How to check if SSH is working over VNC

Hi, I'm somewhat of a computer noob. Biology is more of my thang.
In any case I've set up port forwarding on my router so I can access my iMac from school using my Macbook air. I use the native/built-in OSX VNC client to access files and screen share. It has been a little buggy lately, but it is really quite convenient and it was easy to set up, and I like that I can restrict access to prevent users from attempting to connect unless they are signed into my my AppleID on their computer.
However, after much reading I am beginning to realize that the connection is secure/encrypted, but the session itself might not be encrypted, such that anything I'm doing remotely on my iMac is completely unencrypted for the intelligent hacker to sniff out. So I have a few questions...
1) I have a paid subscription to a private VPN client. If I turn on my VPN and then VNC through to my iMac, will my session be encrypted?
2) I have port forwarding set up at 5900, so if I enter "ssh user@imac -L 5900:127.0.0.1:5900" in Terminal and then VNC to my iMac, will that VNC connection automatically be tunneled through the SSH encryption?
3) If the answer to either 1 and 2 is "yes," is there a way I can verify/test to make sure that all traffic is being directed through the VPN or SSH and that is encrypted?
4) Any other pertinent remote-connection security features/cool learning tricks for a noob such as myself would be greatly appreciated!
Cheers,

  • Time Machine: How to check that it's working?

    hey guys, i just ran Time Machine for the first time and it looks like everything worked ok. it completed the backup and will run another backup in 20 minutes. i was just wondering how i can check that my files are actually being backed up in case i had to restore the files. how would i go about restoring the files by the way? i can't see an option to do this.         
    thanks a lot

    ok i had a look at that, but couldn't find an answer to this:
    i just noticed that my time machine drive is 4gb smaller than my mac internal HDD. is there any reason for this?
    Yes, as softwater and others have said, Time Machine does skip some things, such as system work files, most caches and logs, etc.  The size of all that varies widely from time to time, but is usually several GBs.
    See the tan box in Time Machine - Frequently Asked Question #11 for the gory details.
    But the size of the data on your TM drive will grow as more backups are performed, copying only the items that are new or changed, eventually filling all the available space.  Then it will begin deleting the oldest backup(s) when it needs room for new ones.
    but doesn't Time Machine create a bootable copy of the hard drive anyway?
    No, TM backups aren't directly bootable.  If your internal HD dies, you can restore your backups to a replaced internal HD, or another external HD.  The restored system is bootable.
    if the hard drive died, wouldn't Time Machine be able to restore everything?
    Yes.  The things it doesn't back up are re-created as needed anyway.  See FAQ #14 for details on doing a full restore.

  • Were to find db2 drivers and how to check if it is working

    i have to configure a scenario from db2 to xi to rfc
    let me know were to find the db2 driver and once done how do i check if i have installed the correct driver. is there any sample program through which i can check if the driver is installed

    Hi Amit,
    IF you have already instaled DB2 databse, then you can get the driver, in this location from your DB2 database folder,
    /usr/local/java/db2/lib/db2jdbc.zip
    If you need to install DB2, then I would suggest that you try this link,
    http://www.ibm.com/software/data/db2/
    http://www-128.ibm.com/developerworks/db2/library/techarticle/0203zikopoulos/0203zikopoulos.html
    As DB2 is a Database from IBM, a search in the IBM website can also help you if the above links do not help.

    Hi,
    Like Jaffar said, run statspack is a good thing.
    To check performance, the best way consist to run statspack when your database work well, to have a baseline.
    When you think there is any problem, rerun statspack and compare with your baseline.

  • How to check the BW and BIA systems are up and working fine.

    Hi friends,
    how to check the BW and BIA systems are up and working fine. And also what is ICM, how to check whether it is working properly or not.
    ANd what is name resolution and IP , how to check whether this is running fine.
    regards, balu.

    Hi,
    you can use process monitoring or the alert function in the standalone TREXAdmin tool.
    ICM:

  • How to check whether Output ES is working or not.

