Hello.. My company recently changed to a new proxy server and now my gem update commands aren't working. Doing a gem update gives me: Updating installed gems ERROR: While executing gem ... (Zlib::BufError)     buffer error I searched and found the rubysspi gem ([http://rubyforge.org/projects/rubysspi/](http://rubyforge.org/projects/rubysspi/) ). I installed it and configured as per the directions and set my http\_proxy environment var: set http\_proxy=http://192.168.4.3:3128 (I also edited the gem.bat command to automatically include the library -rspa) But now I get: Updating installed gems ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)     bad response Proxy Authentication Required 407 ([http://gems.rubyforge.org/la](http://gems.rubyforge.org/la) test\_specs.4.8) I'm not sure what the problem is or what to do to fix!

Ruby does not support NTLM authentication by default which is what your proxy probably uses. Maybe this will help: [http://rubyforge.org/projects/rubyntlm/](http://rubyforge.org/projects/rubyntlm/) > **···** > > On Dec 10, 2008, at 07:11 AM, Zhoran Tvalve wrote: > > > John T. wrote: > > > > > I was finally able to get it to work by including the username and > > > password in the environment var: > > > > > > HTTP\_PROXY=[http://username:password@192.168.4.4:1234](http://username:password@192.168.4.4:1234) > > > > > > (replace username, password and proxy address/port as necessary) > > > > > > that made it work.

Hm. Not sure. The first one you list below did work for me. I didn't have to include the domain. Try typing the 'env' command to list the environment variables - there is one defined for me: USERDOMAIN=mydomain It should already be set, and I don't know if that's used. Also I did install that rubysspi gem, but am not sure if that's helping or not...
