At least having sshd emit a warning is a prerequisite, certainly. I don't yet know if there's a way via libwrap's API to determine if rules are in place; there's a bit of investigation needed here still. > I do understand the burden of maintaining a local patch (we lost the HA > patches from base this way already). Indeed. As you pointed out the libwrap patch is very small and easy to review and reason about. My bigger concern is that libwrap is essentially abandonware, and it has been dropped by just about everyone else. As far as I know Debian is still patching libwrap support into sshd but not anyone else. It seems starting sshd from inetd via tcpd is a reasonable approach for folks who want to use it; also, have folks using libwrap looked at sshd's Match blocks to see if they provide the desired functionality?Received on Fri Feb 21 2020 - 15:49:33 UTC
