I have a problem with LPR command:
/usr/ucb/lpr: printer1: unknown host localhost
ping printer1 → unknown host
ping IP_printer1 → OK
/etc/host config OK ( printer1)
what does /etc/printcap look like? “printer1” is defined in there. You need to find out what “rm” (remote machine) is pointing to and see if you can ping it.
The problem is with DNS, config in /etc/resolv.conf, in QNX6 is the same config ?
You can configure name services and if it will look in /etc/hosts first via phlip.
