Sudo connect to a remote server and execute scripts in remote server
Hello Every one!!
I am trying to write a shell script which will connect to a remote server and execute scripts which are at a certain path in the remote server.
Before this I am using a sudo command to change the user.
The place where I am stuck is, I am able to connect to the remote server but neither am able to change the directory path nor I am able to execute scripts which I need to.
Also the log files which I have given in the script are not being created nor the log is being captured in the files even if I create them manually.
Below is the prototype of the script which I have written:
Code:
#!/bin/bash
#***************************************
ssh user@remote_server
if [ $? -eq 0 ];
then
echo "connection established successfully" >> path/to/log/file #(this log file is not being created nor is anything being inserted even if I create it manually)#
exit 0
else
echo "connection unsuccessful" >> path/to/log/file
fi
sh /path/to/remote/scripts/script_name
if [ $? -eq 0 ];
then
echo "script executed successfully" >> path/to/log/file #(this log file is not being created nor is anything being inserted even if I create it manually)#
else
echo "script not executed" >> path/to/log/file
fi
exit
Please suggest as where am I going wrong and what needs to be corrected.
Can't thank you all enough!!
Regards.

xon
XON(1) General Commands Manual XON(1)NAME
xon - start an X program on a remote machine
SYNOPSIS
xon remote-host [-access] [-debug] [-name window-name] [-nols] [-screen screen-no] [-user user-name] [command ...]
DESCRIPTION
Xon runs the specified command (default xterm -ls) on the remote machine using rsh, remsh, or rcmd. Xon passes the DISPLAY, XAUTHORITY and
XUSERFILESEARCHPATH environment variables to the remote command.
When no command is specified, xon runs 'xterm -ls'. It additionally specifies the application name to be 'xterm-remote-host' and the win-
dow title to be '-fIremote-host'.
Xon can only work when the remote host will allow you to log in without a password, by having an entry in the .rhosts file permitting
access.
OPTIONS
Note that the options follow the remote host name (as they do with rlogin).
-access
Runs xhost locally to add the remote host to the host access list in the X server. This won't work unless xhost is given permission
to modify the access list.
-debug Normally, xon disconnects the remote process from stdin, stdout and stderr to eliminate the daemon processes which usually connect
them across the network. Specifying the -debug option leaves them connected so that error messages from the remote execution are
sent back to the originating host.
-name window-name
This specifies a different application name and window title for the default command (xterm).
-nols Normally xon passes the -ls option to the remote xterm; this option suspends that behaviour.
-screen screen-no
This changes the screen number of the DISPLAY variable passed to the remote command.
-user user-name
By default, xon simply uses rsh/remsh/rcmd to connect to the remote machine using the same user name as on the local machine. This
option cause xon to specify an alternative user name. This will not work unless you have authorization to access the remote
account, by placing an appropriate entry in the remote users .rhosts file.
BUGS
Xon can get easily confused when the remote-host, user-name or various environment variable values contain white space.
Xon has no way to send the appropriate X authorization information to the remote host.
