svn over ssh tunnel

 

 

 

 

 

 

 

 

 

It is very often required that you need to commit/update to the svn repository which is only indirectly accessible through a gateway (user can ssh to gateway and gateway can ssh to internal svn server)

Suppose you have a working copy (locally on your machine)  setup with the real svn url (eg : svn+ssh://svn.example.com)

- Make ssh connection with local port forwarding to the gateway server

# sudo ssh gateway.example.com -L 22:svn.example.com:22

Change the repository url to localhost, since the local host connection forward to remote svn server through the gateway.

#cd <local_svn_path>

# svn switch --relocate svn+ssh://svn.example.com/trunk svn+ssh://localhost/trunk

Now you should be able to update, commit, etc to/from your repository.

You can switch it back to the original url when you have direct access to repository.

Install directadmin on Debian 6

Install the basic debian server without any server components

Install the dependency packages:

# sudo apt-get install gcc g++ make flex bison openssl libssl-dev perl perl-base perl-modules libperl-dev libaio1 libaio-dev bind9

Purchase and register the server ip at directadmin.com

Once the license is activated, login to the server:

$ wget http://www.directadmin.com/setup.sh

$ chmod 755 setup.sh

# sudo ./setup.sh

// enter the client id, license id, FQDN etc, and follow the instructions.

Once the installation completed the direct admin interface will be accessible at https://< server_ip >: 2222/

Racktable, Apache+LDAP authentication

Login to the Rack tables as admin:

Add the following line under configuration--> permission

allow {$tab_default}

* This is for read only account, assign extra permissions if required

Configure Apache + LDAP

< Directory /var/www/racktables >
Options +Indexes FollowSymLinks MultiViews
DirectoryIndex index.php
AuthName "Rack Tables"
AuthType Basic
AuthBasicProvider ldap
AuthzLDAPAuthoritative on
AuthLDAPURL "ldaps://ldaphost.com/dc=company,dc=com?uid?sub?(objectClass=< depends_on_ldap >)"



# Bind if required
AuthLDAPBindDN "uid=userid,ou=people,dc=company,dc=com"
AuthLDAPBindPassword "xxxxxx"
AuthLDAPGroupAttribute uniqueMember
AuthLDAPGroupAttributeIsDN on
require ldap-group cn=group_name,dc=company,dc=com
require ldap-attribute cn=group-name-allowed
< /Directory >

* Most of LDAP configs based on your setup

Configure Rack Tables:

Edit the inc/secret.php

Set :

$user_auth_src = 'httpd';
$require_local_account = FALSE;

NOTE: to get the logout working properly make sure the Apache AuthName matches with the one configured for Rack tables authentication.
