my problem was the following:

H:\>gem search bla --remote

\*\*\* REMOTE GEMS \*\*\*  
ERROR: While executing gem … (Errno::EBADF)  
Bad file descriptor - connect(2)

a long time i could not figure out, why this happens - though i had  
the intention, it must be, because i only can go thru a proxy to the i-  
net. so, here is finally the solution, if you suffer the same  
circumstances.

1. find out, what your proxy url is (in your functioning browsers  
options you will find something like a [sol.org](http://terra.sol.org/proxy.pac);  
donwload this, open in an editor an find your proxy-server url)

2. assuming your proxys url is: [http://terra.sol.proxy.org:8080](http://terra.sol.proxy.org:8080), set  
an environment variable called http\_proxy to that url:

open a shell/command-window an do:

REALOS\> export http\_proxy=[http://terra.sol.proxy.org:8080](http://terra.sol.proxy.org:8080)  
NOOS\> set http\_proxy=[http://terra.sol.proxy.org:8080](http://terra.sol.proxy.org:8080)  
ANYOS\> gem install fxri

thats it

have fun!

Does this work for you:

gem query --remote --name-matches doom -p  
[http://terra.sol.proxy.org:8080](http://terra.sol.proxy.org:8080)  
where:  
“[http://terra.sol.proxy.org:8080](http://terra.sol.proxy.org:8080)” is :

I took it from here:  
[http://docs.rubygems.org/read/book/1](http://docs.rubygems.org/read/book/1)

and:  
[http://docs.rubygems.org/read/chapter/13#page51](http://docs.rubygems.org/read/chapter/13#page51)

To install gems behind a proxy server just append at the end " -p  
[http://proxy.myserver.lan:8080](http://proxy.myserver.lan:8080)",  
where proxy.myserver.lan is your proxy address (check this from your  
browser settings).

For example to install the “rails” gem behind  
“[http://proxy.myserver.lan:8080](http://proxy.myserver.lan:8080)” i’ll use:  
##########

# gem install rails -p [http://proxy.myserver.lan](http://proxy.myserver.lan)
