"Word of Mouth" - spam? (OT)
Hi all, I'm sorry about the off topic posting. Every so often I get an onsolicited mail announcing that someone posted a report about me, or that someone is looking for information, on a site called "Word of Mouth". The site is at http://www.wordofmouthconnection.com. The site baldly claims that "this is not spam", and that the email was triggered to inform me that someone is searching for information, or is offering information, about me. Now here's the catch - the searches in that site are performed according to email address. There is someone that claims to "know me well", using an address that I have only used once, for a specific purpose, and never with friends! What's more interesting is that every so often someone actually performs a search on that site for that very same (only rarely used) address! Not even spammers bother with this address any more. Google doesn't show any results when searching for it. Now I'm at a loss. Either someone is attempting a very strange sort of slander (why would someone look for me under that email?), or this is such a soficticated sort of spam, that I have not managed to figure out what it is (maybe they are selling commercials at the site for the confused people who want to walk in and find out what the !%&([EMAIL PROTECTED]&!() the email is about). Any ideas would be greatly appretiated.

Thank you all...
In the recent few days, I asked many questions on this list. I would like to thank this list for all the help. It really shows what a community we have here. This is what I like the most about Linux (aside from the chalange of learning new things everyday...). All answers where very helpfull something that we do not see everyday on the net. Now not only that all recent problems are solved, things that did not work before but I did not bother to fix are now working perfectly. SO THANK YOU ALL AGAIN. -- Ori Idan (This mail was sent using Kmail running on Mandrake GNU/Linux) = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

already have RAID1 on both servers so I would just like to keep the
arrays identical.
As far as I understood it, the meaning of "NAS" is that you'll have
common storage accessed over the network ("NAS" = "Network Attached
Storage"). What does this have to do with each server having its own
RAID?
BTW, If you already have RAID 1 (mirroring) and if you have more than
one disk on each mirror side (i.e. at least 4 disks total in each
mirror) then you better do RAID 0+1 (mirroring over stripping), to
enhance your access times.
(e.g. http://www.acnc.com/04_01_0p1.html)
Right now we will stick to having both servers at the same location, my
question was about changing the IP address dynamically if something
happens if we ever decide to setup a backup server on another location.
You had two questions, haven't you?
As for this IP question:
1. If you want the backup server to serve also at "regular times"
then just advertise both addresses in A records in DNS, the DNS
server will alternate their order when resolving the server's address
which will be a very cheap way to load-balance between them.
2. If you just want the bakcup server to be accessed only when the
primary one goes down then the only way I can think off right now is
with having setting the A record with a very short time to live (5-15)
minutes, as much as you can stand with having an inaccessible server)
so your DNS will be accessed almost every time the site is accessed,
when the primary goes down (which can be discovered with various High
Availability solutions) the secondary updates your DNS server and takes
over control.
See http://linux-ha.org/ for instance.
(1) and (2) can be implemented together (advertise both, when one
server goes down the other will delete its address from DNS, when the
downed server goes back up it will register with the DNS).
There are also mailing lists, forums and sites about Linux high
availability, maybe you'll find there more knowledgeable crowde, though
I for one would be curious to hear what you decided to do.
My suggestion for a general direction to investigate:
1. Check rsync more closely - as far as I remember from using it, it
is actually a very efficient program in CPU, memory, and network
usage.
Yes, but I'm not sure that running it every 10 minutes is a good idea,
especially if you have many files and some of them are being changed
while rsync is running.
Have you conducted your own tests or found results of such tests?
In general, rsync is supposed to cope well with changing files.
I found out about a kernel module named "enbd" which is supposed to do
RAID over network somehow, but I would like to hear about the experience
of others before I start to play with it.
Never heard of it, though I did see the "Network Block Device" option
in the Kernel 2.4 config, which sounds related to this. I'd expect you
can google for a community of this module.
2. What about using a content-management (CM) solution which manages
your site instead of handling files "manualy"? Keeping track of your
files through a CM software will enable it to copy over every file
when it's updated, and it can also sort-of track changes and versions.
I can't recall a particular software for this, maybe you can start
by looking for WebDAV implementations (e.g. Apache's WebDAV module).
I'm not sure. Basically we're storing all the data in our database and
only use the filesystem for files - image files, flash files, website
root directories etc.
That's what content management is about.
All the files must be accessible by apache (it is serving the images
directly, we don't read them in our application) .
What I was suggesting (never tried this myself) is that instead of just
writing files directly to the disk and hope that some sync program will
find it and copy it over, use a tool which writes it to the disk (so
it's accessible by Apache) but in the same time can send it (or notify
about the change) to the backup server. WebDAV is one standard protocol
to achive the "write a file to a Web server" part.
Also when you have such tools instead of directly writing files to disk,
you can start using other tools on top of them (QA, testting,
versioning, authentication, authorization, general site management)

