Sure, Abhiram, the problem is very simple. You have to start the Trousers TCS Daemon, tcsd. It is usually in /usr/local/bin and must be run as root (actually you can set it up to run as a less privileged account but for testing this is easiest). Run it with the -f flag at first so it stays in the foreground and you can see any error messages it produces. So go into a separate window and run:
sudo /usr/local/bin/tcsd -f This usually prints a couple of error messages that don't mean anything, but hopefully it will start up and run. Then you can do tpm_version and other programs from tpm-tools. You don't have to run them with sudo, they should be run as normal users, just ./tpm_version and such. Let us know if you still have problems - Hal Finney On Fri, Oct 16, 2009 at 11:32 PM, Abhiram Kasina <[email protected]> wrote: > Hi Hal > > Thank you so much for the advice. I am looking into it.
