I would like the window title of the terminal to reflect the hostname of the current login machine. This shows $HOSTNAME plus the usual stuff by adding the following to your bash profile (~/.profile): <code>export PROMPT_COMMAND='echo -ne "\033]0;${HOSTNAME}: ${PWD/$HOME/~}\007"'</code> Here is a nifty little hack for the Terminal.

I have posted your suggestion to solve an eventual "nolisten" problem with Mac OS X Leopard running X11 Forwarding. Cheers, Thomas Hello again Kerem,

Thank you for your valuable comments and suggestions. I have posted your suggestion to solve an eventual “nolisten” problem with Mac OS X Leopard running X11 Forwarding.

Since you can connect to your X when you manually set DISPLAY over the remote system it means that it listens to TCP connections over your Ethernet adapter. But as you know ssh –Y and –X will set the remote display to localhost:10.0 and since you can not launch remote applications there it seems that your X does not listen localhost (127.0.0.1 interface) As I’ve told I am not familiar with MacOS. I am not sure where you will need to change. But I’ve found this link: http://www.macosxhints.com/article.php?story=20081208062918906 I hope this helps. What I understand is to see that port 6000 is bound to * not the Ethernet address. (I mean “netstat –na” ouutput) Cheers, K. Hi,

The conventional and right way "<code>ssh -X login@remotehost</code>" Great.. things happen! I think I fucked up the sshd_config file somehow. What a relief.. puha!
