Hi, while looking into Cygwin's tty code, I stumbled over this problem: Every time you log in to Cygwin via sshd, the pty's permissions are set like this: $ ls -l `tty` crw--w--w- 1 user group 136, 2 Aug 27 13:06 /dev/pty2 Since Cygwin sets the permissions more tight to begin with, I was wondering why the permissions are this open. Turns out, sshd sets them like this:

...d_seedfile): Likewise. * serverloop.c (server_loop, server_loop2): Likewise. * session.c (session_dump, session_by_pid, session_exit_message, session_close_by_pid, session_have_children, session_close_by_channel): Likewise. * ssh-agent.c, sshd.c (main): Likewise. * sshpty.c (pty_setowner): Likewise. * uidswap.c: (temporarily_use_uid): Likewise. =================================================================== RCS file: authfile.c,v retrieving revision 2.9.9.2 retrieving revision 2.9.9.2.0.1 diff -pu -r2.9.9.2 -r2.9.9.2.0.1 --- authfile.c 2001/09/23 13:53:22 2.9.9.2 +++ authfile...

...Component: sshd AssignedTo: openssh-unix-dev at mindrot.org ReportedBy: idallen at freenet.carleton.ca I have to run a private copy of sshd (on AIX) as non-root because the local admin won't install the real thing. As non-root, I can't chown() ptys. The sshd function pty_setowner() fails and so does sshd when I try an interactive (shell) login. The chown() should not be attempted if sshd is running as non-root. (All the occurrences of chown() in sshpty.c need this checking.) ------- You are receiving this mail because: ------- You are the assignee for the bug, or are wa...

...magine this is not the right way to do it. I predict this breaks badly when the unprivileged process is chroot'ed. I think a better approach would be to switch to the actual user somewhere inside pty_allocate(). If we would call openpty() by the proper user, we wouldn't need functions like pty_setowner(), because openpty() already sets the proper permissions then. There's no rush in implementing this, but I think it would be cool if OpenSSH would honour this behaviour.

Could all those who were having problems with utmp logging on Solaris please try the test release at: http://violet.ibs.com.au/openssh/files/test/openssh-TEST-2000053100.tar.gz Users on other platforms, particularly HP/UX, AIX and SCO are invited as well, to test compatibility. The login code is heaps cleaner now. -d -- | "Bombay is 250ms from New York in the new world order" -
