Session issues

[hsravan]

Dear All,

I'm new to linux environment. So help me with this forum.
I have two linux machines.. Till yesterday, I have access to those 2 systems through Winscp, VNCServer and Putty.

As I change home owner ship from root to oracle(user), I'm unable to connect through either putty nor Winscp. But I connect through VNC. And also even if I click on services or anyother application in GUI, it displays a dialog box "Unknow error".

Please find me a solution for this.

As I change home owner ship from root to oracle(user),

What do you mean by this statement? What command or commands did you run to do this?

What do you mean by this statement? What command or commands did you run to do this?

I mean when I change home permission's from root user to oracle user. Making "Oracle" user as root on home directory..

# chown -R oracle:dba abc
# chmod -R 777 abc.

From then im unable to access from winscp and putty.. but can connect through vncserver.

Is abc the home path for the user oracle? Show the contents of this command:

 grep oracle /etc/passwd

If abc is your home directory, you definitely don't want to be doing a 'chmod -R 777' on it - that will screw up your SSH config at the least.

Show permissions of oracle's home dir:

ls -ld `awk -F: '$1 ~ /oracle/{print $6}' /etc/passwd`

Also, can you show exactly how you are calling SSH?
