To je moc divne. nc je sice obcas moc aktivni v tom, jak uzavira
spojeni, ale nemuselo by z toho hned byt RST.

Zkuste serverovemu netcatu za "cat /tmp/orig.txt" pridat jeste nejaky
dostatecne dlouhy sleep. Pustte na nej strace a podivejte se, zda neco

A konecne je v takovem pripade dobre si poslechnout, co chodi po siti.
