Hi,
I just saw the "TCSD crashing" thread, and the tcsd on my computer crashed too.
It used to work well, but I don't know why now it exits as soon as I run
"sudo tcsd".
I use netstat to check the port, and it is not used.
And I try strace to see if /dev/tpm0 is opened, and it is.
Any idea on what could cause tcsd to crash?
Here is the message of strace.
~ sudo strace tcsd -f
