Hello, on 9.1-R, I highly appreciate the new jail(8) and jail.conf capabilities. Thanks for that extension! But I have one problem: If I want to stop a jail with 'jaill -r jailname', I get "umount: unmount of /.jail.jailname failed: Device busy" It seems to me that the order of fstab.jailname entries are not reverted by jail(8)...

Hi *, I recently triggered an error when setting up a jail-host: I configured the jail(s) like evry jail I set up in the past: On the jail-hosts /etc/rc.conf: # ---- Jail-Globals ---- jail_enable="YES" # Set to NO to disable starting of any jails jail_list="ftp mx1 relay" # Space separated list of n...

Hi, Running: Freebsd 6.0 I am wondering if it is possible to have acces to loopback ip in a jail. I currently have a server running a jail. In the jail, there is a database and a web server. I would like to be able to have the database only bind on a loopback address and not on the jail's ip. Can this be done and how? Thanks -Cyril _________________________________________...

I'm thinking of using jails to improve security on a server I am setting up. Specifically, I would like to put Apache/PHP in a jail, but I might like to set up 2-3 different jails for different purposes. I've found several examples showing how to set the jails up. My questions involve system requirements. Assuming...

I read this (http://www.petur.eu/blog/?p=459) blog post today. It's about that a remote user with root privilegs to a FreeBSD jail & user privileges to the jails host machine can obtain root privileges on the host machine. Can someone confirm if this bugg/exploit works?

I'm setting up a server where I plan to use Jails to improve security I also have installed and am configuring ipfilter. Here are my questions: Because I'm using Jails, I will have to have multiple ip aliases on the network interface. I will use ipfilter to specify what can go to each of the addresses. (e.g., allow only incoming to port...

HI everyone, I have resently installed a jail environment on my freebsd box, and had some problems getting postgresql running under it. After looking a bit on various mailinglists i figured out that I needed to set jail.sysvipc_allowed to be 1 using sysctl in order to make postgresql run. However man jail gives me: jail.sysvipc_allowed...

Hello, while playing with new jail features, I recognized that manually umounting doesn't work as I'd expect. After jail has been destroyed, the following mountpoint is active: /dev/gpt/jailname1ROOT on /.jail.jailname1 (ufs, local, read-only) There was var mounted to /.jail.jailname1/var but that sucessfully umounted....

Hi, i've got this problem with my jail and i'm abolutly lost as in the why of it. I previously posted this on comp.unix.bsd.freebsd.misc but i was advised to send here I was unable to find help on google :( To resume quick, when i'm in a jail, netstat doesn't work properly. Hopefully i have provided sufficient information f...

Hi, i've set the outside ip for the jail..It works.. When i try to ssh to jail'ed system from the main system (in which is created jail) the connection is successful, but when i try to connect to jailed system from anywhere else i get this message: ssh: connect to host IP_NUMBER port 22: Operation timed out What can be wrong here? How...

Hi, I attach 2 files in this email, the first is a Makefile and the second is jail.conf. For demonstre my idea i resolved create one "Pseudo Prototyping", for test is necessary: 1 - Create dir /usr/local/basejail 2 - Copy Makefile to /usr/local/basejail 3 - Copy jail.conf to /etc 4 - The initial basejail is precompiled is distributed in CD1, for simular basejail is n...

..., marked with a *) and gdb that to work out what > is the matter with it, and perhaps why it is in that situation. Hmm... I have no lslocks on FreeBSD; will lsof do?

Hello, I would like to run other services like messaging services on my firewall machine too. Does it make sense to run shorewall, openvpn and the pppoe package in a chroot jail? And is it possible to run these programs as an other user? Ciao Hugo

Hi all, Is it mandatory to add device mem to jails to enable network via the gateway? Left ezjail with FreeBSD-6.3 (and a hardware replacement of my server) and am now starting again with FreeBSD-7.1. Early this week, I upgraded from 7.0 to 7.1 (not having 'used' jails on 7.0). After creating the jail with `ezjail-admin update -i` I cr...

This message was sent to bugtraq today: While playing around with FreeBSD 5.4 and jailing I discovered that it was possible to put an ethernet interface into promiscious mode from within the jailed environment, allowing a packetsniffer to gather data not meant for the jailed box. This also affects FreeBSD 5.3 (tested) but not FreeBSD 4.x This can be reproduced on boxes where BPF sup...
