20 or 30 of for erectile disfunction cures that don't work.  I'm 81, and 
been diabetic for 25 + years, I couldn't reset my since counter if it 
was offered.  I don't have a place to put a hot tub, and my garage floor 
is bare cement & gonna stay that way. I don't need a DUI attorney, or 
the next great diabetes cure. Give me a break.

I keep being offered pills to increase the size/functionality of a part of my 
anatomy that doesn't exist.  My spam checker infallibly removes the offers.

The odd thing is that my husband, being in full possession of the relevant 
part of his anatomy, doesn't get any.

I get lots of "young ladies" soliciting for my affections too.

The spam writers obviously know something about me that I don't know about 
myself.

Bin them, Gene.  And save yourself the folderol.

Spamassassin, after several years of being fed all of that stuff via a 
daily sa-learn -spam command on that resting directory, still only 
catches 10% of it.

Gee.  I could let my imagination run wild and still not come up with a 
valid answer.  The image you project is that of an experienced lady, 
with poor eyesight you have worked around quite well, and generally a 
pleasant person to be around, and thats worth more than an 11 at closing 
time. :)

Interesting.  For me it catches 90%.  Do you feed it both spam and ham?

I feed it ham by moving stuff it should catch to the ham directory so its 
treated as ham on the next runs of sa-learn.  I could add a weekly 
sa-learn --ham session, nameing one or more of the cleaner folders from 
the mailing lists I suppose.  It was initially run over my cleaned up 
coco folder, which is several gigabytes of quite clean ham.  The initial 
run was many years ago.  Or, I suppose, I could use an int rnd(number of 
good folders) and the a stack of ifelses to do a name substitution based 
on the number and have it read them all at random intervals.

I should restrict the number of folders to those that I do have expiry 
times set on though.  Not all folders have expiry setup.  Those that I 
have primary interests in are here until I have an HD crash and no 
backups.  Since I run amanda every night, using a second HD as virtual 
tapes, that chance ranges from slim to point triple ought zip.  I may 
have the last blackout first at my age. :(

ATM I'm making parts for my mill on my lathe for another project that 
will triple the speed of the z axis on my mill, but there may be a down 
time before those replacement motor and driver parts all arrive in the 
next 2 weeks or so when I can slice up some bash code to do that.

Thanks for making me think of that and the fact that over the last 10 
years, the only ham its seen are its mistakes. So this question might 
have had the seeds of something to help. :)

AFAIK, the best of training a Bayesian filter is to feed it contents that is
typical of what it has to classify, and in particular spam and ham in the
same ratio as what you receive. Also, beware if there are some kind of mails
that you want to receive but never archive (for example notifications),
since you may never teach the filter to recognize them as ham.

OTOH, feeding enough ham is necessary to avoid false-positives. This
sub-thread was about false-negatives, IIRC.

My scripts copy all new non-spam to a ham directory which is fed to
sa-learn every night and then the contents of both the ham and the
spam directories are deleted.

Humm, I don't delete the ham, but drag & drop it to whatever folder it 
goes to after its spent a day or so in the ham directory. I move the 
detected spam to a spam-hold directory in case I neglect to check for a 
day as its catching the order confirmations from ebay because ebay just 
has to use 99% of the confirmation message to sell more usually 
unrelated crap, and that spam-hold is deleted on the next sa-learn run.  
But thats a good idea for genuine ham, but so much crap gets thru I'd 
still have to go thru it and clean it up before sa-learn saw it.
Its a thankless task for sure.

I have Mailagent delete all high-scoring spam so that I never see it
all.  Low-scoring spam is sorted to my spam folder by Gnus.  When
Spamassassin is working well there are only half a dozen of those a day
so it's easy to review them all and put them where they belong if they
aren't spam.  I see maybe one or two untagged spams a day: I move those
to the spam folder where sa-learn will see them.

Mailagent also has a whitelist and a blacklist.

IIRC, it seems pointless feeding your mail through a spam filter
if you're downloading it from your ISP/email provider.

I think you are assuming the ISP provides a spam filtering service and
you are happy to entrust the deletion of your mail to it.

There is still some truth to the above:

The most effective measure against spam these days is rejecting
the mail up front (i.e. while the SMTP session is active). This
way a (hopefully rare!) false positive is rejected in a way the
sender can act on it.

Once you got the mail it's too late. Either you have to generate
a bounce (not a good idea these days, because real spam will have
bogus headers and the bounce will hit a poor unsuspecting victim),
or you have to look into the spam anyway, or the spam disappears
in a black hole (again not a good idea, since in the false
positive case the sender will newer know).

Therefore once your ISP has accepted the mail for you it's kinda
"too late" -- they better have a good spam filtering setup in
which you have some influence (the spam filter will only work
if it has a notion of what *you* consider to be spam/ham).

#167140 — Re: Is running spamassin on a home server a waste? (was ... Re: TCP/IP over Bluetooth)

Hi list,

I am running spamassassin in kmail. As I got several spam from my provider 
although there is a spamfilter active, I trained my own spamfilter very well.

There are no false positives or negatives since many years. 

However, some spammails still appear (about 2-3 a week), but this is no 
problem and I use them to train my spamfilter better and better.

All Spam will be moved into the wastepaperfolder (or whatever that thing is 
called).

Of course, a spamfilter is best set at the receiving mailserver, but I made the 
experience, that all spamfilters from the mailproviders are low quality. I 
suppose, these are all commercial products, and we all know, what quality 
commercial products have, do we?

Hope this helps a little bit.

Best regards

Hans
