# Install oracle InstantClient
|
|
|
|
|
|
InstantClient 10 is recommended to allow you to talk with 8,9,10,&11 server versions.
|
|
|
|
Go to <https://www.oracle.com/database/technologies/instant-client/downloads.html> and select the link corresponding to your UNIX PC's architecture. Example for Linux x64, use the Instant Client for Linux x86-64 link, which should take you to <https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html>
|
|
|
|
Grab these:
|
|
* Instant Client Package - Basic
|
|
* Instant Client Package - SDK (devel)
|
|
* Instant Client Package - SQL*Plus (not needed for Metasploit but useful to have)
|
|
|
|
unzip into /opt/oracle
|
|
```sh
|
|
cd /opt/oracle
|
|
unzip /opt/oracle/oracle-instantclient-basic-10.2.0.4-1.i386.zip
|
|
unzip /opt/oracle/oracle-instantclient-sqlplus-10.2.0.4-1.i386.zip
|
|
unzip /opt/oracle/oracle-instantclient-devel-10.2.0.4-1.i386.zip
|
|
```
|
|
|
|
Now set up a symlink so the gem installation can find the right lib:
|
|
```sh
|
|
ln -s libclntsh.so.10.1 libclntsh.so
|
|
```
|
|
# Set up your environment
|
|
|
|
You can either create .sh file to make the appropriate changes when you need it or just add it to your .bashrc
|
|
|
|
```sh
|
|
export PATH=$PATH:/opt/oracle/instantclient_10_2
|
|
export SQLPATH=/opt/oracle/instantclient_10_2
|
|
export TNS_ADMIN=/opt/oracle/instantclient_10_2
|
|
export LD_LIBRARY_PATH=/opt/oracle/instantclient_10_2
|
|
export ORACLE_HOME=/opt/oracle/instantclient_10_2
|
|
```
|
|
|
|
# Additional steps for Kali Linux
|
|
|
|
If you are using Kali Linux, you need to perform a couple of additional steps before the Oracle client gem will build properly. First, set your path to prefer the correct version of ruby so that Metasploit can use it:
|
|
```
|
|
root@kali:~/ruby-oci8-ruby-oci8-2.1.8# export PATH=/opt/metasploit/ruby/bin:$PATH
|
|
```
|
|
|
|
Next, install libgmp (needed to build the gem):
|
|
```
|
|
root@kali:~/ruby-oci8-ruby-oci8-2.1.8# apt-get install libgmp-dev

# Install the gem
|
|
|
|
Back in your Metasploit directory, copy `Gemfile.local.example` to `Gemfile.local`, then add the following line to the `:local` group
|
|
```ruby
|
|
gem 'ruby-oci8'
|
|
```
|
|
|
|
Update gems:
|
|
```sh
|
|
bundle --gemfile Gemfile.local
|
