For what i know one need a special player to decode the streams from
vlc allthough ive heard that with a plugin it should be possible for
windows users to play native vlc streams with windows media player
(not confirmed though). We use the videolanserver when we need to
stream high bandwidth quality streams on internal networks allthough i
would use another media format than MPEG1/2 for streams on internet. 

Real Networks has a free Streaming media server (limited to maxium
1mbit/sec) and your customer can download free Real producer encode
content in Real format.

You need to find out which media format your customer wants to use and
then pick the best streaming server for that format.

Our customers have diffrent needs so we bill both pr/mb and used
bandwidth. Usually as hosting provider you pay for the total amount
of bandwidth. Streaming can be very very bandwidth extensive so you
should proberly try to find out how many concurrent users your
customer wants to support and if its adult content keep and eye on
your logs and bandwidth usage ;-)

I work for a streaming media provider and we run the following
streaming servers on debian woody :

Helix Streaming Server
Real Server 8 (will only run on 2.2.x kernels)
Darwin Streaming Server 4

They all work on debian without any problems.

Beside that we run windows media services 4.1 and windows media
services 9 (windows 2003) ugh!

Hey There listmembers

As a burdend debianadministrator ive begun to use dsh to update and
install packages on our debianboxes but im experincing some very
strange problems. On some machines i will get the following error when
trying to install debian packages :

xxx: Need to get 0B/879kB of archives. After unpacking 1769kB will be
used.
xxx: dpkg: `ldconfig' not found on PATH.
xxx: dpkg: `start-stop-daemon' not found on PATH.
xxx: dpkg: `install-info' not found on PATH.
xxx: dpkg: `update-rc.d' not found on PATH.
xxx: dpkg: 4 expected program(s) not found on PATH.
xxx: NB: root's PATH should usually contain /usr/local/sbin, /usr/sbin
and /sbin.
xxx: E: Sub-process /usr/bin/dpkg returned an error code (2)

Apparently its something about the remote executing of programs and
the $PATH variable. I cant really nail this problem since to my
knowledge the machines is identically. Can anyone see whats happening?

We both uses the 570 and the 580 here with debian stable. Allthough i
had some troubles getting the driver in the stock kernel to work with
580 (i ended up downloading driver source from d-link italia and
compile it against the kernel version i was running). The 570 is rock
stable we are using it in gateways and firwalls all around our company
and i have nothing bad to say about it. It uses the tulip driver in
the kernel.

The software they use for testing open relays is pretty advanced.

The same test on a scsisetup much like the above just with scsidisk :

*:~# hdparm -T /dev/sdb5 

/dev/sdb5:
 Timing buffer-cache reads:   128 MB in  0.95 seconds =134.74 MB/sec

/dev/sdb5:
 Timing buffered disk reads:  64 MB in  3.42 seconds = 18.71 MB/sec

When it comes to real world test my scsibased system is almost twice
as fast as the idebased one :)

Yes the disk reads is a more realistic real world test :

 Timing buffer-cache reads:   128 MB in  1.23 seconds =104.07 MB/sec
guf:~# hdparm -t /dev/sda5

/dev/sda5:
 Timing buffered disk reads:  64 MB in  5.84 seconds = 10.96 MB/sec

The above result is from the Ultratrak Tx8 (TX8000 now) with 8 60 Gigs IBM
deskstar 7200 rpm in raid 5. Kind of slow if you ask me.

Maybe i should give them a try in a near future? The promise Ultratek

The array is connected to server via SCSI. It looks like a very big

Sorry it was 15MB/sec but thats still not very good.

