I had a problem where my pppoe connection was lost two or three times a day..
Since I use it to host works stuff. I needed it to be able to reconnect itself.. so I wrote this script.. it needs a few perl modules installed.. but it works great.. Its rough, but it works.. It goes and checks if it can access both google and yahoo and if it can't get one.. (it doesn't need to be able to get both.) it will restart the connection and email you to tell you it did.. copy everything from the start to the end lines.. and put it in a file.. put it in /usr/bin or similiar.. and make it executable.. then put an entry in contab like this: -0,10,20,30,40,50 * * * * /usr/sbin/monitor_connection >/dev/null That will run the script every ten minutes., and fix the connection if it goes down.. I have another version that monitors a dialup connection on another box.. ########### START OF SCRIPT ################ #!/usr/bin/perl use LWP::UserAgent; use HTTP::Request::Common qw(GET); use MIME::Lite; my $url = 'http://www.yahoo.com'; my $url2 = 'http://www.google.com'; my @email_address = ('[EMAIL PROTECTED]'); my $SMTP_server = '127.0.0.1'; my $response = LWP::UserAgent->new(env_proxy => 1)->simple_request(GET $url); unless ($response->is_success) sleep 15; my $response2 = LWP::UserAgent->new(env_proxy => 1)->simple_request(GET $url2); Bunless ($response2->is_success) { our $date = &get_date; my $message_txt = "ADSL connection was down and was restarted at $date"; system('/usr/sbin/adsl-stop'); sleep 5; system('/usr/bin/killall -9 adsl-connect'); system('/usr/bin/killall -9 pppd'); sleep 5; system('/usr/sbin/adsl-start'); foreach my $mailer (@email_address) { &mail_data('[EMAIL PROTECTED]',"$mailer", "ADSL WARNING! $date", "$message } }# end of unless2 } # end of unless1 #email and date subs follow. sub mail_data { # usage: &mail_data("mail from address","Mail to address", "subject", "message_txt"); my $from_address = shift; my $to_address = shift; my $subject = shift; my $message_txt = shift; # Start the email body details. my $email_msg = MIME::Lite->new( From => $from_address, To => $to_address, #Cc => '[EMAIL PROTECTED], [EMAIL PROTECTED]', Subject => $subject, Type =>'TEXT', Data => $message_txt ); $email_msg->send('smtp', "$SMTP_server"); } # end of mail_data; sub get_date { my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst,$date); my @days = ('Sunday','Monday','Tuesday','Wednesday','Thursday', 'Friday','Saturday'); my @months = ('January','February','March','April','May','June','July','August','Septembe r','Oc ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time); if ($hour < 10) { $hour = "0$hour"; } if ($min < 10) { $min = "0$min"; } if ($sec < 10) { $sec = "0$sec"; } $year += 1900; $date = "$days[$wday], $months[$mon] $mday, $year at $hour\:$min\:$sec"; return $date; } exit(0); #################### END OF SCRIPT ################################### -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Anne Wilson Sent: Saturday, 14 December 2002 9:35 PM To: [EMAIL PROTECTED] Subject: Re: [newbie] Linux installation & Router Advice On Friday 13 Dec 2002 10:18 pm, FemmeFatale wrote: > All I'm asking is there any special things I need to know when installing > linux behind a router? > > I bought one recently, works great with the windows installs...

The changeover from shared connection to PPPoE was painless, and I have seen no problems that relate to the router issue. When I upgraded to 9.0 no problems emerged either. Maybe I'm missing something, but it seems on my experience to be a non-issue. HTH Anne
