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 80 on the jail running apache). Another

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?

Hello, I'm wondering about closing some information leaks in FreeBSD jails from the "outside world". Not that critical (depends on the application), but a simple user, with restricted devfs in the jail (devfsrules_jail for example from /etc/defaults/devfs.rules) can figure out the following: - network interfaces related data, via ifconfig, which contains everything, but the

Although RAW sockets can be used when specifying the source address of packets (defeating one of the aspects of the jail) some people may find it usefull to use utilities like ping(8) or traceroute(8) from inside jails. Enclosed is a patch I have written which gives you the option of allowing prison-root to create raw sockets inside the prison, so

Howdy! I'm not sure if this is actually an issue, feature or a bug, but I have found that inside a jail, the jailed root user is able to sniff traffic (and enable promiscuous mode) on at least the interface of the IP address the jail is attached to. I have not found any documentation explaining if this should occur or not, but I feel it is something that should at least be known to those

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 plenty of disk space, 1GB ram and a dual processor PIII 1.13Ghz

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 This MIB entry determines whether or not

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

FreeBSD-12.1p7 Samab-4.10.15 running in FreeBSD Jail I just wish to ensure that my conclusion respecting Samba, FreeBSD Jails, and NTP is correct. 1. Unless configured otherwise Windows domain clients will query and obtain their time from the samba_server DC. 2. Samba_server obtains its time from the OS, in this case a FreeBSD Jail. 3. FreeBSD Jails get their time from their host. 4. If

I've got a server running FreeBSD 6.2 and PF. The server has a couple dozen jails on it. Previously, I had a few "private" services such as MySQL running on loopback IPs (127.0.0.2+) and the rest of the jails running on the public IPs. I have to renumber my machine with a new block of public IPs so I thought I'd be clever and move all the jails onto loopback IPs. Then

Hello all, I've been searching around and have come up with no current discussions on this issue. I'll keep it brief: In 7.0 or 7.1 is there any provision to have multiple IP addresses in a jail? I'm stumped on this, as I just started a new hosting project that needs a few jails. At least one of those requires multiple IPs, which is something I never really even realized was

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 to solve this problem?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear dovecot developers, first: thanks for this really cool imapd, on my server it serves some hundred domains, all in all some thousand users, some having hundred thousand mails in their Maildirs (their spam boxes mostly).

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) when shutting down/umounting.

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 names of jails

[Sorry about "top posting": my OT question arises from the subject..] Could someone elaborate on the "jail" under CentOS. I'm used to FreeBSD jails, and as I run CentOS and some other Linuxes for quite some time I was under impression that there is no such thing as jail under Linux [at least those flavors I run]. Under Linux I did use in variety of places chrooted
