Hi!
There is a way to overflow / filesystem even is quota is enabled.
Just make many hard links (for example /bin/sh) to /tmp/
for ($q=0;$q<100000;$q++){
system ("ln /bin/sh /tmp/ln$q");
}
Because /tmp directory usually owned by root that why quotas has no effect.
*Directory* size of /tmp can be grown up to available space on / filesystem.
Any way to fix it?
Dmitry.
