Shell Programming and Scripting

Hi,

I am trying to run a process through inetd using ksh.

The entry in /etc/inetd.conf is
Process_Name tcp nowait root /home/user/script script

The script is as follows
/usr/bin/ksh -c /path/process

Recycling inetd services is successfully completed.
But when the process is accessed by any application, the log file shows the following error:
inetd[8555]: exec /home/user/script: Exec format error

When i execute the script from the command line, it executes successfully and the process is started.

Could someone please help me with this?
Also how can I confirm that the process is running in ksh?

Thanks in Advance!

The script should start as follows:

Code:

#!/bin/ksh

Hi,

Thanks for the reply.
I tried out your suggestion.
Now there is no Exec format error.

But when any application accesses this service and runs an internal command, the log file says it tried to execute it in the bourne shell.

for eg;
An application accesses this process and runs a command jr %
the log file says
/bin/sh: jr: not found.

It will only run if it is executed in the korn shell.

Is there any way of confirming whether the said process is spawned using the korn shell or the bourne shell?

Any help would be appreciated.

Thanks in advance.

Is the script now saying....

Code:

#!/bin/ksh

/usr/bin/ksh -c /path/process

What is $SHELL set to as it is executing? Does your script /path/process also have #!/bin/ksh or similar at it's start?

Try switching running from /bin/sh in your terminal session, set SHELL to /bin/sh and then test your program.

What is your PATH set to in a terminal session and in the environment running inetd? Put "PATH=/usr/bin:/bin" near the start of your script and add paths as needed.

Yes, thats what the script looks like now.

/path/process is not a script, it is an executable and runs in the background when it is called through inetd.conf

Try switching running from /bin/sh in your terminal session, set SHELL to /bin/sh and then test your program.
When I run it from my command line, the process starts up, but according to the script "/usr/bin/ksh -c /path/process" it should be spawned in the korn shell.
How do i verify this?


Thanks.

If it's an executable (as in compiled code) it should not matter what shell started it.

I think also you need to provide the path to "jr" in the environment in the shell you start from inetd.conf.

Hi,

Thanks a lot for your help.