I don't understand why you think the situation is any different from other "Add 3 inches" or "Help me transfer $10M" spams. The site you mentioned wants people to come to them, so they spam you and stick a line saying that "this is not spam"... So the most likely and straightforward explanation is that the owners of this site themselves created the spamming list and are pretending that "this is not spam". The very unlikely explanation is that someone else is (ab)using that site by entering other people's email addresses that that person somehow got hold of (e.g., from a spammer's list). Even if this is indeed the situation, the fact that that site sends out their emails to these addresses simply means that they found a way to knowingly spam you with "plausible deniability": they can claim that they aren't spamming - someone else entered your email... That is similar to anti-virus software spams: Anti-virus software writers know that certain worms fake "From:" addresses, but they still bounce copies of these worms. Why? Because it lets them advertise their product to millions of random people on the net, without it being labled spam, and without them having to pay a cent for the transmission of these ads. Well, do you know what? I still call those anti-virus "you have a virus!" ads spam. At some points in recent history, I was getting more of those spams than "normal" spams. -- Nadav Har'El| Thursday, Sep 25 2003, 28 Elul 5763 [EMAIL PROTECTED] |- Phone: +972-53-790466, ICQ 13349191 |He who has more is not happier than he http://nadav.harel.org.il |who wants less. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Israeli NTP server with support for Day Light Savings
Hi, Lately I heard rumors of the idea of changing the Day Light Savings from +-1 hour to +-2 hours, and changing it on less of a regular basis that it is now (I didn't notice it was on a regular basis ... It always appeared to be changing at random). Anyhow my question is whether there is an Israeli NTP server that keeps track of these things, allowing my organization, and others out there to keep track of these time changes.

It's dead easy: 1) apt-get install mailfilter - it only depends on libc, libstdc++ and debconf, so no baddies there. :-) 2) modify ~/.fetchmailrc with the 'preconnect "mailfilter"' line, which goes in a slightly non-obvious place, as in my example (attached); only one 'preconnect' line is needed to check multiple mailboxes, as mailfilter gets the info on which boxes to check from its own .rc, not from fetchmail. 3) modify my attached ~/.mailfilterrc with your POP3 username and password details. The DENY rules to filter out viral crap are translated from posts by Greg Lehey and David Lloyd on the LinuxSA list. The ALLOW lines are to cope with the possibility of list traffic arriving with large log files attached which would otherwise be knocked out by the MAXSIZE limit. You must have the log file. You can add a line 'TEST=yes' to run in 'dummy' mode without actually deleting everything. The DENY and ALLOW lines must not contain line breaks. The one thing mailfilter does seem to lack is an option to filter based on the output of some external program, so you could link it with some Bayesian engine to avoid manually tweaking the rules. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F # Configuration created Fri Nov 29 01:13:30 2002 by fetchmailconf set postmaster "postmaster" poll pop3.ukonline.co.uk with proto POP3 user "jah.pigeon" there with password "something" is [EMAIL PROTECTED] here preconnect "mailfilter" poll pop3.ukonline.co.uk with proto POP3 user "my.other.user" there with password "somethingelse" is [EMAIL PROTECTED] here LOGFILE=/home/pigeon/mailfilter.log SHOW_HEADERS=yes SERVER=pop3.ukonline.co.uk USER=jah.pigeon PASS=something PROTOCOL=pop3 PORT=110 SERVER=pop3.ukonline.co.uk USER=my.other.user PASS=somethingelse PROTOCOL=pop3 PORT=110 REG_CASE=yes REG_TYPE=extended MAXSIZE_DENY=5 NORMAL=yes DENY=^Content-(Type|Disposition):.*(file)?name=.*\.(asd|bat|chm|cmd|com|dll|exe|hlp|hta|js|jse|lnk|ocx|pif|scr|shb|shm|shs|vb|vbe|vbs|vbx|vxd|wav|wsf|wsh) DENY=^(Subject|SUBJECT):.*(Latest Net Critical Update|Bug Message|Abort Letter|abort notice|Failure Message) DENY=^(From|FROM):.*(Microsoft|MS Email Delivery System|Inet Email|Internet Message|Inet Mail Service|MS Internet|Net Delivery Service|MS Mail System|internet email delivery|MS Network Delivery|ms network system|MS Security Services|Inet Mail Storage System) ALLOW=^From:[EMAIL PROTECTED] ALLOW=^From:[EMAIL PROTECTED] - End forwarded message - -- Shaul Karl,shaulk @ actcom . net . il = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Dear Noam, NTP servers are clueless about timezone. They only tell the time in UTC. It is your local Operating System that knows about timezone, and adjusts the time by it. As such, no NTP server will ever know when the local time was moved to daylight savings time and back. NTP servers are universal, and anyone can sync with any NTP server, be it here or in Timbaktu.

