As far as I can remember you couldn't compile the drive statically in
the kernel - probably due to licensing issues.
I should be possible to put into the '/boot' directory on a floppy and
load it during the setup process (i.e. preload modules from floppy).

  The Controller used in the ProLiant ML330 series is an IDE-RAID and most
  of the logic is not done by the controller but by the driver itself.
  So performance will probably suck...
 
 My links refer to source to compile the drivers as a module.
 It's gpl released.

I just took a look at the files I got from LSI (who now own AMI) and the
driver is half GPL, half proprietary.

Quoting megaide-shimdriver-readme.txt:
LSI Logic's Shim driver has its raid intelligence as binary file
megaide_lib.o and the rest of the driver is open. megaide_lib.o can be
build with the open source to get driver image megaide.o.

Little BIG problem with Backbone

2004-04-09 Thread Michelle Konzack
Hello, 

because I am in paning of a CyberCenter Network in Marocco the idea is 
exploding !!! Exactly, I need very much Backbone-Power which can not 
provided from the Maroc Telecom

They offer me only E3 with 34 MBit !!!

And 34 MBit for 450.000 DH/month (41.000 Euro/month)

Only my Proxim Tsunami MP.11a (12 Access Points) support 216 MBit or 
effectiv 160 MBit and this only in one city !!!

Now there are some enterprises in Marocco which had ask me, why not 
installing a second Internet-Network !!! 

Oh yes, ist is no problem !!!
We need only a dual GigaBit Fiberoptic Sea-Cable from Espain to Marocco !

What a joke !

OK, crazy, but I have contacted CISCO for some routers ;-) and some 
other Manufacturs for Radio-Bridges (34 - 155 MBit and 1 GBit)

Now my Question:

Creating a Local GBit-Network in Marocco is generaly no Problem, it 
is not a big difference between it and my local network, exept I need 
a little bit more cable. 

BUT how does it work with the Connection to the Internet, exactly to 
the other Backbones ? 

Any Informations are Welcome...

Aren't there other providers? I remember many routes to Morocco using 
Seabone. You can find a contact at http://www.tisparkle.it/contacts.htm
And I know also Sprint has a PoP available in Morocco. There should be 
more. What about France Telecom, Telenor and Telefonica?

Of course you should plan your CyberCenter close to an important 
crossroads of telecom infrastructure since Maroc Telecom will probably 
charge a lot for leased lines with such high bandwidth while you 
actually need dark fiber.

in theory this is correct, but you should think about good manageable 
switches, so that you can build vlans. Without vlans your security in your 
network is not so good, because every computer can arpspoof and so sniff in 
the traffic of the other ips/nets you have conntected to the switch. Even 
Man-in-the-middle attacks are possible, if you don't think about vlans. You 
can also bind only fixed MAC Addresses to the switch ports, so that nobody 
can spoof another MAC/ARP of others, but I would prefer vlans :)

 BUT how does it work with the Connection to the Internet, exactly to
 the other Backbones ?

okay... in short: You need to contact the ripe and ask them for an AS Number 
and for an IP-Network for you.

If you got you own AS Number, you can configure your cisco router (or every 
other router which is able to use BGP (routing-protocol)) to annouce this AS 
to the next AS (which normaly is the AS of your uplink (Maroc Telecom for 
example). The AS of your uplink will annouce your AS to his next AS and so 
on, until every AS in the world nows how to reach your AS.

And you can announce over this AS Path your IPs (you got from the RIPE).

After you made this, you should be reachable from all over the world...

 Any Informations are Welcome...

I can only give you a short overview over the things you need... (bgp router, 
AS-Number, IP-Network). But you should inform yourself on other internet 
sites... just search for: bgp which stands for border gateway protocol or 
AS. Even the ripe site should be quite informative.  

In short: BGP is the protocol that makes the internet work, because all 
provider use this protocoll for their dynamic routing.

With bgp you can also use multiple uplinks, even with the same network. So 
that you can send and recieve pakets for you network over two uplinks for 
example. This can be used for redundancy and for combining multiple uplinks 
(if you need a lot of bandwidth)

|  BGP-4 Routing

|  * customer is responsible for maintaining his routing;
|  * customer needs to have his routing policy filed at RIPE.

