Jail problems

I try to use jail first time.
When I begin to start jail in Nas4free server I find wiki page about it
I build my jail step-by-step as wiki, I replace IP only.
In first
script jail_start with error

#!/bin/tcsh -x
#mounting to /jail
mkdir /jail
mount_nullfs /mnt/jail /jail <------ Error here, must be for this building mount_nullfs /mnt/data/jail /jail
# copy jail binaries to /usr
cp -r /jail/conf/root/ /
# link config files to /etc
ln -s /jail/conf/rc.conf.local /etc
#start all jails
/etc/rc.d/jail start

My building
Host_for test - working machine x86-embedded on AMD Sempron(tm) 2200+ , 9.1.0.1 - Sandstorm (revision 262)
I add jail folder from another host over NFS, because I don't have space on my testing mashine. Jail folder mount to /mnt/data/jail.

My startup script

Code: Select all

#!/bin/tcsh -x
#mount nfs
mount -t nfs 10.0.0.1:/mnt/disk/freebsd/jail /mnt/data/jail
#mounting to /jail
mkdir /jail
mount_nullfs /mnt/data/jail /jail
# copy jail binaries to /usr
cp -r /jail/conf/root/ /
# link config files to /etc
ln -s /jail/conf/rc.conf.local /etc
#start all jails
/etc/rc.d/jail start

My problem: Jail started, but not have access to and from internet.
when I execute ifconfig, I don't see IP adress.

Code: Select all

 root@proto:/ # ifconfig
vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=82808<VLAN_MTU,WOL_UCAST,WOL_MAGIC,LINKSTATE>
        ether 00:11:5b:7f:29:cf
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
plip0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> metric 0 mtu 1500
ipfw0: flags=8801<UP,SIMPLEX,MULTICAST> metric 0 mtu 65536

        options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>


Also when I run #/etc/rc.d/jail start , nas4free answer is

Configuring jails:.
proto.domain.local.

Anybody can help me ?

Just reebot host 2-3 times.. It begin execute portsnap fetch update.

I can not create user for jail from command line.
Building says

Code: Select all

pwd_mkdb: flock: Operation not supported
pw: passwd file update: Inappropriate ioctl for device
adduser: ERROR: There was an error adding user (minecraft).

sorry no help for my side , only links to pages, perhaps helps you:

Thank you.
This is first my jail, I need study it. Also I help to attach minecraft server for peetbul.
Now I find error in nas4free wiki and one "not clean" work. I think, jail must be create into memory device:
1. create file for jail with dd comand and properly size, for example (for 9.5GB size)

Code: Select all

dd if=/dev/zero of=/path/to/jail/proto/image/jail.bin bs=1M count=10000

2. Attach it with mdconfig command

Code: Select all

mdconfig -a -t vnode -f /path/to/jail/proto/image/jail.bin -u 10

3. Format and label it.
4. Mount it and create jail inside a file.
===============
Now my success steps is - run jail, add port collection and sources, install Java into jail.

OK, I continue. I rebuilt nas4free test machine and replace x86-full on AMD Sempron(tm) 2200+ with 512M ram on x64-embedded on AMD E-350 with 2G ram.
But small trouble - I haven't hard disk, but I built new noob - idea.
I built two iSCSI target on my working FreeNAS 7.5 for /mnt/data partition and /jail for minecraft.



For this work, I create folder /cf/script and create 3 files
1. File /cf/script/startup.sh. This file I create as executable, and run is as postinit script

Code: Select all

#!/bin/bash
# Load iSCSI client
kldload /boot/kernel/iscsi_initiator.ko
# Add data disk to install packages on embedded version
iscontrol -c /cf/script/iscsi.conf -n idisk1
sleep 5
mkdir /mnt/data
mount /dev/da1p1 /mnt/data
mount_unionfs /mnt/data/opt/usr_local /usr/local
mount_unionfs /mnt/data/opt/var /var
iscontrol -c /cf/script/iscsi_jail.conf -n idisk1
sleep 5
mkdir /jail
mount /dev/da2p1 /jail
# copy jail binaries to /usr
cp -r /jail/conf/root/ /
# link config files to /etc
ln -s /jail/conf/rc.conf.local /etc
#start all jails
/etc/rc.d/jail start


2 File /cf/script/iscsi.conf

Code: Select all

idisk1 {
    authmethod      = NONE
    initiatorname   = iqn.2005-01.il.ac.huji.cs::nas4free.local
    TargetName      = iqn.2007-09.co.il.p.aganim:nas4free.data
    TargetAddress   = 10.0.0.1:3260,1
}

3. File /cf/script/iscsi_jail.conf

Code: Select all

idisk1 {
    authmethod      = NONE
    initiatorname   = iqn.2005-01.il.ac.huji.cs::nas4free.local
    TargetName      = iqn.2007-09.co.il.p.aganim:nas4free
    TargetAddress   = 10.0.0.1:3260,1
}

This building work, but minecraft not work under FReeBSD-9 if I use the base scheme for FreeNAS .
I continue..

Yes! It work

Ok, I try compile under jail BSDMC.
In first - processes under jail must be run from host root. If start process from proto root, files for word, compiled from source have flags unchange, and proto's root can't copy or remove its.

Code: Select all

chroot /jail/proto

...
But it not help me..
Log
