I have installed Ubuntu Desktop 16.04.4 on ESXi 6.0. Tried to increase the pixel density so that i can view the big Screen on my other 27 inch screen through VMWare client. I tried installing open-vmtools but remained unsuccessful. Then installed VMWare tools by mounting through VMWare client (tools that come with ESXi 6.0 but again remained unsuccessfull. The third try was to download latest VMtools from VMWare website, uploaded to uploaded to the /tmp folder of ubuntu through WinSCP server and then installed as per given procedure on VMWare website. I shut down the Ubuntu VM Increase the Video Card Memory from Default to 16 MB. Restarted Virtual Machine, this time I was getting bunch of options for increasing screen size of the Ubuntu Display and successfully running my VM at  resolution of 1440x900 (16:10).

cannot start console applications: [WinError 2] The system cannot find the file specified. I got this error, upon checking I found that I had not installed wireshark during installing gns3. Installed wireshark separately and the error is gone. I did no configuration except installing wireshark.  I can see and capture traffic on gns3 device's interfaces by just right clicking any interface and then clicking "start wireshark".

The term bridging refers to a technology in which a device known as a bridge connects two or more LAN segments. Bridges are OSI Data Link layer, or Layer 2, devices that were originally designed to connect two network segments. Multiport bridges were introduced later to connect more than two network segments, these devices analyze the frames as they come in and make forwarding decisions based on information in the frames themselves. Bridges learn the location of the network stations without any intervention from a network administrator or any manual configuration of the bridge software. This process is commonly referred to as self−learning. When a bridge is turned on and begins to operate, it examines the MAC addresses located in the headers of frames passed through the network. As the traffic passes through the bridge, the bridge builds a table of known source addresses, assuming the port from which the bridge received the frame is the port to which the device is a sending device

I have a very old Sun Solaris Server running on on SPARC platform # cat /etc/release                        Solaris 10 6/06 s10s_u2wos_09a SPARC            Copyright 2006 Sun Microsystems, Inc.  All Rights Reserved.                         Use is subject to license terms.                              Assembled 09 June 2006 Running an old java application server on it $ asadmin version Unable to communicate with admin server, getting version locally. Version = Sun Java System Application Server Platform Edition 8.2 Command version executed successfully. We had a planned power shut at our office so we needed to shut the servers down for few hours, after the shut down window, I started the servers - servers boot successfully but while starting the  application server i was getting output "null" the server even was not writing any logs to the server.log file asadmin> start-domain Starting Domain domain1, please wait.

Before installing an VMWare ESXi server i was little curious that what VMTools version will come after the ESXi have been installed and any VM has been created. Looking around found a link on VMWare worth to share and keep handy while working on the deployment of VMWare especially before upgrading and existing VMWare infrastructure to newer one you would like to know the VMTools version, its support with your Operating Systems in Guest OS and/or read upon open or resolved caveats by identifying the VMTools version prior the installation and choosing the right version for your environment. Below information has been collected from the link  here # The ESXi server mapping is only to show that the particular version of # Tools ships with that particular ESXi server build number, but the Tools # can work with a greater range of ESXi versions. # # Column 1: Tools version on NGC/VI Client # Column 2: ESXi server version.'esx/0.0' indicates that the tools version # is not yet bu
