Hi all,

Are there plans to implement the anycast feature set in ip for IPv6
anycast addresses?

Thanks in advance,

Re: [LARTC] List fault?

Hi,

has anyone contacted vger.kernel.org about lartc list creation?

kernel.org hosts wikis (and bugzilla) too.
seems like a good choice to me.

Sorry guys, but I have to support Michelle here and refrain that anyone
not familiar with the "Reply-To" problem in the context of mailinglists
do a quick google on "Reply To munging". It's really just some ugly
workaround for old/broken MUA to set Reply-To for a mailinglist pointing
back to itself. 

Please don't!

Hi

I sort of agree. This list just magically came back to life. Why? Did
someone flip a switch? Who is that person? Will they turn it off
again?

Also, regarding the site, its very static. I think a wiki could
replace it and breath some new life into it.

[LARTC] Moving the LARTC list to a new domain.

2011-11-24 Thread Grant Taylor
/If/ this mailing list is to move to a new domain, I'd suggest that we 
move it to something at lartc.org if at all possible.  Rather than 
moving it to a different domain that is not directly associated with 
LARTC or portable.


Doing that would keep the mailing list address (hopefully 
la...@lartc.org) dis-associated with any other entity and would allow it 
to move from location to location as the need arises over the coming years.

Sorry, my bad.


No problem.  We are all human.


I want to block, drop, what ever, Microsoft networking... wins? but I do
want to permit internet networking (for what of some better terms.


Ok.

So we are only talking about filtering TCP / UDP ports 137, 138, 139 and 
445.  (Isn't M$ networking fun...)



I don't want users on the 2.0 network to see the 'shares' on the 3.0
networks in 'network neighbourhood'.


I think I know what you are after.


I know this could be achieved by simply putting everyone in different
work groups rather than the default of 'workgroup' (or 'home' depending
on what version of windows you're using). But I don't control the
computers, so I can't do that.


Now we are getting in to some M$ networking issues.

I think the proper term (as I (mis)understand it) that you are after is 
"browse".


Just because the computers are in a different workgroup does not mean 
that they won't be able to see each other.  In fact, workgroups mean 
little any more.  If any thing, the "workgroup" is sort of (very rough 
analogy) like your local subnet in that it takes marginally more effort 
to go out side of it, but still very possible to do.  -  In short, using 
different workgroups would not suffice for what you are wanting.



If user 2.35 sets up WAMP on their PC, I do want 3.45 to be able to see
that. http://192.168.2.35/ ... blar :)


*nod*  TCP / UDP ports 137, 138, 139 and 445


What I want is... When a user browses the "network" (windows term), I
want them to see DonsNAS\192.168.x.0_Share That's where I eventually
want to end up.


Heh.  Now more M$ networking fun.

I think you are about to run in to the network visibility vs 
accessibility issue.


Specifically, if you want computers to be able to "browse" the network 
(neighborhood) and find computers to access, you are going to have to 
have a functional browse master list.  Complicating this is the fact 
that you have multiple networks (subnets) trying to tie together.


In the end I think you are going to end up with a single unified browse 
maser list that all the computers are on.  Now, that does not mean that 
the computers will be accessible, just that they are on a list.



Everyone on the x.0/24 network gets access to 1.xGb of shared space
where they can put stuff they want to share with everyone else on their
network. People on y.0/24 will have their share on the same NAS (which
is actually a nice Debian box running samaba). The share is to be fully
open to everyone in x.0 but not visible to people in y.0 etc.


Ok.

So you are exploiting some of Samba's features as a central file server.


Think in terms of a block of apartments where each apartment is getting
a x.0/24. I'm wanting to give all the users in apartment 1 a network and
some shared space so they can transfer files etc but I don't want the
people in apartment 2 seeing the files of apartment 1. However I don't
have control of the computers, so I can't do stuff like ACLs etc.


Heh.

Isn't multi-tenancy networking fun?


I don't want them to be able to 'browse the network', errr... I don't
want them to be able to "browse" the other networks.


Here "browse" can mean multiple things: 1) see the computers on a list 
that are connected to the network and 2) access a given computer and see 
the contents there on.


I think you are going to have to live with #1 and use IPTables to 
control #2 via firewalling.



Ya, that's not what I want. I only want to drop the smb traffic. Is that
port 137? or do I need to drop more than that?


To be save, I drop both TCP and UDP for ports 137, 138, 139 and 445.

(We actually only need to block a subset of those ports, but I don't 
bother to remember exactly what is needed and just block those 8 ports 
and have been fine for the past decade.)



If I do what you just said then skype between networks will break won't
it? or it will travel out the public IP and transit to another peer?


As I broadly said it, yes.  However, if we refine it to be for the 8 
ports in question, no.


Question:  Do you want to control the 2., 3. and 4. network's access to 
the the 1. network so that they can only get to the servers IP, or can 
they access the entire 1. network?


At this point, I think your firewall rules will be such that you first 
allow SMB/CIFS traffic (from any network) to the 1. network -and- from 
the 1. network (to any network). and then you drop / reject any other 
SMB/CIFS traffic.  (You may want to refine "1. network" to be "the NAS 
server's IP".)



Thanks for the help man :)


You are welcome.



Grant. . . .


P.S.  For the record, you really are crossing two completely different 
network layers.  One is the TCP/IP & routing layer and the other is the 
M$ Windows Networking layer.  Doing this can be interesting (and I don't 
mean in a good way), somewhat difficult, and sometimes prone to 
compromise (as in I don't like it but it works, not the security breach) 
and failure.
