I really don't know. > What have you done to your system? Nothing special. I've never changed anything related to tty. Just in case, /etc/login.defs has TTYGROUP tty TTYPERM 0600 And I don't see anything else that could be related to the group of tty devices. I could find that someone else also found that the tty device was owned by "users" (before he changed it): https://bbs.archlinux.org/viewtopic.php?id=43982 So there seems to be some reason. Note that after some tests, it appears that "users" occurs only with mosh and GNU Screen, not for direct connections with ssh. But I can't reproduce "users" on other machines. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
