On Mac OS X, setting an http proxy means just that: this proxy is used
for http connections (by Carbon/Cocoa apps; command line apps, except
for equivalents of GUI apps such as softwareupdate, nor X11 apps won't
know anything about it).
It is also possible to use http proxies to tunnel arbitrary protocols,
but Mac OS X does not do this.
You can configure it yourself for ssh though. From "man 5 ssh_config":
***
ProxyCommand
Specifies the command to use to connect to the server.
The com-
mand string extends to the end of the line, and is
executed with
[snip]
This directive is useful in conjunction with nc(1) and
its proxy
support. For example, the following directive would
connect via
an HTTP proxy at 192.0.2.0:
ProxyCommand /usr/bin/nc -X connect -x 192.0.2.0:8080
%h %p
***
So create a file $HOME/.ssh/config and add the above line to it
(replace the ip address/port with those of your proxy server).
do i have to configure proxy for the X11 independently?
No, because X11 should be forwarded over your ssh connections. Just
make sure that you use the "-X" and "-Y" parameters.
