Problem with two lan networks and access to ap

firefox

You can't see the wifi clients from the wired network because because the protocol Windows uses to discover network shares doesn't span subnets.

in My work
There were about 2000 computers connected
Over 50 different networks

I tap the icon "Network" on the computer
I see all the networks
Then click on the network icon
And see all the computers on the network

I guess strains because they are connected to servers
So I guess the server tells computers where they are at,

Is there something similar to pfsense

@stephenw10:

I would try adding the route again to the access point. I should do nothing or fix it. The fact that it killed everything last time you tried it implies something wasn't right.

I prepare a file with all the screenshots of this router
I will attach it to the next post
See what I did there
What should be done

I use Linux not Windows

How can you upload here a presentation weighs 2.8 MB
Or upload more images in a single message

Here is a link to download the pdf file
With a screenshot of the router's management interface

Exactly.

No. (I assume you mean for pfSense)

You are probably using the Windows SMB protocol for file shares in Linux, though there are others, so the same applies. You need a domain controller to register the available shares across all subnets and distribute that information. This isn't my forte though. ;)

Here is a useful thread: http://forum.pfsense.org/index.php?topic=22064.0

I would try adding the route I described earlier into the AP routing table again. I can't see how it could possibly break anything. It may not work but it should cause any harm.

Is the Avahi package can fit

I read in this thread
About a similar problem

http://forum.pfsense.org/index.php?topic=60967.5

When I read the thread you gave a link for it
It said it is related to DNS

stephenw10

Avahi does what you want but only for the mDNS protocol. This is used primarily by Apple but also by various media streamers, NAS boxes etc. Apples Bonjour file sharing service uses it. Reading that wiki page I see that it also supports Linux's nss so you might be able to use that. I've never tried, I would have to do a lot more reading before attempting it! ;)

You really do not want to rely on broadcasts to keep track of 2000 computers and their shares.

You need to get it mapped by IP and just access shares with IPs.

stephenw10

I think the 2000 machines were just given as an example of how network shares can work perfectly across any number of subnets as long as some central server is tracking and distributing them.
Using Avahi and NSS might be a solution if your network is all Linux/BSD. Interesting prospect.

SAMBA4 might be something to look at as a stand-alone DC.

stephenw10

Yes that would be the correct way to do it. It does mean you need an always on machine in addition to pfSense.
JimP posted, a long while back now, about trying to make a cut down samba package that only ran as a WINS server. I don't think he could make it work which is a shame since it would fulfill these duties perfectly.

I use SAMBA and I have a WINs server set up. To save trouble, I have it running in a VM thats doing a whole lot of other things also.
UBUNTU is really simple to do this with. So is Mint and Centos. Or it would also be simple enough to do it with the LINUX computer he is using as a work station currently. It would be invisible to him once he set up the samba.conf Only thing is, its not going to handle more than just 1 subnet unless he is magician. Thats the part I'm not clear on. How many subnets are there?

(I maintain this, but I don't ACTUALLY need it)

stephenw10

It should work fine as long as you specify the IP of the WINS/samba machine in the DHCP settings from the other subnet. In his case wireless clients can contact a samba server on the wired side by IP no problem so as long as they are set to use that for netbios queries it should work. Of course it relies on having the samba machine up before anything else tried to connect.

Reading some docs it seems the only part of samba neccesarry to get this working is nmbd. Someone must have made a FreeBSD package for that already I'm thinking.

I already have Samba on Linux computers
But it does not help

They only see computers on their network

@kejianshi:

It was an example of computer network at work

I have a computer with a virtual machine on it
Not the most powerful computer
Because there is only one machine
And the computer does not carry

I will try to add another one and see if the Avahi package works

stephenw10

If you're already running a samba server, I imagine any Linux machine could do that, the configure it to be a WINS server. Then add the IP address of that machine to the DHCP server config on both the wired and wireless networks. There's a field for that marked 'WINS servers'. You will have to make sure that machine is always on (or almost always). You won't need a powerful machine to do this it should require almost nothing by way of resources.

Avahi will not help if you are using SMB shares.

I'm on Samba version 3.6.3

I think you'd need to get to version 4 to attempt this the way you want.

stephenw10

What makes you think that? Samba has had WINS support for like forever. ;)

Steve

kejianshi

Yeah - WINs works for me, per subnet. But I can't see whats on 10.10.10.0 from 10.10.11.0 thats all I'm saying.
For me anyway… (I gave up trying a while ago)

My last use for it was getting netbios over TCP with Openvpn - Works fine for that for me. (but plugging in IP is more reliable/faster)

stephenw10

I'll defer to your experience since I've never actually tried it but I can't see why it wouldn't work in theory. ::)

May be we are not on the same wavelength

When I said that I have Samba
I did not mean another computer
I meant Linux software installed on ubuntu that allows me to share

@stephenw10:

Avahi will not help if you are using SMB shares.

what is "SMB shares"

kejianshi

SAMBA "installed on ubuntu that allows me to share" = SMB share

But with samba shares you have to take some steps in the samba.conf file to make the workgroup correct, handle your printers, identify and name your file shares, AND you have to make it allow access without passwords unless you want passwords required.

That same samba.conf is also where you would set up WINs parameters if you want.

kejianshi

Do you already have file and printers shared? If so, what are you using to do that?
