[SOLVED] I want to run firefox from SSH

Raakh5 · 04-24-2012, 08:07 AM

Hello,

I have dedicated server and have root access via SSH. I want to use firefox browser from our server. I used this command

Code:

ssh -X root@myserver.com -p 22

Provided password and then:

Code:

# firefox &
[1] 20518
[root@myserver ~]# -bash: firefox: command not found
]# -bash: firefox: command not found
www.yahoo.com
-bash: www.yahoo.com: command not found
[1]+  Exit 127                firefox

Thanks & best regards

Right, so you haven't got firefox installed..?

If you believe it is installed, then running "locate firefox" should turn up a location where the binary is found, but it really should be on your path already.

and port 22 is a default, there's no need to specify it on the command line.

I want to run it on my computer desktop and I have it on my PC not on my dedicated server

Thanks for replying

good for you.

clearly you have to have firefox installed on the system you are trying to execute it on.

I followed this link to install the firefox http://www.brunolinux.com/03-Install..._in_Linux.html and it displays firefox installed
# ls

Code:

application.ini             jsloader          libsoftokn3.so
blocklist.xml               libfreebl3.chk    libssl3.so
chrome                      libfreebl3.so     libxpcom.so
chrome.manifest             libmozalloc.so    libxul.so

icons                       libsoftokn3.chk   updater.ini

Now I tried again:

Code:

firefox]# /usr/local/bin/firefox/firefox
Error: no display specified

right so from wherever that directory is just run "./firefox"

Raakh5 · 04-24-2012, 08:52 AM

Code:

# ./firefox
Error: no display specified
[root@myserver firefox]# ./firefox www.yahoo.com
Error: no display specified

don't log into a server as root. don't run X applications as root, especially not something like a web browser, when there is no benefit ever from doing so.

For the lack of a DISPLAY setting, in my experience that tends to relate to not having the Xauthority set up correctly, and generally from not having xauth and associated libraries installed on the remote system. On CentOS / RedHat etc, this is the xorg-x11-xauth package.

Raakh5 · 04-24-2012, 09:05 AM

Code:

vi /etc/ssh/sshd_config
#X11Forwarding no
X11Forwarding yes

What else I can check?

Thanks for favorable replies

In addition to what acid_kewpie posted, you also have to configure your SSH server to allow X-forwarding.

EDIT: OK, I was to late with that.

Raakh5 · 04-24-2012, 09:09 AM

I just checked the option in my SSH client Tunnel X11 Connections and restarted the SSH client. Now it shown the following message:

Code:

/usr/bin/xauth:  creating new authority file /root/.Xauthority

# ./firefox
X connection to localhost:10.0 broken (explicit kill or server shutdown).
The application 'firefox' lost its connection to the display localhost:10.0;
most likely the X server was shut down or you killed/destroyed
the application.

you "checked the option"? Are you using an SSH command line or not? please clarify this... if this is PuTTY or Terraterm or suchlike on windows, then you need an X server on your local machine to use.

this link should help setting up your X11 Forwarding. also as has been mentioned please do not log into your server running root. just ssh -X user@IP that will be plenty powerful enough to run firefox remote.

you can always use xeyes to test your X11 forwarding too. once your ssh -X is connected (AS USER) you can type xeyes and you should get a pair of eyes on your local desktop that will follow your mouse around the screen.

If that works, then your X11 Forwarding is working.

This is a Windows program. To use X-forwarding you need a X-server to actually forward to. Windows doesn't have one by default, so you need to install one, for example Xming or Cygwin/X.
