I'm trying to login remotely to my Ubuntu (12.04) desktop by using NX Client program ( running on Windows 7 laptop). On the Ubuntu box NX server (version 3.5) is configured to use SSH which is also installed on the box.
I was able to login with no issues all these days but since today morning the client is throwing an error and unable to login to the box. Between last night and today morning I have only changed two files - /etc/hosts & /etc/hostname. After the change both files reads as follows
127.0.0.1 localhost
127.0.1.1 name_of_host
Please note that the ubuntu box has LAMP running on it.
I looked at the syslog on the Ubuntu box and this the log message I get
Jul 16 08:50:32 (none) NXSERVER-3.5.0-11[2717]: ERROR: Wrong hostname get from hostname command: hostname

Any help is really appreciated.
I was able to login with no issues all these days but since today morning the client is throwing an error and unable to login to the box. Between last night and today morning I have only changed two files - /etc/hosts & /etc/hostname. After the change both files reads as follows
