This package is the actual port of OpenSSH to Cygwin 1.1.
|
|
|
|
===========================================================================
|
|
Important change since 2.3.0p1:
|
|
|
|
When using `ntea' or `ntsec' you now have to care for the ownership
|
|
and permission bits of your host key files and your private key files.
|
|
The host key files have to be owned by the NT account which starts
|
|
sshd. The user key files have to be owned by the user. The permission
|
|
bits of the private key files (host and user) have to be at least
|
|
rw------- (0600)!
|
|
|
|
Note that this is forced under `ntsec' only if the files are on a NTFS
|
|
filesystem (which is recommended) due to the lack of any basic security
|
|
features of the FAT/FAT32 filesystems.
|
|
===========================================================================
|
|
|
|
Since this package is part of the base distribution now, the location
|
|
of the files has changed from /usr/local to /usr. The global configuration
|
|
files are in /etc now.
|
|
|
|
If you are installing OpenSSH the first time, you can generate
|
|
global config files, server keys and your own user keys by running
|
|
|
|
/usr/bin/ssh-config
|
|
|
|
If you are updating your installation you may run the above ssh-config
|
|
as well to move your configuration files to the new location and to
|
|
erase the files at the old location.
|
|
|
|
Be sure to start the new ssh-config when updating!
|
|
|
|
Note that this binary archive doesn't contain default config files in /etc.
|
|
That files are only created if ssh-config is started.
|
|
|
|
Install sshd as daemon via SRVANY.EXE (recommended on NT/W2K), via inetd
|
|
(results in very slow deamon startup!) or from the command line (recommended
|
|
on 9X/ME).
|
|
|
|
If starting via inetd, copy sshd to eg. /usr/sbin/in.sshd and add the
|
|
following line to your inetd.conf file:
|
|
|
|
sshd stream tcp nowait root /usr/sbin/in.sshd sshd -i
|
|
|
|
Moreover you'll have to add the following line to your
|
|
${SYSTEMROOT}/system32/drivers/etc/services file:
|
|
|
|
sshd 22/tcp #SSH daemon
|
|
|
|
Authentication to sshd is possible in one of two ways.
|
|
You'll have to decide before starting sshd!
|
|
|
|
- If you want to authenticate via RSA and you want to login to that
|
|
machine to exactly one user account you can do so by running sshd
|
|
under that user account. You must change /etc/sshd_config
|
|
to contain the following:
|
|
|
|
RSAAuthentication yes
|
|
|
|
Moreover it's possible to use rhosts and/or rhosts with
|
|
RSA authentication by setting the following in sshd_config:
|
|
|
|
RhostsAuthentication yes
|
|
RhostsRSAAuthentication yes
|
|
|
|
- If you want to be able to login to different user accounts you'll
|
|
have to start sshd under system account or any other account that
|
|
is able to switch user context. Note that administrators are _not_
|
|
able to do that by default! You'll have to give the following
|
|
special user rights to the user:
|
|
"Act as part of the operating system"
|
|
"Replace process level token"
|
|
"Increase quotas"
|
|
and if used via service manager
|
|
"Logon as a service".
|
|
|
|
The system account does of course own that user rights by default.
|
|
|
|
Unfortunately, if you choose that way, you can only logon with
|
|
NT password authentification and you should change
|
|
/etc/sshd_config to contain the following:
|
|
|
|
PasswordAuthentication yes
|
|
RhostsAuthentication no
|
|
RhostsRSAAuthentication no
|
|
RSAAuthentication no
|
|
|
|
However you can login to the user which has started sshd with
|
|
RSA authentication anyway. If you want that, change the RSA
|
|
authentication setting back to "yes":
|
|
|
|
RSAAuthentication yes
|
|
|
|
You may use all features of the CYGWIN=ntsec setting the same
|
|
way as they are used by the `login' port on sources.redhat.com:
|
|
|
|
The pw_gecos field may contain an additional field, that begins
|
|
with (upper case!) "U-", followed by the domain and the username
|
|
separated by a backslash.
|
|
CAUTION: The SID _must_ remain the _last_ field in pw_gecos!
|
|
BTW: The field separator in pw_gecos is the comma.
|
|
The username in pw_name itself may be any nice name:
|
|
|
|
domuser::1104:513:John Doe,U-domain\user,S-1-5-21-...
|
|
|
|
Now you may use `domuser' as your login name with telnet!
|
|
This is possible additionally for local users, if you don't like
|
|
your NT login name ;-) You only have to leave out the domain:
|
|
|
|
locuser::1104:513:John Doe,U-user,S-1-5-21-...
|
|
|
|
V2 server and user keys are generated by `ssh-config'. If you want to
|
|
create DSA keys by yourself, call ssh-keygen with `-d' option.
|
|
|
|
DSA authentication similar to RSA:
|
|
Add keys to ~/.ssh/authorized_keys2
|
|
Interop. w/ ssh.com dsa-keys:
|
|
ssh-keygen -f /key/from/ssh.com -X >> ~/.ssh/authorized_keys2
|
|
and vice versa:
|
|
ssh-keygen -f /privatekey/from/openssh -x > ~/.ssh2/mykey.pub
|
|
echo Key mykey.pub >> ~/.ssh2/authorization
|
|
|
|
If you want to build from source, the following options to
|
|
configure are used for the Cygwin binary distribution:
|
|
|
|
--prefix=/usr --sysconfdir=/etc --libexecdir='${exec_prefix}/sbin
|
|
|
|
You must have installed the zlib, openssl and regex packages to
|
|
be able to build OpenSSH!
|
|
|
|
Please send requests, error reports etc. to cygwin@sources.redhat.com.
|
|
|
|
Have fun,
