Received "malformed from address" from Unix
When trying to print from INTELLIscribe to Linux, the Linux LPD rejects the request and logs an error stating:
/usr/sbin/lpd: Malformed from address
The message also appears in the Properties dialog in INTELLIscribe.
The new version of INTELLIscribe sends data on source ports greater than 1024. This is to circumvent a problem with Windows and port timeout periods. Some flavors of Unix and Linux, by default, will only accept data on source ports less than 1024. This is due to a security hole present in systems providing both FTP and LPR/LPD functionality.
INTELLIscribe may be modified to send data on ports less than 1024 in the virtual printer port wizard.
- From the Printers menu, choose Add or update virtual printer port.
- Click "Next" until the final step.
- Modify the "Relax port restr" parameter to display "no" by choosing this from the drop-down list.