Assuming one server is always active, and the other one is passive, we map the

storage at a given time).
when a failover happens, the passive server "steals" the ip of the active
server, and it's storage as well and mounts it.
after this, the application is being executed and all should be fine.
what's not too good is that sessions are lost, so if youre application is

Re: live website mirroring
As far as I know, the cost of SAN is very high. It also gives your more GB
then you need. And if you need less GB than what given - you just pay too
much extra on each GB.
Also, don't forget the equipment using to work with fiber optic cables
(control cards, switches and so on).
At this cost I think you can build a HA solution:
1. A red rubin DNS.
2. heart bit.
3. using another computer for db/files and two servers to serve the files
(sure, has lower performance).

With NAS, you introduce a third computer, that serves the files to both servers (single point of failure), you need some way to ballance the load (round robin DNS, in your case, which suffers serious problems when trying to cope with a failure). I'm not even sure that the fiber option is so expensive (quite honestly, I don't know).

Basically, you are saying that people have absolutely no problem > sending e-mails that appear to come from me. I find it quite amazing. Welcome to the world of SMTP (the "Simple Mail Transfer Protocol", the standard protocol used to send mail on the Internet). Circa 1992 I used to amaze my friends (those who studied in the Technion and had email addresses, that is) by sending them email "from" [EMAIL PROTECTED] Nothing has changed since... PGP (or the freeer GPG) is a good solution for mail authentication (and privacy) that lets you "sign" your email in an unfakeable fashing, and yet does not require central authentication [1]. It is not trivial to understand PGP's concepts, but if you are willing to spend a few hours learning them you might actually like it. And best of all, GPG is free software. Just watch out: do you really want each and every one of your emails to be 100% traceable to you? After sending fakable email for so many years, I got used to it, and I actually started to get scared that people could prove that I sent a certain email. Sometimes I write stupid things on this list - why would I want not to be able to deny that I wrote them? :) This is why I never sign my outgoing email, even though I'm perfectly capable technically to do so. I do sign other things that I deem important enough - like free software packages I publish. I think we had this discussion on this list a while ago, so I won't continue further. and now for the Educational Footnote of the week ;) [1] An example of central authentication is government-issued ID cards or driver licenses. Another example are credit-cards issued by certain large (and supposedly trustworthy) companies. Yet another example (on the Internet) are SSL certificates issued by certain companies called "certificate authorities" (CAs). The problem with all those centralized schemes is that they require a central entity to authorize you - this usually requires significant fees, and a significant amount of effort and red-tape to set up. Decentralized systems like PGP, on the other hand, let anyone invent their own unique identity (or several such identities). How does that help in authentication you might ask? Well, the "trick" is that nobody trusts just any random identity shown to them - you only recognize the identities sent to you by friends you know from real-life and you previously got their PGP identities from secure channels (like face-to-face meetings). Also, if your friends recognize other people, you can recognize (to a slightly less degree of confidence) your friends' friends', and so on. This is called a Web of Trust. For example, I recognize Muli's key because he showed it to me when we were in last year's August Penguin event. Muli might have signed with his key a statement that he knows Linus Torvalds' key because he (may have) met Linus in a conference last month. Now, if Linus Torvalds sends me a signed email, I can recognize his signature to be genuine (with a certain degree of confidence) - even though I never met him before, and no central authority has decreed this signature to be authentic. All the operations I mentioned above are made secure and unfakable by using public-key cryptography (it's a very interesting mathematical subject, really, you'll like it ;)). -- Nadav Har'El|Friday, Sep 26 2003, 29 Elul 5763 [EMAIL PROTECTED] |- Phone: +972-53-790466, ICQ 13349191 |I had a lovely evening.

There's no Java or Flash used on this site, just cleverly-made cross-browser DHTML (JavaScript). Really a piece of fine work! Works on Mozilla 1.4. Java was not loaded.

To be even more precise - *LOCAL* timezone is irrelevant, but NTP must keep the time in SOME timezone so you can relate to it when translating to a convenient timezone by date(1) and friends. That is what UTC (a universal timezone, which happens to be similar (not identical) to GMT) is about. It's not Debian, actually (just because it makes more sense to maintain it in one place for all OSes). http://www.twinsun.com/tz/tz-link.htm But do other distributions keep the Israeli timezone up-to-date out of the box? I didn't know about the link above and didn't have to go to Ephraim's TZ page at HUJI CS (the real authority for Israeli UNIX timezone files) since I installed Debian except in order to tell Linux users of other distributions how to keep up with the Israeli TZ, it's just a question that never comes up when you use Debian unstable. --Amos = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
