remote ssh can login, but xmanager/xstart or xdmcp failed
location: ubuntuforums.com - date: August 28, 2014
I have a problem to connect to the Ubuntu desktop by Xmanager/xstart or xdmcp.
My client: Windows 7/64bits, Xmanager 4.0
My remote Ubuntu: Ubuntu 14.04.1/64bits, with desktop/gnome, default login gdm--> gnome desktop
I can normally operate the Ubuntu OS locally, including gdm login and gnome desktop.
When I try to connect from Windows client (Xmanager, xstart or xdmcp), it failed. The error message of the Xmanager is (seems that no useful info, I can’t understand.):
[11:10:14] An X11 channel (id=12) has opened.

I can't change password or reenable login password in Pinguy
location: ubuntuforums.com - date: March 17, 2013
I'm a linux beginner. I recently installed Pinguy and am reasonably impressed so far, apart from some small issues. First, I decided to disable the log in password for faster logging on, but then I wanted to re-enable it in system settings > user accounts > automatic login > off. But, regardless of whether it is "on" or "off", I still log in automatically. Any ideas? Also, I wanted to change my password, which I did in Terminal > sudo passwd root > enter new unix password etc. And I get the message: password updated successfully. But I find that my password hasn't actually changed - the old one still works - the new one doesn't. Any help really appreciated.
Can’t start Xserver in remote ssh session – X11 forwarding problem ?
location: ubuntuforums.com - date: November 29, 2009
I’ve recently loaded Ubuntu 9.1 server and installed the desktop.
I have a Radeon HD 2600 PRO video card and I managed to get the GUI working after installing the latest Catalyst 9.10 drivers (ati-driver-installer-9-10-x86.x86_64.run) and
following the guidance of http://wiki.cchtml.com/index.php/Ubu...allation_Guide.
Everything apparently works as it should on the server. The desktop is displayed as expected and all apps work.
However, I want to run a secure remote desktop from my Acer 8930 laptop using Windows Vista Home Premium within my local network.
Following the advice in http://digitizor.com/2009/03/01/how-...dows-over-ssh/ I have loaded Xming and putty on the client and openssh-server on the server.
I can use putty to open a ssh terminal session and successfully logon.
My problems start when I “startx -- :1”.
My log is as follows:

Ubuntu server 12.04 Networking Can ssh to server but cannot ping from server
location: ubuntuforums.com - date: September 27, 2013
I have Ubuntu server on some x86 hardware, and the networking is behaving strangely.
Router 192.168.69.1 / 24 - Serving DHCP
Server 192.168.69.69 / 24 - Serving https (80, 8080, 32400), ssh, NFS
Client 192.168.69.108 / 24 - Ubuntu desktop version
From the client I can get to the internet using Google's DNS (126.96.36.199).
Server used to be DNS, but I uninstalled bind9. Server also does NFS, Plex media, http (port 80) and Tomcat (8080).
From the client (any client, as well), I can ssh to the server, ping the server (and router) and can access all ports and services (NFS, Plex, http and tomcat http). I can login to 443 on the router, too, and it's only serving https.
From the server, I can ping the client.
However, I cannot ping the router or get to the internet. I have set the resolv.conf on the server to use google (188.8.131.52) just like the client, and DNS does not work.
The only entries in the host server's hosts files include loopback and the local host.

Can not forward X11 on remote SSH enabled web server.
location: ubuntuforums.com - date: September 15, 2009
I have recently bought a hosting plan which offers remote SSH. SSH and SSHFS work fine but I am unable to use X11 forwarding, which I would like for running X11 applications on my remote web server.
I established first that the web server had no support for X11:
./xeyes: error while loading shared libraries: libXmu.so.6: cannot open shared object file: No such file or directory
I fixed this by copying my libXmu.so.6 library file to my web server's home directory and running:
It then gave me the message:
Error: Can't open display:
I discovered that the $DISPLAY environment variable is not set, despite me calling SSH with the -X (X11 forwarding over SSH) flag.
How can I set up secure X11 forwarding over SSH?
[SOLVED] Unable to remote ssh login (permission denied)
location: linuxquestions.com - date: June 13, 2013
Im using RHEL 6. I have setup two user accounts as below:
1. john (home dir: /home/john)
2. robert (home dir: /home/john/robert)
After I setup both account, I’ve no problem to login using john account from remote terminal but login using robert was failed with error message ‘permission denied’.
This only happened when I used remote terminal to login but if used switch user (su –l robert) internally from the server which the user account robert was created, I managed to login.
My early assumption was this error occurred due to home dir of robert which was setup under john home dir. Unfortunately changing the permission of home dir also didn’t give any helps.
And fyi, I have no problem to login using other user accounts including root as these account home directories are independently setup unlike john and robert accounts.
I wonder if anyone has encountered the same issue when setting up such users account/home directories?
can ssh into root but not user, help!
location: ubuntuforums.com - date: April 22, 2011
Having trouble adding a regular user with ssh access on Hardy 8.04. I can ssh into root, but not into the newly created regular user with the same ~/.ssh/authorized_keys
AllowUsers user root
and ~user/.ssh and ~user/.ssh/authorized_keys are chmod 600 and chown user:user
ssh user from client results in
Permission denied (publickey).
Could someone please enlighten me what could be preventing ssh login to ~user? And yes I would like to disable root ssh access, but it would be nice to be able to ssh into user first
