Greetings. I have few jails running nginx on my FreeBSD 13.1 host. I'd like to create another jail for their SQL database needs. I'd like to create ZFS dataset for this purpose (for MySQL jail) but should I create it on host? If the dataset is created within the host, could the Jail access it...

Setting it to anything other than the default value disables all restrictions. Any idea why? Am I doing it wrong perhaps? { // devfs_ruleset=(rule number); mount.devfs; // }

/etc/jails.conf: firefox { path = "/root/jails/firefox"; ip4.addr = "10.0.0.201"; host.hostname = "firefox"; interface = "wlan0"; mount.devfs; allow.raw_sockets; exec.clean; exec.start = "/bin/sh /etc/rc"; exec.stop = "/bin/sh /etc/rc.shutdown"; } /root/jails/firefox/etc/resolv.conf...

Allowing non-root execution of a jailed application Jailed programs can generally be executed by using jexec(8). However, you have to be root in order to do that. In this short article I present an approach on how you can allow a specific set of non-privileged users to execute a particular...

Introduction and motivation There are great articles ([1] and [2]) by patovm04 here on the forum explaining how to run Chrome and Brave in a Linux chroot environment (usually /compat/linux or /compat/ubuntu). These approaches work great. However, I am a big fan of FreeBSD's jails and it has...

Hello, I'm not a FreeBSD newb, but I'm new to jails, and read different solutions. I tried to build a jail with a webserver. Now I could start it. Then I wonder that are different outputs with these commands after I had start it: jexec 57 ps -ax gives me something like this PID TT STAT...

Hello folks, yesterday I wrote a Twitter thread to give an example how to deploy VNET jails in a ZFS environment. Here is it again in this forum. A guide to deploy a VNET jail using a FreeBSD 13.0 server with ZFS and populated /usr/src. We start with preparing the file tree. I use /l/prison...
