If you run the application as root, you could create a device node that is identical to the real device as /dev/tty01 (since Linux uses /dev/tty1 they will not clash). This can only work if you understand how the application is constructing /dev/tty01 (I am sure this is not hardcoded, because that would not even work on SCO). > The developper is no more active and I don't have the sources. > One of my last resource is to find a way to start a terminal and have Centos > allowing me to start the application on a terminal as tty instead of a > pseudo-terminal. Even on SCO the application needs to figure out its own tty. So there should be a way to influence its decision. I don't even understand why it would go with /dev/tty01 over an SSH connection, unless it is hardcoded as a silly fallback default if all other measures have failed. Finding what these other measures are, may be the source of a solution ? >> (Or simply log on to the console instead of using SSH ?) > This haven't been tried, and I will to morrow; but our best will be to use > it a text terminal. You can also tru using 'conspy' to take over the real /dev/tty1 from an SSH or screen session and then start the SCO application. However if the SCO application expects /dev/tty01 then that would fail similarly. Creating a device node identical to the current tty is probably the best way forward if it really is /dev/tty01. You can do this simply by doing: cp -aLv /proc/self/fd/0 /dev/tty01 or maybe a symlink would work as well: cp -av /proc/self/fd/0 /dev/tty01 The advantage if a symlink is simply that you have a visual confirmation to what tty it is linking without having to decipher the major and minor device numbers. >> Not sure what your application is doing to, try stracing it to find out. > There is no possibility to trace at start-up. Man, aren't you glad that your SCO days are (almost?)
