Running system command

[Chip]

Hi and thanks in advance for your help.

I am trying to restart a Squid Proxy server
within a C cgi program.

I have added the following:
system("/usr/local/squid/sbin/squid -k reconfigure");

but get this error in the log file when I run the program:
"squid: ERROR: Could not send signal 1 to process 19175: (1) Operation not
permitted"

I have also tried:
system("su squid -c /usr/local/squid/sbin/squid -k reconfigure");
but get this error:
"su: must be run from a terminal"

How should I run the "/usr/local/squid/sbin/squid -k reconfigure" command?

Apache runs as nobody.nobody and Squid runs as squid.users
but the squid executable is chmod to 755.

Any and all help is greatly appreciated.

I'd try the squid-users mailing list.

this question isn't on topic here. This news group is concerned
with the C langauge and not with platform specific extensions.

I suggest you repost your question in a suitable Unix ng. Try
something like comp.unix...

Thanks for your help.

I needed to change userid with:
setuid(1002);

*** topposting corrected ***

Thanks for your help.

I needed to change userid with: setuid(1002);

For future reference, please do not toppost in c.l.c, and please do
observe topicality. While "system" is a part of standard C,
"squid" is definitely not, nor is setuid etc.
