Unable to create new functional certificates for clients

[gcp900]

Hello everyone:

A couple months ago I configured an openvpn network with a raspberry pi as a server. Everything works fine, but now I want to create new certificates for new clients and I am having problems. When I create the certificates I do

Code: Select all

source ./vars

and then

Code: Select all

./build-key clientname

and everything goes well, but when I try to connect with that certificates the console gets stuck in this point

Code: Select all

I have removed information from these lines because it is a personal information, but the rest of the code is the same. After these lines of code if I wait I get this

And as you can see it gets restart in an endless loop. It is not a network connectivity problem because with the same computer and different certificates (the certificates I did the first time I configured the server) it connects without problems.

Where can it be the issue???

I am using linux the whole time for this.

Thanks!

Another thing. I touched this file

whichopensslcnf

before doing the certificates but then I left it as it was before. Anyway I am going to post the code to be sure there is nothing wrong inside.

Code: Select all

#!/bin/sh

cnf="$1/openssl.cnf"

if [ "$OPENSSL" ]; then
    if $OPENSSL version | grep -E "0\.9\.6[[:alnum:]]" > /dev/null; then
        cnf="$1/openssl-0.9.6.cnf"
    elif $OPENSSL version | grep -E "0\.9\.8[[:alnum:]]" > /dev/null; then
        cnf="$1/openssl-0.9.8.cnf"
    elif $OPENSSL version | grep -E "1\.0\.[[:digit:]][[:alnum:]]" > /dev/null; then
        cnf="$1/openssl-1.0.0.cnf"
    else
        cnf="$1/openssl.cnf"
    fi
fi

echo $cnf

if [ ! -r $cnf ]; then
    echo "**************************************************************" >&2
    echo "  No $cnf file could be found" >&2
    echo "  Further invocations will fail" >&2
    echo "**************************************************************" >&2
fi

exit 0

Thanks again
