[users@httpd] Perl UNIX shell PATH problem with apache www user

[Andy Smith <a....@ukgrid.net>]

Hi List,

   probably quite a basic question, but where does perl get its PATH  
variable from when executig shell commands?

My problem is running Tr.pm which is part of the open source tool  
smokeping, it does some nice things with traceroute. The weird problem  
I have is that I have the same version of smokeping and Rt.pm on two  
different servers and on one I have been getting the error "traceroute  
no such file or directory" and on the other it works fine. The  
commands are being called through apache httpd 2.2.9 whcih is running  
as www which has no homedir, and the /etc/profile is the same on both  
servers there are no /etc/bash files. What else can be different  
between them?
I can get the error to go away by putting traceroute in /usr/bin, but  
Id like to know why the perl code is fine on one server and not on the  
other.

This is my third attempt to work this one out :P I already asked on  
the FreeBSD forums and PERL forums and so far everyone has been  
stumped. So its gona be something obvious, or perhaps something odd  
like a compiled in PATH in httpd possibly?? :S

thanks for any suggestions! Andy.

Hi Davide,

  yep, apache is running as www, and has no homedir as I mention. And  
yet the path that apache has set is different between my two servers.  
My question is how if /etc/profile is the same and the user has no  
home dir and the perl script is the same on both systems,

thanks, Andy.

By the PATH defined for the user that "runs" the web server, that most
of the time is the 'default' PATH.

Traceroute is most of the time under /sbin, maybe you need to add it
specifically to the path or check the permissions
