How do I use a socks server with cygwin?

How do I use a socks server with cygwin?

[Niklas Morberg]

I sit behind a corporate firewall and I'm looking for a way
to use e.g. cvs from behind the firewall. SOCKS is installed
on the firewall.

When I sit on a standard Unix machine, I would use the
runsocks script to achieve this:

% runsocks cvs up

How would I go about doing this in cygwin?

Hummingbird has a free (as in beer) solution to this problem for Windows
that works for Cygwin too:

    http://www.hummingbird.com/products/nc/socks/install.html

I have been using the above very successfully with the following
applications:

    o Netscape Navigator [1]
    o Microsoft Internet Explorer [1]
    o Netscape Instant Messenger
    o CVS (anonymous pserver)
    o ssh
    o ncftp
    o wget
    o curl
    o dict

[1] However, due to the benefits of a caching web proxy, I recommend
configuring these applications to use such instead of SOCKS, if available.

You're saying that by using the Hummingbird product, you can ssh through 
the firewall?  Can you elaborate how you did this?

Just a quick thought about firewalls and ssh'ing through them.. 

We had a firewall that allowed https-connections, and well, you can
use this to connect to a ssh-server, by telling ssh to use a wrapper
script to fire up the connection, get in touch with me and I can dig
it up.. 

Meanwhile, using a socks server, well basically it should be up to the
application, not cygwin to handle this, so if you find a cvs
supporting socks off you go.. :-)

That's just it -- I normally use 443 as a way to get through firewalls 
with ssh.  But at the company I work for (I'm a consultant), EVERY port 
is locked down or pushed through a socks server.  Hence my need to get a 
functional socks filter...

Font size and color for rxvt

[rotaiv]

Does anyone know how to change the color and font size with rxvt?  I read 
the FAQ and MAN pages and they talk about the font resize button (ALT ->) 
but that does not work.  They also mention configuration files that I do 
not have with my installation of cygwin.

Also, if I use RXVT instead of the CMD.EXE to run bash, what switches 
should I use?

Finally, what values should I use for the TERM and CYGWIN environmental 
variables?

Regards,

rotaiv.

Re: Font size and color for rxvt

[Randall R Schulz]

Rotaiv,

This has now acquired the status of a perennial question, so searching the 
archives will yield several informative messages. Also, if you read the man 
page, then you must not have read it very carefully, because it's quite 
clear about setting the fonts. It won't explain the funkiness with some 
fonts and scaling and whatnot, but the mail messages and some 
experimentation will bring you up to speed with that.

Here's an invocation I use in a Taskbar shortcut:

'D:\cygwin\bin\rxvt.exe -g 120x99+732+0 -bg #000055 -fg #eeeeee -fn "Lucida 
Console-11" -sr -sl 5000 -vb -e /bin/bash --login -i"

Here's another:
"D:\cygwin\bin\rxvt.exe -g 120x91+853+0 -bg #000055 -fg #eeeeee -fn "Andale 
Mono-12" -sr -sl 5000 -vb -e /bin/bash --login -i"

(You'll need a screen in 1600x1200 resolution for these sizes and positions 
to work and fairly good vision, if my coworkers' constant squinting is any 
indication.)

The Andale version crams a lot of text in a given bit of screen real 
estate, but the Andale font is not included with Windows (at least through 
2000, I don't know about XP). It is available by no-cost download from 
Microsoft. You'll find information about this in the mail archives, too.

Good luck.

 From /usr/src/openssh*/contrib/README:

   http://www.imasy.or.jp/~gotoh/connect.c is a Unix and Windows
   ProxyCommand which allows OpenSSH to make connections through a SOCKS5
   or http proxy which supports the CONNECT method (eg. Squid).

Works fone for me.  Compiles OOTB on Cygwin, I put it in 
/usr/local/bin/proxyconnect, and added the following lines to /etc/ssh_config:

   Host machine_that_needs_socks another_such_machine
           ProxyCommand proxyconnect -R local -S socks.server.domain.tld %h %p

HTH,

Yes.

> Can you elaborate how you did this?

Once the Hummingbird SOCKS proxy software is installed, all that you need
to do is create a socks.cnf file.  See attached for a sample.  This it!
You are done!  It's that easy!

If you are looking for just a ssh/SOCKS solution then try the following:

    http://www.imasy.or.jp/~gotoh/ssh/connect.c
    
This is what I used before I found the generic Hummingbird solution.

BTW, Shun-ichi GOTO has a cvs-socks solution (if you can read Japanese)
at:

    http://www.imasy.or.jp/~gotoh/ssh/

Sorry, I disagree.  Why modify every application (of interest) when one
can use a "shim" like Hummingbird under Windows, tsocks under Linux, etc.?
The duplicated effort doesn't seem to make sense.

Thanks to the @Home to Comcast conversion, I have obtained empirical
evidence that Shun-ichi GOTO's ssh specific solution is *much* better
than the Hummingbird generic SOCKS solution (at least for ssh).

Even though I use the Hummingbird solution for everything else,
I was still using connect because I perceived it to be faster, have
less latency, and be more robust.  Although, given the generally poor
performance of my company's SOCKS server, it was hard to be sure.

I forgot to change my .ssh/config file to reflect my new IP address due
to the @Home conversion.  Hence, for the last few days I was unknowingly
using Hummingbird instead of connect.  I was very unhappy with the
horrible performance.  Then I realized that I was not using connect.
Once I fixed my .ssh/config file and started using connect again, my
SOCKS/ssh performance returned to the pre-conversion levels.

I would like to publicly thank Shun-ichi GOTO for providing this
valuable tool.
