A known quirk of sshd in other distros is that sshd will refuse to write to world- or group-readable /var/log/btmp. The fix for this is 'chmod 0600 /var/log/btmp'.
Ubuntu Linux installs /var/log/btmp with permissions 0660 (aka -rw- rw----). I already changed permissions to 0600 (aka -rw-------) and /var/log/btmp is still unaffected by bad login attempts via sshd. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/743858 Title: sshd not appending to /var/log/btmp -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
