I occasionally get the above message using pg. When it occurs, it persists until I log out and back in. Unix 2.01 on a 32/400. Any one know what causes this? -- John Alsop Sea Change Corporation 1100 Central Parkway W., Suite 38 Mississauga, Ontario, Canada L5C 4E5 Tel: 416-272-3881 Fax: 416-272-1555 UUCP: ...!uunet!attcan!darkover!seachg!jalsop

For some reason there is no controlling terminal is not associated with your session (process group). This should not happen suddenly but should be the case throughout a session. -- -Mike Wescott mike.wescott@ncrcae.Columbia.NCR.COM

This means that there is no controlling terminal for that particular process group (login session). Do you run any programs that play games with the process group? Or is this happening only on the console? Are there messages from init(1m) on the console as well? Are there other programs opening up your tty? -- -Mike Wescott mike.wescott@ncrcae.Columbia.NCR.COM
