Subject: Also require $SSH_CONNECTION to be unset or warn
X-Git-Tag: 0.3.1~1
X-Git-Url: https://git.madduck.net/code/molly-guard.git/commitdiff_plain/86a25141cdf635e1386d9fbfd3b15febfec778bc?hp=048c6a97f910e0dc1401015065cf56ff9bc86e19

Also require $SSH_CONNECTION to be unset or warn

This takes care of some more cases, such as #469951, in which screen was
used, which creates a new pty which is thus no longer owned by sshd.
