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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/743858 Title: sshd not appending to /var/log/btmp -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
