LOL dude! :)  If u think I was calling anyone a thief u read something that
I didn't type.  The idea of what is thievery or allowed use rests solely in
the mind of his customers.  In this arena whatever *they* say goes.  Forgive
me if I used overly colloquial meanings of steal and thief. :)

Well, that's exactly the attitude I'm objecting to! Sure, they have as
much right to try and stop me doing things they don't want as I have
the right to actually do them, but that doesn't make these things
'thievery' or 'illegal'.

Whether something is 'stealing' depends on *law*, and is not determined
by his customers or any other publisher. Unless of course the publishers
determine the law, which is indeed what seems to be happening in some
places of the world.

> In this arena whatever *they* say goes.

Not when we're talking about what's criminal and what's not.

Cheers,


Emile.

Yes, that's true, but is irrelevant for his situation.  His web hosts are
coming to him saying "we want X".  Whatever X is, whether that's streaming
video people can't copy, etc, he has to provide that or they walk.  That's
why discussions of rightness or wrongness in these situations is moot.

Sure. That's also why I said that they have as much right to try and

Re: upgrading just one "stable" package to "testing" version

2002-03-19 Thread Jason Lim

Your sources.list must not be correct then, or something is fubared
somewhere.

Try this...

rm -rf /var/lib/apt/lists/*

then make SURE /etc/apt/sources.list is correct.

Then update the package list, and try and get dpkg first, then apt.

That should work. Let us all know the result.

Problems tirying to setup a pptp server begin a firewall

2002-03-19 Thread Raúl Alexis Betancort Santana

 Hi all, I'm triying to do the next setup ...


 Inet <-> Sid FW (Pc1,eth1-inet,eth0-lan) <-> Sid PPTPd (Pc2,eth0-lan)

 On the PC1 I have done this

 iptables -t nat -A PREROUTING -p gre -j DNAT --to 192.168.0.2  
 iptables -t nat -A PREROUTING -p tcp --dport 1723 -j DNAT --to
192.168.0.2 

 Along other rules that don't get into colission with this ones 

 When I try to make a conx from a WinXX machine with the VPN support
(pptp), It connect (I saw the pptpd launching the pppd on the PC2), 
and there is GRE traffic (tcpdump -i eth0 proto gre; on pc2 show
that), but the WinXX machine allway stay saing "Checking username and   
password" till it get a timeout.

 Appart from a possible problem with the pptpd/pppd config, are this
rules OK to *forward* such kind of traffic from the FW to the internal  
server ?

 Thx in advance

Have you checked whether GRE traffic in the other direction is allowed
as well by PC1?

Also, what is pppd doing with the incoming traffic? Turn pppd debugging
on and see if it actually receives the PPP LCP packets from the client.

Emile.

Best to write a short note yourself if the message has some special

 That's strange. Stable has apt 0.3.19; testing has apt 0.5.4. This

If you just want single Packages from other versions of the distribution,

Well, true. I never said it was the best way... as you said, RAID is the

Mmm... but then, what if you ARE speaking for your company, but don't want
that person to then send it off to their internal mailing list or
something like that?

Tough luck.

If a representative of vendor for a project I'm working on sends me an email 
then I will forward it to my colleagues if it is appropriate.  When at a 
meeting with a vendor I'll read their notes (I'm reasonably good at reading 
upside down).

Some of my friends even take hidden tape recorders into meetings.

These things only become an issue when you have a rival consulting company on 
site and they get a copy of the info.  But the usual laws and contracts about 
non-disclosure are good enough to deal with such situations.  A sig line 
really won't help.

Unfortunately that is one skill I have not yet perfected ;-)

> Some of my friends even take hidden tape recorders into meetings.

I thought that, legally, one would have to actually warn the person being
recorded that a recording was taking place. I know that when I phone a
number of large companies, they say specifically "this call is being
monitored for quality assurance purposes" or "for training purposes" or
something. I don't think it is legal for them to secretly record messages.
But again, if it isn't done for malicious purposes... well... hum... its
still debatable ;-)

But laws regarding email are still pretty shady at the moment... i
would've thought a short statement like "This message is private and
confidential" would at least help to clarify and make obvious the fact
that you don't want people giving this information out to third parties
(make that competitors and such), and allow a company to "more easily"
enact any applicable non-disclosure laws.

We certainly wouldn't want a client to sending the details of our private
deal with them to a competitor or other clients. Imagine what would happen
then! "Hey, you gave him 2U more space than us for the same price!" hehe

The use of a hidden recorder can only be considered as "malicious", unless 
you are the one with the recorder.

If it's added manually yes.  If it's automatically appended to everything 
then it can be safely ignored.

Well you need to have a specific clause in the contract if you want that to 
happen.  But no-one sues their customers so as long as your customer pays 
their bills then you can't do anything about it.