    I am able to see Output ES in the services list of the admin console of my server. Please let me know how to check whether this is working or not.
    Regards,
    Shabeer

    LiveCycle ES2 (and LiveCycle ES) ship with three undersold and unadvertised web applications that are VERY useful. Each is referred to as an Installation Verification Sample (or IVS) but they are great testing tools you can use during development and QA. There is
    1) Assembler IVS,
    2) Forms IVS, and
    3) Output IVS
    Output IVS looks like this...
    The pattern for deploying and using all three IVSs is very similar as what I am about to describe for Output IVS. The following directions apply to the JBoss turnkey on Windows.
    1) go to C:\Adobe\Adobe LiveCycle ES2\deploy and locate adobe-output-ivs-jboss.ear
    2) copy adobe-output-ivs-jboss.ear to C:\Adobe\Adobe LiveCycle ES2\jboss\server\lc_turnkey\deploy
    3) if necessary, start LiveCycle
    4) open a browser and go to http://localhost:8080/OutputIVS/
    5) click Check/Change your preferences
    6) add Admin Credentials
    7) click Save
    8) click Test your form designs
    9) Select an .xdp from Form designs
    10) Click Use EJB (or Use Web Service if you feel so inclined) to invoke LiveCycle Output ES2

  • How to check MAxl is running properly or not

    Hi All,
    i am working on ASO cube which has to implement Automation for dimension building and data loading. I am unable to execute even a single sample systax with out error. Is there any specific method to use Maxl in ASO cube or any precautions to be taken in ASO for Maxl scripts.
    I don't know it is a foolish question or not to ask like "how to check the Maxl is working properly or not" bcoz it is raising me doubt by raising error for sample script also.
    please help me out from this issue .
    Regards

    Can you log into Essbase through MaxL interactively.
    If so, can you do it from a script? Something like:
    login username password on servername ;
    exit ;
    If you can't do the first, yup, your MaxL client is hosed or you don't have a valid username/password. Or you don't know the servername.
    If you can't do the latter, perhaps your client (could be the server itself, if you're running it from there) has a pathing issue when running batch files.
    If both work, it is a syntax issue. Now you're just faced with your mistake(s). :) But at least you don't have to spin wheels trying to figure out if MaxL is working or not.
    Regards,
    Cameron Lackpour
    P.S. You might want to try using the MaxL editor in EAS and see if your login code works there. I believe (not sure, but I think so) that EAS has its own flavor of MaxL as I know you can run code there without having the Essbase client installed on a local machine.

  • How to Check WET610N is working?

    I called and spoke to a Cisco representative and they told me all I have to do is get a WET610N and WAP610N in order to get my wireless situation set up.
    We currently have the E3000N (which everyone said was the strongest router, but doesn't even go 300ft) it is connected to our cable modem.
    It sends out it's wireless signal, and the Cisco representative told me if I get the WET610N to act as a wireless bridge, and then the WAP610N to act as a wireless access point we should be able to extend the wireless range.
    I've set up the WET610N and the WAP610N. It claimed that everything was working correctly, that the wireless bridge was set up, etc.
    I created a second SSID and it appeared to work. Then we moved the WET610N and WAP610N to their location in order to extend the range and it stopped working!
    I know for a fact we are not out of the wireless range of the E3000N as I am using it to post this. The second SSID coming from the WAP610N is broadcasting and the signal is strong, but when I try to connect it says it has limited internet access, or no access.
    So is something wrong with the WET610N in receiving the signal? Or is something wrong with the WAP610N? How can I check if they are working? Do I have to reconnect them to the E3000N to check? Is there a surefire way to make sure it all works?

    How you have configured WET and WAP? have you setup a static ip on them or it is configured as dynamic ip? If you have setup a static ip then on your computer open the command prompt window and ping the ip address of the bridge and check if you are getting replies, If you are getting replies then the bridge is configured properly, then you need to check the settings for your AP.