Many things to learn...

And the the Office in Rabat/marocco:

mailto:[EMAIL PROTECTED]

IAM (Itisalat Al'Maghrib) is the Maroc Telecom and SeaBone has no 
own POP in Marocco. It is the Maroc Telecom. So this solution ist a 
little bit too expensive. 

And I know also Sprint has a PoP available in Morocco. There should be 
more. What about France Telecom, Telenor and Telefonica?

NO, all Provider are using the Network of the Maroc Telecom and because 
there is no second Provider they can make the Price how they want.

It is not good for Clients. 

See prices of ADSL:

http://abonne.menara.ma/adsl.asp

1609 Dirham are 145 Euro !!!
I pay in Strasbourg 14,90 Euro with unlimited Traffic.

Of course you should plan your CyberCenter close to an important 
crossroads of telecom infrastructure since Maroc Telecom will probably 
charge a lot for leased lines with such high bandwidth while you 
actually need dark fiber.

I know, I have all prices here.

Even if I have my own Backbone to my NetworkCenter and need for 
example some E1, E2 or E3 to my CyberCenters and InternetCafes, 
LL'a are too expensive. 

Speed:  E1 (1920kBit)   E2 (8,4MBit)E3 (34MBit)

Installation 4000 ¤ 13300 ¤ 17500 ¤

Local3000 ¤  5600 ¤  9700 ¤
   =  35 km 3200 ¤  6000 ¤ 11400 ¤
 35 - 100 km 3500 ¤  7300 ¤ 16800 ¤
100 - 200 km 4000 ¤  9200 ¤ 24900 ¤
 200 km 5200 ¤ 14000 ¤ 45100 ¤

So Leasd Lines are too expensive !

A friend of me in South-Afrika use 34 MBit RadioBridges (max 30-40km) 
and use Lucent ORINOCO Outdoor Routers for the Last-Mile Access...

Works quiet well. - No cable required. He told me, that the Cable was 
much more expensive as the 34 MBit RadioBridge and the Outdoor Router.

It depends, because

2)  If I support paralel to 1) commercial Users (End and ISP), I

http://www.wirelesguys.com/

The price is realy heavy (around 27.000 US$ each ) and they

What I need is a study about installing wired ! 
Dont know the price for the special cable, the Repeaters, ...

OK, I have already 26 Server prepared, but it is only for the

haven an idea, but no concept nor the skills you need. You will need 
probably consultants who help you to find a concept that works - in 
financial and technical concerns.

Some technical questions:

_ How will you do the accounting for wireless connections? Security?  To 
shoot from the hip I would recommend Maxina (www.maxina.de)
_ Did You know that Satellite Communictions has huge latencey ( 2 * 
36000Km distance ... I guess you won't be able to get a ping below 500ms)
_ Scalabilty? How many users can an accesspoint (Tsunami et al.) take? 
It's probably not an bandwidth concern ...
_ Did you know that 100% ISPs are generally nothing else than 99,x% 
ISPs when it comes to reality? The only advantage is, that you give you 
some pence if they violate their SLA.
_ Did you know that 54Mbit 802.11a doesn't really give you 54 Mbit in 
realiy? (huge overhead, all German readers: C'T benchmarked it)
_ For reliable wireless LAN you need line of sight or very close distance
_ 34Mbit and 155Mbit radio LAN Connection Equipment is far better than 
802.x but very expensive and maybe shitty to when it comes to noise 
concerns. LaserLinks are more reliable but don't work in foggy environments.

What you try to build up is an ISP + Carrier + Datacenter. Whooo much 
stuff. There specialists out that only do one of there three things and 
all have much to do with olny one area 

But that does not mean that you project is impossible, but what you need 
to know can't be learned in 8 weeks 
IMHO you will need Moroc Telecom in one way or the other. At all for 
your connecivity. It's pretty similar in all countries.

which scsi raid adapter?

2004-04-09 Thread Tinus Nijmeijers
hi,

I used to use Mylex  acceleraid cards (DAC960) which are in bf24 and in
the standard 2.4.* kernels. Now they are phased out by the new owners of
Mylex,  LSI.

so, what's a good scsi raid card that is in any of the woody kernel
install flavours and supported in standard (debian) kernels?

