  1. The.pub file is your public key, and the other file is the corresponding private key. If you don’t have these files (or you don’t even have a.ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/macOS systems and comes with Git for Windows.
  2. Before you can access IBM Commerce on Cloud servers or environments, you must generate a pair of public and private keys for SSH logon and provide IBM the public key. You can use the Cygwin key generator utility to create the public and private keys for SSH logon that you need for accessing IBM Commerce on Cloud environment servers and applications.

Generate Ssh Key Cygwin

Generate the key using the Cygwin shell You can now run standard ssh commands that you see documented on the plethora of Linux and Unix websites on the internet. Right now, the command you really want to run is: $ ssh-keygen -t rsa. Before using ssh, MobaXterm requires a persistent home directory. Go to Settings and set the persistent home directory. First step is to generate the ssh key, therefore open a local terminal and generate a key (rsa) with this command: ssh-keygen -t rsa The output. Generating public/private rsa key pair. Sep 26, 2019  To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. System mechanic 14 activation key generator. The standard OpenSSH suite of tools contains the ssh-keygen utility, which is used to generate key pairs. Mechanical engineering design projects pdf. Run it on your local computer to generate a 2048-bit RSA key pair, which is fine for most uses.

CREATE SFTP SERVER using CYGWIN

This blog is useful for you if :
1. You want to setup SFTP on Windows
2. If you want to restrict user to a directory on SFTP (using openssh)

Some background inforamtion :
What is SFTP read here
What is OpenSSH read here
What is cygwin read here
Content
  • Install SFTP-server, Cygwin with OpenSSH
  • Configure home-directory
  • Configure SSH-server
  • Start the SSH-service
  • Generate SSH-keys
  • Test login to SFTP-server
  • Uninstall the SSH-service
  • Restrict User to a directory
Install SFTP-server, Cygwin with OpenSSH
  1. Download setup.exe from http://www.cygwin.com/ and save the file to 'c:cygwincygwin.install' (you will have to 1. create the directory).
  2. Run setup.exe and follow instructions below:



Configure home-directory
Note: This step is necessary if roaming profiles are used in Windows.
1. Start Cygwin
2. Open 'c:cygwinetcpasswd' with a text editor (Notepad for example)
3. In passwd, change home-dir from '/home' to 'C:Documents and Settings' (example below for user id:
dfc0364).
Change:
dfc0364:unused_by...-1851:/home/dfc0364:/bin/bash
to:
dfc0364:unused_by...-1851:/cygdrive/c/Documents and Settings/dfc0364:/bin/bash
1. Close Cygwin
Configure SSH-server
Configure the SSH-server (sshd) in a Cygwin window:
$ ssh-host-config
*** Info: Generating /etc/ssh_host_key
*** Info: Generating /etc/ssh_host_rsa_key
*** Info: Generating /etc/ssh_host_dsa_key
*** Info: Creating default /etc/ssh_config file
*** Info: Creating default /etc/sshd_config file
*** Info: Privilege separation is set to yes by default since OpenSSH 3.3.
*** Info: However, this requires a non-privileged account called 'sshd'.
*** Info: For more info on privilege separation read /usr/share/doc/openssh/README.privsep.
*** Query: Should privilege separation be used? (yes/no) yes
*** Info: Updating /etc/sshd_config file
*** Warning: The following functions require administrator privileges!
*** Query: Do you want to install sshd as a service?
*** Query: (Say 'no' if it is already installed as a service) (yes/no) yes
*** Info: Note that the CYGWIN variable must contain at least 'ntsec'
*** Info: for sshd to be able to change user context without password.
*** Query: Enter the value of CYGWIN for the daemon: [ntsec]
*** Info: The sshd service has been installed under the LocalSystem
*** Info: account (also known as SYSTEM). To start the service now, call
*** Info: `net start sshd' or `cygrunsrv -S sshd'. Otherwise, it
*** Info: will start automatically after the next reboot.
*** Info: Host configuration finished. Have fun!

Start the SSH-service
Start the SSH-server (sshd) in a Cygwin window:
$ cygrunsrv --start sshd
Generate SSH-keys
Note: Remember your passphrase, you will have to configure it in your service components security-property-file in order to connect to your
local SFTP-server.
Generate the SSH-keys to use for public-key cryptography in a Cygwin window:
$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/cygdrive/c/Documents and Settings/dfc0364/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /cygdrive/c/Documents and Settings/dfc0364/.ssh/id_dsa.
Your public key has been saved in /cygdrive/c/Documents and Settings/dfc0364/.ssh/id_dsa.pub.
The key fingerprint is:
07:5c:3f:f6:8e:b5:91:de:02:5c:c3:c8:3a:04:3f:aa dfc0364@dse31673
The key's randomart image is:
+--[ DSA 1024]----+
. .
. + o o
o + * +
+ = + o
S + o =
. . . * +
E . = .
.

+-----------------+
dfc0364@dse31673 ~
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys2
Test login to SFTP-server
Test to login to your local SFTP-server in a Cygwin window (example for user id: dfc0364):
$ sftp dfc0364@localhost
Connecting to localhost.
Enter passphrase for key '/cygdrive/c/Documents and Settings/dfc0364/.ssh/id_dsa':
sftp> exit
Uninstall the SSH-service
If you want to uninstall the SSH-service, open up Cygwin and execute commands:
cygrunsrv --stop sshd
cygrunsrv --remove sshd

Restrict User to a directory
Open etc folder in your cygwin installation. Two file need a edit to to implement chroot jail for user.
1. sshd_config
2. passwd
in sshd_config change below conigurtions

# override default of no subsystems
Subsystem sftp internal-sftp
ChrootDirectory /cygdrive/d/inetpub/ftproot
# Example of overriding settings on a per-user basis
Match User administrators
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
in passwd file
manually edit root user to change the group id (usually 544) to 0
for example as below :
SvcCOPSSH:unused_by_nt/2000/xp:0:545:U-WINDOWS-AU90FH5SvcCOPSSH,S-1-5-21-2943273595-299576109-709065550-1031:/var/:/bin/false
Restart OPENSSH service and Enjoy !
