<p>The firewall I'm behind is running Microsoft ISA server in NTLM-only mode. Hash anyone have success getting their Ruby gems to install/update via Ruby SSPI gem or other method?</p>

<p>... or am I just being lazy?</p>

<p>Note: rubysspi-1.2.4 does not work.</p>

<p>This also works for "igem", part of the IronRuby project</p>

A workaround is to install
http://web.archive.org/web/20060913093359/http://apserver.sourceforge.net:80/
on your local machine, configure it and run gems through this proxy.
Install: Just download apserver 097 (and not the experimental 098!) and unpack.
Configure: Edit the server.cfg file and put the values for your MS proxy in
```
PARENT_PROXY
```
and
```
PARENT_PROXY_PORT
```
. Enter the values for DOMAIN and USER. Leave PASSWORD blank (nothing after the colon) – you will be prompted when launching it.
Run apserver:
```
cd aps097; python main.py
```
Run Gems:
```
gem install—http-proxy http://localhost:5865/ library
```
