Passing --fdpass or --stream to clamdscan works for
calling up a scan on the command prompt however calling it through mediawiki (via the
chrooted web user www) still fails with an error 127. If I make a file called test.php
$output = wfShellExec( "command=/usr/local/bin/clamdscan --fdpass --no-summary
'/htdocs/file.txt' 2>&1, $exitCode );
echo "exitcode is $exitCode";
Executing "chroot -u www /var/www /usr/local/bin/clamdscan --fdpass --no-summary
'/htdocs/file.txt' 2>&1" will work just fine but running the script
will always fail with error 127. Even substituting in the $output line something like
wfShellExec( "/bin/echo 'hello world' > world.txt" ); will always
fail with error 127 as well, despite echo being at /var/www/bin/echo and permissions
readable and executable by the proper www user. Appears that there may be something up
with how mediawiki is executing shell commands, maybe I'm going about testing this the
Thanks for the insight.
Exit code 127 is usually the shell not finding out the executable.
Try removing command= from the beginning (you also miss the closing of
the double quotes, by that seems an overlook on copying).
