    mRemoteNG Serial Connection

    mRemoteNG Serial Connection



    Its is impossible to simply create a serial connection on mRemoteNG ( a least at 1.67 version) so there is a tip to do that.

    1 Using Putty Session

    - Download putty.exe and copy it so somewhere ( example to "C:\1")
    - Open putty.exe, create Serial Connection, and save it.Dont forget to choose baud rate ( example "COM_9600")
    - Open mRemoteNG go to external tools (Tools-External Tools), create new external tool ( example "PTTY_9600")
    - At the filename write path+filename ( example "C:\1\putty.exe")
    - At the argumets write putty.exe -load "CONNECTION_NAME) ( example "putty.exe -load "COM_9600")
    - Choose "Try to integrate" Option
    - Create new connection and in the protocol filed choose "Ext. App" then External tool "PTTY_9600" ( external tool name)

    2 - Using TeraTerm
    - install teratem ( i use v 4.70)
    - Create external tool, name it ( example TTRM_9600)
    - At the filename write path+filename ( example "C:\Program Files\teraterm\ttermpro.exe")
    -  At the argumets write "ttermpro.exe /BAUD=9600 /C=1"
       (/BAUD is baud rate and /C is COM port number)
    - Choose "Try to integrate" Option
    - Create new connection and in the protocol filed choose "Ext. App" then External tool "TTRM_9600" ( external tool name)

    Enjoy!

    mRemoteNG FileZilla SFTP



    How to integrate FileZilla SFTP support in mRemoteNG.
    First open up mRemoteNG then press “tools” and then “External Tools”

When we try to install or Upgrade VMware tools using vSphere client, It will automatically mount the associated VMware tools ISO into virtual CD ROM drive of your virtual machine based on the Guest Operating system of the virtual machine. If in case you face any problem with mounting VMware tools ISO image to the virtual machine using vSphere client, you can manually download the VMware tools from the VMware website and install it manually.
    You can even download the complete list of VMware tools available for various operating systems and place it in your organization repository to be used by administrators. It will make your job easy. VMware tools helps to optimize the performance of your virtual machine using ESX/ESXi  hypervisor resource management mechanisms.
    Using the above link you can Select the version of vSphere to download the VMware tools. I have Selected ESXi 5.1 U1 
    After selecting the ESX/ESXi version, It will allow us to select the Operating system to download the respective VMware tools version
    I have selected Windows in the above section and intern it will ask you to select either 32 bit or 64 bit of VMware tools version for the windows operating system.
    Choose either X64 or X86 based on your operating system of the Virtual Machine. It will allow  you to download VMware tools .exe file and also VMware tools ISO image.
    Thats it. You are done with the manual download of VMware tools for your guest operating system. I hope this post is informative for you. Thanks for Reading !!!

    High Disk Space is being consumed by C:\Program Files\Symantec\Symantec Endpoint Protection Manager\data\outbox\Importpackage

    . Delete all files from %installlocation%\Symantec\Symantec Endpoint Protection Manager\data\outbox\ImportPackage folder. (without stopping any services)
    2. Delete everything older than today's date in %installlocation%\Symantec\Symantec Endpoint Protection Manager\Inetpub\content (also without stopping any services)
    3. In the Symantec Admin Console go to Admin > Servers > localhost. Right-click localhost and truncate the transaction logs.


    Symantec has released new version of Symantec Endpoint Protection. English versions of Symantec Endpoint Protection 12.1.5337.5000 (RU5) is now available.
    It has new content storage optimization feature:
    As part of the upgrade to SEPM 12.1 RU5, the SEPM converts all of the content from full definitions to delta definitions. This process is resource intensive and may take an extended period of time. After this process is completed, the SEPM will use significantly less disk space.
    In a typical enterprise setup where 30 content revisions stored, the SEPM upgrade process must reduce 55GB of full content to under 2GB of delta content. This process requires significant resources to complete and is impacted by the performance of any available CPUs, CPU cores (physical/logical/hyperthreading), memory, and disks (I/O). On a server that performs multiple roles, stores larger numbers of content, or is otherwise resource constrained, this process may take a longer duration to complete.
    Refer this article to find more info: The LiveUpdate content optimization and content storage space optimization steps take a long time to complete when upgrading to Symantec Endpoint Protection Manager 12.1 RU5

    vCenter Server Appliance: Troubleshooting full database partition



    A customer of mine had within 6 months twice a full database partition on a VMware vCenter Server Appliance. After the first outage, the customer increased the size of the partition which is mounted to /storage/db. Some months later, some days ago, the vCSA became unresponsive again. Again because of a filled up database partition. The customer increased the size of the database partition again  (~ 200 GB!!) and today I had time to take a look at this nasty vCSA.
    The situation
    vcsa_overview
    Within 2 days, the storage usage of the databse increased from 75% to 77%. First, I checked the size of the database:
     As you can see, the database had only 2 GB. The pg_log directory was more interesting:
     The directory was full with log files. The log files containted only one message:
    The solution
    This led me to VMware KB2092127 (After upgrading to vCenter Server Appliance 5.5 Update 2, pg_log file reports this error: WARNING: there is already a transaction in progress). And yes, this appliance was upgraded to U2 with high probability. The solution is described in KB2092127, and is really easy to implement. Please note that this is only a workaround. There’s currently no solution, as mentioned in the article.

