This is kinda cheating. But I found it to be very helpful and quick to install hamachi on elastix. First lets get into shell. mkdir /tmp/wget cd /tmp/wget "Were gonna steal some code from trixbox " wget http://yum.trixbox.org/centos/5/RPMS-2. ... 1.i386.rpm rpm -ivh hamachi-0.9.9.9.20-1.i386.rpm chmod 777 /usr/local/sbin/setup-hamachi setup-hamachi Now follow the prompts. B) If this tutorial helped you please pass on some good karma!
