I'm tring to move an old SCO multi-user database on to RedHat7.2. I can start the db server OK and can start multiple user sessions from the console, but can't start a db session as a telnet user. Telnet itself seems OK, but when I try to access the db it exits complaining that the multi-user process does not allow piping or redirection of stdin or stdout.

Could this be due to some difference in the /dev device itself or even just the device name? - the old system has serial users as /dev/tty9a but telnet users get /dev/pts/9 - maybe the db server only recognises '/dev/tty...' as terminals?

Anyone know how I could get a telnet user to appear to the server as a '/dev/tty...'?
Any better ideas appreciated!

Thanks
Mike
