KB ID 0000644 

Problem

If you connect to a lot of ESX, ESXi and vCenter machines, the drop down list in your VI client can get a little cluttered.

Solution

1. Start > Run > Regedit {enter}

2. Navigate to;

[box]HKEY_CURRENT_CURRENT_USERSoftwareVMwareVMware Infrastructure ClientPreferences[/box]

Locate the ‘RecentConnections’ string value, and either delete them all, (or just the ones you no longer need).

3. Now things will be a little less cluttered.

Postfix – Change The ‘Welcome Banner’

Posted on by

KB ID 0000907

Problem

After my recent DNS troubles, I was checking my mail server’s (MX) records, and got a warning about not having any reverse lookup records (PTR) configured properly. I telnetted to the mail server on port 25, and saw it was responding with the servers host-name.

I know my records are correct for the FQDN of the server, I just needed to change its welcome banner.

Solution

Change the Postfix Welcome Banner by Editing The Postfix main.cf File

1. Connect to the server via SSH, (or open a terminal session). Logon as, (or su to) root.

2. Execute the following command;

[box]

nano /etc/postfix/main.cf

[/box]

3. Locate and edit the myhostname value, to match your servers public FQDN.

4. Once you have saved and exited nano, restart the Postfix service with the following command;

[box]postfix stop && postfix start[/box]

Change the Postfix Welcome Banner Using Webmin

1. Connect to the Webmin console > Postfix Mail server > General Options.

4. Scroll down to internet host-name of this mail system > Edit to match your servers public FQDN > Save and Apply.

5. Stop then Start Postfix.
