Is anyone running tcx as a user other than root? I find that if normal
users try to run a tcx'ed executable, it fails with a Permission denied
error. The untcx daemon starts up, and runs setuid as expected, but the
untcx process which is invoked uncompress the executable seems to be
ignoring the setuid bit.
Now, untcx is invoked by having the compressed executable start with:
#! /usr/local/bin/untcx
Does 386BSD honour the setuid status of the *script* rather than the program
it invokes when executing such a file? This would explain the behaviour.
If so, can anyone suggest a workaround? Would getting untcx to re-exec
itself if its was not running as root solve the problem (if indeed this is
the problem)?
Mark.