    How to connect/interact with VCVA DB (DB2 and vPostgres)

    If you need to connect/interact with the VC appliance database, for example to remove the locks of DB2 or performing an script, you can do the following after being logged in as root via SSH on the appliance:

    - On VCVA 5.0 GA with DB2:

    1. Turn into the db2inst user:

    vcenter:/ # su db2inst1

    2. Start the db2 client:

    db2inst1@vcenter:/> db2

    You'll see a prompt like this:

    db2 =>

    3. connect to the VCDB database:

    db2 => connect to VCDB

    (the command is like this, very literal)

    4. Change to VC schema:

    db2 => set schema vc

    5. Perform any command you need. For example, to remove the VPX_SESSIONLOCK lines, you can do like this:

    db2 => delete from VPX_SESSIONLOCK
    DB20000I  The SQL command completed successfully.


    You can type "quit" anytime you want to exit from the db2 client, and "exit" when you want to go back to root userspace.

    - On VCVA with vPostgres:

    1. Connect to the database using psql:

    vcenter:/ # /opt/vmware/vpostgres/1.0/bin/psql -U vc -d VCDB

    You'll see a prompt like this:

    psql (9.0.4)
    Type "help" for help.


    VCDB=>

    2. Perform any command you need (selects, inserts, etc). For example, to list all tables:

    VCDB=> \dt

    There are a lot of new tables in 5.1, (mainly the vpx_hist_stat* ones).

    To quit, just type "\q"

    Changing the default VMware vCenter Server Appliance database password (2056968)

    Changing the default VMware vCenter Server Appliance database password

     

     

    Details

    You can change the default password for the VMware vCenter Server Appliance database when you want or if the password is compromised.

    Solution

    To change the default:
    1. Change the embedded database password:

      1. Connect to the vCenter Server Appliance using SSH.
      2. Open the embedded_db.cfg file for editing with this command:

        vi /etc/vmware-vpx/embedded_db.cfg

      3. In the file, locate EMB_DB_PASSWORD and change the password between the single quotation marks.
    2. Change the password for the vc and postgres database users:

      1. Connect to the vPostgres database for SQL execution by running this command:

        /opt/vmware/vpostgres/current/bin/psql -d VCDB U postgres

      2. Run these SQL statements to change the passwords for the vc and postgres users:

        alter user postgres with password 'new-password';
        alter user vc with password 'new-password';

      3. Exit the database with this command:

        \q

      4. Open the .pgpass file for editing by running this command:

        vi /root/.pgpass
      5. Modify the .pgpass file with the new password as follows:

        localhost:5432:VCDB:postgres:new-password
        localhost:5432:postgres:postgres:new-password
        localhost:5432:VCDB:vc:new-password
    3. Change the postgres database password:

      1. To change the password for the vPostgres database by running this command:

        passwd postgres

      2. Type the new password.
      3. Retype the new password.
    4. To update the encrypted password in the vpxd.cfg file, run this command:

      /usr/sbin/vpxd -p

    5. Enter the password when prompted.
    6. Run this command to restart the vpxd service:

      /etc/init.d/vmware-vpxd restart

    vCenter Appliance – Call “EventHistoryCollector.SetLatestPageSize” for object “SessionID” on vCenter Server failed.

    When using the vSphere Client to connect to the VMware vCenter Server Appliance was appearing every now and again.

    Call “EventHistoryCollector.SetLatestPageSize” for object “SessionID” on vCenter Server “ServerName” failed. (unfortunately didnt take a screenshot, so here’s one I found and modified).
    2014-10-20_09-18-39

    This issue is pretty common, and is to do with the amount of events in the database not being purged, and is covered by VMware in this KB article for windows environments.
    However not so commonly covered for the vCenter Appliance which uses a progress database.

    After a bit of digging around, I found the following crude solution on the VMware communities board.

    So open up a console to your VCSA, login in. Run the following commands
    /opt/vmware/vpostgres/1.0/bin/psql -d VCDB vc 
    TRUNCATE TABLE vpx_event CASCADE;
    then to exit “/q”

    Here are the steps:
    1. First of all - stop VPXD
      •  service vmware-vxpd stop
    2. connect to DB:
      /opt/vmware/vpostgres/1.0/bin/psql -d VCDB vc 
       
      You will be prompted for the "vc" password which is not the same as the 
      root password.
       
      Password is in "/etc/vmware-vpx/embedded_db.cfg" file
       
       
    3. issue this commands:
      2014-10-20_08-59-04
      • TRUNCATE TABLE vpx_event CASCADE;
      • TRUNCATE TABLE vpx_event_arg CASCADE;
      • TRUNCATE TABLE vpx_task CASCADE;
    4. quit DB command line
      • issue the command "/q "
    5. start the VPXD
      •  service vmware-vxpd start or restart vCSA appliance
    6. Check the size of VCBD.  Now the size is only 165MB
        • VCDB=> SELECT pg_database.datname, pg_size_pretty(pg_database_size(pg_database.datname)) AS size FROM pg_database;
        •   datname  |  size
        1. -----------+---------
           template1 | 5289 kB
           template0 | 5281 kB
           postgres  | 5385 kB
           VCDB      | 165 MB
          (4 rows)

      VMware vCenter Server Appliance Error: VPXD must be stopped to perform this operation.

      http://www.virtualizationteam.com/management-automation/vmware-vcenter-server-appliance-error-vpxd-must-be-stopped-to-perform-this-operation.html


      Error: VPXD must be stopped to perform this operation.
      This error has came up while trying to change authentication to active directory authentication and kinda seen the same error when trying to change the database to an external database. For some reason the Server service stop button is shadowed as well which mean I could not stop it by the GUI interface. Although my lab setup is not ideal and it might just due to the way I set it up, though I will still document how I resolved this where the same mechanism can be used to stop and restart any other service used by the vCenter Server Appliance. Below are the steps I have followed:
      1- SSH to your VMware vCenter Server Appliance using the root account.
      2- Execute the following command to see the status of all the service running in the vCenter Appliance:   chkconfig
      The output of all services will look something like below:
