This tool will help you to manage your application and code with the specific timeout and lock, and you will be assure and go for sleep  😀

Download hatools from www.fatalmind.com (http://www.fatalmind.com/software/hatools/hatools-2.14.tar.bz2)

[root@testbed ~]# wget http://www.fatalmind.com/software/hatools/hatools-2.14.tar.bz2

[root@testbed ~]# tar xjvf hatools-2.14.tar.bz2 && cd hatools-2.14

[root@testbed ~]# hatimerun -k TERM -t 15 -t 1 ssh testbed140 uptime
04:36:23 up  3:24,  0 users,  load average: 0.51, 0.40, 0.31

Check with wrong or any ssh port blocked server and get timeout watch. 🙂

Here I am written small script for testing purpose, you can change and use as you want.


# if you want to check and debug , run this script in following way
# bash -x script name <servername> <cmd>

server=$1  # server name or IP
cmd=$2   # command
sec=15      #Timeout seconds change as per your need

test -z $server && echo “server not found ” && echo “Usage: $0 {servername} {command}” && exit 1
test -z $cmd &&  echo “command not found ” && echo “Usage: $0 {servername} {command}” && exit 1
echo “connecting to $server, timewait set for connection is $sec Sec…….”

hatimerun -k TERM -t $sec -t 1 ssh $server $cmd
if [ $? != 0 ] ; then
echo “$server connection timeout …”
