1 Next-Steps Monkeysphere Projects:
2 ---------------------------------
4 Detail advantages of monkeysphere: detail the race conditions in ssh,
5 and how the monkeysphere can help you reduce these threat vectors:
6 threat model reduction diagrams.
8 Determine how openssh handles multiple processes writing to
9 known_hosts/authorized_keys files (lockfile, atomic appends?)
11 Handle unverified monkeysphere hosts in such a way that they're not
12 always removed from known_hosts file. Ask user to lsign the host
15 Handle multiple hostnames (multiple user IDs?) when generating host
18 Work out the details (and describe a full use case) for assigning a
19 REVOKER during monkeysphere-server gen_key -- how is this set? How
20 do we export it so it's available when a second-party revocation is
23 Actually enable server hostkey publication.
25 Streamline host key generation, publication, verification. See
26 doc/george/host-key-publication for what dkg went through on
29 Streamline authorized_user_ids setup (including question of where
30 authorized_user_ids files should go). See
31 doc/george/user-id-configuration for what dkg went through on
34 Ensure that authorized_user_ids are under as tight control as ssh
35 expects from authorized_keys: we don't want monkeysphere to be a
36 weak link in the filesystem.
38 What happens when there are no entries in the authorized_user_ids file
39 for a user? /var/cache/monkeysphere/authorized_keys/$USER.tmp
40 seems like it gets created and then left there.
42 What happens when a user account has no corresponding
43 /etc/monkeysphere/authorized_user_ids/$USER file? What gets placed
44 in /var/cache/monkeysphere/authorized_keys/$USER? It looks
45 currently untouched, which could mean bad things for such a user.
47 Consider the default permissions for
48 /var/cache/monkeysphere/authorized_keys/* (and indeed the whole
49 directory path leading up to that)
51 What should happen when an admin does
52 "monkeysphere-server update-users not_an_existent_user"?
54 /etc/monkeysphere/authorized_user_ids/not_an_existent_user, which
57 is /var/cache/monkeysphere/authorized_keys/$USER.tmp guaranteed to
58 avoid collisions? Why not use a real mktemp file?
60 As an administrator, how do i reverse the effect of a
61 "monkeysphere-server trust-keys" that i later decide i should not
64 Make sure alternate ports are handled for known_hosts.
66 Script to import private key into ssh agent.
68 Provide a friendly interactive UI for marginal or failing client-side
69 hostkey verifications. Handle the common cases smoothly, and
70 provide good debugging info for the unusual cases.
72 Make sure onak properly escapes user IDs with colons in them.
74 Build a decent, presentable web site for documentation, evangelism,
75 etc. Include a mention of how to report trouble or concerns.
77 Create ssh2openpgp or convert to full-fledged keytrans.
79 Resolve the bugs listed in openpgp2ssh(1):BUGS.
81 Understand and document alternate trustdb models.
83 Understand and document the output of gpg --check-trustdb:
84 gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
85 gpg: depth: 0 valid: 2 signed: 20 trust: 0-, 0q, 0n, 0m, 0f, 2u
86 gpg: depth: 1 valid: 20 signed: 67 trust: 15-, 0q, 1n, 3m, 1f, 0u
87 gpg: next trustdb check due at 2008-10-09
89 Understand and document the numeric values between sig! and the keyid
90 in "gpg --check-sigs $KEYID" . Compare with the details found from
91 "gpg --with-colons --check-sigs $KEYID". This has to do with trust
94 Fix gpg's documentation to clarify the difference between validity and
95 ownertrust. Include better documentation for trust signatures.
97 Make it easier to do domain-relative ssh host trust signatures with
98 gnupg. (e.g. "i trust Jamie McClelland (keyID 76CC057D) to properly
99 identify ssh servers in the mayfirst.org domain") See:
100 http://tools.ietf.org/html/rfc4880#section-5.2.3.21 and grep for
103 Fix the order of questions when user does a tsign in gpg or gpg2.
105 File bug against ssh-keygen about how "-R" option removes comments
106 from known_hosts file.
108 File bug against ssh-keygen to see if we can get it to write to hash a
109 known_hosts file to/from stdout/stdin.
111 Add environment variables sections to man pages.
113 Environment variable scoping.
115 Move environment variable precedence before conf file.
117 When using ssh-proxycommand, if only host keys found are expired or
118 revoked, then output loud warning with prompt, or fail hard.
120 Update monkeysphere-ssh-proxycommand man page with new keyserver
121 checking policy info.
123 Update monkeysphere-ssh-proxycommand man page with info about
