Hello, I have a curious situation using hamachi. Previously, I have used hamachi successfully. Recently, logmein hamachi have reported changes in their product but mostly account status and not technical AFAIK. Notwithstanding, attempts to create a shorewall interface with a dash in the name fails: Missing or Invalid Interface name. At the bash command line ifconfig dutifully returns the name of the virtual interface in question with status: up. I read all 7 or 8 GMANE references to hamachi but nothing that really helped. My question is a dash actually not OK for a virtual interface? I have attempted to use a dash '-' creating a shorewall network interface but this only evokes complaints from shorewall. Here is the single shorewall log as found from shorewall show log after invoking: service logmein-hamachi start.
