New ISP = New Router = Jail Not Found?

[ucrbuffalo]

I switched ISPs today and I'm working on getting my entire network moved over. I'm pretty close, except for one problem:
My old router was on 192.168.1.XXX, but the new router is 192.168.2.XXX. This is fine, and I haven't had an issue changing the IP in FreeNAS or on the Jail. However, the only jail I'm currently running is Plex, and after changing the IP, the Plex webGUI cannot find my PMS. I have tried restarting the jail, even restarting the box, to no avail. The router sees the jail and there's no issue there, as far as I can tell. The front end just doesn't want to connect for some reason.

Change the default route in your resolv.conf file in the jail to reflect the new default gateway.

Looking mine, only shows the nameserver. Where the change needs to be made? Add to it? Not on rc.conf?

Code:

root@plexmediaserver_1:/etc # cat /etc/resolv.conf
# Generated by resolvconf
search xxxxxxxx.com
nameserver 10.10.10.1

 

[Jailer]

Sorry, nameserver not default route. That's what I get for trying to work from memory.

After above changes ...

Assume the nameserver will play part on name resolution. When clicking the here on Click here to access your Plex Media Server!, I get the Plex IP address pointing to port 32400.

What do you see in as the link you will be directed to? Is it the IP the same you see in your router?

Drop to your shell (ssh or via gui), type:
jls

You will see:

JID IP Address Hostname Path
1 - plexmediaserver_1 /mnt/raid/jails/plexmediaserver_1


Get into your Plex by typing jexec <JID #> (jexec 1 in above case)

Check your IP:

root@plexmediaserver_1:/ # ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384

Check if you can ping outside:

root@plexmediaserver_1:/ # ping yahoo.com

Make sure all is correct for your network. Please note mine is 10.10.10.0/24, so above values will show that.

If using DHCP on FreeNAS and Jails/Plugins, changing routers should be transparent. If not I'd talk with the Devs :D

Wow. This is a great thread! One tiny can of worms for me though. Plex is identified as number 4. So I typed in "jexec 4" and it says "No such file or directory". Why is that?
Additionally, if I open the shell directly from the jail and try to ping, it cannot connect.

Is the plugin running?

Yes it is.

 

[nojohnny101]

If indeed the jail is number 4, did you try

Code:

jexec 4 tcsh

 

[melloa]

Did the above post is from the Plex plugin? I see an IP from the subnet you've indicated ... Did you change the nameserver as @Jailer suggested? What about results from
netstat -rn
Does it show your router's IP as default gateway?

 

[melloa]

Also ... on the associated jail for your plugin, does it show DHCP? Is the assigned IP correct? And the default gateway your router?

 

[ucrbuffalo]

This is what I see. However, I'm still trying to find the nameserver.

 

[melloa]

I see you are not using DHCP and your gateway is empty. Update IPV4 default gateway with your router's IP and try.

 

[ucrbuffalo]

No luck. The DHCP shouldn't be on since its a static IP, right?

 

[Jailer]

No luck. The DHCP shouldn't be on since its a static IP, right?

Correct.

To change the nameserver you need to open a shell for the jail and edit the resolv.conf file. It's located at /etc/resolv.conf.

 

[ucrbuffalo]

Well s***... I never mess with the shell except for really basic stuff so I'm not entirely sure how to do that. Off to the far reaches of the internet I go!!
(Or searching the forums, lol)

Putty is your friend.

 

[melloa]

Know the feeling.

You will probably have vi. Do a search on how to navigate and save the file with it. I use nano, but it is not installed by default.

The question still: If you changed the default gateway @ the jail configuration, why the resolv.conf has not be updated ...

 

[ucrbuffalo]

Putty is your friend.

Perhaps, but I've never used it before and now I'm going to be spending an hour and a half trying to learn....
