Status: Unverified
SYMPTOM(s):
ABL program calls out to UNIX
The call out to UNIX invokes the "su" command
Log files show "STTY : not a typewriter" error message
FACT(s) (Environment):
Progress 9.x
OpenEdge 10.x
UNIX
CAUSE:
When the "su" command is invoked from a shell it automatically runs all standard login scripts (.profile, etc). If any of the standard login scripts attempts to invoke a command which assumes a terminal is in use (i.e. STTY) and there is no terminal because the "su" command is being invoked from within a Progress session then the "not a typewriter" error will be displayed by the underlying UNIX operating system. The error message has nothing to do with Progress.
FIX:
All standard login scripts must be modified to check and see if the login is from a true terminal or not and if not, the script must not issue any commands which assume a terminal (i.e. STTY).
