Creating a Remote Mailbox in an Exchange Hybrid Environment Friday, May 13, If you operate an Exchange hybrid environment you will eventually want to create Exchange Online mailboxes for new users without creating them on-premises and migrating them. The easiest way to do this is to create the new user object and remote mailbox from the on-prem Exchange Admin Center EAC. Logon to the on-premises Exchange Admin Center. Fill out the webpage to create the new user object in AD and click Save.

There are key utilities, command-line chains, and scripts that are used to simplify different processes. Some of these tools come with the operating system, but a majority of the tricks come through years of experience and a desire to ease the system administrator's life.
The focus of this series is on getting the most from the available tools across a range of different UNIX environments, including methods of simplifying administration in a heterogeneous environment.
The standard networking services that you use every day, such as FTP, Telnet, RCP, remote shell rshand so forth, are fine within a closed environment, but the information that you transfer over the network with any of these services is not encrypted.
Anybody with a packet sniffer on your network or on a remote machine can view the information as it is exchanged, sometimes even password information. Furthermore, with all of these services, the options for auto-login during the process are limited, and often rely on embedding the plain text password into the command line to execute a statement, making the process even more insecure.
SSH provides for encryption of the entire communication channel, including the login and password credential exchange, and it can be used with public and private keys to provide automatic authentication for logins. You can also use SSH as an underlying transport protocol. The remote environment SSH in this way means that once you have opened a secure connection, the encrypted channel can exchange all types of information, even HTTP and SMTP, using the same, secure communication mechanism.
You can often find a precompiled binary for your chosen platform and version. Some vendors even provide the OpenSSH kit as part of the operating system. To build, you need the following: If you want to integrate the tools into your main environment, then you might want to specify the --prefix option, which sets the base directory, and the --sysconfdir option, which sets the location of the configuration files: Once configured, build as normal with make.
With the build and installation process completed, you need to configure your system, starting with creating the SSH keys that uniquely identify your system and enable secure communication between clients and your host. You need to create three keys one for each of the main encryption algorithms: For example, Listing 2 shows you how to create an rsa1 key.
Enter passphrase empty for no passphrase: Enter same passphrase again: The key fingerprint is: For host keys, you probably don't want a passphrase for the key, so you can just press Return to use a blank empty passphrase. Alternatively, you can speed up the process by using the -N option on the command line see Listing 3.
You should ensure that the private keys are readable only by root and the SSH processes -- this should be configured automatically. You might want to copy the public keys to a central location on a Network File System NFS share to enable people to add them to the known host keys list.
Finally, you need to start the sshd process and configure it to execute at boot time. To connect to a remote host using the standard shell, you can just type the name of the host: To use a different login, prefix the hostname and separate the two with the sign.
The first time you connect to a host, the system asks if you want to keep a copy of the remote hosts public key in your 'known hosts' file see Listing 5. RSA key fingerprint is cc: Permanently added 'remotehost' RSA to the list of known hosts. In the future, you won't get this warning, but a warning is sent if the system detects a difference in the public key returned by the remote host and the public key that you have on file for that host, as this might indicate a potential hacking attempt.
It can also mean that the administrator has simply regenerated the host keys. In essence, there are no differences between an SSH and a Telnet session, except that the SSH session is encrypted, making it almost impossible for somebody to snoop on your session and determine your password or the commands and operations you are executing.
You can also use SSH to run a command directly on a remote host without having to use the shell. For example, see Listing 6 to run the who command on a remote host. This means that you can redirect output to a remote command. For example, you can append information directly to a remote file by piping the output from the command to an SSH on a remote host see Listing 7.
To open an SFTP connection, specify the hostname on the command line:You can deploy a Remote Desktop Connection Broker (RD Connection Broker) cluster to improve the availability and scale of your Remote Desktop Services infrastructure.
Set up a server to act as a second RD Connection Broker - this can be either a physical server or a VM.
