Instructions for using Greenpass Guest
Network Authentication/Authorization
Demo:
Control of network use is important, drive by networking is
easy
wireless traffic can be captured easily, encryption is only
defense
Can delegate to any certificate, will use Papyrus today
Guest should try "Dartmouth User" and should fail
to get a connection
Guest can connect to "GreenPass test" but can only
connect to Greenpass Web Server
Have Guest use previously acquired Papyrus cert first,
Guest goes through steps 1 through 5
Delegator goes through steps 2 through 7
Guest continues steps 6 through 8
Issues:
1. If generated cert from Papyrus in Win IE, may need to
export and reimport
2. On Win, if machine has not used 802.1x connection
previously, may need to use cert already known to RADIUS
3. Mac 802.1x frequently fails to authenticate, fingerprint
mismatch
Guest User
- on Win turn on TLS (IE
->Tools->Internet Options->Advanced, Security section)
- configure wireless connection
- Windows: http://drwatson.dartmouth.edu/cgi-bin/wiki.pl?WindowsGuestAccessInstructions
- Mac: http://drwatson.dartmouth.edu/cgi-bin/wiki.pl?EapTls
- Setupadd SSID for "GreenPass Test"
which is broadcast (note different Cap)
- accept warning that WEP is not available on
Win
- connect to any web page (reroutes to
Greenpass "grandcentral" on dupin.Dartmouth.edu)
- use existing Papyrus cert (SSL)
- Get a "delegator" to authorize you
for a SPKI delegation cert (need code number)
- install Greenpass CA root cert http://www.dartmouth.edu/~deploypki/summit04/GreenpassCA.cer
- accept Greenpass server cert, self signed
with name= localhost.localdomain
- configure wireless connection
- add SSID for "Dartmouth User"
- for Win turn on WEP, enable 802.1x with
smartcard or certificate
- Accept server certs
- Greenpass CA root
- Greenpass RADIUS Server
- This should continue to work until the
expiration of the delegation cert
- Disconnect, reconnect shows delegation
persists
[Note: To try another
cert, visit Greenpass "Grand Central" to clear the browser cookie
you can also revisit
grandcentral with same cert introduced with different browser, which will
restore cookies]
Delegation
- To Delegate, you need to have a delegation
certificate with the further delegation option turned on
- Get one from someone who can already
delegate
- (a delegator gets extra options on his
"Grand Central" web page)
- From any network connection, open a web
connection with dupin.dartmouth.edu
- Look up guest X.509 cert (use code number,
choose correct names of person and organization if duplicates)
- Compare graphic fingerprint
- Delegator selects p12 file with his private
key for Java applet (not using keystore)
- Issues SPKI delegation cert
- Tell guest to continue, verifies delegation
present, then needs to change SSID