I spoke to a guy somewhere in asia and him and his friend (they
worked for a large company forgot the name now) conducted some
benchmarktests that show exactly the same as mine so i guess its just
the speed that this array can do. To my luck we use this array for
storage now and not so much for serverbackend diskcapacity.

yeah maybe? The thing is we will never know since the promisearray dosnt tell

yes indeed but still i was stunned when i heard what the solution
was. Im use to work with 1-class serverhardware and ive never done

If you are thinking on this one ->
http://www.promise.com/product/product_detail_eng.asp?productId=90&familyId=6

Dont buy it! It as simple as that. 1 year ago i bought one of those
bastards from promise and its slooow. Im running it as filer on a
debian 3.0 system filesystem xfs and i havent been able to push it to
a sustain throughput on more than 3MB/sec. This is with 8 60GB IBM deskstar
7200rpm disks in raid5. Recently a disk crashed on me and the hole
array went offline allthough the manual says it should continue to
function. NOT TRUE! I relplace the broken drive with a new and the
promisearray began to rebuild i thought i where homesafe. After
rebuilding in 15 hours the array went offline again and nothing i did
got it back?? I called localshop where i bought it nobody could help
me they suggested that i contacted promise in netherlands. Story
continues.

Promise in netherlands where quit helpfull but what they suggested got
me pulling out my hair!!! (what i have left of it). They suggested
that i deletede the array, created a new and saved it then just after
saving it i had to pull out the powercord in the back so the array
wouldn't initialize. I would not belive what i was hearing. Pulling
out powercord while the array is initializing sounds like a hugh hack
to me but i did it just because i didnt knew what else to do. It
actually worked so now im back to the good old slw promisearray
and after a xfs_repair my filer was up and running again. 

Next time i have to buy ideraid ill try 3ware for sure.

building a gateway

2001-09-10 Thread Thomas Kirk

Hey There Listmembers

Im currently examine how to build a internetgateway for my office
using linux kernel 2.4.x + iptables + NAT + DHCP. The gateway will be
connected to the internet via ADSL :


  +-+
  | ADSL|
  +-+   
 |
 |
   eth0 
   +---+
   |GATEWAY|
   |IPTABLES   |
   |DHCP + NAT |
   +---+
|   |   |
|   |   |  
 eth1 eth2 eth3

This is a rough sketch of the system. Im gonna be runing DHCP on all
the interfaces eth1,eth2,eth3. So now i wanna know are there any
considerations i should be aware of? Have anyone on the list made
something like this. I would like to hear any experince people have
with iptables, DHCP and, nat.

Thanks in advance

Even though GFS has supported SMB/CIFS i think it would be rather overkill
since we actually dont need the synchronizes between servers we will only
have data in one place and what is one of the most important features for us is
read acces because we are bascially using this NAS as a big harddisk our

Building NAS

2001-07-18 Thread Thomas Kirk

Dear Listmembers

Im new to this list so let me introduce myself. My name is Thomas and
i work for a small streaming media company in denmark. Currently im
investigating how to  build a NAS. In this investigation
some questions has come up which im not currently able to
answer. Neither have i had the luck to find any answers to my question
on the net. Let me try to describe the setup we are aiming for and
then you guys can comment on that if you have any experince in the field.

Hardware setup  :

HP LH3 (now LH3000)
Dual Pentium III 650mhz
512 Ram ECC
Netgear GA620 (gigabit networkcard)
Harddisks in raid 5 array
Connection to streaming servers via Gigabit networkswitch
and 10/100mbit networkcards in the servers.

Hence the fact that we have a mixed linux/windows (only one) ;-)
enviroment im aiming for SMB/CIFS to share the disk with the
windowsserver and NFSv3 for the unixboxes.

Software setup  :

OS  : The NAS running Debian 2.4.x 
Filesystem  : XFS/ReiserFS/Ext3FS ? 
Networkprotocols: NFSv3 and SMB

So now my questions :

1) What kind of network overhead can i expect to see on the diffrent
network protocols?
2) Currently im heading for Ext3fs as filesystem but ive been looking 
at XFS which sounds very promising too. If anyone have some experince 
and can spread some light on it i would be very grateful.
3) Where in the systems is it most likely that i will experince
bottlenecks?
4) Just general comments on the system and if anyone have any
experinces building a NAS. I have looked at VA-linux NAS solutions
which in overall look alike the system i thought i would build for my
company allthough i think their systems are way to expensive which is
also why we are going to build our own ;-)
