Description Andy Lutomirski 2013-12-16 20:48:32 UTC

Setting /etc/ssh/moduli to mode 0600 adds very little security: it's straightforward to probe the contents by connecting over ssh and politely asking the server to do a group exchange.

On the other hand, making /etc/ssh/moduli unreadable by non-root users causes a real problem: it prevents things like Paramiko from reading and using it as a source of kex groups.

Ubuntu, by comparison, sets the mode to 0644.
