| Post subject: | ProblemFollowing Secure Communications with OpenVPN tutorial |
I am trying to set up an openvpn server on my linode but ran into a problem I can't figure out. In the "Initializing Public Key Infrastructure" section of the tutorial found here (https://library.linode.com/networking/o ... 04-precise) I see the command: Code: . /etc/openvpn/easy-rsa/2.0/vars I do that (as a regular user) and get the expected outcome. However, when I go to the next step Code: . /etc/openvpn/easy-rsa/2.0/clean-all I get unexpected outcome, I am told the script can not create the needed directory. If I run the command as: Code: sudo /etc/openvpn/easy-rsa/2.0/clean-all I am told I need to source the vars file first - seems like I had just done that! I am running as a regular user and so try with sudo - the error is that the "." is 'command not found'. What is that "." at the beginning of the line anyway? How do you get around it? thomas |

Hmmm, I seem to have solved the problem (though I am still mystified by the leading "." in the commands in the tutorial). Turns out I couldn't get this to do this by logging in as my normal user and then using sudo but if I did a switch user to the root user and issued the commands everything worked fine. Code: sudo su root Not sure what the difference is between being root and using sudo in this case ... other than one worked and one didn't! thomas |

The dot "." causes the shell to read and execute the commands in the named file. You ran into some problems because a sudo environment doesn't inherit all the settings of the invoking environment. You can run sudo su - to get a root shell, then execute your commands as root, and type exit to return to your original user. (Which is mostly what you did.) |

Vance, Thanks for the clear explanation. I have been using Linux for 8 or so years and had not run across that. thomas |
