I checked the socks.conf of my office machine, I have
something like:

route {
        from: 0.0.0.0/0   to: 10.239.253.0/24 via: IPsocks
port = 180
        protocol: tcp
        proxyprotocol: socks_v4 socks_v5
        method: none

So I would do

	(add-to-list 'tramp-default-proxies-alist
             '(list "MyMachineName" nil "/socks:IPsocks#1080:"))

but, first I do not know, if the syntax is correct and
second my Emacs version 22.1 gives me:

	Symbol's value as variable is void: tramp-default-proxies-alist

I assume that I am still doing something (a lot) wrong!?

Is this a typo?

First, you must load Tramp in order to declare its variables:

(require 'tramp)

Usually, it is done by the autoloader when you access a remote host,
but you want to customize Tramp before.

Then, you have quoted the list, which is wrong. You must write

(add-to-list 'tramp-default-proxies-alist
             (list "MyMachineName" nil "/socks:IPsocks#1080:"))

IPsocks was some kind of IP-number.

I tried it without and with tramp 'required' and without the
quoted list... but  I get:

Debugger entered--Lisp error: (void-variable
tramp-default-proxies-alist)
  add-to-list(tramp-default-proxies-alist
("test.socksify.com" nil "/socks:141.36.72.254#1080:"))
  eval-buffer(#<buffer  *load*> nil "/home/fab/.emacs" nil
t)  ; Reading at buffer position 193
  load-with-code-conversion("/home/fab/.emacs"
"/home/fab/.emacs" t t)
  load("~/.emacs" t t)
  #[nil "\b…¾

(require 'tramp)
(add-to-list 'tramp-default-proxies-alist
             (list "test.socksify.com" nil
"/socks:141.36.72.254#1080:"))

Strange!?

Please check the Tramp version "C-h v tramp-version". It must be a
recent Tramp 2.1.

That's was the problem, but I had no luck with my socksify
yet ... I will contact my admin next week and see, if
he can explain me a bit more about socks.
So far, thanks for your help; I'll keep you informed.

tramp with socksify

[Fabian Braennstroem]

Hi,

I wonder how I can use tramp together with socksify and telnet;
i.e. right I connect with:
/usr/bin/socksify telnet -l username ip-number port

Does anyone know, if and how I can use tramp to open my remote files?
Would be nice!

Regards!
Fabian

Recent Tramp 2.1 supports socksv5 proxies and http tunnels. Check the
manual for gateway methods. Note that you need GNU Emacs 22.1 for this.

It sounds that it would be possible ... unfortunately the part about
the gateway methods is not
as informative as the others, at least I don't get a clue reading it
and google does not help with socksify, telnet
and tramp!?

OK let's try it together. Maybe we can find out in parallel how the
documentation can be approved.

Assume you will connect to test.socksify.com via telnet. Your socksv5
server is bypass.socksify.com:1080 (in fact I don't know neither the
host name nor the port number of their socksv5 server, it is just a
guess).

You need to declare the socksv5 server as proxy:

(add-to-list 'tramp-default-proxies-alist
             (list "test.socksify.com" nil "/socks:bypass.socksify.com#1080:"))

Then you can connect to test.socksify.com simply via "telnet:test.socksify.com".

It is probably my fault, I have never heard anything about socksify...

Maybe I forgot to say, that I use:

socksify telnet -l USERNAME IPaddress portnumber

to connect to the other machine on the terminal. I would assume that
the IPaddress is the socksv server...
I am not able to check right now, because I just started my holidays
for the next two weeks ... than I will check out more.

Thanks!

Should be "/telnet:test.socksify.com:", of course.

Nope. That is the target you want to reach with your telnet command,
as far as I understand socksify. So you would open
"/telnet:USERNAME@IPaddress#portnumber" in your case.

The configuration of `tramp-default-proxies-alist' is equivalent to
what you need to configure in socks.conf for socksify.
