ssh: connect to host .....No route to host


Hi All,

I am exceuting a script file after connecting a server using ssh .

ssh -f <IPADDRESS1> '/root/Desktop/a.sh &'


ssh -f <IPADDRESS2> '/root/Desktop/a.sh &'

....................


Now Out of 10 ips , 7 ips are connected. For rest of the ips (ie 3) it is showing
ssh: connect to host .....No route to host

and I am not able to put this connection error in a log file.


So , I want a solution that will produce an error/alert message if the ip is not connected as for rest of the ips the script file is being executed properly and getting the desired result.....

Thanks in advance

To put the error to a log file, append this to your ssh command:
Code:
ssh -f <IPADDRESS1> '/root/Desktop/a.sh &' 2>loggile.log

Thanks... But I need the output also in that log file(of that file of those ips which got connected)

In that log file only error message is coming..

I want to know one thing-----------

if [ <ssh -f <IPADDRESS1> '/root/Desktop/a.sh &'> ] is true(got connected and executed)
then
"connected"
else
"not connected"


is it possible to write this type of code in shell script ??

   echo "connected"
else
   echo "not connected"
fi
