Also we wrote a tester for SshHelper.sshExecute method. It was returning
output of SSHexecute command as it gets received by sshExecute. Here they are
100 sequential runs (success if result is 100) :
Before the fix:
[root@ussarlabcsmgt41 t_vazqnadmin]# for i in `seq 1 100`;do curl
"http://10.144.31.41:8096/client/api?command=testNicoSSHCommand&hostip=10.140.32.220&sshcommand=echo%20success";
2>/dev/null|head -1|grep success;done|wc -l
## **58**
[root@ussarlabcsmgt41 t_vazqnadmin]# for i in `seq 1 100`;do curl
"http://10.144.31.41:8096/client/api?command=testNicoSSHCommand&hostip=10.140.32.220&sshcommand=pwd";
2>/dev/null|head -1|grep '/root';done|wc -l
## **49**
[root@ussarlabcsmgt41 t_vazqnadmin]# for i in `seq 1 100`;do curl
"http://10.144.31.41:8096/client/api?command=testNicoSSHCommand&hostip=10.140.32.220&sshcommand=ls%20/proc/sys/net/ipv4/conf";
2>/dev/null|grep eth;done|wc -l
## **0**
After the fix:
