ECN Unix Support Site

Welcome to UNIX Support. Engineering Computer Network splits software duties into two: the UNIX side and the Windows side. On this page begins a place to look for UNIX software solutions, such as answers to using UNIX platforms such as Solaris, Linux, IRIX and HP-UX, plus, good security practices when using UNIX, Windows, MacOS or the network.


The UNIX support staff consists of five members:

  • J. Nelson Howell, Systems Programmer/Administrator
  • Joseph R. Kline, Unix Systems Administrator
  • James M. Moya, Software Support Services Manager
  • Mark Senn, Systems Programmer
  • Curtis Smith, Senior Systems Analyst/Developer

All ECN software changes and announcements are sent to the syslog mail list.

When sending out announcements about software or security updates, the UNIX support staff may digitally sign the messages before relaying them to the usenet newsgroup purdue.ecn.log. To obtain copies of the staffs' public keys, browse the ECN ftp server:

Help Documents

There are a variety of UNIX help documents available in the ECN Knowledge Base. Click here to go to the UNIX documents.

Source Code

Here's some projects that include source code:

ECN Root Certificate

ECN maintains a single level certificate structure to authenticate web and e-mail services. A root certificate:

signs individual hosts certificates. Then only the root certificate is needed in browser or e-mail applications to authenticate ECN hosts. The ECN root certificate has a fingerprint of:

MD5 Fingerprint=BA:A9:2B:FB:CD:22:9C:99:65:A5:57:2F:E8:A8:14:3D
SHA1 Fingerprint=1C:EB:07:92:00:7B:B0:3A:E9:E2:41:F9:5E:63:A2:6A:19:1C:FE:EA

In Windows 2000, clicking on the lock icon at the bottom of Internet Explorer will show the host certificate. The Certification Path tab should show the host certificate, with the Engineering Computer Network certificate above it. Double-click on the ECN certificate, then go to Details tab, click on Thumbprint and compare the string Thumbprint with the SHA1 Fingerprint above. Also, a certificate revocation list is available.

Remember: ECN makes every attempt to keep the security of the certificates. In no event is ECN liable for any indirect, incidental or consequential damages, or loss of data in connection with the use of these certificates. The purposes of these certificates are for casual assurance of host identity.
