How to install telnet service

July 18, 2008 at 5:55 pm · Filed under ubuntu ·Tagged

TELNET is a client-server protocol, based on a reliable connection-oriented transport. Typically this protocol used to establish a connection to TCP port 23, where a getty-equivalent program (telnetd) is listening, although TELNET predates TCP/IP and was originally run on NCP.

Install telnetd server
$ sudo apt-get install telnetd

Restart inetd service:
$ sudo /etc/init.d/openbsd-inetd restart

You should now be able to telnet to the server from Windows or Linux desktop system to Ubuntu Linux telnet server. Type the following command to connect to
Telnet server:

$ telnet ubuntu-linux-server-ip
$ telnet 192.168.1.200
$ telnet ubuntu.domain.com

Subversion with web access on ubuntu

May 25, 2008 at 7:26 pm · Filed under subversion, ubuntu ·Tagged , ,

I will take you through on how to install subversion with web access using apache module, which can be achieved through simple steps.

Installing subversion

sudo apt-get install subversion libapache2-svn

Creating repository

sudo svnadmin create /svnrepo

Editing web module configuration

I have used gedit for editing. You can use any editor of your choice

sudo gedit /etc/apache2/mods-enabled/dav_svn.conf

The Element in the configuration file indicates the root directory where the subversion will be accessible from. For example, if you are accessing the subversion as http://localhost/svn, the Location element will look like this.

<Location /svn>

Uncomment the DAV line to enable webdav module

# Uncomment this to enable the repository,DAV svn

Set the SVNPath line to the repository directory which you created in the beginning.

SVNPath /svnrepo

The next section is the Authentication to access subversion. This is just a basic authentication, so it is not considered to be very secure. Uncomment the following lines and leave it unchanged.

# Uncomment the following 3 lines to enable Basic AuthenticationAuthType BasicAuthName "Subversion Repository"AuthUserFile /etc/apache2/dav_svn.passwd

Create Users

c – creates new user.
m – md5 encryption

sudo htpasswd -cm /etc/apache2/dav_svn.passwdNew password:Re-type new password:Adding password for user

Adding permissions to repository

sudo chown -R www-data:www-data /svnrepo

Restart Apache

To reflect the changes made, restart the apache sever using the following command.

sudo /etc/init.d/apache2 restart

Access the url

Now access the url, you must be now able to browse the subversion repository.

http://localhost/svn
