IRCNow

First make sure to set quotas

Second, make sure to change file permissions for

/home/username

We symlinked /htdocs inside each user's home folder to /var/www/htdocs/<username>

We installed

Inside /etc/httpd.conf:

        location "/~username/*" {
                root "/htdocs/username"
                request strip 1
        }

Update: hiding logs was causing problems

We also hide logs in /var/logs and /var/www/logs

To set the user's default prompt to “username$ ”, stick this into /etc/profile:

export PS1="`whoami`$ "
             # chmod -R o-rx /var/log
             # chmod o-rx /var/run/utmp
             # chmod o-r /var/log/wtmp*

Seems like there is no way to hide processes from users:

http://openbsd-archive.7691.n7.nabble.com/KERNEL-PATCH-add-process-hiding-fixed-td309339.html

# chmod 750 /var/www/logs/
# chmod 640 /var/www/logs/*
# chmod 750 /var/log
# chmod o-rx /var/log/*
# chmod -R o-rx /etc/mail

to turn accounting on.. only users love making use of it too

add login.conf rules

For each new user:

# adduser
# chmod 700 /home/username /home/username/.ssh
# chmod 600 /home/username/{.Xdefaults,.cshrc,.cvsrc,.login,.mailrc,.profile}
# mkdir /var/www/htdocs/username
# ln -s /var/www/htdocs/username /home/username/htdocs
# chown username:username /var/www/htdocs/username /home/username/htdocs
# edquota username

In /etc/httpd.conf:

        location "/~username/*" {
                root "/htdocs/username"
                request strip 1 
        }

In nsd zone files, create 1 subdomain per user so users get: username.shell.ircnow.org

any new suid binary's with

             # find / -perm -4000

Check /etc/groups to make sure that no user is a member of wheel. This will prevent them from su to root even if they know the password.

In /etc/ssh/sshd_config, turn off X11 forwarding

Create symlinks for users so they don't complain:

ln -s /usr/local/bin/tclsh8.6 /usr/local/bin/tclsh
ln -s /usr/local/bin/python3.7 /usr/local/bin/python

You will want to have /var/www/etc/resolv.conf to allow DNS lookup inside the chroot:

# mkdir /var/www/etc/
# cp /etc/resolv.conf /var/www/etc/
# chown -R www:daemon /var/www/etc
