Hi, I've got another hostid question, but this time it's a different problem. We have a piece of software which uses the value returned by hostid in generation of the license key. Last time I mentioned this, there was some discussion about the merits (or otherwise) of this approach, but leaving those arguments aside, the software does it this way, so I have to live with it ;-) My past problem was solved with the help of the list by modifying the /etc/hosts file and putting the hostname on a line with its correct IP, rather than the default setting, which had it on the same line as localhost (127.0.0.1). This meant hostid returned a 'proper' and unique value for the license key generation. Anyway...I've just run up two more Opteron machines, using FC3 for x86_64 and have edited the hosts file as before. Now, if I run hostid, I get unique values, however they look very different to those on any of my other machines (a mix of Rh 7, 9, FC2 and FC3 on i386 and x86_64). The latest lot have the form: ffffffff809d3f8e, whereas previous ones were like: 809d288e Looks like the last part of the number is correct, but what about all those leading f's ? My question is, are these normal, valid values ? If not, any idea what could be causing this ? Thanks, Andrew
