ssh as SOCKS server

ssh as SOCKS server

[GregHolmes]

I'm trying out the new Dynamic port forwarding
feature of ssh, testing on the local machine.
My tired brain must be missing something.

I initiate the connection:

 ssh -vvv -D8000 localhost

enter my passphrase, and successfully begin a session.

Now I use a browser configured to use a SOCKS4
proxy at port 8000.  I try to load a URL and get
some repetitive blocks of debug messages, ending
with:


debug3: channel_close_fds: channel 2: r 8 w 8 e -1
debug1: Connection to port 8000 forwarding to socks4 port 0 requested.
debug1: fd 8 setting O_NONBLOCK
debug2: fd 8 is O_NONBLOCK
debug1: channel 2: new [dynamic-tcpip]
debug2: channel 2: pre_dynamic: have 0
debug2: channel 2: pre_dynamic: have 496
debug1: channel 2: zombie
debug1: channel 2: garbage collecting
debug1: channel_free: channel 2: dynamic-tcpip, nchannels 3
debug3: channel_free: status: The following connections are open:
  #1 client-session (t4 r0 i1/0 o16/0 fd 5/6)

debug3: channel_close_fds: channel 2: r 8 w 8 e -1
----
The page, needless to say, does not load.

It must be something obvious; what could I be missing?
Something to do with doing it on localhost?

Thanks,

Greg H.

I tried same setting and get same message.
So I change proxy setting of browser (I'm using IE6) as
setting SOCKS4 as localhost / 8000 and other entries 
as ALL EMPTY. Then I succeeded.

Is this help you?

Of course, you should be able to resolve hostname on localhost.
Dynamic forwarding support only SOCKS protocol version 4 (not 4a).

Yes!  That was it.  I had left other entries filled
in (slaps forehead).

Now if I could just figure out why sshd today refuses 
remote connections, with no change to sshd_config ... 
aren't computers fun ;)?

Thanks,
