Good point.Okay, in a perl cgi script run by version 2.2 the command system("ls") returns an error code (256, as I recall which corresponds to actual exitcode 1) which I can print after the system("ls") call.
Using apache 2.0 the perl statement system("ls") returns 0 as it should.
Using a nonsense command system("foo"); produces an error code of -1
with both 2.0 and 2.2
An additional bit of info that suggests there's a path/permissions problem is that perl cgi scripts run with the apache 2.2 report an error with a require("/home/pelikan/test.txt"); (can't find file) but can do require("/var/www/cgi-bin/test.txt"); As if whoever's running the script can see cgi-bin but not /home/pelikan (though the /home/pelikan is set to let anyone read and execute)
The file test.txt exists in both places.Apache runs as user 'apache' and there's no login allowed for that user so I don't know how to run a program or view the path for user apache. I'll read up on how to do cron and see if I turn that into a test.

Putting a "print" statement before the call to system(ls) doesn't tell us anything about whether or not the running program can *find* the ls command in order to execute it, it only proves that you are about to try (and probably fail, perhaps for one of the reasons I've mentioned). It may well be that the error you are geting is "command ls not found".On 11/02/07, *Steve Pelikan* <pelikan@xxxxxxxxxxx <mailto:pelikan@xxxxxxxxxxx>> wrote:Thanks. It is finding and executing the scripts. (Can put in a print statement before the system() command and see the results on a web browser calling the script. Both the 2.0 and 2.2 apaches are using mod_cgi. In 2.0 it is built in and in 2.2 there's a LoadModule statement for it in httpd.conf. But: mod_suexec is loaded in 2.2 and not loaded or built in in 2.0. This is a difference I hadn't thought about or even known about. I don't really know about suexec or how it should be configured, but it looks like it could be close to my problems. Thanks for the pointer.
