I am having trouble getting to a certain server/website online and also connecting to the server with ssh USERNAME@HOSTNAME. Am using a machine with Lubuntu 14.04. I can connect to the server from all other computers I have tried.

My main problem is that I can't get to any websites on the server in a web browser (using Firefox) - the ssh-ing isn't a problem, as I can do it using ssh USERNAME@IP-ADDRESS.

I have also seen that ping HOSTNAME renders the wrong IP-address, so I guess this could be a clue to what's wrong?

Some further info below, if it's useful. I'm new to working with servers and networking, so do say if there is other information needed to say what is wrong.

root@Elizabeth:/# nm-tool | grep "DNS"
DNS: 172.20.10.1
DNS: 172.20.10.1

root@Elizabeth:/# nslookup HOSTNAME
Server:        127.0.1.1
Address:    127.0.1.1#53

Non-authoritative answer:
Name:    HOSTNAME
Address: IP-address # correct IP-address for HOSTNAME

root@Elizabeth:/# ip route
default via 172.20.10.1 dev eth1  proto static 
172.20.10.0/28 dev eth1  proto kernel  scope link  src 172.20.10.3  metric 1 
172.20.10.0/28 dev wlan0  proto kernel  scope link  src 172.20.10.5  metric 9

(This question is similar to this one, but that question didn't focus on the browsing problem.)

  • What is “the server” and did you set it up yourself? What is 172.20.10.1? How namely looks an URL that doesn’t work, and where do you try to access it? – Incnis Mrsi Sep 12 '15 at 11:41
  • The server is set up by a university, ws1.bmc.uu.se, which I'm trying to access in Firefox. I'm afraid I don't know what 172.20.10.1 is. I just thought there could be something wrong with the DNS, so I though the output of nm-tool might perhaps help someone solve it. – Ingrid Sep 12 '15 at 11:47
  • For me, http://ws1.bmc.uu.se redirects to http://it.bmc.uu.se/webservice.php . Where is the problem?    By the way, ws1.bmc.uu.se has address 130.238.55.19   is it you? – Incnis Mrsi Sep 12 '15 at 11:50
  • So, I can get to http://it.bmc.uu.se/webservice.php (but am not directed there from http://ws1.bmc.uu.se). And I really want to get to a website under this domain name, where you need a special link with hash and id to get in (which I have, but still can't get there). Can't seem to get to anywhere on this domain name. – Ingrid Sep 12 '15 at 11:55
  • Do you try to access ws1.bmc.uu.se from the same LAN? It’s a known problem with cheap buggy routers or incompetent setup. – Incnis Mrsi Sep 12 '15 at 11:56
  • No, I'm on a different network. And 130.238.55.19 is the correct IP address of ws1.bmc.uu.se. But when I ping it I get a different IP address (130.238.39.248). – Ingrid Sep 12 '15 at 11:58
  • Oops, just understood what are you speaking about. Where exactly do you resolve ws1.bmc.uu.se as 130.238.39.248? How recently was the it added to bmc.uu.se? – Incnis Mrsi Sep 12 '15 at 12:04
  • In Lubuntu 14.04 terminal using ping ws1.bmc.uu.se. Don't understand the last quesion, sorry, am not so used to this. – Ingrid Sep 12 '15 at 12:05
  • Then your current workstation queries a buggy nameserver. Look what does /etc/resolv.conf contain and contact admins of that servers. Note that if domain record for ws1.bmc.uu.se was changed recently (within 24 hours), then it might be a transient phenomenon. – Incnis Mrsi Sep 12 '15 at 12:08

DNS at the workstation was sabotaged with: 

130.238.39.248  ws1.bmc.uu.se

in /etc/hosts.
