24 | ;;; Commentary: | |
c2e6c8d1 | 25 | |
8749abea GM |
26 | ;; |
27 | ;; There are three main areas of functionality: | |
ddb62bf1 | 28 | ;; |
8749abea GM |
29 | ;; * Wrap common network utility programs (ping, traceroute, netstat, |
30 | ;; nslookup, arp, route). Note that these wrappers are of the diagnostic | |
31 | ;; functions of these programs only. | |
ddb62bf1 | 32 | ;; |
8749abea | 33 | ;; * Implement some very basic protocols in Emacs Lisp (finger and whois) |
ddb62bf1 | 34 | ;; |
8749abea GM |
35 | ;; * Support connections to HOST/PORT, generally for debugging and the like. |
36 | ;; In other words, for doing much the same thing as "telnet HOST PORT", and | |
37 | ;; then typing commands. | |
38 | ;; | |
39 | ;; PATHS | |
40 | ;; | |
41 | ;; On some systems, some of these programs are not in normal user path, | |
ddb62bf1 | 42 | ;; but rather in /sbin, /usr/sbin, and so on. |
