Dear friends,
I have got a pc install with linux mint 9.I have set up the pc with remote access enable so that I can access it from my ubuntu desktop and window 7 laptop.Each time I switch on the pc,I am unable to access it,will have to restart the pc a few times before I can remote access it.May I know if this is normal or is there a config set up that need to be done so that the remote access is started each time the pc is on.

Attach is an error when trying to log in using remote access(Real VNC Viewer) from window 7 laptop.

Thank you for reply

You mentioned the restarts and so on, but failed to tell us what happens when you enter the keyring password.

Depending on what you need to do with the remote access, ssh and scp might be all you need. They should already be present in Mint.

There is an excellent Windows application callet PuTTY.

Hi frankbell,
Apologies for my late reply.The linux mint desktop I have set it up without a monitor using remote access to control it from my ubuntu system. But each time when I try to log in,access is deny.When I put back the monitor only to see the keyring display.When I put in the password,I will be able to remote access it from my ubuntu system.

Looking forward to your reply
Thank you very much

Is it possible that you have your firewall enabled to start at startup. I've done it and until you give your keyring password to enable the firewall, you cannot access your desktop even through ssh. Or it could be that your Mint 9 is asking for the keyring to connect to the internet/intranet. Unless you've checked available to all users in network manager I think it will ask for permission before connecting every time.

Hi,
How do I check if firewall is enable in Mint 9?Over at Mint PC,I did the below

Remote Desktop Preferences
Sharing
I check "Allow other users to view your desktop"
I check "Allow other users to control your desktop"

Security
I uncheck "You must confirm each access to the machine"
I uncheck "Require the user to enter this password" (No password put)
I uncheck "Configure network automatically to accept connection"

I have two systems at home one is LMDE and the other Mint 10. I've got firestarter as the firewall in both systems, but if you haven't installed than you will have the default ufw firewall. Don't know if it gets enabled by default though. If you have a router you may not even need a firewall, but it's safer to keep one anyway.
Here's what I would do.
Download firestarter and openssh-server on to your Mint 9 machine. Both of them are available in the software manager. Enable firestarter and it would also be good to tick "Launch when I log in"
Get back to your ubuntu machine and connect to your mint 9 one through ssh. You'll get an error, but if you check the mint 9 machine the firewall would have blocked the connection. open firestarter and under events you will see a red coloured one with your ubuntu machines's ip address. Right click on it and click on "Allow connections from source". When next you try connecting via ssh you should get a password prompt. If you are ok with using ssh, you don't even have to do what you did above with the sharing and security.
As for connecting using your windows machine, just download free vncviewer, start it up and put in the ip address of your mint 9 machine. you can connect to your other machine from ubuntu too using vnc, it's just as easy and you don't have to do any of the above with the firewall etc.
I don't know about security though, but I did find an app in the software manager "ssvnc" that uses ssh to connect making the connection secure. Never used it though, although it shouldn't be too different from the normal one.

Hi Inkit,
Sorry for the late reply.I have ssh install in the mint system and is working well.One thing I notice is that whenever I unplug the monitor from the system and switch on the desktop(headless),the remote access is not working.But when the monitor is plug to the system,then remote access is working well.I don't understand.Does remote access need to have a monitor plug in order to work properly?

Looking forward to reply
Thanks

I don't know how the presence or absence of a monitor should make a differenece. The only thing that I can think of is that when you have your monitor attached you're able to see the password prompt for the firewall etc. If you have firestarter enabled it will always ask you for your admin password, even if you have your system configured to login automatically. If you don't you can't enter in the password and so can't have access to your system. Maybe you can try starting it up with a monitor and then disconnecting it to see if it still works?
