Re: [CentOS] remote ssh to machine how display firefox
I've looked over the man page for `ssh' and `ssh_config' on several systems and I think people have it backwards. The pages I read indicate that `-X' is more secure than `-Y'. Under the `-X' part on several systems I have access to says: "For this reason, X11 forwarding is subjected to X11 SECURITY extension restrictions by default." The `-Y' says: "Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls." I would think being subjected to security controls would be more secure than not being subjected to them. -- Brent L. Bates (UNIX Sys. Admin.)

One would hope so, assuming authorized_keys and proper pass phrases (but then putty and others allow this from the Microsoft Virus, Windows and I don't trust anything coming from Windows). On the few systems where we permit ssh authentication with user name and password, access is tightly controlled via tcp_wrappers to specific IP addresses. Recently we have been using OpenVPN to allow secure access from remote users which makes restricting ssh access easier when people are roaming so can't be easily identified by IP address.

Re: [CentOS] remote ssh to machine how display firefox
Caveat to using firefox over X11... you will sometimes get corrupted images and icons. This is because firefox (and many other X11 applications) use shared memory to store images. The corruption comes because your local X11 server cant see that memory location and will write whatever it can get to fit that space. There are supposedly ways to fix this.. but I don't know of them off hand. -- Stephen J Smoogen. -- CSIRT/Linux System Administrator How far that little candle throws his beams!

That's a good one. You can take it further (if you have more than one site/port to connect to) - install a proxy on the remote machine (e.g. "squid" or maybe apache's mod_proxy) and forward a tunnel to it as you describe then setup localhost:8080 as your proxy (firefox extensions can allow you to use this proxy only for certain sites).

Then consider: 1. turning on maximum compression ("-C" switch to ssh). 2. If you can switch to VNC or NX then do it, apparently it works better than X11 over long distances (and from the docs I understand it's possible to have VNC/NX for one window, no need to setup an entire desktop for that). --Amos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

First - make sure you have "xauth" installed on the remote machine. With CenttOS 5 it comes in xorg-x11-xauth. Ssh needs it to pass over the x11 authentication cookies (e.g. I don't install X environment on my servers so I have to remember to install this package separately). Secondly - when you login through SSH, type "echo $DISPLAY" and see if you get anything - if not then X11 isn't being forwarded yet. Also I hope you start ssh after having X11 environment started on your local machine and from a shell which has $DISPLAY set correctly *locally*. When all these tests are passed I usually try to run a basic X11 program like "xlogo" but you might not have it so just try to run firefox again and see what happens. --Amos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] remote ssh to machine how display firefox
I can ssh into a remote machine. I can start X on that machine with startx No need to start X on the remote machine. You need to do "ssh -X " so that X is forwarded (back to the machine that you ssh'ed from). Make sure that "X11Forwarding yes" is set in the /etc/ ssh/sshd_config file (restart the sshd if it was not). Then you can simply type "firefox &" and it will appear on the machine you started the ssh from (assuming of course that a X server is running locally). This of course works for any X11 application, not just Firefox. Alfred ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
