This document is a quick overview of FreeBSD Jails at the ASF. Intended for PMCs with some notes for infra folk too. It is incomplete, please email users@infra with any queries you might have and to therefore help us complete this document.
Note that virtual machines are also available for operating systems other than FreeBSD. We don't seem to have documentation on those so far but as an example INFRA-4515 should provide enough info about how to get and use such a VM.
Here are some notes to assist the PMCs to manage their jail.
Your PMC chair is root of your jail, and can add other users.
Note: When creating accounts, please reuse username and userid from people.a.o
$ sudo pw user add <username> -u $uid -m -d /home/<username> -s /bin/bash $ sudo passwd <username>
Important: All accounts MUST log in using a public/private (RSA or DSA) key pair, see below. Users must add their keys to svn
https://svn.apache.org/repos/infra/infrastructure/trunk/ssh_keys/people/ so that zone admins can copy them after checking
that a key belongs to the corresponding user.
The standard process for this is
Username/userid must match LDAP
User must be in the
sshusers group, check with the
id command on the VM
SSH public key must be added to id.apache.org. Can be checked with
ldapsearch -xLLL uid=<username> sshPublicKey on people.apache.org for example.
On some VMs, SSH public key must be copied to
/etc/ssh/ssh_keys - check that folder to see if your VM is setup in that way, and if it's the case the
/root/bin/asf-sshkeys.sh script might be useful.
If SSH public key is ok and user gets an
access denied for this host error, ask infra to grant them access.
To check the SSH key of the VM use
/usr/local/bin/ssh-keyscan <VM hostname> on people.apache.org.
You can use
zsh -c 'ssh-keygen -lf =(ssh-keygen devicemap-vm.apache.org)' to get the fingerprint only.
Password must be changed (and OPIE set up, see below) at first login
Note: This section is not specific to jails, it applies to other machines accesses (eg, Ubuntu VM's) too. Ubuntu VM's use 'ortpasswd' (part of Orthrus) instead of 'opiepasswd'.
All users in the wheel group have sudo access. In order to use sudo, a user must configure OPIE by running 'opiepasswd' on the jail.
Using OPIE requires having an OPIE (S/Key) client on the local (trusted) machine. Some OPIE clients are:
SkeyCalc (Mac OS X)
Orthrus (Unix-like; portable)
FreeBSD: opiekey(1) is part of the base system
At a high level the process is this:
The Apache Installation can be found at /usr/local/etc/apache22/. The main
data directory where you can publish any results/documentation/etc is
located at /usr/local/www/apache22/data. The Apache instance can be controlled
with the /usr/local/etc/rc.d/apache22 script (sudo access required)
and the 'apache22_enable'
Java - either OpenJDK and/or Oracles Sun JDK have been installed on some of the jails. See /usr/local/bin/java. If 'java -version' or 'which java' comes up empty ask users@infra to install it for you or see the documentation if you fancy doing the license fetch/agree/install dance yourself.
See svn for extensive documentation
/etc/puppet exist on the VM?