OSF for an ISP (was Re: ..idea; ddos spam hosts off Internet?)

2004-04-09 Thread Pulu 'Anau
To kind of get back to the ISP world a little bit, has anyone used this in the
way that's being recommended?  (Using the OS Fingerprint Netfilter patch to
block Windows machines sending to port 25).

We're currently getting slammed by Windows viruses and have thought about doing
exactly that, but it seemed to us that there are enough people using Exchange or
Sendmail.com's windows sendmail (let alone ftgate, etc, etc.) that doing this
would block legitimate mail almost instantly.

We've just been blocking hosts manually after the first virus.  I'm thinking
about writing a little script to:

1.  Get the offending IP address from amavis's logfile
2.  Check against a whitelist (like our own backup mx's)
3.  Do something like tcpping to the IP to see if it is a valid mx host
4.  If it doesn't pass checks 2 or 3, block the IP in netfilter for 72 hours

Other than the 72 hour checks it's pretty straightforward and seems (at least to
me) very unlikely to stop legitimate mail, while cutting those guys who send
40-50 viruses a day down to 1 every three.  

Does anyone see any problems with the above?  The major issue is bandwidth, some
of our customers host their mail servers on 32K links with 200+ users.

Sorry, it's not really about the spam issue discussed before, but it's strange
the synchronicity (os fingerprinting anyway) between my work and this list
sometimes.

Dave, your theory is right, you don't have to have an MX record in your 
DNS zone in order to receive mail, but Pulu wants to tcpping, so his 
idea is to check if there is an open port 25, i.e. check if the sending 
server is an mailserver. This would not be the case with infected 
outlooks ;) but also not for hosts behind NAT FW.
@Pulu: Is that your idea?

The problem is more that a sending host has not neccessarily to be an
receiver. (remindes me on goatse.cx ;-)) nor that is has to be smtp 
(submission et al?)

In Germany several large scale ISPs began to block all mail comming 
directly from an dialup ip, so I think it would be an accepted way to 
try what Pulu wants to do.

 Mylex sucks.
 
 huh? why?

Firstly, performance sucks.
My 960 had 128 Mbyte of RAM and still couldn't compete with GTD or IFT
RAID.

Secondly, the LINUX driver is kind of special.
While GDT controllers are recognised as scsi adapters, the Mylex driver
has it's own device naming scheme (this is, why it doesn't appear in the
SCSI submenu: it is not a scsi driver).
ICP offers a utility named icpcon, which is avaiable for linux and
enables full access to the GTD features/firmware (add/remove
physical/logical drives, etc while the os is running).
The MyLex driver offers a incomplete interface via the proc system, if I
remember this correctly.
Finally, for the benefit of Mylex, I have to say that mylex supported the
linux developer(s?) by donating/borrowing hardware.

 so, what's a good scsi raid card that is in any of the woody kernel
 install flavours and supported in standard (debian) kernels?

 Unfortunately, the GDT driver is not part of the woody distributiuon

The current sarge installer has full support for GTD adapters.
Beside that, you could recompile the debian kernel an copy it onto
disk/CD or preload GDT modules from floppy during installation.

 I recently replaced all Mylex 960 Adapters by GTD controllers.
 
 what happened to to Mylexen? dying in droves? (I've never seen a problem

My Mylex Controller currupted the entire RAID as it was actually
supposed to rebuild it...(RAID-5 with SPARE, 9 discs). The disc outage
itself was handled fine, though (and this is finally the reason why I
replaced the hardware. I didn't care that much about performance but
stability).

Right, and as I have written, I do only the study for this project. 
Then I will present this Project som people from the Maroc Gov. and 
some Finanicial/Technical Specialists to get a summary...

Some technical questions:

_ How will you do the accounting for wireless connections? Security?  To 
shoot from the hip I would recommend Maxina (www.maxina.de)

Oll Users have a fixed IP-Address and security is VPN/pptp (Included 
since Win98) and downlodable for Win95. 

Maxina I do not know and I will check it out.

_ Did You know that Satellite Communictions has huge latencey ( 2 *

Yes I know. Not funny for gamers...

