TCP/IP Network Administration

Craig Hunt has worked with computer systems for the last 25 years. He spent the first few years after receiving his B.A. from American University running an outdoor camp for inner-city kids, but the call of the computer was stronger than the call of the wild. Craig went to work for the federal government as a programmer and then as a systems programmer. He left the government to work for Honeywell on the WWMCCS network in the days before TCP/IP, back when the network used NCP. After Honeywell, Craig went to work for the National Institute of Standards and Technology. He's still there today and currently leads the Advanced Network Technologies Division. Craig is a member of the Federal Networking Council, the Large Scale Network Working Group, and the Next Generation Internet Implementation Team. He taught a course on TCP/IP network administration at Montgomery College in the 1980s and currently teaches a tutorial on the subject at Networld+Interop. In addition to TCP/IP Network Administration, he wrote Networking Personal Computers with TCP/IP and Appendix C of Building Internet Firewalls. He is currently working on a version of TCP/IP Network Administration for Windows NT.
