- netcons v 2.0
-
- This is the second version of 'netcons' a script I wrote to give simple listings of current
- Internet connections.
-
- The first version was released only to the PPP under NeXTStep listserv earlier this week. The
- only change in this version is that I have tested it for 5 days, found it to work quite well,
- and added a check for NNTP connections.
-
- 'netcons' basically does 1 of 3 things:
- 1) gives you the IP address of the machine you are on (netcons -I)
- 2) gives you a 'yes' if there are connections and 'no' if
- there are not (netcons)
- 3) gives you a brief summary (in human readable format) of current local
- and remote internet connections.
-
- All of this work is done by parsing the feedback from the command 'netstat'.
-
- These are currently the only types of connections which 'netcons' is smart enough
- to recognize (both incoming and outgoing):
- POP3
- ftp
- login (which is actually 'rlogin' or 'login -r')
- nntp
- telnet
-
- If anyone wants to send me the output of 'netstat' when they are performing some other
- operation (uucp, fax? I dunno, this is all I do, so this is all it does so far).
-
- Eventually I'll use this in my 'pppdown', to check and make sure there are no active
- connections before brining down PPP.
-
- I imagine that this will be most useful to people using dynamic PPP, but it may also be useful
- to those who want an easy way to monitor internet activity.
-
- PLANNED:
- As soon as I figure out how, I want to add checks for Web activity (ie are you loading
- a page right now, etc) but I don't know exactly how to do that yet.
-
- Send me comments/suggestions/whatever
