Change in IP adress

Hello,

Recentley I had to change the internal IP-adress of my NAS from 192.168.0.100 to 192.168.2.100. Ever since apps (like sickbeard and coachpotato) are giving connection errors. I only changed the IP in the menu of the server, do I need to make changes in other locations aswell?

Ferdi

For example

[hpotato.core.plugins.base] Failed opening url in CouchPotatoApi: https://couchpota.to/api/search/jack+the/ Traceback (most recent call last):
File "/usr/share/cpserver/couchpotato/core/plugins/base.py", line 148, in urlopen
response = urllib2.urlopen(request, timeout = timeout)
URLError: <urlopen error [Errno -2] Name or service not known>

Re: Change in IP adress

Did you change the IP address of the gateway and dns servers?

Re: Change in IP adress

If you log in with ssh, and enter
# host lolo.sickbeard.com
# host couchpota.to

Do both resolve to IP addresses? (lolo.sickbeard.com should redirect to lolo.sickcache.com, which should give you 5 IP addresses).

If so, see if ping works:
# ping lolo.sickbeard.com
# ping couchpota.to


Was this change in IP address because you changed to a new internet provider? Are you still using the same LAN/WiFi setup - if not, what changes did you make?

These 2 steps.

Re: Change in IP adress

ok. It sounds like the sticking point is that you don't know how to log in with SSH. Is that correct?

Let's back up. Can you tell us why you needed to change the IP address in the first place?

Also, did you make any other changes in your network at that point? That is, a new router, or a new internet provider?

Re: Change in IP adress

Well I'm using WinSCP that's for SSH aswell right?

My change in ip-adress is because of a change from cable internet to internet using fibreglas. So I have a new router and had to change the internal ip-adress because of the set-up in the new router. New DHCP adress pool from 192.168.2.1 to 192.168.2.252. On my previous router the ip-adress of my NAS was 192.168.0.100, so I had to change it. Otherwise I couldn't get in to the NAS.

Re: Change in IP adress

WinSCP does both FTP and SSH. I use putty myself, so I am not clear the details of WinSCP.

If you are using SSH, then when you connect to the NAS you'd log in as root, but use your admin password. You'd only be able to connect if you've previously installed Netgear's enablerootssh add-on (which you can find here: http://www.readynas.com/?p=4203).

Once connected, you'd see a command line prompt, which ends with a # symbol. From there, you just type the commands above (omitting the #), and note the response.

I am thinking there is probably an issue with DNS, the "host" commands are checking for that.

Something else you could try: configure the NAS to use DHCP, and see if the behavior changes.

Re: Change in IP adress

# host lolo.sickbeard.com
# host couchpota.to


Both give connection timed out; no servers could be reached

# ping lolo.sickbeard.com
# ping couchpota.to


These 2 give: unknown host

Re: Change in IP adress

Ok.
Now try

host google.com
ping 108.160.155.153


If the ping works, it will repeat until you type ctrl-c

Did both host and ping again.

Host: connection timed out
Ping: 16 packets transmitted, 0 received

Re: Change in IP adress

ok.

Can you post the full ethernet configuration on the NAS? (gateway, IP, subnet mask, and DNS servers)?

also, did you try reconfiguring as DHCP?

Re: Change in IP adress

Try checking the gateway address and DNS server on your PC, and make sure it matches.

To do this
(a) click on the windows start button
(b) type "cmd" (without the quotes) in the "search programs and files" bar and press enter
(c) a command line window with a black background will open up. Click on it, and enter "ipconfig /all" at the prompt (again without the quotes). press enter

If you scroll through the info it gives you, you will find your PC ipv4 address, subnet, DNS server and gateway (with a lot of other stuff).

While there, try entering these ping commands and see if the PC gets a response:
ping lolo.sickbeard.com
ping couchpota.to
ping google.com
ping 108.160.155.153


BTW, who is your ISP, and what model router are you using?

Re: Change in IP adress

Ok.i think StephenB has helped you to find the problem.
Your PC and the NAS are on the same network using the same gateway yet you have set different gateways for each and different dns servers. This is why I asked you whether you had changed these in my first post.
The gateway cannot be 192.168.2.1 as you have stated that this is part of the dhcp pool.
The gateway address should be that of your device that is connected to the Internet or WAN. It looks like this is 192.168.2.254. The DNS servers addresses are there too, although you should be able to just enter ( in the readynas) your gateway address as the DNS server address.

After some testing with other adresses it seems to be working now.
