Ping Script
0568 jours
A few minutes ago I completed this little ping script,
for non initiated users.
It first pings the 192.168.1.1
then pings the 192.168.2.1
after that it pings the 8.8.8.8
and finally pings the www.google.com address
Why does it pings 1.1 and 2.1 ?
Because my friend wanted to use it in different areas, ( he his not familiar with the shell ) for example at work 1.1 and home 2.1.
Why does it pings 8.8.8.8 and google.com ?
Similar as above 8.8.8.8 is the DNS of google .. and google.com is just reaching the web
How does it work ? :
Execute the script.sh and it will print out 5 pings to 1.1 and write the result in GREEN / RED and then 5 pings to 2.1 and the result in GREEN / RED
and so one.
The script :
#!/bin/sh GREEN="\\033[1;32m" NORMAL="\\033[0;39m" RED="\\033[1;31m" clear ####################### 1.1 ################ ping -c 5 192.168.1.1 if [ ! "$?" -eq 0 ]; then echo -e "$RED" "ping 1.1 failed" "$NORMAL" else echo -e "$GREEN" "ping 1.1 passed" "$NORMAL" fi ########################## 2.1 ############## ping -c 5 192.168.2.1 if [ ! "$?" -eq 0 ]; then echo -e "$RED" "ping 2.1 failed" "$NORMAL" else echo -e "$GREEN" "ping 2.1 passed" "$NORMAL" fi ########################## 8.8 ############## ping -c 5 8.8.8.8 if [ ! "$?" -eq 0 ]; then echo-e "$RED" "ping 8.8 failed" "$NORMAL" else echo -e "$GREEN" "ping 8.8 passed" "$NORMAL" fi ########################## GOOGLE ############## ping -c 5 www.google.com if [ ! "$?" -eq 0 ]; then echo -e "$RED" "ping google failed" "$NORMAL" else echo -e "$GREEN" "ping google passed" "$NORMAL" fi
So have fun 
How to know my public ip address with bash
0759 jours
this is a little bash script to know your public ip address
this was tested on snow leopard and it works well
it can be use also on linux … i tested it on my ubuntu and it’s also good working
#!/bin/bash
wget http://www.monip.org/ 2> /dev/null
echo "The public ip is :"
perl -ne 'print "$1\n" if m/((\d{1,3}\.){3}\d{1,3})/' < index.html
rm index.html
You can use it when you’r behind a nat … it’s actually good working ( based on http request’s)
