I can get the ssh command to remotely perform file with commands such as ls -la, etc, but I am having difficulty in some other areas:

I have two scenarios, one works, the other does not:

WORKING SCENARIO

I have 2 ssh session running and do the following:

First session:

I start an ftp session

[root@xxclnt1 etc]# ftp
ftp>

Open in new window



The second session

I kill the ftp session

[root@xxclnt1 home]# cat test.sh
pkill -9 ftp

[root@xxclnt1 home]# ./test.sh
[root@xxclnt1 home]#

The first session then successfully terminates the FTP

[root@xxclnt1 etc]# ftp
ftp> Killed
[root@xxclnt1 etc]#


NON_WORKING SCENARIO

The first session starts ftp as before

[root@xxclnt1 etc]# ftp
ftp> Killed

Open in new window


The second session then calls ssh to perform the test.sh (on the same machine as the caller, trying
to understand how this works so I can write more meaningful scripts involving terminating remote clients)

sshpass -p 'xxxxx' ssh root@xxclnt1 /home/test.sh

Open in new window



However, the ftp is still alive in the other session, and can also been see with the ps command

[root@xxclnt1 home]# ps -ef | grep ftp
root      6471  6046  0 14:19 pts/1    00:00:00 ftp
root      6491  6445  0 14:21 pts/2    00:00:00 grep ftp
[root@xxclnt1 home]#

Open in new window


1> Most importantly, why did the test.sh fail to work

2> and how can I get it to work ?

Thanks

Basically I am learning scripting, and I eventually hope to remotely kill running clients on the remote machines using ssh

So I am starting with ftp as a client I am attempting to kill, and will work up to the more robust industry standard clients as I go
