[Planetlab-devel] myplc stuck at 'PLC: Generating SSL certificates for: PLC: WWW:' and does not continue

Hi Stephen,

The XML generator should check if stdout is connected to a terminal
before generating any ANSI formatting instructions. On Linux one might
do this by looking at the symbolic link /dev/fd/1.

E.g. try
ls -l /dev/fd/1

then
ls -l /dev/fd/1 > /tmp/foo

If you strace the program, then you might get some insight into why it
thinks stdout is a terminal.

I'm not sure of why its behavior changed with this build, though.

Sapan
