ORBZ was too aggressive

ORBZ Shuts Down
·
· Score: 3, Interesting
As an active anti-spammer, I found ORBZ was too
agressive in filtering spam. A spam filter is no good if it results in too many false positives. I had to stop using it. I don't know the specifics of this situation though and it could just as well be over-agressive lawyers.
Here's the filters I use. Note that RBL requires permission, but is freely given and free for individual users (organizations/companies must pay).

I rather spend a few extra seconds loading up large executibles than have yet more DLLs preloaded.
You see, with Microsoft Windows the more DLLs there are the more DLLs there are to break. Windows DLLs don't have versioning (unlike UNIX or Linux). There's only one copy of the DLL. So when you install another, newer app, Office can break.
Of course not. However, it means there are several people floating around in China that are technically able or know English or both.
To say nobody knows english or noone knows how to configure computers (even something as simple as closing an open relay or replying to email) is avoiding responsibility.
"[In the] People's Daily, Xu Detian called upon the National People's Congress to pass a law banning the sending of junk e-mail."
This reminds me of my days in grad school in the early 1980s. I had two Chinese roommates. They subscribed to People's Daily to learn English (even though it had spelling and grammar errors, it was probably a good idea).
Anyway, after a while the paper began to sound repeative. It would continaully brag about some "new effort" to do something such as "end corruption" or "end pollution" or "improve education." That was done by passing laws saying "don't do this" or issuing a directive to "do that." Nothing would actually hapen, it appears, as I would read about a very similar effort a few months later.
So, although the Chinese are beginning to realize they need to do something about spam, don't hold your breath. Hopefully, they will come around some year to doing something effective . . . such as having ISPs actually respond to abuse reports and close open relays, for example.
That's funny. Besides China/HK/Taiwan/Korea/Japan, I get a lot of spam from EU. Especially Denmark and Spain.
However, at least some of the EU and USA ISPs respond to spam complaints. None of the Asian countries above have responded to spam complaints. It's not just a language problem either. I get (or used to get before my spam filters went up) technical requests (in English) from Asia as the result of USENET postings and FAQs I wrote.
I'm hopeful that one or more of the Asian countries above will clean up my act and I can remove my spam filters.
Don't block yahoo.com down.
If it's really from yahoo.com, email abuse@yahoo.com with the full email (including headers) and the original subject. They actively shutdown spammers, including the Nigerian "419" fradulent spam.
Well if you measure Internet usage by the amount of spam that is sent (at least received by me), it's certainly true right now that China, Hong Kong, Japan, and South Korea are "hot spots" right now in the Internet.
Hopefully, they will mature in the near future and be less abusive of the 'net. For now, I have to filter them out with sendmail to maintain my sanity:-).
I receive messages like this once or twice a month. The questions are very similar, which leads me to believe they copied the sample email or letter from some career guidance book (e.g.,
What Color is Your Parachute or similar).
What I'd like to know is why they are doing it and what book the canned message is from.
OK--the domain's lost. It was suckey anway.
Since you still have kdhx.org, I suggest you
renew it for the maximum term--10 years.
It doesn't cost that much 10 times $35 or so.
Representatives only want to hear from their constituents--those people in their district who they represent.
As for email, your representative may be a
"technofossil". My representative's email is secret. You can write or fax him, but no email.
Probably doesn't want to be overwhelmed.
I don't have millions to donate either.
Read the name, OK. XFree86. Note the *86*.
That means it's written for the Intel/AMD family
of microprocessors.
Porting to SPARC would be non-trivial.
BTW, more information is at my Solaris x86 FAQ

Sorry-you got it reversed. Blocking un-reversable addresses are the default in recent versions of sendmail. What you describe is how to DISABLE this feature. That is, how to accept unresolvable ip addresses (and how to get more spam)
Linux 2.4.5 and Freeswan 1.9 is broken.
If you want to use the Freeswan patch, either:
1. go back to linux 2.4.3 (2.4.4 has serious problems)
2. wait for an official freeswan update, http://www.freeswan.org/
3. Try the bleeding-edge snapshots from freeswan.
Sure it's OK. How do you think most of us pay the rent/mortage? We're not in some alternate universe:-). Open source stuff is what most of us do after our regular day jobs. Few are wealthy enough to work exclusively for no pay.
Bad example. Win 95 is definitely NOT a server OS.
You can run Apache or some other web server only in a test environment. Win 95 has some fundamental bugs with TCP socket handling. It doesn't close the server end properly. It omits ending the final ACK packet and the socket stays in limbo (some time wait state).
Win NT/2000, OTOH, handle this correctly and can serve web pages (and other stuff).
Bizarre Troll? Not at all. TPC-C is a synthetic benchmark that's almost 9 years old. It even predates the web (outside CERN at least)! It involves only 5 concurrent transactions. How many database applications behind a web server can survive with only 5 concurrent transactions now a days? Sun's Enterprise 10000 system has up to 64 processors. How can you gage that with a 5 || transaction benchmark?
I do admit that TPC-C is better than nothing. It's better than Towers of Hanoi or computing primes or timing straight disk I/O.
Sorry--it sounds impressive that Fujitsu's hardware won in some TPC-C benchmark, but I've always stood by the saying that there's 3 kinds of lies: "lies, damn lies, and benchmarks." What you need are some numbers from a large real-live application. Something that uses a large database, say Oracle, with several parallel transactions.
bind 8 doesn't have to run as root. If you start bind (named) with "named -u uid" it runs as the specified uid. This can be changed in your/etc/init.d startup file for automatic startup. Just make sure your bind cache files are readable and writable by bind:
$ ls -ld/usr/local/named
drwxr-xr-x 5 named named 4096 Jan 31 17:13/usr/local/named/
$ ps -ef |grep named

Sun Microsystems in San Diego has Internships.
Last summer we had a bunch. We're building more
offices so try next summer.

but it has some real information behind it).

We also have regular jobs too.

According to a news.com article, http://news.com.com/2100-1001-819578.html AOL buyout rumor is false.

I notice Slackware and Debian also have ksh93.
Solaris (and I believe HP-UX and AIX) have dtksh (part of CDE), which is ksh93-based with some GUI extensions. That can be used for a ksh93 platform.
For information on Korn shell, see http://www.kornshell.com/
With ksh, you can more easily interoperate with commercial UNIX systems, which now a days all come with ksh.

He probably won't listen to me anyway. I wrote a rather unflattering webpage about him at http://cunningham.carlsbad.ca.us/
Actually, many or most ./ers seem to be born after email was invented.
I used to call it "electronic mail" or "computer mail" or usually just "mail." Only in the mid- or late 1980s did I hear "e-mail."
