Git Inside Jailed Environment
Obviously, the server must have Git installed:
sudo apt-get update ; sudo apt-get install git
We must add Git as a possible command for chroot-ed shell users.
If we have ISPConfig control panel, we can do that for all the future shell users by setting - appending /usr/bin/git to the field
Server Config -> Jailkit -> Jailkit chrooted applications.
That proved to be enough only for basic operation of cloning, and only under git:// protocol.
Note: Please note that adding Jailkit chrooted applications in ISPConfig must be done prior to creating first Jailkit user for a website. If you
want to copy files into a jail later, use the jailkit jk_cp command.
Warning: If you want a valid SSH user in ISPConfig, you must generate any password even if you don’t use one and login only with key authentication. So please, always specify password.
Problems & solutions
warning: templates not found /usr/share/git-core/templates
Just creating empty file will do:
mkdir -p $HOME/usr/share/git-core/templates
touch $HOME/usr/share/git-core/templates/description
And execute this to append to ~/.bashrc file:
cat << EOF >> ~/.bashrc
# fix Git warning
export GIT_TEMPLATE_DIR=$HOME/usr/share/git-core/templates
EOF
or type git every time with switch --template like this:
git clone --template=$HOME/usr/share/git-core/templates
This solution is valid and most minimalistic. But below is more elegant
and faster jk_cp solution.
fatal: Unable to find remote helper for ‘https’
We can avoid this error by using different protocol.
Happens on cloning:
git clone https://github.com/example.git
Simplest solution is to use git:// transport instead of https:// and
that will solve the problem. You can also use ssh:// transport, but
then you have to setup authentication keys.
Not sure really, but I think that on server I must have this libraries installed:
sudo apt-get install libcurl4-openssl-dev
fatal: Problem with the SSL CA cert (path? access rights?)
The complete error is:
fatal: unable to access 'https://...': Problem with the SSL CA cert (path? access rights?)
To permanently fix this, just type as jailed user:
git config --global http.sslverify false
If you want just temporary fix, one of the ways is this:
export GIT_SSL_NO_VERIFY=true

The best setup
First, you need to find out the jail for ssh user. The jail is your jailed directory (/var/www/clients/client0/web5).
How we can detect it? Well, on ISPConfig, if you log in as jailed user, you can read it with jk_list command on other console as root.
JAILDIR=/var/www/clients/client0/web2
jk_cp -v -j $JAILDIR /usr/bin/git*
jk_cp -j $JAILDIR /usr/lib/git-core/*
jk_cp -j $JAILDIR /usr/bin/ssh-keygen
jk_cp -j $JAILDIR /bin/uname
jk_cp -j $JAILDIR /usr/share/git-core
# Also add the curl command
jk_cp -j $JAILDIR /usr/bin/curl
I added the last one so we don’t need manually to fix templates not found warning.
We can also add curl or any other command with:
jk_cp -j $JAILDIR /usr/bin/curl
This will copy not only command, but all the dependencies of that command. Great!

MySQL dump inside Jail
Jailkit und mysqld.sock FIX*** | Howtoforge - Linux Howtos und Tutorials
Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’
Must be connected via TCP, and to force that, we can do this:
cat <<'EOF' > ~/.my.cnf
[client]
protocol=TCP
EOF
[client] user=mysqluser password=mysqlpass

Java inside Jailkit
JAILDIR=/var/www/clients/client0/web1
jk_cp -j $JAILDIR /usr/bin/java jk_cp -j $JAILDIR /usr/lib/jvm/default-java jk_cp -j $JAILDIR /usr/lib/jvm/default-java
paths = /usr/lib/jdk1.6.0_22/bin/java, /lib/libpthread.so.0, /lib/libdl.so.2, /lib/libc.so.6, /usr/lib/jdk1.6.0_22/jre/lib, /lib/libm.so.6, /lib/libm-2.5.so, /proc/meminfo
As that user:
nano ~/.bash_profile
export JAVA_HOME=/usr/lib/jvm/default-java
export PATH=$PATH:$JAVA_HOME/bin
export LD_LIBRARY_PATH=/usr/lib/jvm/default-java/jre/lib/amd64/jli/
Must relogin to test this: echo $JAVA_HOME
Ali mora prvo ono da se isključi - ISPConfig’s folder protection.
chattr -i $JAILDIR
mkdir $JAILDIR/proc
chattr +i $JAILDIR
And then:
mount --bind /proc $JAILDIR/proc
