8 8Host configuration
9=========================================================================== 9==================
10Important change since 3.7.1p2-2:
11
12The ssh-host-config file doesn't create the /etc/ssh_config and
13/etc/sshd_config files from builtin here-scripts anymore, but it uses
14skeleton files installed in /etc/defaults/etc.
15
16Also it now tries hard to create appropriate permissions on files.
17Same applies for ssh-user-config.
18
19After creating the sshd service with ssh-host-config, it's advisable to
20call ssh-user-config for all affected users, also already exising user
21configurations. In the latter case, file and directory permissions are
22checked and changed, if requireed to match the host configuration.
23
24Important note for Windows 2003 Server users:
25---------------------------------------------
26
272003 Server has a funny new feature. When starting services under SYSTEM
28account, these services have nearly all user rights which SYSTEM holds...
29except for the "Create a token object" right, which is needed to allow
30public key authentication :-(
31
32There's no way around this, except for creating a substitute account which
33has the appropriate privileges. Basically, this account should be member
34of the administrators group, plus it should have the following user rights:
35
36 Create a token object
37 Logon as a service
38 Replace a process level token
39 Increase Quota
40
41The ssh-host-config script asks you, if it should create such an account,
42called "sshd_server". If you say "no" here, you're on your own. Please
43follow the instruction in ssh-host-config exactly if possible. Note that
44ssh-user-config sets the permissions on 2003 Server machines dependent of
45whether a sshd_server account exists or not.
46===========================================================================
47
48===========================================================================
49Important change since 3.4p1-2:
50
51This version adds privilege separation as default setting, see
52/usr/doc/openssh/README.privsep. According to that document the
53privsep feature requires a non-privileged account called 'sshd'.
54
55The new ssh-host-config file which is part of this version asks
56to create 'sshd' as local user if you want to use privilege
57separation. If you confirm, it creates that NT user and adds
58the necessary entry to /etc/passwd.
59
60On 9x/Me systems the script just sets UsePrivilegeSeparation to "no"
61since that feature doesn't make any sense on a system which doesn't
62differ between privileged and unprivileged users.
63
64The new ssh-host-config script also adds the /var/empty directory
65needed by privilege separation. When creating the /var/empty directory
66by yourself, please note that in contrast to the README.privsep document
67the owner sshould not be "root" but the user which is running sshd. So,
68in the standard configuration this is SYSTEM. The ssh-host-config script
69chowns /var/empty accordingly.
70===========================================================================
71
72===========================================================================
73Important change since 3.0.1p1-2:
74
75This version introduces the ability to register sshd as service on
76Windows 9x/Me systems. This is done only when the options -D and/or
77-d are not given.
78===========================================================================
79
80===========================================================================
81Important change since 2.9p2:
82
83Since Cygwin is able to switch user context without password beginning
84with version 1.3.2, OpenSSH now allows to do so when it's running under
85a version >= 1.3.2. Keep in mind that `ntsec' has to be activated to
86allow that feature.
87===========================================================================
88
89===========================================================================
90Important change since 2.3.0p1:
91
92When using `ntea' or `ntsec' you now have to care for the ownership
93and permission bits of your host key files and your private key files.
94The host key files have to be owned by the NT account which starts
95sshd. The user key files have to be owned by the user. The permission
96bits of the private key files (host and user) have to be at least
97rw------- (0600)!
98
99Note that this is forced under `ntsec' only if the files are on a NTFS
100filesystem (which is recommended) due to the lack of any basic security
101features of the FAT/FAT32 filesystems.

176 CAUTION: The SID _must_ remain the _last_ field in pw_gecos!
177 BTW: The field separator in pw_gecos is the comma.