_ Scalabilty? How many users can an accesspoint (Tsunami et al.) take? 
It's probably not an bandwidth concern ...

I offer only 64, 128 and 256 kBit. because my Experience with the 
Lucent ORINOCO maybe 2500 Clients with 64 kBit on one 54 MBit Channel. 

_ Did you know that 100% ISPs are generally nothing else than 99,x% 
ISPs when it comes to reality? The only advantage is, that you give you 
some pence if they violate their SLA.

YES.

_ Did you know that 54Mbit 802.11a doesn't really give you 54 Mbit in 
realiy? (huge overhead, all German readers: C'T benchmarked it)

But they have only Benchmarked the SOHO-Systems not HighEnd. 

You can not compare a Lucent ORINOCO or a Proxim Tsunami with 
Netgear, Dlink or Linksys. 

For example:The cheap 11 MBit WaveLAN cards like Linksys or 
Dlink hav only 10-15 mWatt.

The Lucent ORINOCO SilverCard 35 mWatt (required 
for the AccessPoints) and the GoldCard 50 mWatt.

Between two Netgear Cards you can have not more 
then 100 Meters with 3-4 MBytes/Sec and than you 
have a fallback to 5,5 MBit

Between two Lucent ORINOCO GoldCards you can have 
more then 600 Meters with 7 MBytes/Sec. 

For the cheap Cards you pay 22-40 Euro but for the 
Lucent ORINOCO GoldCard 109 Euro

_ For reliable wireless LAN you need line of sight or very close distance

The Lucent ORINOCO is tested in Kehl/Allemagne with up to 1300 Meters 
between the COR (OmniWave 10dBi) and ROR (YAGI 14 dBi) and between ROR 
(OmniWave) and Client without External Antenna up to 500 Meters. 

The Proxim Tsunami MP.11a is Tested in Strasbourg (Center) and do the 
job between the COR (SectorAntenne 120° 12dBi) and ROR (YAGI 16dBi) in 
a distance of up to 8000 Meters (I was not able to get bigger distances). 

Between ROR (OmniWave 10 dBi) and the Clients I have gotten more then 
1000 Meters with 256 kBit and it does not make a fallback to 48 MBit.

_ 34Mbit and 155Mbit radio LAN Connection Equipment is far better than 
802.x but very expensive and maybe shitty to when it comes to noise 
concerns. LaserLinks are more reliable but don't work in foggy environments.

8.000 km of FiberOptic cable ? 
I do not like to dream about the price...

But RadioBridges with 34 MBit do maximum 30 km and with 155 MBit 
around 20 km. So I need many of them. 

One of the Enterprises that I have contacted was 
http://www.itm-group.com/ and the Suggestion:

34 MBit Systems:Sagem, Witcom, Ericsson

155 MBit Systems:   Ceragon, Ericsson

Also he told me, that I need between 7 and 10 RadioBridges for a 
distance of 300 km because the turn of the Earth.

What you try to build up is an ISP + Carrier + Datacenter. Whooo much

My OWN Project was the Creation of a CyberCenter which contains:

1)  InternetCafeBased on Debian GNU/Linux
2)  Education Center for women  Informatic/Linux/Office
3)  WaveLAN-ISP Only Localy.

For this it is enough, if I have two E3 (34MBit), a 3Com NETBuilder 
II (8-Slot), one Proxim Tsunami MP.11a and the possibility of 
Serverhosting. 

Because Internet is realy expensive in Maroc and my Enterprise is 
non-lucrativ I like to drop down the price under the ADSL. 

But NOW:450.000 DH (41.000 Euro) for ONE E3. Two times more 
expensive as in France and fife time more

As far as I can remember you couldn't compile the drive statically in

I should be possible to put into the '/boot' directory on a floppy and
load it during the setup process (i.e. preload modules from floppy).

  The Controller used in the ProLiant ML330 series is an IDE-RAID and most
  of the logic is not done by the controller but by the driver itself.
  So performance will probably suck...
 
 My links refer to source to compile the drivers as a module.
 It's gpl released.

I just took a look at the files I got from LSI (who now own AMI) and the
driver is half GPL, half proprietary.

