RHEL6 ssh cannot start a remote background process

[Guest ndrw_cheung]

Hi. I�m using RHEL6 (version 6.5) on all servers and I came across a problem invoking a process in the background via ssh. The set up is as follows:

 

Server 1 :

Script : start.sh:

#!/bin/sh

ssh user1_AT_x.x.x.x �t sudo �/etc/init.d/test1�

#note : I cannot post the "at" sign due to being a new user, so _AT_ is the at sign

Server 2 :

Script : /etc/init.d/test1:

#!/bin/sh

./runremote.sh &

 

 

user1 exist on both server 1 and server 2 has sudo privileges.

 

When we do (logged in as user1 and sudo on server 1)�./start.sh� from Server 1, the script �runremote.sh� is NOT invoked. I tried removing the �&� to run runremote.sh in the foreground. That works, but the start.sh hangs and will not close the ssh connection. I also tried the following variations, but none of them work the way I wanted:

�nohup ./runremote.sh�

�nohup ./runremote.sh &�

�./runremote.sh > /var/log/runremote.log 2>&1�

�./runremote.sh < /dev/null > /var/log/runremote.log 2>&1�

 

 

How should I change the contents of these scripts so that when I do �./start.sh�, �runremote.sh� is invoked in the background and �start.sh� will close the ssh connection afterwards? If possible, I DON�T want to use any additional software such as �screen�.

Thanks in advance for answering.
