Could you post errors that you got please. All online nodes are running on Ubuntu server. It should work fine.
when i try to send a command to daemon like "pointcoind getinfo" it writes "could not connect to server" (((
Ok, it would take some time to sync the Blockchain, please check with top if the pointcoind process is active. Also check the debug.log to see if it is logging info about block.
Once the wallet has synced the blockchain it will respond to commands.