Quoting megaide-shimdriver-readme.txt:
LSI Logic's Shim driver has its raid intelligence as binary file
megaide_lib.o and the rest of the driver is open. megaide_lib.o can be
build with the open source to get driver image megaide.o.

Little BIG problem with Backbone

2004-04-09 Thread Michelle Konzack
Hello, 

because I am in paning of a CyberCenter Network in Marocco the idea is 
exploding !!! Exactly, I need very much Backbone-Power which can not 
provided from the Maroc Telecom

They offer me only E3 with 34 MBit !!!

And 34 MBit for 450.000 DH/month (41.000 Euro/month)

Only my Proxim Tsunami MP.11a (12 Access Points) support 216 MBit or 
effectiv 160 MBit and this only in one city !!!

Now there are some enterprises in Marocco which had ask me, why not 
installing a second Internet-Network !!! 

Oh yes, ist is no problem !!!
We need only a dual GigaBit Fiberoptic Sea-Cable from Espain to Marocco !

What a joke !

OK, crazy, but I have contacted CISCO for some routers ;-) and some 
other Manufacturs for Radio-Bridges (34 - 155 MBit and 1 GBit)

Now my Question:

Creating a Local GBit-Network in Marocco is generaly no Problem, it 
is not a big difference between it and my local network, exept I need 
a little bit more cable. 

BUT how does it work with the Connection to the Internet, exactly to 
the other Backbones ? 

Any Informations are Welcome...

in theory this is correct, but you should think about good manageable 
switches, so that you can build vlans. Without vlans your security in your 
network is not so good, because every computer can arpspoof and so sniff in 
the traffic of the other ips/nets you have conntected to the switch. Even 
Man-in-the-middle attacks are possible, if you don't think about vlans. You 
can also bind only fixed MAC Addresses to the switch ports, so that nobody 
can spoof another MAC/ARP of others, but I would prefer vlans :)

 BUT how does it work with the Connection to the Internet, exactly to
 the other Backbones ?

okay... in short: You need to contact the ripe and ask them for an AS Number 
and for an IP-Network for you.

If you got you own AS Number, you can configure your cisco router (or every 
other router which is able to use BGP (routing-protocol)) to annouce this AS 
to the next AS (which normaly is the AS of your uplink (Maroc Telecom for 
example). The AS of your uplink will annouce your AS to his next AS and so 
on, until every AS in the world nows how to reach your AS.

And you can announce over this AS Path your IPs (you got from the RIPE).

After you made this, you should be reachable from all over the world...

 Any Informations are Welcome...

I can only give you a short overview over the things you need... (bgp router, 
AS-Number, IP-Network). But you should inform yourself on other internet 
sites... just search for: bgp which stands for border gateway protocol or 
AS. Even the ripe site should be quite informative.  

In short: BGP is the protocol that makes the internet work, because all 
provider use this protocoll for their dynamic routing.

With bgp you can also use multiple uplinks, even with the same network. So 
that you can send and recieve pakets for you network over two uplinks for 
example. This can be used for redundancy and for combining multiple uplinks 
(if you need a lot of bandwidth)

Many things to learn...

And the the Office in Rabat/marocco:

mailto:[EMAIL PROTECTED]

IAM (Itisalat Al'Maghrib) is the Maroc Telecom and SeaBone has no 
own POP in Marocco. It is the Maroc Telecom. So this solution ist a 
little bit too expensive. 

And I know also Sprint has a PoP available in Morocco. There should be 
more. What about France Telecom, Telenor and Telefonica?

NO, all Provider are using the Network of the Maroc Telecom and because 
there is no second Provider they can make the Price how they want.

It is not good for Clients. 

See prices of ADSL:

http://abonne.menara.ma/adsl.asp

1609 Dirham are 145 Euro !!!
I pay in Strasbourg 14,90 Euro with unlimited Traffic.

Of course you should plan your CyberCenter close to an important 
crossroads of telecom infrastructure since Maroc Telecom will probably 
charge a lot for leased lines with such high bandwidth while you 
actually need dark fiber.

I know, I have all prices here.

Even if I have my own Backbone to my NetworkCenter and need for 
example some E1, E2 or E3 to my CyberCenters and InternetCafes, 
LL'a are too expensive. 