Best thing to do is tell them that you're giving them an extra good deal and 
that if they tell anyone then they get the "standard rate" next time.  Tell 
that to every customer including the ones who pay more.  ;)

No, Qpopper or something else would cause minor glitches in the "^From: 
" header or the line before it would be missing (2 messages joined at 
the hip).  If Qpopper would see an "un-escaped" From: header it would freak 
out and die.  I was the only person reading mail locally on these 
servers... I used vi to fix these broken mbox files.  I would touch the 
lock file manualy, vi the mbox file in question and then delete the lock file.

I hope exim works for you, everybody should use the best tool that they 
prefer to use.  One of these days, I will try to make an exim mail server 
but I have too many qmail servers running without requiring attention, it's 
more trouble to switch now.

Colorado Tape Backup Problems

2002-03-19 Thread Daniel J. Rychlik








Hello,

 

I have an old Colorado Tap backup – floppy controller –
that I've been trying to get working for sometime now.  I have searched on the net for possible
solutions but have been unsuccessful in finding information.  I have installed debian’s ftape
software and played with, but alas, I am unsuccessful.  

 

Does anyone have suggestions on this matter?  I appreciate any ideas or
suggestions.  

 

Sincerely,

 

Daniel J. Rychlik

RAID 0 risky ?

2002-03-19 Thread Thedore Knab

Is RAID 0 that risky anymore for data storage (IMAP mail files) ?

I figure that under normal wear and tear a drive should last about 5 years.

Does this sound right ?

I have 3 IBM SCSI 18GB drives. 

With RAID 0, I get 51.5GB of storage space. 
With RAID 5, I only get 37 GB of space with 20% wasted overhead. 

RAID 0 and RAID 1 are less work for the disk volume than RAID 5.

So in an ideal world, volumes with RAID 0 or RAID 1 will last longer than 
volumes in RAID 5.

Thus, it would be less risk to use RAID 0 or better RAID 1 than RAID 5.

Re: RAID 0 risky ?

2002-03-19 Thread Dave Watkins

Technically speaking drives don't _wear_ out... Bad sectors are generated 
because at some time the disk surface has been damaged, usually by the 
heads hitting the disk. And many faults to do with the components on the 
controller board can be traced to a poor supply of power (eg spikes and 
brownouts, a UPS will help resolve this)

Other than that, RAID 0 is more risky than a single drive as you have no 
fault tolerance (one drive fails and you lose all the data on al the 
drives), and you have three times the chance that one of the drives will 
bomb for whatever reason. Since it is for mail storage (an inherantly 
difficult data source to back up), I would say using RAID 0 would be a VERY 
bad idea, especially since you mention IMAP (eg mail stored on the server). 
If one drive fails every user you have loses their mail.

I would think RAID 5 would be the better system to use in this instance.

To follow you usage question a little. Lets assume you want to write 256k 
to the array.

(We assume 64k block size for all arrays)

In a RAID 0 situation the first drive would have 128k written and the other 
2 would have 64k written to them.

In RAID 1 (using 2 drives) each drive would have 256k written to them.

In RAID 5, each drive would have 128k written. There would be 2 x 64k 
written to the 2 data drives, as well as another 128 on the parity drive 
(for this particular write).

This is simplified but correct, from here we can see that RAID 1 would have 
the highest usage patterns per drive, next would be RAID5 and finally RAID 
0. This is of course the price you pay for redundancy, you have to 
replicate the data somehow. RAID 5 obviously does the least replication 
while still keeping fault tolerance, although it does cost a small amount 
of computing power (not a problem if you have a RAID card)

Hope this helps
Dave

No. In RAID 5, you can lose one drive, and still keep running. In RAID 0
(striped), the loss of one drive will kill your volume. Let's say the
odds are 1 in 10 of a drive dying in a particular year. If you have 5
drives in RAID 0, you have a 50% chance of your volume crashing (well,
that's probably not exactly right, but my statistics abilities are a
little rusty). If you have 5 drives in RAID 5, you have a 50% chance of
_one_ drive dying.

I'm not sure that there's significantly less work for RAID 0 than RAID
5. RAID 1 will definately have less reads on any particular drive than
the other two (approzimately 50% will go to one disk, 50% to the other),
but will have greater writes (100% of writes will affect both disks on
RAID 1, it's possible some writes will not affect every disk on RAID 5,
I think).

Since you're looking at IMAP mail files, the data is probably
critical... too critical to trust in a single drive failure. You're
probably most concerned with read performance (since users will notice
lag in reading email... deleting messages can plod away just fine,
writing to the mail files is done by the MDA). Take a look at how much
space you need, or are likely to need in the future. If you need a lot
of space I'd go with RAID 5. If you want to really push the read
performance, buy another drive and go RAID 1.

I'd stay away from RAID 0 unless it's fairly non-critical data, and if
you really need the throughput. An example I can think of would be
something like a web cache.

> 
> Thus, it would be less risk to use RAID 0 or better RAID 1 than RAID 5.

Absolutely not. RAID 0 is the highest risk. RAID 0 is actually higher
risk than a single drive.
