c2e6c8d1 | 28 | |
8749abea GM |
29 | ;; |
30 | ;; There are three main areas of functionality: | |
ddb62bf1 | 31 | ;; |
8749abea GM |
32 | ;; * Wrap common network utility programs (ping, traceroute, netstat, |
33 | ;; nslookup, arp, route). Note that these wrappers are of the diagnostic | |
34 | ;; functions of these programs only. | |
ddb62bf1 | 35 | ;; |
8749abea | 36 | ;; * Implement some very basic protocols in Emacs Lisp (finger and whois) |
ddb62bf1 | 37 | ;; |
8749abea GM |
38 | ;; * Support connections to HOST/PORT, generally for debugging and the like. |
39 | ;; In other words, for doing much the same thing as "telnet HOST PORT", and | |
40 | ;; then typing commands. | |
41 | ;; | |
42 | ;; PATHS | |
43 | ;; | |
44 | ;; On some systems, some of these programs are not in normal user path, | |
ddb62bf1 | 45 | ;; but rather in /sbin, /usr/sbin, and so on. |