Speed:  E1 (1920kBit)   E2 (8,4MBit)E3 (34MBit)

Installation 4000 ¤ 13300 ¤ 17500 ¤

Local3000 ¤  5600 ¤  9700 ¤
   =  35 km 3200 ¤  6000 ¤ 11400 ¤
 35 - 100 km 3500 ¤  7300 ¤ 16800 ¤
100 - 200 km 4000 ¤  9200 ¤ 24900 ¤
 200 km 5200 ¤ 14000 ¤ 45100 ¤

So Leasd Lines are too expensive !

A friend of me in South-Afrika use 34 MBit RadioBridges (max 30-40km) 
and use Lucent ORINOCO Outdoor Routers for the Last-Mile Access...

Works quiet well. - No cable required. He told me, that the Cable was

This will kill my WaveLAN ;-)

solar cells and batteries and electric loiter cruise power, and

 OK, crazy, but I have contacted CISCO for some routers ;-) and some 
 other Manufacturs for Radio-Bridges (34 - 155 MBit and 1 GBit)

..sizes, weights, and power etc requirements?

It depends, because

1)  If I have only a NetworkCenter (4 x OC-3) for my CyberCenter 
project, I need only RadioBridges which supports E1, E2 and 
E3 and OC-3

2)  If I support paralel to 1) commercial Users (End and ISP), I 
need a bigger Backbone like 2 x 1 GBit which mean, I need 
GBit RadioBridges maybe up to 1,8 GBit too. 

http://www.wirelesguys.com/

The price is realy heavy (around 27.000 US$ each ) and they 
support not more the 20km and you need many Briges...
 
What I need is a study about installing wired ! 
Dont know the price for the special cable, the Repeaters, ...

..well, if you reel out a fiber spool or buy my relay drones, I guess 
you'll still need at least one gateway isp, a full set of new isp
servers, staff, and ofcourse at least one ip range, to set up your 
new Maroccan isp.  

I was thinking about minimum two independant and 100% redunant ISP's. 
OK, I have already 26 Server prepared, but it is only for the 
CyberCenter and can support up to 100.000 customers . 

Bigger Backbone need bigger Servers...
So 100 MBit FullDuplex will not enough.

..fiber you know, relay drones loiter at altitude with line of sight to
   
You mean via Satelit ?
I have read an Documentation that one Satelit Link can support 
up to 50 MBit. Is this right ?

But there are already concurence:  http://www.directsky.net/

both ends, carrying bridges, so both ground startions point link
antennas to that spot half way across the sea, say at 6ft, to 
stay out of the way of airliners etc.  Can even use wifi gear.

OK, this is logicaly

..and over cities, access point server drones, with bandwidth
throttling, loitering at anywhere from 1000 to 2ft? 
(Or 6ft, to stay clear of the airliner etc traffic.)

I can use the Proxim Tsunami MP.11a which sopports with the

Hello!
Before all this begins to get silly:
You are playing with amount of money which I would not concern as 
pennyware. As from you mails before, it's clearly to recognize that you 
haven an idea, but no concept nor the skills you need. You will need 
probably consultants who help you to find a concept that works - in 
financial and technical concerns.

Some technical questions:
_ How will you do the accounting for wireless connections? Security?  To 
shoot from the hip I would recommend Maxina (www.maxina.de)
_ Did You know that Satellite Communictions has huge latencey ( 2 * 
36000Km distance ... I guess you won't be able to get a ping below 500ms)
_ Scalabilty? How many users can an accesspoint (Tsunami et al.) take? 
It's probably not an bandwidth concern ...
_ Did you know that 100% ISPs are generally nothing else than 99,x% 
ISPs when it comes to reality? The only advantage is, that you give you 
some pence if they violate their SLA.
_ Did you know that 54Mbit 802.11a doesn't really give you 54 Mbit in 
realiy? (huge overhead, all German readers: C'T benchmarked it)
_ For reliable wireless LAN you need line of sight or very close distance
_ 34Mbit and 155Mbit radio LAN Connection Equipment is far better than 
802.x but very expensive and maybe shitty to when it comes to noise 
concerns. LaserLinks are more reliable but don't work in foggy environments.

