iWeb Access Troubleshooting Notes: (as of 7/22/2002)
If you are having trouble accessing the School's Internal web (the iWeb), there could be
several possible reasons:
In order to provide greater security for the School's Intranet, the URL prefix has
been changed to "HTTPS:" instead of "HTTP:"
Therefore, the base URL is now HTTPS://stoop.vetmed.ucdavis.edu/secure/. If
you have any browser bookmarks set to pages within the Intranet, you will need to change
or replace them accordingly.
KERBEROS LOGIN DIFFICULTIES:
If you should have access to this site, but don't know your UCD LoginID and Kerberos
password, go to UCD's Mothra
website. New Staff and Faculty can expect a delay of a week to 10 days before their
Kerberos information appears in our database and allows authentication. If you still need
help, contact your departmental computer-support person.
You may get a message like this one: "Netscape and this server cannot communicate
securely because they have no common encryption algorithm(s)." You may see a similar
message when using Internet Explorer, or no response at all.
Solution: Older browser versions do not have the security level (128-bit
encryption) that is required to protect the confidential material contained in the
iWeb. The following notes should help in upgrading:
- Determine your current encryption level:
Upgrade your Browser:
- Internet Explorer -- Go to "Help" --> "About..." Look for
"Cipher Strength = 128 bit") If it does not say "128 bit" then you need to upgrade.
- Netscape -- In Navigator or Communicator, go to the Help menu and select
"About Navigator (or Communicator)". Look for the section that reads "Contains
encryption software from RSA Data Security, Inc". If the next paragraph says "This
version supports U.S. security", that means you have 128-bit security. If it says
you have International security, that means you have 40-bit security and you need to upgrade.
For Netscape, you can also find this information by typing (or copying) the following line into
the Netsite, or Location line:
Press Enter. The browser will display a string that identifies your browser to Web
sites. It will read something like:
- Netscape 4.x: -- "Mozilla/4.06 [en] (WinNT; U)"
"Mozilla/x.xx" is the version of the browser.
"[en]" is the language (i.e. "[en]" means "English").
The first part of the display in the parenthesis is your operating system
(i.e. WinNT means "Windows NT")
The last character is your security grade. U is US, 128-bit and I is International,
- Netscape 6.x: "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; m18) Gecko/20010131 Netscape6/6.01"
Look for "en-US".
- Internet Explorer
- Open Internet Explorer.
- Choose Tools --> Windows Update.
- The Microsoft site will then scan for needed updates including a newer version
of Internet Explorer. (and you might as well install the security and critical
updates as well)
- Go to the Netscape FTP download site for version 4.79, or
- Go to the Netscape Website for version 6.2.
