This article mainly introduces "how to use shell to achieve automatic adsl dialing and detect connection status script". In daily operation, I believe many people have doubts about how to use shell to achieve automatic adsl dialing and detect connection status script. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to use shell to achieve automatic adsl dialing and detect connection status script". Next, please follow the editor to study!
Script 1:
The code is as follows:
Cat / root/soft_shell/auto_adsl_1.sh
#! / bin/bash
Gateway= `ifconfig ppp0 | grep P-t-P | cut-f 3-d ":" | cut-f 1-d "" `
Inter= `ifconfig | grep ppp0 | awk'{print $1}'`
Numb2
If [[$inter-eq ppp0]]
Then
/ sbin/adsl-stop
Sleep 10
/ sbin/adsl-start
Sleep 20
Pkgloss= `ping-c4 $gateway | grep 'transm' | awk-print $2}' | awk'{print $1}'`
If [[$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:
The code is as follows:
Cat / root/soft_shell/auto_adsl_2.sh
#! / bin/bash
Gateway= `ifconfig ppp0 | grep P-t-P | cut-f 3-d ":" | cut-f 1-d "" `
Inter= `ifconfig | grep ppp0 | awk'{print $1}'`
Numb2
If [[$inter! = ppp0]]
Then
/ sbin/adsl-start
Sleep 20
Pkgloss= `ping-c4 $gateway | grep 'transm' | awk-print $2}' | awk'{print $1}'`
If [[$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 purpose of script 2 is to check whether adsl dialing is connected.
