Shell realizes automatic ADSL dialing and detects connection status script sharing _linux Shell

Today, my company colleagues to my entire ADSL automatic redial shell, and detect whether connected to, so as to ensure that the internal test server does not drop the net, OK, I sent the script below.

System: CentOS 5.x

Script 1:

Copy Code code as follows:

cat/root/soft_shell/auto_adsl_1.sh
#!/bin/bash
Gateway= ' ifconfig ppp0 |grep p-t-p| Cut-f ":" |cut-f 1-d ""
Inter= ' ifconfig |grep Ppp0|awk ' {print $} '
n=2
if [[$inter-eq Ppp0]]
Then
/sbin/adsl-stop
Sleep 10
/sbin/adsl-start
Sleep 20
Pkgloss= ' ping-c4 $gateway |grep ' transm ' |awk-f ', ' {print $} ' |awk ' {print '} '
if [[$pkgloss-lt $N]]
Then
echo "' Date +%y-%m-%d/%t ' The network is not stable" >>/root/adsl.txt
Else
echo "' Date +%y-%m-%d/%t ' The network is normal" >>/root/adsl.txt
Fi
Fi

Script 2:

Copy Code code as follows:

cat/root/soft_shell/auto_adsl_2.sh
#!/bin/bash
Gateway= ' ifconfig ppp0 |grep p-t-p| Cut-f ":" |cut-f 1-d ""
Inter= ' ifconfig |grep Ppp0|awk ' {print $} '
n=2
if [[$inter!= Ppp0]]
Then
/sbin/adsl-start
Sleep 20
Pkgloss= ' ping-c4 $gateway |grep ' transm ' |awk-f ', ' {print $} ' |awk ' {print '} '
if [[$pkgloss-lt $N]]
Then
echo "' Date +%y-%m-%d/%t ' The network is not stable" >>/root/adsl.txt
Else
echo "' Date +%y-%m-%d/%t ' The network is normal" >>/root/adsl.txt
Fi
Fi

PS: the function of script 2 is to detect whether ADSL dialing is connected.
