Hi when I conect with ssh, I can't seem to play files locally even though I use -X or -d. Anyone know why? I'm using Ubuntu 7.10 x86
Thanks

I'm still having no joy with getting anything to open a remote X11
window on my laptop since I changed to Ubuntu from Mandrake.
I'm using ssh to log in to my server (and yes I've tried using ssh -X
but that makes no difference). Once I'm logged in I try to start an
emacs window on the laptop:
server$ echo $DISPLAY
felix:0.0
server$ emacs &
server$ emacs: Cannot connect to X server felix:0.0.
Check the DISPLAY environment variable or use `-d'.
Also use the `xhost' program to verify that it is set to permit
connections from your machine.
[1]+ Exit 1 /usr/bin/emacs -geometry 80x48 -font 9x15
running 'xhost +' on the laptop (and yes, I know it's not that
secure, but I'm relying on the firewall on the server to prevent
anyone from outside logging in via X11)
says:
felix$ xhost +
access control disabled, clients can connect from any host
felix$
I've been looking in the /etc/X11 directory and found Xwrapper.config.
This states that Ubuntu has a security wrapper around the X server.
I have tried changing this from 'allowed_users=console' to
'allowed_users=anyone', ran 'dpkg-reconfigure x11-common'
and logged off and on again, but still no improvement.
Does anyone know anything about this security wrapper?

Hi
During the installation of ubuntu, i was asked to set my username and password. Does this mean that this is the password for the "superuser"?
Every time I log in using this username and password, does this make me the superuser? Does this mean that when i am in the Terminal, i am already at the "root" ?
I am the only person using this computer.
Thanks
bakut

No, that's your user password. You aren't logged in as root, you're logged
in as you. Ubuntu disables root by default and sets the first user created
as allowed to use sudo for all commands. See
https://help.ubuntu.com/community/RootSudo for more info.

Turn on X11 port forwarding on your ssh client and server. The X session
will be port forwarded over the SSH connection which is a more secure
way to run X remotely. The relevant configuration files
are /etc/ssh/ssh_config and /etc/ssh/sshd_config.

Hey,
The username and password you gave were not for the super user. They
are for an ordinary user account. Ubunt uses `sudo` (super-user do) to
allow you to have superuser access when it is needed. For example if you
go to open an administrative task from the menu it will ask for a
password, this is to allow that task to run as the superuser.
cheers,
Owen.

Yes, I also have success with "Desktop Effects" off, but I wanted to be
able to use them. So, at least here, the "sudo pmi action suspend"
continues to work with compiz running.

Hi lu sy,
No, it's not your su, superuser, password. You don't
have a default su account in Ubuntu unless you setup
one. However, the username and password you gave in
the install process allows you default admin and su
privileges via sudo. To get this su privilege you type
sudo before any command needing root privilege and it
will ask for your password before executing the
command, ie., the password you gave for install.
You can always tell, from a CLI, if you are in a user
or root account, by the prompt. A user account has a
"$" at the end of the prompt whereas a root account
ends with a "#".
Remember whenever you log in with your username and
password as set in the install you are logging in as
that user, not root. To be logged in as root you have
to setup a root account and give a different password
which Ubuntu discourages for safety reasons.
Otherwise use the sudo command(man sudo) to gain
temporary root privilege.
HTH,
Leonard Chatagnier

Just finished installing gutsy and up to date. After
bootup and logging into terminal, messages say I have
mail(there should be as there were many messages from
the upgrade that root should get) so I open mutt and
the status bar at bottom say "no mailbox". However,
there are two such mailboxes in /var/mail and
/var/spool/mail.
This is a long standing issue with me as most will
remember and I would like very much to get it resolved
very much so. I elected to use the maintainers conf on
everything so as not to carry over any feisty setup
conf. I still suspect this issue involves elements of
not having a FQDN, Muttrc and main.cf but after much
googling and reading, I haven't a clue what to do.
Would appreciate any help in the solution.
TIA,
