Validate connection to remote host – Sprawdzanie łączności z hostem
A simple script to test connection 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#
Below script will check the connection, if connection cannot be established for 30 seconds it will write results to root session screen. Very nice and small network monitor tool, which can be executed by e.g. a crontab.
#!/bin/bash /bin/ping -c1 -W30 192.168.0.1 > /dev/null 2>&1 if [ $? != 0 ]; then write root < /root/noconnect #this file stores the message fi #END-SCRIPT#
