[SLUG] Ubuntu kernel source and binary packages

[John Clarke]

Hi all,

I installed Ubuntu Hoary last week -- my first installation of anything
other than Redhat for close to ten years -- and I'm having trouble
finding matching kernel source and binary packages.

apt-get-install linux-686-smp gave me a kernel which says it's
v2.6.10-5.

apt-get-install linux-tree gave me source which says it's v2.6.10-34.1.

I've searched but can't find source for 2.6.10-5, or binaries for
2.6.10-34.1.  Do either of these exist, and if so, how do I get them?


Thanks,

John

[SLUG] IPSEC expert wanted

[Grant Parnell - EverythingLinux]

Need to get hold of someone who's experienced at setting up IPSEC, 
especially with Sonicwall firewalls. This is for a small job, and includes 
training me what's involved.

The platform they'll be using is Debian and I'm suggesting using the 
latest release (as of this week) as soon as we've downloaded enough of it. 
We'll be selling CD/DVD boxes of it as soon as we can get the images and 
send it off to be pressed in bulk.

Currently they have one Debian unstable on X86-64 which is causing grief 
with package dependencies so they'll re-image with the 32 bit. The other 
is a RedHat AS 2.1 box which they're reluctant to let us touch.

You've lost me here.  Why does he need to install a new (non-standard) kernel?

To use apt or to use gcc?!

Do, as root:

yum install gcc

and it will do the necessary for you.

Easy eh?


You should use yum (or apt) anyway, just to keep up to date.

Have a read of the 'Keeping up to date' doc
at http://fedora.redhat.com/docs/updates/

If you're feeling adventurous, you can setup your own yum repos.
'Yam', from http://dag.wieers.com/ might help.

It boils down the what sort of firewall/protection the Netcomm has built 
it. It most likely has something, but may not be as secure as you want 
it. Scan your external IP address and see what is open/closed/filtered.

Hi Steve,

The modem handles the PPPoE side of things. Make sure you have your
modems LAN address set as your default route.

It's just like connecting to any vanilla network.

Re: [SLUG] SQL Brain teaser...

[Grant Parnell - slug]

My god... there's some good ideas there. For now I opted for processing 
outside of SQL by basically breaking the day into 1 minute time slots and 
looking at how many orders were currently being processed in each time 
slot. Next I iterated again and counted up the minutes for each order such 
that for each real minute the attributed time was t/n where n was the 
number of current orders being processed. Then I simply averaged the 
attributed times for each order.
I can get away with this approach because the data set is pretty small and 
it's only twice through the data.

Essentially we agree on only looking at times of the day where packing 
activity is occurring. The jury is out on whether you can assume the 
orders were processed sequentially based on docketdate.

We'll never know, based on this data, how long each specific order took 
but then I don't care - baring exceptional cases (eg 2 hours).

Still, I'll try implimenting your approach for comparison's sake. It'll 
certainly be interesting.

To those who responded on-off list thanks.

I completely underestimated how memory hungry Evolution is, also

Then fire up vmware and it is cpu hungry. At 4 years old I think a new

Now i"m watching closely I go to 512 meg ram used and 912 meg swap

If you are referring to this news item:

" ...The Digium TE110P has now been fully certified (A-ticked) for
connection to the PSTN."

(quoted from the site pasted above)

The TE110P card, as far as I know, is only for connecting to a ISDN
10-30 service, not plain PSTN (FXO). The TE110P is advertised for $670
by ATP. The FXO module on the ATP site says "This module is undergoing
A-Tick certification". If the FXO module only (for the TDM400P) is
advertised for $123 now, I would imagine it'll jump to over $300 once
it is A-Tick certified, though there's been rumours the FXO would get
A-Tick certified for over a year. I wouldn't hold my breath.

No, thats for the fixed IP.

Another great source of VoIP info is (funnily enough):

http://www.voip-info.org

It really depends on what you want to achieve. If you just want to
experiment and see how it works, you can get away with using a
software VoIP client, like iaxComm (for Linux/Win/others), X-Ten's
X-Lite (www.xten.com), Firefly, and of course there are many more
floating around.

The Digium cards will help you if you want to receive and make calls
through your PSTN line (I'm talking about the FXO cards here),
however, they are not A-Tick certified so you couldn't use them in
Australia (legally).


You can buy Digium cards in AU at http://www.austechpartnerships.com/atp/



You will also find a bunch of VoIP providers around Australia that
will give you a direct indial number for a low monthly fee (such as
$10/month) so you can receive calls to a number provided by them to
your Asterisk server. This is pretty cool and costs less than the
monthly rental from [insert telco]!

There is also the #asterisk IRC channel on irc.freenode.net where you
can occasionally get some good help from the guys. Always check the
voip-info.org wiki, lots of good info on there.

Good luck and hope this helps!

Another option you have is to get ISDN (2 lines) and the AVM Fritz!PCI
Card which *is* A-Tick certified. Only problem is it costs about 400%
more than the real cost of the card, since it has the glorious A-Tick

I'm not quite sure what you mean by this. I'll explain what I meant by
this: If you want to plug in your standard PSTN line into your system
to receive and make landline calls through Asterisk, you will need a
FXO card and the Digium card, at least, is not A-Tick certified (last
time I checked anyway). If you just want to make calls through VoIP,
you can just use a VoIP provider like Freshtel and receive calls
through VoIP via a DID provider and you'll have no need for a FXO card
at all. There are providers around, such as www.atp.org.au, that offer
flat rate local and STD calls as well as DID numbers for a low cost,
making the need for a FXO card unnecessary, more so if you're just
experimenting.

Hi Leslie,

Providing you have broadband connection to the Internet - faster the 
better - no need to re-install.
I am using Fedora's and Redhat's and have save me lot's of headaches 
with installations.


Just try, the following procedures:

As root do this one first if you have not done yet:
#rpm -Uvh 
http://atrpms.net/dist/fc3/atrpms-kickstart/atrpms-kickstart-25-1.rhfc3.at.i386.rpm


Then,

#apt-get update
#apt-get dist-upgrade
#apt-get install kernel=2.6.10-1.770_14.rhfc3.at (There is a 2.6.11.XXX 
but has problems).


Then,  re-boot your linux to the above kernel.
Then you may install/upgrade any development module you like, e.g.,
#apt-get install gcc (or the like).

'apt-get install' is a smart user-tool that knows dependencies and will
install them when required. No need to figure out yourself. If you
are not familiar with 'rpm' command it is usefull to read up on it.

Hope this helps.