What you try to build up is an ISP + Carrier + Datacenter. Whooo much 
stuff. There specialists out that only do one of there three things and 
all have much to do with olny one area 

But that does not mean that you project is impossible, but what you need 
to know can't be learned in 8 weeks 
IMHO you will need Moroc Telecom in one way or the other. At all for 
your connecivity. It's pretty similar in all countries.

To kind of get back to the ISP world a little bit, has anyone used this in the

We're currently getting slammed by Windows viruses and have thought about doing
exactly that, but it seemed to us that there are enough people using Exchange or
Sendmail.com's windows sendmail (let alone ftgate, etc, etc.) that doing this
would block legitimate mail almost instantly.
We've just been blocking hosts manually after the first virus.  I'm thinking
about writing a little script to:
1.  Get the offending IP address from amavis's logfile
2.  Check against a whitelist (like our own backup mx's)
3.  Do something like tcpping to the IP to see if it is a valid mx host
4.  If it doesn't pass checks 2 or 3, block the IP in netfilter for 72 hours
Other than the 72 hour checks it's pretty straightforward and seems (at least to
me) very unlikely to stop legitimate mail, while cutting those guys who send
40-50 viruses a day down to 1 every three.  

Does anyone see any problems with the above?  The major issue is bandwidth, some
of our customers host their mail servers on 32K links with 200+ users.
Sorry, it's not really about the spam issue discussed before, but it's strange
the synchronicity (os fingerprinting anyway) between my work and this list

idea is to check if there is an open port 25, i.e. check if the sending 
server is an mailserver. This would not be the case with infected 
outlooks ;) but also not for hosts behind NAT FW.
@Pulu: Is that your idea?

The problem is more that a sending host has not neccessarily to be an
receiver. (remindes me on goatse.cx ;-)) nor that is has to be smtp 
(submission et al?)

In Germany several large scale ISPs began to block all mail comming 
directly from an dialup ip, so I think it would be an accepted way to 
try what Pulu wants to do.

Rgds,
j.

how do you install a fresh machine with an ICP (not HOW but YOU :-)

 I recently replaced all Mylex 960 Adapters by GTD controllers.

what happened to to Mylexen? dying in droves? (I've never seen a problem
with them)

 Mylex sucks.
 
 huh? why?

Firstly, performance sucks.
My 960 had 128 Mbyte of RAM and still couldn't compete with GTD or IFT
RAID.

Secondly, the LINUX driver is kind of special.
While GDT controllers are recognised as scsi adapters, the Mylex driver
has it's own device naming scheme (this is, why it doesn't appear in the
SCSI submenu: it is not a scsi driver).
ICP offers a utility named icpcon, which is avaiable for linux and
enables full access to the GTD features/firmware (add/remove
physical/logical drives, etc while the os is running).
The MyLex driver offers a incomplete interface via the proc system, if I
remember this correctly.
Finally, for the benefit of Mylex, I have to say that mylex supported the
linux developer(s?) by donating/borrowing hardware.

The current sarge installer has full support for GTD adapters.
Beside that, you could recompile the debian kernel an copy it onto
disk/CD or preload GDT modules from floppy during installation.

 I recently replaced all Mylex 960 Adapters by GTD controllers.

My Mylex Controller currupted the entire RAID as it was actually
supposed to rebuild it...(RAID-5 with SPARE, 9 discs). The disc outage
itself was handled fine, though (and this is finally the reason why I
replaced the hardware. I didn't care that much about performance but
stability).

Hello!

Before all this begins to get silly:
You are playing with amount of money which I would not concern as 
pennyware. As from you mails before, it's clearly to recognize that you 

I had a talk with the Ministry of Communicatin in Rabat and he ask 
me about the costs. 

I have answerd some hundred million Dirham. 

A littlebit silence and than he ask me How many hundred million ?

OK, between 8 and 12. 

He was meaning, thats a real chiffre.

haven an idea, but no concept nor the skills you need. You will need 
probably consultants who help you to find a concept that works - in 
financial and technical concerns.

Right, and as I have written, I do only the study for this project. 
Then I will present this Project som people from the Maroc Gov. and 
some Finanicial/Technical Specialists to get a summary...

