"Illegal Seek" problem in script.

[nawlej]

Has anyone ever run into a problem when running a command inside of a script where an "Illegal Seek" error is generated? A little background:

-The command is using sudo. It asks for my sudo password before it runs, but returns as an illegal seek.

-When i run the command from the command line, it executes just fine.

-Subsequent attempts to run the script generate the same error, even after the user is considered "trusted" and doesnt have to enter a password any longer.

Any help would be greatly appreciated as always. Ive gone through 6 cans of Jolt trying to figure it out.

You're syaing it runs fine from the command line, but not from ... a browser session?

If this is the case it's probably because the web user doesn't have sufficient privs to run sudo, and that's not a bad idea from a security standpoint.

[whatever sudo is]

Could you write a script that runs as a daemon almost that can recieve calls from the script, and act on those

Just a thought

sudo allows you to run as super user on *nix OS's.

Isn't there a priv flag as to whether a user can use sudo or not?

Hi nawlej,

Can you identify which part of the script is generating the error?

Ok, I got it fixed. Just for clarification.....This isnt a CGI script. I built out a function to run the command in the shell, and grabs the output in the form of an array. After which, if the command does not execute properly, I had it built to return the error it recieved into the array. If was checking it in the form of if(@output<0){}

It works beautifully, until I run commands when the command that runs does not return output by default, in which case, it would always return an error because it met the error checking condition. Upon querying the shell for the error, thats where the "Illegal Seek" message came from. I was trying to query a null output. To fix it, I just ran the non output commands with the system() function. The scripts runs like a dream now. Thanks for all of your help.
