Validate connection to remote host – Sprawdzanie łączności z hostem
- A simple connection test to a remote host…
#!/bin/bash n_sec=2 #ping waits n of seconds REMOTE_HOST_IP=192.168.0.1 ping -c $n_sec $REMOTE_HOST_IP >/dev/null if [ $? -eq 0 ]; then echo "Ping OK" else "Host is not available" fi #END-SCRIPT#
- and the other way, below script will check the connection and after 30 seconds will write the result to root session screen if connection cennot be established, nice small network monitor which can be executed by crontab, for instance.
#!/bin/bash /bin/ping -c1 -W30 192.168.0.1 >/dev/null 2>&1 if [ $? != 0 ]; then write root < /root/noconnect #in this file we write the messages to be displayed fi #END-SCRIPT#
