Re: [newbie] How to hard reset a modem from command line???

2002-06-30 Thread Steve Jeppesen 

Check out this guys page.  He has created scripts to do some of what 
you suggested - only for the Linux Router Project.
Not too sure if they work for anything outside of LRP.

Good Luck!

 Hi guys,
 
 I am writing a script to run on one of my permanently connected dialup
 boxes.. it will run every 60 minuites as a crontab..
 
 The two things I am not sure about.. if I want to issue a hard reset to the
 modem.. how can I do that from a shell script???
 
 Also, what should I do to physically test if a connection is functioning
 properly? I could try pinging a dns server somewhere and capture the result,
 grep it or something, but there must be an easier way.. any ideas?
 (traceroute maybe?)
 
 I am gonna add alot more to the script, I want it to test the connection 5
 times or more before it assumes its not working.
 and I want the script to count how many times it issues ifup ppp0 and not
 do it more then 5 times an hour..
 
 anyone feel like jumping in with some suggestions???   :-)
 
 
 
 
 Here is what I have so far:
 
 #!/bin/sh
 
   # Set some variables.
 IFCONFIG = `which ifconfig`
 EXTERNAL = ppp0
 
   # Test if ppp0 is ip:
 if [ ! -z `$IFCONFIG $EXTERNAL 2/dev/null | grep UP` ];
   then
   # Interface ppp0 is up,
   # now see if it is working properly.
   # try contacting a site. ping? traceroute? other?
   # Yet to do that.. wondering what the best method is...
 
   else
   # ppp0 is down.
   # Hard reset the modem. (how?)
   # Start the ppp0 connection.
   ifup ppp0
 
 fi
 
 
 Thats a long way from finished.. I want the scritp to test the connection 5
 times or more.. (I mean try connecting to an external src) before it assumes
 the connection isn't working properly, its a dialup machine, so if its
 mailing a big file or something, it might not respond for a while.. so I
 don't want to assume that one test is definative.
 
 
 Kindest regards
