Sub-IP for Jail?

munificent · Jul 16, 2012

Hi guys,

Just slapped RC1 onto my home server and getting to grips with it. Seems terrific. One problem, though. The plugins jail needs a separate (virtual?) IP address. I picked one within my router's range and the system doesn't like it. Is there any particular method for selecting this sub-IP?

ProtoSD · Jul 16, 2012

Is it the same range as the IP address for FreeNAS? It can be one off from what your FreeNAS IP is.

munificent · Jul 16, 2012

It's in the same range, yes. Upper limit of that range to avoid my router giving the same IP to something else, but well within it. I'll try it one off from the FReeNAS itself and see how that goes

ProtoSD · Jul 16, 2012

Can you be more specific when you say the jail doesn't like it? Is there an error? What doesn't seem to work?

munificent · Jul 16, 2012

Nope. Changing the IP to one off from the IP of the FreeNAS itself didn't work. Could it be that I have not yet configured my mount points, and the system is getting muddled? I'm working on that now, but mount points are not straightforward for a Windows man like myself to understand.

Specific: I get an amber alert in the top right hand corner and this message:

WARNING: The plugins jail IP is not reachable, the plugins will malfunction.

munificent · Jul 16, 2012

I have now setup a mount point as follows:

/mnt/HeadNet/tank/unfiltered /mnt/HeadNet/Lockup/Prisoners/usr/pbi

That's going to be my 'requires attention' subfolder and the main path to my jail.

My router goes from *.*.*.63 - *.*.*.253. My first go at an IP was .150, then went to .70 (my FreeNAS is on .69).

Jail IP Netmask on /24 (255.255.255.0) both times.

That is pretty much every piece of configuration information I've done thus far.

Could Netmask be wrong? Mountpoint? Could it be my router that's to blame? I'm stumped!

ProtoSD · Jul 16, 2012

Its not your router or mountpoint, the netmask looks fine also.

Can you open a shell using the shell icon in the tree menu on the left, then type the following commands:

jexec 1 csh

ifconfig -a

Copy and paste the output of the ifconfig command and post it here. Add some code tags around the output

Since the bloody editing toolbar doesn't work here in the forums.

EDIT: I cant' type an example of the code tags but without the spaces: [ code ] [ /code]

I think I have a similar problem here. I've got my mount points correct. Now the networking is giving me fits. I cannot ping the jail ip from the rest of the network. I can ping the jail ip from the freenas shell and I can ping the reverse.

Config:
FreeNAS ip 10.0.0.3/24 dhcp reserved by mac at router
jail ip 10.0.0.7/24 static

This is from inside the jail:

Code:

This is from outside the jail:

munificent this will go smoother if you show us the actual IPs. In addition to what protosd asked for, run the following, outside the jail, as root from an SSH session:

Code:

ifconfig -a

netstat -rn

I've never had a problem. Though that's probably because I've never used it.

Right, I am closer to the problem, no closer to fixing it. I watched a YouTube video about mount points in 8.2 and I can see that my jail is not setup correctly at all. That is to say, when I type the

Code:

jls

command, there is no jail listed for me to go into and get the information from inside it that protosd requested. Since it looks like I made a mistake earlier in the process, let me list what I did:

1) In the Storage tab I created a ZFS dataset under HeadNet that I called Lockup, and gave it a 4g quota and reserve
2) I downloaded the PBI from this link: http://sourceforge.net/projects/fre...NAS-8.2.0-BETA4-x64.Plugins_Jail.pbi/download
NB - I didn't grab the sha256 file
3) I followed the jail setup in the GUI, allowing it to temporarily store the PBI on mnt/HeadNet as it wanted to. That got me as far as the IP settings screen (Step 2 of 3) where these problem began.

paleoN asked for the vanilla ifconfig output and it's as follows:

munificent · Jul 17, 2012

I replied with all the relevant code etc. It's awaiting mod approval. I think the mistake may have been further up the chain.

munificent · Jul 17, 2012

Right, I think I know what the problem was, and I am working my way towards fixing it. I had created 2 datasets, 1 for the jail, another for the plugins. BUT I had placed the plugin one *within* the jail dataset, which I believe was my error.

I deleted the attempted jail and the datasets and rebuilt them, this time with two separate datasets, not nested. I went through the process for creating the jail and first impressions are positive. The command

jls

Now reveals a jail there, whereas before I saw no number under the JID field.

As per ProtoSD's request, I see this:

Nope, still getting the IP can't be accessed error.

2) I downloaded the PBI from this link: http://sourceforge.net/projects/fre...NAS-8.2.0-BETA4-x64.Plugins_Jail.pbi/download

This link is for the BETA4 jail. What's more your networking output also appears to be from BETA4. You need the RC1 jail and to run RC1 itself.

If you have a second USB key, you should if you don't, do a fresh install of RC1 on it and go from there.

That's my mistake for linking to the wrong file. The file I downloaded was the RC1 jail pbi. The filename is FreeNAS-8.2.0-RC1-x64.Plugins_Jail.pbi. I do have a spare usb stick and could do a fresh install but I can assure you I'm running RC1 all the way. If I do a fresh install, surely I'll get the same errors, just on a different stick? I mean, I'm game to try it, but I was hoping there would be a user error visible somewhere that I could tweak and learn from.

I have the same error on my box - fresh install of RC1:
WARNING: The plugins jail IP is not reachable, the plugins will malfunction.

Are you using static IP?
Have you configured the default gateway under Network -> Global Conf?

If you didn't, stop the jail, configure it and then start it again...

my box is like this:

box with one networkcard re0 (static ip: 192.168.1.100/24; gateway 192.168.1.99)
this will go in a 5Ghz wireless router, that is like this static ip: 192.168.1.240/24 gateway 192.168.1.99 with LanNetwork from: 192.168.1.100 -199/24
on jail I put via GUI interface - 192.168.1.88/24. I still see that ip on config screen..
but on warning mess: not Ip for jail ..etc. The box will be used to play films via minidlna (this one doesn't start because of jail issue. I quess)
