Installation and Upgrades / Add more disk space help needed

« on: December 01, 2010, 06:42:31 pm »

I'm way over my head here.

I have zentyal on vmware.
I originally had a 50gb driv
I have now increased this to 256gb.

My /dev/mapper/home is about 40gb
BUT this is where all my samba shares are and I need this to be about 200gb (in other words - bigger)

I've got no idea what to do. If this was windows server i'd be fine but am new to linux and need some help.

Here are your problems:

C:\Users\P>nslookup yahoo.co.uk
Server:  UnKnown
Address:  10.203.129.68

1.) It can't see the name of your DNS server
2.) It can't trace past your DNS server or gateway
3.) On your OpenVPN IP details, everything is on the same subnet except for your DNS server.  With this configuration, specifically the 255.255.255.0 netmask, you will be unable to reach that DNS server from the OpenVPN adapter as its on a different subnet.
  This is incorrect. I can ping 192.168.1.254 fine. This is my ADSL router.


You need to find out how to assign a DNS server in the same subnet... maybe create a virtual interface for that address?  I'm not sure what exactly the fix is, but as I've said from the beginning, it's definitely something with the DNS setup.

Basically, this is what is happening when you try and go on the net:

Your computer is saying "My IP address is 192.168.250.2, and I want to go to yahoo.com.  Let me get the IP address for that".  Then it says "My DNS server is 192.168.1.254, let me try and connect to that..." and it sees that it can't reach that subnet, and says "Can't get there" and shrugs its shoulders.

     again, I can get to 192.168.1.254 just fine.


Your DNS server needs to either be a 192.168.250.* address, or something on the VPN server needs to give VPN clients a way to reach that other subnet.

does anyone else have any idea whats going on.

Additional Information.
If on my windows pc, I run these commands

route delete 0.0.0.0
route add 0.0.0.0 mask 0.0.0.0 192.168.1.3    (this is my ebox)
and then try to trace route on yahoo.co.uk
then this works fine

C:\Windows\system32>tracert www.yahoo.com

Tracing route to eu-fp.wa1.b.yahoo.com [87.248.122.122]
over a maximum of 30 hops:

  1     1 ms     1 ms     1 ms  Zentyal-SBS-Server.config [192.168.1.3]
  2    22 ms    99 ms    99 ms  BeBox.config [192.168.1.254]
  3    18 ms    20 ms    27 ms  10.1.2.161


so ebox can see my router
and can access the internet...

but when on VPN, I can not
Yet I can ping my router

So when I connect to VPN, the IP that is assigned is 192.168.250.2
and the default gateway becomes 192.168.250.1

If I use the same principle above without vpn and deltet and add my default gateway to 192.168.250.1, I again cannot access the internet

So Im guessing the problem, lies with the 192.168.250.x subnet not knowing how to access the internet.....

« on: October 18, 2010, 02:32:30 pm »

I've followed this and I can access my advertised network.
I cannot however access the internet through VPN and I dont know why..

I know before I added the change of gateway above , I had internet access...

Why would I want to route my internet traffic through VPN?
I want to access my local advertised networks 192.168.1.x and have internet access locally...
Dont I?

I cant see why I would need to route all data through VPN..


Argh Im stuck.
VPN now works ok and I can access my machines on the LAN through VPN
but have no internet access locally and cannot resolve DNS queries or ping external IPs.

Not quite..
The DNS machine you refer to is my ADSL router.
192.168.1.254 which I can ping and connect to.
remember - this is part fo my allowed 192.168.1.x network

I cannot resolve DNS names such as yahoo.co.uk
OR ping an EXTERNAL IP address.

I can access all my internal network over VPN.

Thanks

I don't think this is correct as the network is added to my list of accessible networks under vpn settings and yes I can ping all of my 192.168.1.x network including the router.

I cannot however ping an external internet address not resolve a DNS name such as yahoo.com
I can change the adapter DNS to opendns server IPS but then the fact I cannot ping an external internet IP means this is irrelevant anyway.

Installation and Upgrades / Cannot access internet over vpn

« on: October 17, 2010, 08:07:12 pm »

Hi, I need a little help with VPN.
I've followed the VPN install video which went fine and can connect to VPN no problem.
I give out addresses using 192.168.250.x and advertise my internal network 192.168.1.x

The video does not mention anything about the fact that you have to make code changes in order for this to work which in the Microsoft SBS vs Zentyal scenario - SBS is always going to win hands down.

Anyway - after code changes, all traffic is now routed through the VPN and I can ping my lan machines.

So - now one problem.
I cannot access the internet and i've no idea how to fix this.
Even changing the ethernet adaptor with static dns servers does nothing.



My system:
Running on VMWare esxi4 with 1 network interface as 192.168.1.3
DNS 127.0.0.1, and then my DSL router 192.168.1.254
Gateway Broadband   192.168.1.254   eth0   1

So any help would be appreciated.
I'm still miffed though why VPN traffic is not routed to the server as default without changing files.
I mean - SBS doesnt require such changes and this is the real aim of zentyal.


Please help in any way you can...
