problem using ssh

Hi All ,

Thanks for the replies.

I would like to answer each one of them individually.

@Tom de
Hi,the weirdness of the problem is that the script is getting executed when logging on from the environment B ,and is not getting executed when called remotely from server A.
If it is getting executed when logging on from the server B ,then why it si not identifying the script when called remotely?? Weird ,isn't it??

@ mehrdad68
Hi, I already tried using here document ,but to no awail.
My script goes in an indefinite loop and command prompt never returns back while executing this logic.

@ ShawnMilo

Hi, I am not running anything graphical.
The script that is being run just checks the diskspace of the system and informs the user if the threshold increases.

I hope I have made myself clear.

Could anyone guide me now towards the solution of this problem??

Many Thanks.

Taran

MY script :
ssh2 -d -l -n o2oenv8@10.40.6.172 "sh test4.sh"

Can anyone help me out here??

Thanks in advance...
This means two things are happening; your '-l' option isn't used correctly. '-l' needs a login name:
Code:
man ssh 
-l login_name
         Specifies the user to log in as on the remote machine.  This also
         may be specified on a per-host basis in the configuration file.

So, you get:
Code:
...
rcmd: -l: Unknown host
...

This can probably be ignored, it's not your problem - as the rest of this works. But maybe clean it up. SSH thinks '-l' is a host.

Now, the second part is:
Code:
test4.sh[9]: test: Specify a parameter with this command.
test4.sh[18]: test: Specify a parameter with this command.
test4.sh[28]: test: Specify a parameter with this command.
test4.sh[35]: test3.sh:  not found.

( I removed the "rcmd: -l: Unknown host" error, as it's a different problem)

Above your problem is in "test4.sh" you are executing a 'test' function. Either the word 'test' or something like 'if (-d file.sh)'. For whatever reason, you are trying to use a shell 'test' in way that requires a parameter see lines 9, 18, 28. And then on line 35 your script is looking for test3.sh.

Now, this could be because b's environment is setup to see all of the files
( maybe a path issue, maybe environment variables point to files ), and a's environment isn't setup to see the same paths/env-vars.

You can test this by putting the full path to a file in 'test4.sh'. Or investigating b's environment vs. a's.


maybe put up 'test4.sh' so we can see what its trying to do.

Problem using ssh

Hi,

My script in server B just do the same thing as it does in server A i.e check the quota of the system.

There is no need to enter any path as I am using remsh command to connect with the server.

Anyways I am hereby attaching both test4 and test3 for debugging purpose.

Hope you could help me in rectifying the error.

Thanks

I've highlighted where you errors happen, and added the errors you posted before.
Code:
#!/bin/bash 
 
remsh $HOST -l $TLG_USR_ID -n "quota -v" > fill4 
size=`awk 'NR==3 {print $2}' fill4`

rcmd: -l: Unknown host
Code:
echo $size 
  
a=370000 
if [ $size  -ge $a ] ;  then 

test4.sh[9]: test: Specify a parameter with this command.

Code:
echo "quota of  your application environment has increased  ,kindly delete the unwanted files " 
#else 
#echo " quota is lessss,u can continue" 
fi 
 
remsh $HOST -l $TLG_RATER_USR_ID -n "quota -v" > fill3 

rcmd: -l: Unknown host

Code:
 
size1=`awk 'NR==3 {print $2}' fill3` 
if [ $size1 -ge $a ] ; then 
echo "quota of your rater environment has increased,kindly delete the unwanted files"

test4.sh[18]: test: Specify a parameter with this command.

Code:
#else 
#echo " quota is lessss,u can continue" 
fi 
 
export TUXEDO_USR_ID=`basename $TUX_HOME` 
remsh $HOST -l $TUXEDO_USR_ID -n "quota -v" > fill2 

rcmd: -l: Unknown host

Code:
 
size2=`awk 'NR==3 {print $2}' fill2` 
if [ $size2 -ge $a ] ; then 
echo "quota of your tuxedo environment has increased ,kindly delete the unwanted files "

test4.sh[28]: test: Specify a parameter with this command.

Code:
#else 
#echo " quota is lessss,u can continue" 
 
fi  
 
. taran_test1

test4.sh[35]: test3.sh: not found. <--- path problem!


Having the script helps, as we don't have to guess at what is happening. Simply put your variables aren't working. $HOST, $a, and probably $TLG_USR_ID.

I'll assume 'taran_test1' has the var's we need, but we aren't getting the vars. Investigate taran_test1 for more clues.
