retitle 59439 [DOC] [CHRISTIAN] login.defs: TTYPERM description and default are inconsistent tags 59439 confirmed thanks
Ben Collins answer to #59439 seems to make sense to me. I tested all this and, with the default setting of TTYPERM 0600 we have in Debian, users cannot use write to another user unless that user issues "dmesg y" in his/her terminal. This is a secure default which shouldn't probably be changed. So, the only concernis maybe adding some more comments to /etc/login.defs: # In Debian /usr/bin/bsd-write or similar programs are setgid tty # However, the default and recommended value for TTYPERM is still 0600 # to not allow anyone to write to anyone else console or terminal # Users can overwrite this setting by using the "dmesg y" command Colin, does it sound OK for you and enough to fix this bug�? --
