Can't access from my laptop

nocta · 2. Oktober 2017

Hi,
I'm using OMV 3.0.88.

I had no problem whatsoever the first installed OMV. A couple of days ago, I noticed that I wasn't abled to access via web to my admin page but my NFS shares were working just right. I tried with my cellphone and other laptop and the webgui was working.
I flushed iptables on OMV and on my Debian PC but didn't work. I reset my router (just in case) but didn't work either.

Now, I'm just like a couple of days ago. I can access using my cellphone and laptop but can't access from my primary laptop. I made a clean new install of Debian in my primary laptop and a new clean install of OMV on the NAS but I can't access via web nor via ssh.

I'd appreaciate your help.

Impossible to help you with the information you have provided. You're going to have to describe your network topology for all devices that work or don't work.

Sorry.

I have a TPLink router running ddwrt (v3.0-r33375), 2 laptops (1 wired laptop running now Ubuntu 17.04 x64; 1 wireless netbook running Windows 7 x32), and the NAS Server (Gigabyte E350N-USB3, 2GB RAM). And well, my cellphone wireless connected.
The only device that is not working is my Ubuntu laptop. I can't even access using ssh

Still inadequate information. You need to specify the network configuration for every machine including IP address, subnet mask, gateway IP address, and how the IP addresses are assigned (static or via DHCP).

Every single machine has its IP assigned via DHCP. No MAC address reservation whatsoever.
I tried using static IP but didn't work out either.

Router
WAN parameters via DHCP
LAN
Router IP: 192.168.1.1
Mask: 255.255.255.0
Gateway: assigned from WAN
DHCP range: 192.168.1.100 to 199.
DMZ is disabled. UPnP is enabled. I tried disabling UPnP but still.
I also tried changing the network parameters to 192.168.2.xxx and DHCP range from 192.168.2.100 to 199 but still nothing.

Example from Ubuntu's laptop
IP address: 192.168.1.117
Mask: 255.255.255.0
Gateway: 192.168.1.1
Broadcast: 192.168.1.255
DNS: 192.168.1.1

OMV:
IP address: 192.168.1.121
Mask: 255.255.255.0
Gateway: 192.168.1.1
Broadcast: 192.168.1.255
DNS: 192.168.1.1

When I try ssh from Ubuntu:

Code

ssh root@192.168.1.121
ssh: connect to host 192.168.1.121 port 22: No route to host

When I try webgui I get the regular Firefox offline website:

Code

Unable to connect


Firefox can’t establish a connection to the server at 192.168.1.121.


    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Well, still no information

I would try to ping and traceroute from here to there (at least wired laptop to router and OMV and vice versa) and see whether there's a pattern.

BTW: 'No route to host' is really that (and not filtered ports or stuff like that on the target machine), your Ubuntu machine has 'no route to host' 192.168.1.121 so either there's something wrong with ARP (unlikely after what you did already) or your router blocks access to this address for whatever reasons.

If the laptop that can't establish a connection would be the only wireless device I would check whether LAN / WLAN interconnection is allowed but in your case it's funnily also the only wired device that can not access the (wired?) OMV machine.

What does ifconfig say when run from the Ubuntu laptop's shell?

nocta · 3. Oktober 2017

It's been solved. It was the router running on DDWrt. I ran

Code

swconfig dev eth1 set enable_vlan 1
swconfig dev eth1 set apply

And problem solved.

Sorry for the disturbance and thanks for your inpunt.

Jetzt mitmachen!