Some technical questions:

_ How will you do the accounting for wireless connections? Security?  To 
shoot from the hip I would recommend Maxina (www.maxina.de)

Oll Users have a fixed IP-Address and security is VPN/pptp (Included 
since Win98) and downlodable for Win95. 

Maxina I do not know and I will check it out.

_ Did You know that Satellite Communictions has huge latencey ( 2 * 
36000Km distance ... I guess you won't be able to get a ping below 500ms)

Yes I know. Not funny for gamers...

_ Scalabilty? How many users can an accesspoint (Tsunami et al.) take? 
It's probably not an bandwidth concern ...

I offer only 64, 128 and 256 kBit. because my Experience with the 
Lucent ORINOCO maybe 2500 Clients with 64 kBit on one 54 MBit Channel. 

_ Did you know that 100% ISPs are generally nothing else than 99,x% 
ISPs when it comes to reality? The only advantage is, that you give you 
some pence if they violate their SLA.

YES.

_ Did you know that 54Mbit 802.11a doesn't really give you 54 Mbit in 
realiy? (huge overhead, all German readers: C'T benchmarked it)

But they have only Benchmarked the SOHO-Systems not HighEnd. 

You can not compare a Lucent ORINOCO or a Proxim Tsunami with 
Netgear, Dlink or Linksys. 

For example:The cheap 11 MBit WaveLAN cards like Linksys or 
Dlink hav only 10-15 mWatt.

The Lucent ORINOCO SilverCard 35 mWatt (required 
for the AccessPoints) and the GoldCard 50 mWatt.

Between two Netgear Cards you can have not more 
then 100 Meters with 3-4 MBytes/Sec and than you 
have a fallback to 5,5 MBit

Between two Lucent ORINOCO GoldCards you can have 
more then 600 Meters with 7 MBytes/Sec. 

For the cheap Cards you pay 22-40 Euro but for the 
Lucent ORINOCO GoldCard 109 Euro

_ For reliable wireless LAN you need line of sight or very close distance

The Lucent ORINOCO is tested in Kehl/Allemagne with up to 1300 Meters 
between the COR (OmniWave 10dBi) and ROR (YAGI 14 dBi) and between ROR 
(OmniWave) and Client without External Antenna up to 500 Meters. 

The Proxim Tsunami MP.11a is Tested in Strasbourg (Center) and do the 
job between the COR (SectorAntenne 120° 12dBi) and ROR (YAGI 16dBi) in 
a distance of up to 8000 Meters (I was not able to get bigger distances). 

Between ROR (OmniWave 10 dBi) and the Clients I have gotten more then 
1000 Meters with 256 kBit and it does not make a fallback to 48 MBit.

_ 34Mbit and 155Mbit radio LAN Connection Equipment is far better than 
802.x but very expensive and maybe shitty to when it comes to noise 
concerns. LaserLinks are more reliable but don't work in foggy environments.

8.000 km of FiberOptic cable ? 
I do not like to dream about the price...

But RadioBridges with 34 MBit do maximum 30 km and with 155 MBit 
around 20 km. So I need many of them. 

One of the Enterprises that I have contacted was 
http://www.itm-group.com/ and the Suggestion:

34 MBit Systems:Sagem, Witcom, Ericsson

155 MBit Systems:   Ceragon, Ericsson

Also he told me, that I need between 7 and 10 RadioBridges for a 
distance of 300 km because the turn of the Earth.

What you try to build up is an ISP + Carrier + Datacenter. Whooo much 
stuff. There specialists out that only do one of there three things and 
all have much to do with olny one area 

;-)

My OWN Project was the Creation of a CyberCenter which contains:

1)  InternetCafeBased on Debian GNU/Linux
2)  Education Center for women  Informatic/Linux/Office
3)  WaveLAN-ISP Only Localy.

For this it is enough, if I have two E3 (34MBit), a 3Com NETBuilder 
II (8-Slot), one Proxim Tsunami MP.11a and the possibility of 
Serverhosting. 

Because Internet is realy expensive in Maroc and my Enterprise is 
non-lucrativ I like to drop down the price under the ADSL. 

But NOW:450.000 DH (41.000 Euro) for ONE E3. Two times more 
expensive as in France and fife time more
